Alkyd paint for batteries. How to paint a radiator: step-by-step technology for painting radiators

Many owners of houses or apartments are in no hurry to replace old-style cast-iron batteries, which function normally, with new models. Despite their venerable age, these radiators can serve faithfully for many more decades. True, it is necessary to periodically put them in order. Over time, they lose their aesthetic appearance, cracks form on the paint layer, and paint peels off. And in these places traces may appear, which may not be dangerous for cast iron, but very much spoil the overall picture of corrosion. This means it’s time for another coloring.

Other types also require updating of the protective and decorative coating, especially since for steel batteries or convectors, pockets of emerging corrosion can generally become fatal. Yes, and aluminum or bimetallic heating devices also sometimes have to be “refreshed” over time or even repainted in a different color, in accordance with the intended decoration of the room.

In this publication we’ll just look at how to paint a heating radiator yourself? The main nuances regarding preparation for this procedure, the choice of paint and its practical application will be discussed. And this information needs to be known even before the planning stage of such work.

Paint for heating radiators

Criteria for choosing paint for batteries

Not just any paint is suitable for heating radiators. It's all about the special operating conditions that are characteristic of these heating devices.

Therefore, when choosing a composition, you need to choose one of the options made specifically for application to heating radiators. If the manufacturer has not specified the purpose of the paint, then you should pay attention to such characteristics as heat resistance.

So, when purchasing paint, you need to study the following parameters:

• Resistance to elevated temperatures. The paint layer applied to a metal surface must be able to withstand heating up to 80÷90 degrees, without losing its protective and decorative qualities and without emitting odors.
• High adhesion. This quality will help create reliable adhesion of the paint to the surface of the battery - the coating will not begin to peel off under the influence of temperature changes.
• Anti-corrosion protection. The paint must contain components that can protect the metal from external aggressive influences. This is especially true for steel and cast iron radiators.
• Color resistance to fading or yellowing. This is a very important quality of paint, and if it is not taken into account, it is possible that the painting will soon have to be done a second time.
• Resistance of decorative coating to abrasion. When the radiator comes into contact with various hard objects (for example, when rearranging furniture or during children's games), as well as items of clothing, which are often dried on radiators, the paint layer should not become covered with small scratches, become thinner and begin to “see through.”
• Environmental Safety. The paint should not contain components that, when heated, can emit toxic fumes that can harm the health of residents of the house or apartment. The coating should not create any odors in any operating mode of the batteries.

The good quality paint you choose must meet all of the above criteria in combination. However, for some of the characteristics, such as adhesion, to really work, the surface of the radiator must be properly prepared. If you miss this important stage of painting, the coating may not last long, and the entire process will have to be repeated, taking into account the mistakes made.

What paints can be used for radiators

If previously oil paints were mainly used to paint batteries, and at best enamel options (simply due to the paucity of the assortment on sale), today the choice of compositions is so wide that it is worth understanding their characteristics and identifying the optimal one.

Oil paint

Despite the availability of other types of paints in specialized stores, some homeowners prefer the “old fashioned way” to purchase time-tested compositions made from organic oils for painting batteries. This line of paints is an inexpensive option, which is probably why it is not losing its popularity.

Characteristic features of oil compositions:

• They have excellent hiding power and create a layer on the metal surface that has high density and strength.
• The paint is resistant to high temperatures.
• The compositions do not emit toxic fumes after drying.
• The coating demonstrates good resistance to mechanical loads and abrasion.

Oil-based compositions also have their own quite numerous disadvantages. Therefore, many homeowners have long abandoned them:

• When painted, the compositions emit a specific tart odor that does not evaporate from the premises. long time.
• The paint takes a very long time to dry, leaving unsightly marks, especially on vertical surfaces.
• The composition has a rather thick consistency and poor spreadability, so it is not easy to apply it in an even layer.

Over time, a layer of oil paint takes on an unrespectable appearance, turning from white to a dirty yellow or cream color.

• White oil-based coatings are prone to yellowing, which means that the decorative value of such a coating will be very doubtful after a couple of seasons.
• The material does not have high anti-corrosion qualities, so rust often forms under its layer, showing through in spots.

Despite the fact that oil paints are affordable, today literally only a few consumers choose them - all because of the above-mentioned disadvantages. In addition, they are significantly inferior in their characteristics to analogues made on other bases.

Conclusion - it’s better not to mess with it, despite the affordable price.

Alkyd enamels

This type of paint composition contains pigments and additives embedded in pentaphthalic or glypthal varnish. Alkyd paints have a number of advantages that make them a fairly popular material:

Alkyd enamel specially designed for painting batteries, as reflected on the label

• The alkyd composition creates a uniform, smooth coating on the surface of radiators, giving them an aesthetic appearance.
• The paint does not turn yellow or fade, and also has high adhesive properties.
• The coating can reliably protect the metal from external aggressive influences.
• Alkyd paints are highly wear resistant.
• The ability to withstand high temperatures makes this decorative coating durable.
• The wide range of shades available for sale allows you to choose the paint most suitable for the intended finish.
• The advantage is the affordable cost of such paints and varnishes.

Alkyd enamels are divided into several types, depending on the base on which they are produced. Moreover, each of the options has both its “pros” and “cons”.

• Solvent-based enamel (white spirit) creates an aesthetic glossy layer on the surface. However, when applied, the composition emits a sharp, pungent odor. Despite this, the material remains in demand due to its affordable cost and relatively quick drying.
• Organosilicon-based enamel creates a matte layer on the surface of the batteries. The paint is heat-resistant and can withstand heating up to 600 degrees without damage (which is impossible in principle on heating radiators). Such formulations are offered both in the form of a suspension, packaged in jars, and in the form of an aerosol.

If you plan to purchase odorless paint, then the solvent-based option should be immediately rejected. White spirit, which is part of the paint, gives it a sharp, unpleasant odor that persists for a long time even after painting. In addition, when the batteries are very hot, the smell can also appear even after some time.

Acrylic enamels

Heat-resistant acrylic enamels are very popular among consumers, as they have a large number of advantages, which include the following characteristics:

Acrylic enamels can create a matte, semi-matte or glossy finish on the surface

• Acrylic enamel creates a smooth and even coating on a metal surface. As the composition dries, polymerization of its components occurs, as a result of which the applied layer visually resembles plastic.
• Acrylic heat-resistant paints do not emit a sharp unpleasant odor both during application and during operation heating devices.
• This type of paint composition dries quickly - their setting period ranges from 10 to 90 minutes, depending on the components and production technology. The complete drying of the layer occurs approximately 5 hours after its application.
• Acrylic enamels have a medium thickness; they are convenient to apply to vertical surfaces, as they adhere well to them, do not spread and do not create smudges.
• A large selection of acrylic paints from different manufacturers allows you to choose the option that suits the buyer most, both in terms of cost, composition and shade.

Despite a considerable number of advantages, acrylic enamels also have their disadvantages, which include the low resistance of the coating to mechanical stress.

Having chosen acrylic compositions, when purchasing them you should pay special attention to such characteristics as the temperature range of operation, as well as the specific purpose of the paint.

To obtain the proper coloring effect, the enamel is applied to the prepared surface in two layers. In addition, after applying both the first and second layers, it is necessary to ensure that the surface is protected from moisture during the drying period.

Among acrylic enamels, popular compositions can be distinguished - these are “VD-AK-1179” and “Thermakrill”.

• “VD-AK-1179” enamel is applied to the well-primed surface of the battery. The first coat of paint dries for about two hours, after which the second coat can be applied. Complete drying of the composition occurs one day after applying the second layer.

Universal acrylic enamel “VGT VD-AK-1179” is fully suitable for painting heating radiators

• “Thermakrill” paint of the “Alp Enamel” brand differs from its analogues in the anti-corrosion additives it contains. This type of enamel is designed for application not only to cast iron radiators, but also to batteries made of stainless steel, aluminum, titanium alloys and low-carbon steel. The paint has a specific smell, but it dissipates fairly quickly. The applied composition sets within 30 minutes, and complete drying occurs two days after applying the second layer of enamel.

Dispersion acrylic paint

This type of acrylic paint is different in that it can be used during the heating season, that is, when the radiators are heated to high temperatures. Dispersion acrylic compositions are practically odorless, easy to apply in an even layer and dry quickly.

The paint has high decorative and performance characteristics, does not change color during operation and does not crack under the influence of high temperatures. It is capable of creating matte or glossy surfaces - this is what the store pays attention to when choosing.

One of the popular compositions of this type is paint for radiators “Dulux Master Lux Aqua 40”

Master Lux Aqua 40 paint from Dulux is especially popular among consumers. When applying it, some features should be taken into account. So, for the first layer, the paint is diluted with water in a ratio of 1:10 - this turns out to be a kind of primer that prepares the surface for the next painting layers. And they are already applied with undiluted paint.

You can name a few more compositions that, according to consumer reviews, have proven themselves with best side- this is “Aqua-Heizkorperlack” of the Dufa company, “Element” of the Eskaro brand, as well as Tiora, Thermo and Dufa Retail. All these paints do not have unpleasant odors, dry quickly and create very durable and neat coatings.

Silicone paints

These types of paints are made on the basis of silicone mixed with aqueous or organic solvents.

The features of silicone compounds include the following qualities:

• High temperature resistance. Silicone coating can withstand any temperature conditions of heating systems without losing the integrity of the layer and its aesthetics.
• Convenient and easy to apply. If you choose this coating option, then it doesn’t even require additional preparation. metal surfaces radiators.
• Long service life. Silicone is resistant to mechanical influences, including abrasion. The surfaces are easy to clean. Including using detergents.
• It is not at all afraid of ultraviolet radiation - the surfaces will not fade. It’s not for nothing that silicone paints are widely used to decorate building facades.

The only drawback of silicone compounds is their high cost. But, considering the duration of operation without loss of external data, the fact that you do not have to spend time and money on painting batteries every two to three years, the price seems quite justified.

Other paint options for radiators

In addition to the types of paints listed above, suitable or specially designed for painting batteries, other paints and varnishes made on other bases can also be used. Or modifications of the already mentioned compositions with additional ingredients.

From a variety of paints for radiators, you can choose the one that suits both characteristics and price

• Paints made on the basis of silicate resins . This version of paint forms an elastic and dense layer on surfaces that is resistant to temperature changes. The compositions have excellent adhesive properties and do not require additional surface preparation. The disadvantages of this material include an unpleasant, pungent odor during the period of applying the paint and until it dries completely.

One of the texture options created with hammer paint

• Hammer paints - This is a type of alkyd composition, but it creates not a traditionally smooth coating, but interesting textured patterns small cracks or a surface with an embossed effect. This option is impossible would be better suited for older models of cast iron batteries. The texture they create will perfectly hide the roughness that is always present on these radiator models.

• Some homeowners prefer to paint the batteries - silver coin , which consists of aluminum powder and varnish or drying oil. This composition perfectly withstands high temperatures, and it can be applied both to a prepared base and to old paint. It is necessary to immediately warn that the composition has a persistent, pungent odor, so after painting the room must be immediately well ventilated. As for the decorativeness of this approach, let everyone decide for themselves how appropriate such decoration is, say, in a residential area.

Preparing batteries for painting

The process of preparing radiators for painting is very important stage work, as it is necessary to perform several tasks:

• One of the tasks is to increase the adhesive properties of materials, as well as protect the metal from corrosion.
• If the batteries are old, covered with several layers of paint, cleaning them is necessary to increase heat transfer.

It is recommended to carry out all work both on preparing surfaces and painting them at the end of the heating season. An exception may be the use of paints and primers designed for application to hot surfaces.

So, preparing radiators for painting consists of several operations:

• Cleaning surfaces from dust and greasy deposits. Dust accumulated inside the sections is removed using a vacuum cleaner with a crevice nozzle or a narrow brush. You can also use the wet cleaning method using water with detergents. If grease stains have formed on the battery, which often happens in kitchen conditions, you can remove them with dishwashing detergent. If necessary, apply a damp cloth to heavily soiled areas, under which greasy spots soften and will be easier to clean off.

• Removing rust and old paint . Next, new batteries must be cleaned of rust, and old batteries must be cleaned of numerous layers of paint. There are two cleaning methods - mechanical and chemical.

— Mechanical method more labor-intensive and will take quite a lot of time. It is carried out using a metal brush mounted on a grinding machine or in the chuck of an electric drill. However, this method is only suitable for . Modern batteries made of thin sheet steel or rigid non-ferrous metals wire brush can cause serious damage. In any case, you should work at low speeds. The paint on the surface of the batteries must be completely removed.

— Another cleaning method is to use chemical compositions , with the help of which paint or rust is washed off from surfaces. The compositions are produced in the form of a solution, paste, gel or aerosol.

Remover for removing paint from wood and metal surfaces

Each of the chemical composition options is used differently - on the packaging the manufacturer gives instructions for their use, which must be strictly followed. For example, paste-like substances are applied to surfaces using a natural bristle brush, after which the battery is closed plastic film for a period determined by the manufacturer. The exposure time can vary from twenty minutes to several hours. The paint should soften, after which it is removed from wide surfaces with a spatula, and its remains mechanically using a wire brush.

Aerosol versions of washes are convenient to use, since when sprayed they penetrate into the most inaccessible places in the radiator sections. The principle of operation of these compositions is comparable to any type of remover - the paint is softened, then removed with a spatula and brush.

However, it should be warned that chemical compounds are not harmless. They have a pungent, pungent odor, so the room where they are used must be well ventilated. In addition, it is necessary to secure Airways a respirator, and hands with protective gloves. When choosing this cleaning method, it is necessary to purchase compounds that indicate that they are safe when applied to metal.

• Radiator priming . The next step is applying primer to the cleaned surfaces. This treatment is intended to prevent the appearance of corrosion areas, as well as to create optimal conditions for the adhesion of painting materials. The composition chosen for priming must be intended for metal surfaces and be compatible with the paint that will be used to paint the radiators.

If you purchase domestically produced paint, then GF-021 primer is well suited for it. When using paint compositions from foreign manufacturers, you can use Sigma or Dulux primer.

The final stage of painting begins after the primer layer has completely dried.

Painting radiators

When starting to paint, it is recommended to adhere to the following rule - apply the paint in thin layers. If you try to paint radiators in one thick layer, you will hardly be able to get a neat, smooth surface. A large amount of paint, once applied to the vertical surfaces of batteries, creates unsightly smudges and unevenness. Therefore, the best option is to paint the devices in two thin layers: the first will create a base and cover the natural color of the metal or primer, and the second will finally even out the finish and give the radiators an aesthetic appearance.

Cast iron radiators

These are perhaps the most inconvenient batteries to paint - due to their complex shape, pronounced ribbing and visible internal cavities.

To paint cast iron radiators you will need several brushes different widths, and most importantly - mounted on handles of various configurations.

In order to get to hard to reach places Inside the sections you will definitely need a brush with a curved long handle, which will greatly simplify the painting process.

The first step is to paint the upper areas inside the batteries, then the lower ones. Next, they move on to the external, front surfaces.

Painting facade surfaces, after finishing the interior areas, will seem like a real vacation

The outer surfaces of the radiator also begin to paint from the top, gradually moving down. This technology is explained by the fact that in the event of a careless mistake or leak, it can be immediately picked up with a brush, that is, the defect can be corrected.

The first layer should be thin, but cover all surfaces of the radiator without leaving unpainted areas.

The second painting is carried out only after the first layer has completely dried. The setting and drying time of the paint is indicated by the manufacturer on its packaging.

If after the first layer has dried, smudges or unevenness are detected, then before the second painting the surface should be treated with fine-grained sandpaper.

Since cast iron radiators, as a rule, most often require regular painting, to help the home craftsman, there is an online calculator below that allows you to calculate in advance the required amount of paint. The necessary explanations for the calculations are also attached.

Installation of a new heating system or reconstruction and repair of an old one may require painting of heating radiators:

• When installing new devices that do not have a special coating,
• If the integrity of the coating of existing radiators is damaged,
• If it is necessary to change the color of the devices due to a change in the design of the room.

This raises the question, what kind of paint is needed for heating radiators? different types and how to apply it correctly.

How to paint a radiator?

Radiator paints

Technical requirements

In order for the paint to protect the heating radiator from damage, and also to retain its original appearance for a long time, it must meet the following requirements:

• Intended for painting metal,
• Protect from corrosion,
• Be resistant to abrasion and cracking,
• Be heat-resistant (when using water as a coolant, withstand temperatures of at least 100 0 C).

In addition, it must be non-toxic (without impurities harmful to humans).

Different types of paint

The heating radiator can be painted:

• Enamel. Enamels are inexpensive and have a wide range of colors to choose from, but they do not tolerate high temperatures and reduce the heat transfer of the device. They take a long time to dry, smell unpleasant and can only be used to paint a cold radiator.
• Acrylic dyes. They are odorless and dry quickly; they can even be applied to a hot radiator. They do not last long, as they have a low coefficient of adhesion to the surface being painted and can crumble over time. After drying, they change color a little.
• Alkyd paint. Heat-resistant, fits well on the surface, but takes a long time to dry and smells unpleasant.
• Special paint for radiators. It tolerates any increase in temperature, so even hot heating elements can be painted with it. Dries quickly, does not reduce the heat transfer of the device and does not turn yellow over time. Available in limited edition color scheme and is more expensive than other types.

Interesting! The color of paint for radiators can be any - light or dark, suitable for the design of the room. But experience shows that for better heat transfer it is better to use dark shades.

Preparing the radiator for painting

Before painting heating devices, they need to be prepared for this accordingly:

1. Clean from dust, dirt and grease.
2. Remove old layers of paint. This must be done, since each new layer reduces the heat transfer of the heating and lies unattractively on top of the previous layers. It can be done:
   • mechanically using metal brushes and sandpaper,
   • chemically using solvents or fatty acids, observing safety precautions.
3. Apply a layer of special anti-corrosion primer.

Attention! The primer should be selected so that it matches the type of paint you choose. In this case, it is better to choose paint and primer from the same manufacturer.

Painting of devices made of different materials

Heating radiators made from different materials have their own painting characteristics:

• To paint cast iron, you can use universal enamels. Before painting cast iron radiators, it is better to turn off the heating. On a hot surface, paint dries faster, so it can wrinkle and form uneven spots. If it is impossible to turn off, paint on the radiator in a thinner layer.
• Steel, aluminum and bimetallic batteries They are produced with a layer of industrial powder coating already applied, so painting them at home is quite problematic. Before painting such a radiator, you need to carefully clean it with grinding machine. For painting it is better to use alkyd enamel or acrylic (acrylate).

Remember! To clean non-ferrous metals from old layers of paint, it is better to use mechanical rather than chemical methods. Chemical solutions may react undesirably with the surface of the radiator.

Why do you need to paint radiators?

Renewing the paintwork on heating radiators is carried out in many cases. This is often done as a result of severe wear or damage to the old paint or when the finish has lost its attractive appearance. Before deciding what paint and color to paint heating radiators, you need to find out why such a procedure is being carried out.

Heating radiators in an apartment or private house are painted in the following cases:

• If the shade of the coating has changed. This is due to possible fading and thinning of the protective paint.
• If there are inhomogeneities in the coating - bubbles, chips, cracks and other paint defects.
• When carrying out major repairs of heating elements.
• To update the interior and appearance of radiators.

Not only the decorative component is of great importance, but also the operational characteristics of the protective coating - resistance to temperature changes and high humidity.

Color range for heating radiators

White cast iron radiator is classic version heating device located under the window. Painting the window sill white and window frames– the simplest and most affordable solution.

Batteries available in black and black are becoming quite popular. brown tones. There is an opinion that a battery painted in a dark color heats up faster and releases heat longer. Dark-colored batteries will be appropriate in industrial-style interiors.

The most successful and original solution for country houses and apartments is batteries painted in the color of the walls. Such a move does not require complete hiding or masking of the heating system elements. All you need is to successfully fit the heating devices into the overall style of the room.

Many homeowners decide to take a bolder step - paint the radiators in a color that contrasts with the walls. This design option will be relevant for interiors in the style of minimalism, modernism, colonial, rustic and art deco.

An original version of painting a battery using gradients or ombre techniques. For the outer section, a neutral color is chosen, each subsequent one becomes more and more bright and saturated with the addition of light grading shades.

Painting heating radiators in different colors - good decision for children's bedrooms and playrooms. Here you can implement the most unexpected ideas: apply patterns, drawings and paintings. Beautifully decorate batteries as rainbows, colored pencils or fairy-tale characters.

Is it possible to paint hot radiators?

When painting heating radiators and pipes, the surface temperature should be taken into account. It is definitely not worth painting appliances in winter, and especially during the heating season. Applying paints and varnishes to a hot surface can lead to accelerated drying of the coating and the appearance of minor defects in the form of sagging and stains.

In addition, when processing a hot radiator, the sharp smell of paint may increase, and ventilating the room in winter period is fraught with heat loss.

The most suitable time for carrying out repair work is a warm period, when the radiators remain cold, and it is also possible to ventilate the room well.

If it is impossible to postpone painting the radiator until the beginning of the heating season, then you need to wisely choose working equipment and materials. For work, it is better to use a spray can, which allows you to quickly and evenly apply the heat-resistant composition to the surface to be treated. The lower part of the structure and pipes should be treated with a brush.

When choosing paint and varnish products, it is important to consider its quality and performance characteristics. For example, it is better to paint a hot radiator with alkyd enamel.

A more affordable and safer option to paint a switched-on radiator is to use a quick-drying acrylic compound. This coating is resistant to temperature changes and high humidity.

Choice of paint for radiators. comparison table

To paint heating system elements, high-quality paint for heating radiators is used, which meets high requirements. It must be safe, resistant to overheating, cracking and fading. Experts recommend choosing the following types paints for heating pipes and radiators:

Types of paints and varnishes (paints and varnishes)	Types of surfaces	Benefits of paints	Disadvantages of paints
Oil paints	Cast iron	Affordable price, wide range of colors	Long drying time, strong odor, susceptible to yellowing, cracking and chipping

How to clean a surface from old coating

Preparing the surface of radiators and pipes begins with removing the old paintwork. There are two simple ways to clean radiators:

• The mechanical method involves using a brush with metal bristles or an attachment to an electric drill. Dismantling the coating is carried out down to the metal, so it requires a lot of time and physical effort. The only drawback is the difficulty of processing small parts or hard-to-reach places. A special attachment for the drill simplifies the cleaning process, and it also allows you to better process the entire area of ​​the device, even in hard-to-reach places.


• Chemical method requires the use of special chemical compounds based on acids and solvents that reduce the adhesion of the coating to the base. The surface is carefully treated with the selected composition according to the instructions until the paint is completely softened. Next, the old coating is removed with a spatula, grinder or brush.

Calculation of paint for pipes and batteries

Another important step is to correctly calculate the required volume of materials used for painting radiators, pipes and other elements of the heating system.

For the calculation, the initial data is used:

• Surface area to be treated.
• Consumption rate of a specific type of paint per 1 sq. m.

The paint consumption is calculated and indicated by the manufacturer on the packaging. Each element of the system has its own area, which is taken into account when calculating the volume of paint. Such information is contained in the technical characteristics of each heating device. If painting of pipes is required, it is necessary to additionally calculate the area of ​​each of them, multiplying the length of the pipe by its diameter and the number P.

The obtained values ​​(device area) and paint consumption per 1 sq. m are multiplied to obtain the exact volume of paint in units of calculation - liters. This volume is taken into account for applying one layer. If you need to paint in several layers, the paint consumption per layer is multiplied by total layers.

Do-it-yourself painting of heating devices

The workflow for painting batteries and pipes with heat-resistant compounds includes several stages:

1. Preparation of the treated surface.
2. Application of coloring composition.

To carry out the work you will need the following tools and materials:

• Brush with a metal base.
• Paint brushes – regular and radiator.
• Coarse sandpaper.
• Cleaning brush.
• Spatula with a metal tip.
• Primer for metal.
• Degreasing or solvent composition.

Preparing surfaces for painting

To execute high-quality painting heating appliances with your own hands, you need to properly prepare the surfaces. Preparatory work includes the following activities: cleaning of old coating, removal of corrosion, degreasing and priming.

1. The surface is thoroughly cleaned: the old coating is removed, areas damaged by corrosion are sanded to a shine. Dirt is removed with a brush, and paint with a spatula or special chemicals.
2. After removing the paint, the surface is sanded with a brush with metal bristles, a special attachment for a drill or a grinder. When working with surface cleaning, personal protective equipment is used.
3. The cleaned surface is sanded with sandpaper and degreased with any available solution.
4. A primer with anti-corrosion properties is applied to the prepared surface for maximum protection against corrosion and increased adhesion of the paint composition to the base.

Features of surface painting

Most modern compounds are applied to a cold surface, so before painting hot battery needs to be cooled. To obtain high-quality coating, it is recommended to paint batteries following a certain technology.

Liquid formulations

If the work uses oil, water, water-based and other liquid composition, it is necessary to properly prepare the workplace and protect surrounding surfaces with clean rags.

1. For painting, use a brush with a curved handle or a soft sponge. The coloring agent is poured into a wide container. Hands are protected with gloves.
2. The composition is applied in a thin layer to the internal surfaces and in hard-to-reach places, then the outer part of the heating device is treated. Smooth strokes are made from top to bottom, which will allow you to evenly apply the enamel to the surface.

Important! If visual defects appear after painting, re-painting is necessary.

What is required from paints for radiators

The following requirements apply to paint materials for heating batteries:

• no toxicity;
• high thermal conductivity;
• resistance to high temperatures;
• wear resistance;
• protection against corrosive phenomena.

An additional requirement is that the paint should preferably be odorless.

The first requirement is due to the fact that when the battery is heated to high temperatures, the material with which it is coated begins to release toxic substances into the air. Their exposure negatively affects the health of the occupants of the premises. When choosing products for a battery, you need to make sure that it is safe for humans when heated.

Many products form a film on heating radiators, preventing the process of heat transfer into the open space of the room. When choosing, it is important to make sure of its ability to conduct heat through itself.

High-quality products can withstand temperatures in devices exceeding 1000C. Otherwise, the product will begin to crack and crumble under the influence of high temperatures.

Appliances need to be cleaned and washed. To do this, fairly aggressive cleaning agents are used, which can lead to loss of color and even abrasion of the paint coating on radiators.

Any high-quality material protects heating batteries from corrosion. For this purpose, special products are manufactured for metal coatings. Good paint materials are expensive, but protect the heating system from corrosion for many years.

What are the types of compositions?

The modern coating market offers many options:

• alkyd;
• hammer;
• acrylic;
• silverfish;
• water-based;
• silicate;
• powder

Alkyd enamels have good resistance to heat, and acrylic enamels give the surface of heating radiators a glossy shine.

A certain type of material is suitable for a specific type of radiator. Batteries are made from various types metal Their painting requires compliance with certain nuances.

This type of coating is considered acceptable for covering radiators. Alkyd paint has a number of advantages:

• heat resistance;
• creates a glossy finish on radiators;
• long service life;
• wear resistance;
• high quality.

The main disadvantage of this coating is its unpleasant odor. This is due to the presence of white spirit in alkyd materials.

The smell after applying them to the battery lasts for several days. It may appear for a while when the radiators heat up. Another disadvantage of this material is its long drying time.

Alkyd enamels are produced using on different basis. This could be the basis:

• silicon-organic;
• organic;
• water

Much depends on the color of the colorful product. When choosing a white alkyd enamel, it is recommended to choose a product that contains a titanium-based pigment. Thanks to it, the material will not turn yellow during battery operation.

Acrylic colorful products

Acrylic enamels have advantages over alkyd enamels. They are as follows:

• no odor;
• quick drying period (within 2-3 hours);
• Possibility of application to hot batteries;
• special consistency that simplifies the process of application to the heating device.

Any acrylic paint requires it before applying to the battery preliminary preparation. The surface of the heating device must first be primed and allowed to dry.

The product is applied in several layers. The advantage of the product is its special consistency, reminiscent of sour cream. When painting, the colorful material does not spread.

The surface of the heating device must not be wet. Acrylic enamel does not tolerate moisture.

When applied to the battery, it resembles plastic, which looks organically in the interior of the apartment.

Acrylic enamels have their disadvantages:

• rather short service life and high probability of shedding;
• color change after drying.

Hammer colored products are characterized by one feature - with their help it is possible to obtain several shades from the same color at once. Hammer paints allow you to achieve various texture options on heating devices.

This type of paint material creates a non-uniform coating on radiators. It smoothes out imperfections and uneven surfaces of heating radiators.

Hammer paints are applied to rough surfaces.

To do this, you will need to pre-treat the heating radiator with sandpaper. Otherwise, the products are applied to devices according to the same scheme and rules as other types.

Water-based

It is allowed to paint heating batteries with water-based paints. The main arguments for using this type of paint coating are:

• their resistance to high temperatures;
• quick drying on the surface;
• odorless paint.

The main argument against the use of water-based paint materials is their low wear resistance. According to this criterion, they are significantly inferior to more resistant species.

Powder

Powder coating of radiators has become an alternative to the use of traditional liquid paint materials. The process of applying powder paint to a battery requires compliance with a number of important conditions:

• the dry powder mixture is poured into a special gun and sprayed onto the heating device;
• an electric field arises, attracting colorful particles, where charges of the opposite direction are created;
• The applied paint needs to be polymerized, for which a special oven or heat gun is used.

To ensure high-quality application of such a colorful product on a heating device, in some cases it is required ultraviolet radiation. To create it, you will need an ultraviolet lamp.

Powder paints for radiators undergo three melting stages when applied:

• acquisition of viscous consistency by powder;
• formation of a single layer of melted powder particles;
• The heating device is wetted with the molten polymer.

Silicate colorful products

Products based on silicate resins and aluminum have many advantages:

• high level of adhesion to the surface of the heating device;
• withstand high temperatures significantly exceeding standard values ​​in heating systems;
• plasticity of the material;
• no need to pre-treat the heating device before application.

Silicate paints for radiators are applied to them in a dense layer. In this case, the layer has high plastic properties. When the metal expands due to heating, the silicate base will not crack. When cooled, the product will also retain its plastic properties.

A significant disadvantage of the material is its pungent odor, which requires long-term ventilation of the room. Such products are quite expensive and may not always be available.

Serebryanka

The use of silverfish is quite widespread. It consists of two main components: aluminum powder and varnish. This paint is available in a spray can.

Silver can be applied to primed batteries, as well as over their old coating. This paint product can withstand high temperatures well.

Since silver oxide contains petroleum products, when applied it produces an unpleasant and persistent odor. After treating the radiators, careful and long-term ventilation of the room will be required.

Application methods

Painting radiators consists of several stages:

• preparatory;
• preparing the most colorful material and tools;
• the coloring itself.

At the first stage, you will need to thoroughly rinse the radiator with a solution based on ordinary warm water and detergent. Use a brush to clean all sections of the battery. After washing the device, dry it with napkins.

All radiators need to be degreased before applying paint. The only exceptions are silicate paint materials. The radiator surface is well degreased with alcohol and white spirit solution.

Radiators made of steel and on a base of two metals are additionally processed with sandpaper. Thanks to this, the paint adheres better to the surface of the heating device.

If there is corrosion on the device, it must be treated with a special anti-corrosion compound. It is not necessary to remove all of the old paint. It is enough to wipe off the protruding areas of the old material.

The second stage will require the preparation of basic working tools. These include roller and brushes. Special brushes are used that are intended only for radiators.

Application technology includes the following rules:

• heating off;
• use brushes with soft bristles to avoid large splashes;
• using a regular toothbrush to paint the radiator in hard-to-reach places;
• painting first the internal parts of the device and then moving to its outer side;
• applying paint material from top to bottom to avoid smudges;
• painting the device in 2 layers.

Even if odorless paint is used, it is necessary to carry out work with open windows.

What paint is best to paint radiators?

In Soviet times, we covered traditional cast iron “accordions” MS-140 or steel heating radiators with two types of paints: oil and aluminum (silver). Somewhat later, pentaphthalic enamels PF-115 and the like appeared, and they also came into use. However, the listed coatings “smell” for a long time after application and lose their appearance quite quickly. As a result of almost annual renewal, the paint layer on cast iron batteries during the entire period of operation could reach 3-5 mm.

In the current conditions of a huge selection of various paint and varnish coatings, there are many painting materials intended for heating devices or simply hot surfaces, we will discuss them below. Now let’s list the compounds that are unacceptable to use as paints for radiators:

• oil (MA-25 and others);
• pentaphthalic (PF-115);
• nitrocellulose (NTs-132 and others);
• ordinary aluminum (silver);
• water based paint for interior work.

All types of coatings from this list They share one common drawback - they operate under atmospheric conditions, that is, they are not heat-resistant. If you study the technical characteristics of the same PF-115, it turns out that the temperature range of its operation is from -50 to +60 ºС. It is not surprising that it very soon peels off the battery, whose temperature reaches 80-90 ºС. The same applies to chemically resistant nitrocellulose enamels with a coating that can be exposed to high temperatures.

Therefore, figuring out what paint to paint the battery with is quite simple. It must be heat-resistant, otherwise after a couple of heating seasons the same thing will happen. Below is a list of recommended coatings for batteries:

• alkyd;
• acrylic;
• silicone-aluminum;
• aluminum based on heat-resistant varnishes.

Note. Given types protective coatings are used very widely in various fields for finishing work, so when purchasing you should pay attention to the purpose of the paint. The packaging must indicate that the composition is suitable for coating hot metal surfaces or radiators.

Characteristics of different compositions

Alkyd enamels work normally at temperatures up to 150 ºС, while manufacturers guarantee that light tones of the coating will not turn yellow when heated to 120 ºС. After application, alkyd paint emits an unpleasant odor for some time, which dissipates fairly quickly. When starting up the heating system in the fall, the smell may appear again, but only briefly.

Acrylic paint for heating radiators practically does not smell, the reason is the water base of the composition. It is also the most common due to its affordable cost. The base enamel is snow-white; to change the color, a tinting pigment is added to it. The temperature threshold of coatings is lower than that of alkyd coatings - 80 ºС, but as practice shows, this is enough.

If you want to carry out painting work thoroughly and for a long time, then you can use silicone-aluminum paint for radiators. Its base is silicone resin, while the upper temperature limit approximately 500 ºС. After application, this composition forms a very durable and at the same time plastic layer that calmly perceives the thermal expansion of the metal. Does not require priming and has good adhesion to various surfaces, including from aluminum alloy. Silicone paint has two disadvantages - the presence of an odor that requires long-term weathering after painting, and high cost.

Modern silver is a heat-resistant paint BT-177 that can withstand temperatures up to 200 ºС. Its base is BT-577 varnish, to which aluminum powder is added and mixed thoroughly. It is better to apply this composition to metal over old paint or after priming. The scope of application of BT-177 is most often heating devices located in industrial buildings. The varnish contains petroleum products, so the paint is not odorless; after completing the work, the premises should be ventilated.

It should be noted that enamels for painting radiators are also sold in aerosol cans, which are very convenient to use. This also includes cans of car enamels.

Advice. If you have leftover car enamel in your garage after painting your car, whose expiration date has not expired, then you can safely use it for batteries. The heat resistance of car paints is fine; just remember to what extent the body of a car exposed to the sun gets hot in the summer. True, the smell will also have to disappear.

Before painting batteries, their surfaces must be prepared. First, they are washed from dust and dirt and dried, and then sanded with fine sandpaper. Peeling old paint is removed before treatment.

Advice. On chips of the old coating or in places where it was removed after painting, visible depressions will remain. To prevent this, it is better to clean them, fill them with metal putty and, after drying, sand them, leveling them with the rest of the surface.

The second stage is priming. This is especially important when applying acrylic enamel to bare metal or a layer of putty. The grade of primer is selected to match the metal; you cannot use a primer intended for wood or other materials as a base. After priming, you need to allow the drying time indicated on the packaging.

The last stage is painting. Having covered part of the wall behind the radiator and the floors underneath with film, the coating is applied in 2 layers with a brush, roller or spray gun. The latter method is the most preferable, as it provides penetration into hard-to-reach places.

Advice. It’s better not to paint hot batteries; not all paint is designed for this. And the smell in this case will be stronger, so it is recommended to carry out the work in the off-season.

Conclusion

In terms of availability and color range, acrylic coatings attract the most attention. It is also the only odorless paint for batteries, although it is not the most heat resistant. More durable and resistant compositions will cost more, and after painting work they will require long-term ventilation.

Types of paints

It is wrong to think that a heating radiator can be coated with any paint of high quality or significant cost. Thus, in the past, oil or aluminum paint was often used for heating radiators. Considering them to be the optimal choice for this device, their use was widespread.

Painting radiators using such substances is unacceptable under these conditions, since their function does not involve protecting the metal surface at high temperatures. Thus, the paint on radiators quickly fades, cracks and even peels, requiring re-treatment.

Imperfect options have been replaced by paints more suitable for thermal elements. The best options are the following types of enamel:

• Alkyd. This composition can be used at temperatures no higher than 150 degrees. As the temperature increases, the color gamut does not change in any way. The paint has an unpleasant odor, which disappears after one week after painting. The cost is quite high.

• Acrylic paint for radiators. This is an odorless paint that can withstand approximately 80 degrees. Only available for sale White paint, to which dye is added. The affordable price and availability of a product often puts it in first place.

• Silicone-aluminum. Long-term use can reach five years without re-coating. Range temperature regime reaches 500 degrees. The elasticity and adaptability of the composition to thermal expansion and contraction make the enamel practically invulnerable. The cost of such a substance is quite high, and there is an unpleasant odor that persists for a long time. Such analogues dry quickly.

• Aluminum with heat-resistant varnish. People call this paint silver. Used at a maximum temperature of 200 degrees. It should be applied only to a prepared heating device and it is advisable to use it in non-residential premises. The composition contains many variations of petroleum products, which makes the enamel non-ecological. It smells unpleasant and lasts a long time. The cost is moderate and availability is wide.

The advantages of such paint and varnish coatings in comparison with standard options are obvious. Paint for heating radiators cannot be completely odorless, but there are other positive characteristics.

The above listed compositions are resistant to thermal influences, wear-resistant during operation and do not have a persistent unpleasant odor.

Which paint is better to choose

The aesthetic appearance of the radiator will largely depend not only on the cost of the chosen paint, but also on the compatibility with the material of the radiator itself, as well as the features of its design. What paint to paint? For primary painting, it is better to use glossy options. The paint used for painting repeated type heating radiators is matte - its base will hide all the irregularities and imperfections of the radiator.

Let's look at examples of coloring different types radiators according to their characteristics:

• Paint for cast iron heating radiators has many nuances when painting, which relate to unevenness and not entirely aesthetic joints and seams. In most cases, even matte paint does not hide all the nuances. The only correct solution would be to use colored paint that matches the shade of the interior design of the walls. If there is a need to paint the battery in light colors, then the base of the device is first puttied.

• Aluminum and bimetallic radiators It is better to paint with powder paints, but not white. The downside is that it is almost impossible to process it at home. Firstly, special devices are needed. Secondly, to perform high-quality coloring, you need special skills.

• Spray paints, that is, paints in cans, are the most popular at the present time. This feature is inherent in the fact that the method of applying the product to the surface is the simplest. The main thing is to cover the wall with some material so that it does not get dirty. Often it is necessary to apply at least two coats to even out the surface. It is a quick-drying option.

It is better to seek help from a specialist when choosing paint. The seller will be able to tell you which paint is best to match with a particular type of radiator. It is also necessary to take into account preferences that relate to interior design.

Often, using several types of paint can create a visual combination regarding tone or color. It makes no sense to single out any one section of the battery.

Preparatory work

After the choice of paint for the radiator is made in accordance with the requirements for the composition and functional features product, you can begin the preparatory stage. It consists of the following actions:

1. First, you should treat the surface of the radiator. Secondary painting is usually done, so it is important to accurately assess the condition of the radiator before treatment. If at least five layers of paint have already been applied to the battery, then it is better to remove excess paint using mechanical cleaning.

2. If the previously applied layers are severely damaged, if the paint is cracked or peeling, it must be completely removed to the very base of the metal. For this purpose, special machines or chemical washes are used. This procedure should be performed especially well.

3. In the case where there are no more than three layers, it is enough to treat the surface with sandpaper. It’s worth choosing fine-grained ones. All drips and drops that formed as a result of preliminary staining are preliminarily cut off. The surface must be smooth, without the slightest roughness.

4. After processing with sandpaper, the surface is treated with chemicals that degrease the surface. This can be done using acetone or solvent. Often such work requires several degrees of processing. Only after this is the enamel applied to the surface.

Coloring stages

So that the result does not disappoint and money is not thrown away, it is better to paint the radiator in accordance with a certain technology:

1. Prepare the workplace: cover the floor and cover the wall. Select tools for painting. Only brushes are suitable, sometimes sponges are used. A roller is definitely not suitable for this type of work. The employee must cover his hands with gloves.

2. You should take a little paint onto the brush so that it does not flow over your hands and the handle of the painting device. This way, you can avoid drips on the battery elements and drops on the floor or wall, and the enamel will lie in a more even layer.

3. Painted first inner part batteries. To perform the procedure as efficiently as possible, a sponge is often used. Light wetting movements cover the surface.

4. External part heating element painted secondarily. This is done using a brush of medium thickness. Strokes are made in one direction from left to right or vice versa. It is advisable not to change the direction during the process.

It is better not to apply the paint in a layer that is too thick - it should be thin and more or less uniform. If after drying any defects are visible, then re-painting should be done on the already painted elements. The principle of operation consists of the same steps as applying the first layer of paint.

Most of us grew up in apartments with cast iron radiators or heating registers. In Soviet times, such heating devices were installed “forever”; they were periodically repaired, washed, cleaned and painted with their own hands. There was practically no alternative to such a battery. The need sometimes arises even now.

We welcome the regular reader and offer an article about how to paint heating radiators with your own hands - such a banal, but at the same time difficult type of repair work. All metal radiators and registers require periodic painting.

From the point of view of common sense and to ensure safety, it is mandatory to paint heating devices that are susceptible to corrosion, that is, made of steel and cast iron. But there has long been a tradition that window slopes and window sill niches are painted in White color, radiators also prefer white ones. In any small store, the entire range of heating appliances is painted white, and only in construction hypermarkets can you occasionally see aluminum or colored radiators.

Cast iron

When they talk about painting batteries with their own hands, the first thing that comes to mind is cast iron radiators - reliable, heavy, “eternal.” If you have such radiators in your heating system and are satisfied with the safety of heating your house or apartment, then perhaps you should not change them. If you live in an apartment building, then replacing the heating system may lead to disagreements with the heat supply organization. In a private home, cast iron has its drawbacks, but changing it without reason also makes no sense. But periodic cleaning and painting with your own hands is necessary for cast iron.

Aluminum and bimetallic

You can also paint aluminum and bimetallic heating devices yourself, but this painting is mainly done for aesthetic reasons. To paint aluminum yourself, you need special primers. In bimetal, the steel core is usually not visible, and the aluminum shell is painted.

Copper

Copper batteries oxidize, darken and become less attractive. Therefore, copper radiators and pipes are also painted with your own hands. For copper heating systems, a special primer for non-ferrous metals is used.

Is it possible to paint hot batteries?

Definitely not possible. Paint, even alkyd, will dry very quickly, literally “on the brush.” In the presence of heating, the coating will have many defects: frozen streaks, uneven coloring, thick layer paint, when covering very hot radiators the paint will simply bubble, and during the first wash the heating devices will peel off (or sooner).

If you really, really need to paint hot batteries, you need to turn off the taps and wait until the battery cools down to 30 °C. If the heating season is in full swing and it is impossible to turn it off, it is better to wait until the heating is turned off. There are also special paints for applying to hot surfaces, but how to paint the inside and back with your own hands is a big question. Even special paints for heating appliances should be used in aerosol form - this will ensure uniform application (from the front side).

In any case, painting an undismounted battery with your own hands is practically possible only from the front side, which means it’s easy redecorating heating systems.

Requirements for paintwork

Batteries - a rather atypical element of the interior - are almost always in plain sight, heated to a temperature of 70-90 °C for six months, air convection constantly occurs nearby and brings dust, things are often dried on them.

Therefore, special requirements apply to paint for radiators:

1. Heat resistance. The paint should not swell or peel during operation, that is, during heating. It is very important that the paint looks beautiful for a long time, does not turn yellow or lose color - after all, batteries are often placed in a very visible place under the windows; they play a significant role in the interior.
2. Do not lose color, do not turn yellow, do not peel off under the influence of high temperatures due to heating and at the same time be safe for humans - the coating of heating systems after drying should not release harmful or odorous substances into the room air (the drying process does not count).
3. Good adhesion. The paint should have good adhesion to the surface of the radiator and not peel off during heating or during alternating heating and cooling.
4. The battery coating should create a dense airtight film and prevent corrosion of steel and cast iron radiators. It is also desirable that the paint contains corrosion inhibitors - additives that inhibit oxidation.
5. The coating must be durable and wear-resistant, withstand drying of things and vigorous washing of batteries, including with detergents (non-abrasive!).
6. Sufficient thermal conductivity. The paint should form a fairly thin coating - after all, the thicker the layer, the less heat from the battery is transmitted into the room.

Types of paint

Many years ago, heating systems were painted with oil paints. After a few years they cracked, the batteries were painted with their own hands in the second, third... and subsequent layers. As a result, after 30 years, heating radiators, reliably insulated with a thick layer of paint, practically stopped heating. The modern range of paints for batteries is very large and allows you to cover heating devices with your own hands with a thin, durable coating of a wide variety of colors, while the durability of the coatings can reach 10 years.

A brief description of the various paints is given below.

Acrylic

Acrylic dyes appeared relatively recently. The most common acrylic paints are a water emulsion of particles of acrylic resin and pigment suspended in water. After drying, the acrylic resin merges into one mass, forming a strong wear-resistant layer that firmly holds the pigment.

1. The coating is smooth, uniform and slightly reminiscent of plastic.
2. The bright color of the battery will remain unchanged for 7-8 years, the white will not turn yellow; The paint perfectly withstands elevated temperatures of the heating system, does not crack or peel.
3. After drying, the coating becomes insoluble in water and most solvents and is not afraid of moisture.
4. It is especially worth mentioning that acrylic mixtures on the battery dry in literally half an hour, and there is no sharp odor that irritates the respiratory tract and eyes, like other paints.
5. The good adhesion of acrylic resin allows it to be used for painting both steel and aluminum heating surfaces. There are varieties of acrylic paints based on organic solvents; the quality of the resulting surface of these paints is better than that of alkyd and water-based acrylic paints, and color fastness is also excellent.

Alkyd

Alkyd paints have anti-corrosion properties, good adhesion, elasticity, high heat resistance, and form an even, smooth coating on the battery, which is stronger than acrylic resin.

1. Alkyd compounds dry within 24 hours, the evaporating solvent has a strong unpleasant odor and dissipates within a few more days. After painting the battery, the room must be intensively ventilated. You cannot stay in it - the solvent (especially when the heating is on) is not harmless to humans.
2. Second significant drawback alkyd compositions - low color fastness; after 3-4 years, the white color will begin to turn yellow, and the colored color will begin to lose its brightness. It is better to choose glossy paint - it will preserve the whiteness or brightness of the color on heating appliances longer.

Hammer

This is a modern type of acrylic composition. They form a very durable original coating with an interesting texture. The surface looks as if it was beaten with a small hammer and painted. An uneven, “speckled” surface hides chips in the battery well - this is especially true for rough cast iron.

Other types of paint

To paint radiators with your own hands, they often use silver paint - a suspension of aluminum powder in varnish. Serebryanka forms durable coating, resistant to elevated temperatures and abrasion. It can be applied over primer and over old paint.

Flaws:

• Strong, persistent odor.
• The mixture is explosive and should be used with caution.

In addition, a radiator of a specific “aluminum” type will not fit into every interior.

Compositions based on silicone resins are also used for heating appliances. They form a dense and elastic coating, resistant to abrasion and very high temperatures during heating. Moreover, elasticity does not depend on the aging of the composition. Silicone compounds have high adhesion to any surface and do not require prior priming. These paints also smell very unpleasant when drying.

The most durable elastic coating is formed by polyurethane paints. This paint is a complex suspension of pigments and vinyl chloride copolymers in polyurethane compositions. Polyurethane paint is used to protect heating structures outdoors and in industrial workshops. It has high temperature resistance, high resistance to humidity. For interior work, a two-component paint is used, which forms a beautiful glossy finish.

Epoxy and pentaphthalic enamels are also used for heating devices.

Which one is better to choose?

For a high-tech or perhaps loft-style interior, you can choose silver. For other cases, they are chosen based on the requirements for the radiator: wear resistance, the need to preserve the color longer, and the location of painting.

They are more familiar and reliable, and modern hammer ones generally look very expensive and interesting.

But if you want to decorate the radiator in the nursery or other rooms with your own hands and you don’t plan to dry a mountain of diapers on the radiator, you should try acrylic: it gives a lot of scope for creativity. Acrylic is not chosen because it is not yet very familiar - the very idea that you can paint a battery with your own hands using water-based emulsion is still new. Water-based acrylic also has almost no odor and dries quickly (especially if the heating is on).

The most durable are polyurethane paints and acrylic compositions based on organic solvents.

Advice on choosing the color of a radiator is a very thankless task. We are accustomed to the traditional white color, but in modern interiors, heating devices of the same color as the walls look great, or vice versa - bright, painted with patterns or stylized as a picture, an animal or something else.

The color depends on the taste of the owners and the purpose of the room - in a strict classic living room, white or antique styling would be appropriate, in a nursery you can give free rein to your imagination, in the bathroom and kitchen - a white radiator will have to be washed twice as often as a tinted one in color walls The choice of how to properly paint a radiator with your own hands is yours.

Necessary tools for painting a battery

To paint a heating radiator you will need:

• Brushes with natural bristles - straight and slightly curved.
• Sandpaper.
• Grinder or drill with a wire brush attachment.
• Putty knife.
• Wash.
• Remover remover.
• Primer.
• Metal brush with metal bristles.
• Dye.
• Possibly a spray gun.
• Personal protective equipment - suit, respirator, goggles, gloves.
• Rags.

Preparatory stage

The quality of battery painting primarily depends on surface preparation. Before applying the primer, you must turn off the heating, clean the radiator with your own hands from old paint, dust, dirt and thoroughly degrease. Areas of old paint that are very firmly adhered to the surface and have not peeled off or cracked do not need to be removed.

Methods for removing dust and grease

A used heating radiator must be thoroughly washed and degreased. Treat with warm water; if there are stains of household grease, wash with a good dish soap. Sometimes in hard-to-reach places you can remove dirt with a vacuum cleaner, but it is unlikely to remove stuck dust particles from the battery.

Particular attention to stains of all kinds of technical oils (the battery was in the garage, dripped during transportation) - such stains can only be removed with solvents, white spirit, acetone, gasoline. The surface must be thoroughly dry before applying the primer.

Mechanical removal of old paint coatings

Mechanical removal of old paint - removing paint from a battery manually using sandpaper, a metal brush or using a drill/grinder with special attachments. In some places on the battery it is difficult to reach the paint; cleaning even one radiator with your own hands takes a lot of time and patience, so the chemical method is often used.

Most The best way get rid of old paint on heating appliances - sandblasting. Some heating companies provide just such services.

How to get rid of old paint using chemicals

The chemical method of removing old coating from a heating device makes it quicker and easier to prepare the radiator for priming and painting.

There are a large number of effective types of removers for all types of paints:

• Alkyd.
• Oily ones.
• Perchlorovinyl.
• Bitumen.
• Polyurethane.
• Epoxy.
• Latex and many other compounds.
• For removing powder compounds from metal.
• Universal means.

It should be borne in mind that almost all of these products are not very safe, are often flammable and are not intended for use in a home or apartment. All work on cleaning, priming and painting the battery is best done outside the home - in a garage, shed or under a shed.

If the instructions are followed exactly, these products are relatively safe, but in any case, glasses, gloves and, if necessary, a respirator are required.

When calculating the amount of product per radiator, you should keep in mind that one layer softens 1-2 layers of paint, and if there are a lot of them, then a lot of product will be needed. The area of ​​the cast iron radiator section is 0.244 m².

The battery will have to be processed several times. It is difficult to calculate the surface area of ​​the battery - it makes sense to buy a remover with some reserve.

To soften the paint, a remover is applied to the surface of the radiator and covered with polyethylene. Withstand required quantity time according to the instructions, carefully clean off the paint with a spatula, then with a brush. If there are many layers of paint, the operation will have to be repeated several times.

Then the surface of the battery is treated with the product specified in the instructions, wiped, washed, and dried.

Thermal method

This method uses heat using blowtorch or construction hair dryer. This method practically does not work on metal.

For those who like to experiment, we inform you that sudden heating can lead to a crack in the cast iron battery and “waves” metal sheets from which they are made modern radiators. Yes, and scale stains on the surface of cast iron and steel of a heating device will not please you.

Surface priming rules

Before priming the surface of the heating device, you must carefully remove the paint remover using the product provided in the instructions, wash off dust and scraps of paint and thoroughly dry the radiator. Then the defects are sealed with a special putty and primed. Keep in mind that putty, primer, and each layer of paint reduces the heat transfer of the radiator the next time you turn on the heating.

The strength of adhesion of the paint to the radiator (adhesion) depends on the quality of priming of the battery.

For cast iron and steel, choose a metal product with anti-corrosion additives and suitable as a base for paint.

Do-it-yourself quality dyeing technique

The traditional and time-tested technology for high-quality battery painting involves applying thin layers of paint twice. It should be borne in mind that for most paints, priming the heating elements is a desirable, but optional step.

Don't forget to use personal protective equipment:

• Gloves.
• Points.
• Respirator.
• Thick clothing with long sleeves.

Before painting, clean the radiator from dirt, and then degrease and dry the battery (be sure to do so in that order). Don't forget to turn off the heating first.

General dyeing technology

High-quality painting is always done in two layers. Before applying the second layer, the first layer on the battery must dry. With this order, there will be no unpainted areas, drips, or uneven coloring. Heating radiators are painted either with a brush, or an aerosol, or using a sprayer. There are curved brushes for painting hard-to-reach areas. Painting is done starting from the inside of the battery - this way less paint will get on your hands.

For better coloring, you need to paint one side of the battery, dry it, turn it over, and paint the other. Then the second layer is applied in the same way.

The radiator can only be properly painted when it is removed and the heating is turned off.. If it is impossible to remove, you should clean it, paint the damaged areas with a small brush and paint on the front side with an aerosol can or spray gun.

Painting aluminum radiators

Aluminum batteries (and bimetallic ones) have a non-peeled factory coating with some damage. In this case, it is not necessary to remove it completely; it is enough to clean the damaged areas with your own hands and paint them with aerosol auto enamel.

For aluminum you can use all the paints that are used for ferrous metals. Only the primer must be special - for non-ferrous metals.

Painting copper radiators

Copper darkens over time. Therefore, it is primed with a primer for non-ferrous metals (lead-lead No. 81; urethane; HS-010, GF-032, GF-073, FL-03K, FL-03ZH, VL-02, EP-0126, UR-0116, EF- 094).

To paint the copper surfaces of batteries, the same paints are used as for aluminum, steel, and cast iron.

Copper is often coated with varnish with an aluminum base or simply varnish (VL-51 or ethinol varnish). Water-based acrylic paints are usually not used for heating systems.

Interesting battery color ideas

There are many interesting design ideas for heating radiators. There are two main trends when painting batteries: to match the color of the walls or to make them a bright accent in the design.

Artistic painting

In addition to plain painting, artistic painting of heating devices with acrylic paints (or any other) and decoupage are becoming popular.

There are many options for painting the battery:

• Under animals.
• Pictures from cartoons.
• Bird-flower plants.
• Variations on a rainbow theme.
• Geometric patterns.

Even more vibrant finishing options are provided by decorating batteries using the decoupage technique. With this technique, a drawing is glued onto the surface of the heating device to be decorated with PVA glue - upper layer napkins, rice paper with a pattern. Then the drawing is dried, if necessary, it is completed and covered with transparent varnish. The battery decoupage technique is shown in detail in the video.

Antique painting

Antique batteries are painted in gold, copper or silver with patination in a variety of patterns. A copper heating system coated with varnish or gold varnish looks stylish.

You can decorate heating radiators with your own hands using stucco molding from a self-hardening mass, and then paint them. The mass is produced painted in different colors, including silver, golden, metallic.

And finally, there is a whole series of bulky decorative batteries on legs for retro-style interiors. These heating devices come in the most unimaginable colors and patterns. There will be no need to paint them for the next 15 years - a very durable coating is applied at the factory.

Paint for radiators must meet special requirements, withstand temperatures up to 80-90 ˚С, protect the metal from rusting, and at the same time maintain color. Special paints for metal radiators fully meet these requirements. Other universal paints and enamels have similar properties, but they can withstand temperatures only up to 60˚C. It is worth noting that in many heating systems the batteries practically do not warm up to this temperature. In this article we will talk about what is the best paint to choose for radiators so that it meets all the requirements.

Please note that simple paints and enamels, although used for painting radiators, quite often turn yellow and begin to crack due to high temperatures.

Surface preparation before painting

If the old paint remains intact, has no unevenness, and is laid in no more than three layers, it will be enough to go over the entire surface with fine-grained sandpaper. This will improve the adhesion of the new coat of paint to the surface. After this, the surface is degreased with gasoline or acetone. Everything is thoroughly cleaned again, and they move on to painting.

If the paint layer is old enough and has begun to deteriorate, you first need to clean the heating battery. It is necessary to remove all its layers until only metal remains. This can be done with sandpaper, a drill with a special attachment, or a special remover for fired paint.

After all the old coating has been removed, the remains are cleaned up. A drill with a cord brush is suitable for this. Next, thoroughly degrease the surfaces and cover them with a primer mixture. As a primer for heating systems, it is best to take the GF-021 brand. For the best protection, it is best to use mixtures designed for automobiles. But, by and large, you can use any metal product that has anti-corrosion properties. The batteries begin to be painted after the primer has completely dried.

Selecting paint for radiators - which one is better to paint?

When deciding on paint for radiators, study the label: it should contain the phrase “paint for heating radiators.” The font in some cases may differ; sometimes it can be seen in small letters in the “scope of application” section. If you do not find such a phrase, then it is better not to purchase this product.

Among other things, the manufacturer's name must be on the label. There are often cases when special craftsmen copy the design of well-known brands almost 100%, while seeming to “forget” to indicate the name of the manufacturer. It is better not to pay attention to such enamel for radiators, since, most likely, you will receive a low-quality product, and odorless paint for radiators is out of the question. Batteries painted with this composition will stink for more than one week. There have been cases when it was necessary to remove a layer of such paint using a remover and start all over again, only this time using a quality product.

Matte and glossy paints

Some may wonder what paint to paint radiators with, matte or glossy. In this case, there is no clear answer. All flaws are visible on the glossy surface, and when bright light falls on it, you will clearly see them all. WITH matte finish everything doesn't look so sad.

However, matte enamel loses color over time. This happens because due to the porosity of the layer, dust gets clogged into it. In this regard, experts recommend using white paint for radiators in glossy or semi-gloss tones.

Paint for cast iron radiators

If you decide to cover MS-140 cast iron radiators with glossy paint, then on their surface you will be able to see all the roughness, which, due to the shine, will become even more pronounced. Matt paint will make the batteries grayer. It may seem like there is no way out, but the problem can be solved.

There are several options for solving this problem:

• Choose multi-colored acrylic enamel for radiators. The fact is that white color looks organic only on light or completely white surfaces. But in all other cases, designers advise painting radiators in a shade close to the color of the walls. Therefore, for cast iron radiators you can freely use matte enamel without fear that it will turn gray and lose color. Hammer paint with a textured pattern performed well - after painting, defects on the surface are invisible.
• Of course, there are times when the only solution is white paint for heating radiators. However, be prepared for the fact that radiators will require repainting after about 2-3 years.
• Alternatively, defects in the surface of radiators can be pre-leveled with putty - polyester for cars or epoxy. Before puttying, the surface is degreased and primed. Then the radiator is sanded, dust removed with a dry cloth and painted. With this approach, both glossy and semi-gloss shades of paint will look equally beautiful. However, be prepared for a lot of hard work. Although the end result will please you.

Thanks to the presented options, you can more freely approach the choice of suitable paint for heating radiators.

Types of paints for batteries

Painting compositions for heating radiators can be acrylic, alkyd, as well as their variants on various bases.

Alkyd enamel

Alkyd enamel for heating radiators is available in a wide range of colors. Although it has a slight odor, it dissipates quickly. In addition, such dyes are characterized by color fastness.

Depending on the basis there are:

• Solvent based alkyd enamel for radiators. This enamel has a very strong pungent odor, although the surface is beautiful and glossy. The most commonly purchased enamel is PF-115. Sometimes they choose Pesto enamel - its disadvantage is that it requires tinting with blue pigment to avoid yellowing.
• Silicone enamel turns matte. As a rule, this group contains heat-resistant paints with a temperature threshold of up to 600 ℃. Sometimes they produce aerosol paints for heating radiators from this category - they are much easier to apply.
• Water-based paint for radiators. These paints vary in their area of ​​application. In particular, heat-resistant types of enamel are used for radiators so that they do not darken over time. In white enamel, titanium pigment is desirable. The main guideline when choosing quality paint is its price.

Acrylic paints

The surface texture of dried acrylic enamel is similar to plastic, both in visual and tactile sensations. The advantages of acrylic paint for heating radiators are that it adheres well to the surface and is easy to clean. Some varieties of such enamel are practically odorless because they are water-based. However, you need to choose acrylic paint for batteries that is resistant to heat.

For these purposes, you can purchase VD-AK-1179 paint. True, it requires preliminary priming of the surface to be painted. This enamel dries for 2 hours between layers and 24 hours completely.

Another type of acrylic enamel for heating radiators is “Thermakrill” from the company ALP ENAMEL. This paint has a specific smell, however, it contains anti-corrosion additives. Can withstand temperatures up to 120℃, can be used for any metal surfaces, particularly low carbon and of stainless steel, titanium and aluminum alloys, protects them from oxidation. Has a wide palette of shades. Partial drying for repainting occurs after 20-30 minutes at 20 ℃, and the paint will dry completely after 2 days.

There are a lot of options for acrylic enamels, so everyone can choose a paint to suit their taste.

Oil based paint

Since such compositions quickly lose their original appearance - the color changes, the shine disappears, cracks appear - they are almost never used for painting heating appliances.

Hammer enamel

Hammer paint for painting radiators is a type of alkyd enamel that allows you to create textured surface and mask defects only with paint. Various pigments can create a hammered texture, the effect of hammer blows and other interesting solutions.

Before painting, the surface is prepared in the usual way - cleaned, sanded, primed, degreased. If the working surface is smooth, it is sanded to obtain small irregularities.

Powder dyes

With the help of such dyes, steel, bimetallic and aluminum batteries are painted under production conditions. For home painting, it is used very rarely due to the need for a special tool - a spray gun. Although some services rent out such equipment.

According to the technology, a negative charge is transferred to the cleaned part, and powder paint– positive. To do this, you need a diesel generator that produces current at a voltage of 25-30 kV with a power of a fraction of an ampere.

The potential difference allows the powder to be evenly sprayed over the entire surface to be painted. On next stage The dye is polymerized to make it hard. It is performed by heating the product to a certain temperature. Its range is from 170-200℃ to 350℃.

The lower temperature threshold can be created with a heat gun, but to pump up high temperatures you will need a furnace that will gradually warm up the product. Alternatively, you can use paint that polymerizes under the influence of ultraviolet light. Then in a closed room it is enough to turn on a special lamp for a specified time.

Be that as it may, such technology is difficult to implement at home. You may be able to have your radiator painted in an equipped auto repair shop.

Thus, from all the options for paints for radiators, everyone can choose the most suitable and most affordable one. Even if it is Oil paint– this is not a relevant choice, but it has a right to exist.

Radiator paints without odor

There is a separate category of paints and varnishes - odorless dispersion acrylic paint for radiators. And although it cannot be said that it has no smell at all, it is not sharp and is almost invisible. Please note that you need to purchase paint specially designed for radiators, designed for use at high temperatures - the manufacturer indicates these indicators on the label.

It is worth noting that the odorless paint for batteries is quick-drying, easy to apply and lays down in an even layer, does not lose color or crack. You can choose from semi-gloss and gloss shades.

Before painting the surface with water-based paints, it must be primed so that rust does not seep through the pigment.

In addition, you can purchase Element paints from Eskaro, Aqua-Heizkorperlack from Dufa, as well as odorless materials from Triora, Thermo, Dufa Retail and others.

Radiator paint thinner

Of course, the new one will fit tightly and evenly only if the old coating from the radiators is completely removed. In order not to waste time scraping the metal by hand or stripping it with a drill and brush, you can use special gel removers. This composition is applied to the surface of the radiator and left for a certain time. When the paint softens, simply scrape it off with a spatula.

You can apply paint remover with an old brush with natural bristles or a metal or wooden spatula. Among various options There are aerosol types of washes. In order not to damage neighboring surfaces, before spraying the composition, cover all nearby objects with film.

Manufacturers indicate the exposure time for various compositions on the packaging. After a specified period, the old coating becomes soft enough that it can be removed without difficulty.

Although the remover contains chemically active components, they do not damage metal and wooden objects, as well as skin. But it is still better to use gloves when working. Residues from the radiator can be washed off with plain water.

Such brands of remover as B-52 or SP-6 performed well. Domestic and foreign manufacturers produce many analogues of such substances, varying in price and depth of penetration.

conclusions

As it became clear, the range of types and colors of dyes for radiators is very extensive. When purchasing, you will need to choose the color and type of paint - matte, semi-gloss or gloss. In addition, it is important to decide what kind of paint you want to buy - alkyd enamel or acrylic. The last step is to select a manufacturer.

Preparatory activities for heating season begin with inspecting and checking the condition of batteries, pipes, taps and all coupling connections. If there are no problems and all elements of the battery fittings are in order, you can proceed to cleaning and, if necessary, painting the heating radiators. In the old days, steel radiators and cast iron radiators were painted with whatever was in the store. Today, the range and choice of paint and varnish materials is simply huge, so deciding what paint to paint radiators with is not as easy as it might seem. But we know one thing for sure, it should be odorless paint.

How to choose the right coating for radiators

Any specialist involved in the repair of pipes and radiators, when asked what paint is best to paint heating radiators, will answer:

• The paint coating must be thin and with maximum thermal conductivity of the paint layer in order to ensure good heat transfer to the room air;
• The paint must provide protection to the metal surface;
• The coating must withstand heating temperatures of up to 150 o C for high-pressure radiators and 120-130 o C for conventional steel or cast iron batteries.

For your information! Paint for cast iron radiators, in addition to all the above conditions, must have high fluidity and low viscosity.

Even after priming, the cast iron surface remains quite rough and porous, so for cast iron best choice There will be aerosol forms. The radiator is painted in several passes, each layer must be thoroughly dried and any stains removed. Generally, heat resistant battery spray paint has a very low odor, but paint installed radiators necessary only with open windows, in dry, warm weather.

For conventional steel and aluminum heating radiators, the use of aerosols allows you to apply a thin layer to the most hidden places where it is difficult to reach with a brush or roller. In addition, a thin layer of enamel dries 2-3 times faster, which means that even if there is a slight odor, it will disappear in half an hour. The smell from a thick layer of enamel on an organic solvent will stay on the radiator for 5-6 hours, for oil or pentaphthalic paint - for several days.

Heat resistance and volatility of paint for heating appliances

First of all, it should be noted that odorless paint for heating radiators does not exist in nature. Any enamel has a slight but pronounced odor. Even paints for heating appliances, interior wall decoration based on acrylic polymers, or simply water-based brands also have an odor.

Ask a store clerk or building materials showroom for odorless radiator paint, and he will give you a whole list of heat-resistant enamels with the word “odorless” on the label. Actually this is not true. If you take the most seemingly safe water-based paint and paint a heating radiator at a temperature of 30-45 o C, the smell will be quite unpleasant.

Imported, for example, Polish, Czech or German paints for interior work and heating radiators may have virtually no odor or have a slight pleasant aroma, for example, fresh ice cream or sawn wood. But this does not mean that such odorless radiator paint is absolutely safe and cannot affect your well-being.

The production technology allows us to skillfully mask the real smell of paint, therefore a special index of volatile content is used in imported paints and varnishes organic compounds, or in the abbreviated version - VOC. Instead of a vague concept of odor, VOC precisely defines the maximum content of volatile organic compounds that will have to be inhaled when painting a heating radiator. Even for safe, and practically odorless, acrylic enamel for heating elements, the standard allows no more than 130 g of organic volatile substances per liter of material.

The easiest way is to determine the heat resistance of the paint and varnish material. The label of a can of enamel for heating systems always indicates Maximum temperature radiator at which the coating can be applied, and the upper limit of battery heating. For central heating systems, the coolant temperature rarely exceeds 100 o C, but in private houses some of the pipes draining hot water from the boiler heat exchanger, can heat up to 120-130 o C.

Paint options for heating systems

The range of modern paints for heating systems is very large. In order to understand the advantages and disadvantages of each paint separately, you will need special knowledge and a large amount of free time. In a simplified form, all paints for radiators and heating pipes can be divided into four groups:

• Alkyd paints and varnishes;
• Acrylic heat-resistant coatings;
• Painting materials based on silicone polymers.

For your information! Often, when selecting a suitable paint and varnish material, the question arises whether it is possible to paint the battery with water-based paint.

If you ask a specialist a similar question, whether it is possible to paint batteries with acrylic paint, he will probably answer in the affirmative, but with the caveat that it can only be painted with a brand specially designed for heating systems. You cannot paint the metal of batteries or heating radiators with ordinary water-based paint, even if there is no smell. The composition of the water-emulsion mass includes salt emulsion stabilizers and surfactants that provoke metal corrosion. An attempt to paint the bare metal of batteries will inevitably lead to the formation of microbubbles with an oxidized surface, which also intensifies the already not very pleasant smell.

Acrylic paints and varnishes for radiators

The main difference between acrylic paint for radiators and conventional water-based paint is the presence of a special inhibitor that prevents instant rusting of pure metal in an aqueous environment.

Acrylic resins have low resistance to heat, so special color stabilizers are used for materials intended for use in heating systems. This acrylic paint has good hiding power, density, does not lose whiteness during the warranty period and, of course, is practically odorless. More precisely, there is a smell, but it is the smell of a flavoring agent. Such coatings are applied to the necessarily primed surface of the heating radiator using a brush or spray.

After drying, a very even layer with a semi-matte surface is formed on the pipes and radiators.

Alkyd materials

Alkyd enamels are used less for aluminum radiators and are more often used for steel and cast iron batteries. Alkyd paints and varnishes can withstand temperatures up to 150-170 o C, so metal pipes are coated with similar paint steam heating and systems in which high-boiling antifreeze or antifreeze is used instead of water. The smell of alkyd enamels is much richer and more toxic due to the high content of polar hydrocarbon solvents. Imported samples and the best domestic brands for heating systems may exhibit an odor only during the first hours of radiator heating.

The density and adhesion of alkyd varnishes is much higher than that of acrylic resins. Therefore, despite the smell, they are used to paint old cast iron and steel batteries, in which there is a possibility of fistulas and leaks at the connections.

Silicone and organosilicon paints

Paints and varnishes based on silicone or silicone are rarely used for painting water heating radiators. The silicone coating has a high temperature of decomposition and peeling of paint, and is not afraid of moisture and sudden temperature changes. This coating has a very weak but unpleasant odor, which is difficult to evaporate from the room. Unlike alkyd enamels, silicone, despite the smell, is safer. After drying, the smell does not appear even with very high heat.

The disadvantages of silicone paints for heating radiators include low thermal conductivity. Even a relatively thin layer creates significant thermal resistance, so metal micron powders of aluminum, nickel, oxidized copper and bronze can be added to the paint.

How to paint a heating radiator

How thinner layer paint, the better the heat transfer, therefore, before applying a fresh layer of paint, you need to find a way to remove old paint from radiators. This will increase heat transfer and improve the adhesion of the new layer to the metal or primer.

Traditionally, three methods are used to remove old coating:

The paint is fired using a hair dryer. When heated, the old layer softens and is easily separated from the base metal. After firing, finishing scraping and brushing will be required.

Chemical methods are rarely used due to the high chemical activity of the reagent. The old paint is coated with a gel-like mass of thickened orthophosphoric acid, and after half an hour the coating can be removed with a spatula. If it is not possible to remove the old coating, then you should remove at least the surface layer to a thickness of 0.1-0.5 mm with sandpaper.

Conclusion

In any case, the cleaned battery must be degreased and primed, only after which acrylic or alkyd enamel can be applied. The best painting option is considered complete disassembly body, but such methods are resorted to only when major renovation or replacing the heating system.
