Applying paintwork at subzero temperatures. Paints for working in winter from the manufacturer NPP Hz At what temperature can you paint with varnish?
I went to a seminar organized by the Publishing House “Origami” magazine “Cleaning. Painting”, held in St. Petersburg on November 14-15, 2011 under the title “Practice of applying paint and varnish coatings during negative temperatures”.
In addition to listening to information that was well known to me about the types of corrosion and how to deal with it, about Wiwa painting equipment, which I will talk about later in the Equipment section, where I have already described my experience with many painting machines, and showed a small master class on staining corrugated sheets.
I also listened to a very interesting lecture by technologists from the Morozov Chemical Plant about applying paint at subzero temperatures.
Morozov Chemical Plant is the oldest Russian enamels production enterprise. It was he who began producing heat-resistant enamels of the well-known types KO and OS. I will also talk about enamels, but later, in the Materials section. I think it will be interesting.
I had a long-standing correspondence relationship with MHZ. 
It was very nice to meet you in real life. In their professional approach to AKZ, no doubt. Just look at the trips of the chief technologist of the MHZ Urvantseva G. to many objects where they are painted with enamels, her constant consultations and technical supervision of the painting production at the objects. A huge number of grateful reviews about MHZ.
So, returning to the main topic of the seminar.
Paints can be applied at sub-zero temperatures. To do this, the following conditions must be met:
1) You cannot paint at a temperature of +-5 degrees. C. This is due to the formation of condensation, dew, on the metal surface. In general, this temperature is the worst for painting with any paints.
2) The surface to be painted and the paint must be at the same temperature. When airless spraying warm paint onto a cold surface, condensation also forms when materials of two different temperatures come into contact. Even if we all understand that painting using the airless method occurs very quickly, condensation nevertheless forms.
3) The question of how to paint concrete surfaces at subzero temperatures requires additional consideration.
Of course, a lot has been said about the fact that it is possible to paint with OS and KO enamels produced by MHZ, down to -10 degrees C, without loss of quality, but I did not have to work with them at such a temperature.
I had to work with enamels:
PF-115 and ХВ-0278, at temperatures from -0 to -10 degrees. S. It was simply cold to work further. I painted it in a cold room, using paint that was stored there.
HB -174 in the open air at a temperature of 0. + 5 degrees C. Metal structures of the same temperature, paint stored at the same temperature.
PF-100 in a room at a temperature of -5, + 7 degrees C, which was eventually raised to +12 degrees C
As you can see, the temperature regime was not observed everywhere.
As a result:
Application:- the same as always.
Drying:ХВ 0278, 2-3 hours (same as always)
PF-100 - drying 2-3 days (according to the passport - a day)
PF – 115 drying from 7-10 days or more (according to the passport – a day)
ХВ -174, same as always, drying time 2-3 hours.
Polymerization:ХВ 0278, 5-7 days (same as always).
PF-100, 5 days.
PF – 115, not known. When we left the site, it was not yet dry :)
HB -174, drying 2-3 hours (same as always).
Exploitation: XB 0278 has been standing for more than a year, without any coating defects.
PF-100, negative reviews no, it is impossible to enter the painting area
PF - 115, stood for half a year, in the fall it began to fly off like burdocks.
ХВ -174, stood for a year. It started flying off like burdocks.
It is worth noting that enamels PF-100 and XB-0278 are classified as primer enamels for rust. They have additional additives in their formula and have an order of magnitude different cost. Although I am skeptical about coatings such as primer-enamel for rust, nevertheless, in these conditions they showed the best results.
PF-115, based on Russian SNIP, is not recommended for painting metal structures used in industrial environments. Therefore, the legality of the project for painting PF-115 and metal structures is in great doubt. Even if the application conditions were met at subzero temperatures, it behaved in the most odorous manner.
An example of painting XB-174, which in its plastic properties does not differ from XB-0278, showed non-compliance with technology and the result was not long in coming.
Thus, on personal practical experience from my observations, I can confirm, high-quality coating It can be done at sub-zero temperatures. The main thing is not to carry out painting work at + – 5 degrees. WITH.
The recommended temperature threshold for painting work should not be less than +5 degrees C. If objective reasons there is an urgent need to varnish the floor at sub-zero temperatures, it is worth paying close attention preliminary preparation surfaces.
In addition to the fact that any floor must be cleared of traces of old coating, sanded, washed and dried, there are additional recommendations for preparation various materials varnished surface at temperatures below 0 C:
- It is advisable to paint or varnish concrete floors no earlier than a year after creation, so that the surface is “free of dust.” Without preliminary exposure it is possible to carry out painting work on bulk concrete floors in workshops, hangars, warehouses;
- Pre-free the metal floor from moisture or ice and treat it with a torch (petrol or gas);
- It is extremely undesirable to varnish a wooden floor at subzero temperatures due to frozen moisture particles in the porous structure of the wood - the surface is unevenly protected by paintwork. You can make sure that the base does not contain excess moisture using a piece of tape glued to the floor surface for a day. If no condensation appears on the tape during this time, varnishing and painting can be carried out.
What sub-zero temperatures can wood varnish withstand?
Modern paint and varnish manufacturers, through additional inclusions, have ensured that their products can withstand short-term sub-zero temperatures. However, temperatures below -5 C are harmful for products coated with wood varnish.
Experienced builders advise covering the indoor floor with varnish for outdoor use, which can withstand lower temperatures, but there are pitfalls here too. If a lot of traffic is planned in the room, i.e. there will be a load on the surface, the varnish for external use will undergo very rapid abrasion and become covered with “tracks”.
What else is worth thinking about when carrying out paintwork at low temperatures?
For a high-quality result, namely for a perfectly varnished surface, you need to remember such nuances as:
- Quality tools. Perfect wood varnish brush– wide and flat. The bristles can be either natural or artificial. The basic rule is that artificial pile should not be painted, otherwise the surface will acquire a dirty tint with streaks;
- Rationally selected varnish. To ensure that the result meets your expectations, carefully study all offers from paint and varnish manufacturers. Do not hesitate to seek help from specialists from construction stores or online markets: one “missed” question threatens to have a less than impressive effect from the work done.
- Varnish applied at subzero temperatures takes 3 times longer to dry. In such cases, professionals recommend applying paint and varnish cover the object with scaffolding and film and provide it with a thermal gun.
Before deciding on such a desperate act as varnishing the floor when sub-zero temperatures, repeatedly weigh the pros and cons. The formation of condensate, which negatively affects adhesion, is inevitable under such conditions. This means that such a coating will not differ in durability.
Are there façade paints that can be applied at sub-zero temperatures?
Facade paints that can be applied at sub-zero temperatures are called all-season (or winter) paints.
All-season acrylic frost-resistant paint Akrial-Lux designed specifically for harsh climatic conditions, including areas with sudden changes in weather conditions. Winter paint is used for painting facades made of concrete, foam concrete, asbestos cement in all climatic zones, in industrial centers with increased air pollution.
All-season winter paint for facade works Akrial-Lux It is highly resistant to ultraviolet radiation and weathering, and forms a durable, vapor-permeable coating. Has excellent adhesion to concrete, foam concrete, asbestos cement, brick, plaster.
Is it possible to paint the facade of a wooden house in rainy or cold weather?
It fits well on surfaces previously painted with oil, alkyd, latex and other paints (with the exception of lime paints).
All-season winter paint Akrial-Lux applied to the surface with a brush, roller or spray gun in 1-2 layers. Painting work should be carried out at an air temperature of at least -20ºС, provided that the surface to be treated is dry and not icy. Winter paint significantly increases the moisture resistance, weather resistance and service life of the facade.
Special restoration paint is used to restore and restore building facades. Façade. This special paint is recommended for use in particularly responsible and construction restoration work on the most complex objects.
The paint can be used at any time of the year at temperatures from -20°C to +35°C.

More information about facade acrylic paints (winter paint, all-season paint, choice of facade paint) can be found on our website. We hope the sections of the site will help you choose optimal solution for finishing your facade.
Return to list of questions
print version
The main part of painting work is carried out at positive temperatures, the lowest recommended threshold is +5 C. However, sometimes there is an urgent need to paint, for example, the facade of a building, in negative temperatures. This may be associated both with updating the appearance of the building and with the delivery of the facility on time.
How does façade paint behave at sub-zero temperatures?
In addition, there are also objective production reasons for this work at temperatures below 0 C.
Rules and recommendations for painting surfaces at sub-zero temperatures
Compliance with the general principles of painting technology implies careful preparation of the surface for painting. Everything is thoroughly cleaned of traces of old paint, treated with sandpaper, putty is applied to all irregularities, and if necessary, covered with a primer. So, before painting, the wall or surface to be painted must be clean and dry.
- metal painting
If we are going to paint metal, then there should be no condensation or ice on it. Mechanical cleaning of the surface will not work; a thin layer, invisible to the eye, will still remain. Therefore, in addition to removing microparticles of moisture, it is recommended to treat the surface with a torch of a gas or gasoline burner.
- wood coloring
It is strictly not recommended to paint wood in the cold season.
This is due to the fact that there is always a certain percentage of moisture between the wood fibers. At negative values, the water between the fibers turns into ice and the surface is not fully saturated with paintwork materials. If an emergency does arise, stick a 5*5 cm piece of tape on a wooden surface and, if condensation does not appear on the tape after a day, then such a surface is more or less suitable for painting. Thus, when painting wood, you must make sure that the base does not contain frozen water.
- concrete painting
Concrete, like wood, has a porous structure. Besides, concrete structures exposed to weathering in outdoor conditions. Another feature of concrete is that it is advisable to paint it no earlier than 1 year after installation. This is due to its hygroscopicity and the need for dust removal. Basically, self-leveling concrete floors in hangars, workshops and warehouses handed over to the customer are painted in negative temperatures without preliminary exposure.
- painting bricks and plastered surfaces
Applicable general technology surface preparation before painting.
In this borderline state, condensation forms on the surface to be painted, especially metal. The value of painting for condensation, even if unnoticeable, will impair adhesion and significantly reduce polymer properties the paint used. In the future, this will certainly affect the quality and durability of the entire coating.
When painting objects in conditions of negative temperatures, be sure to keep in mind that the drying time of paintwork materials can be 2-3 times longer than the same period of painting at positive outside temperatures. Therefore, after applying paint and varnish to the surface, it is advisable to overlap the object scaffolding with film and provide an additional thermal gun.
The choice of paint must be taken very seriously. The final result of the work—the durability and quality of the resulting protective coating—depends on your choice.
Paints that are used at subzero temperatures
Universal(wood, concrete, plaster, brick)
Tikkurila Euro Facade(up to -20 C)
Forms a high-quality weather-resistant coating. For the first layer, the paint is diluted with Euro Facade thinner in an amount of 10-20% of the total mass. For the final coating, the paint is applied without dilution. After drying it becomes durable matte finish. When used, the temperature of the applied paint must be at least +10 C. Consumption 1l./6m2.
Metal
Miranol is a thixotropic (jelly-like) high-gloss alkyd enamel, diluted up to 30% by volume. Good light and weather resistance. Consumption 1l/12-14m2.
Pansarimaali- excellent alkyd semi-gloss paint with active anti-corrosion properties. Mainly used for painting roofs, gutter pipes, railings and similar metal structures. At negative temperatures it needs to be diluted with up to 30% solvent. Consumption 1l/8-12m2.
Garden- semi-matte alkyd enamel with excellent wear-resistant characteristics. When working below 0 C, it needs to be diluted with solvents up to 30% by volume. Consumption 1l/8-12m2.
So, thanks to modern paints and varnishes, the ability to paint any surface at subzero temperatures has become possible.

Benefits of anti-rust paint
IN repair work We are often faced with the need to paint metal pipes and metal structures, as well as other metal products. Big problem The point here is that often the metal oxidizes in the presence of moisture and rusts. To remove rust from metal, you need to mechanical cleaning, then anti-corrosion treatment and painting. This is a very troublesome undertaking; often structural parts are inaccessible for rust removal.
Finally, to make this process easier, rust paints were created, they are also very beautiful as decorative coating. These are modern broad-spectrum paints.
Advantages of this type of paint:
- applied directly to the rusty surface
- creates a coating on the metal that repels water and dirt
- covers the base well
- powerful grip on the base
- anti-corrosion
- quick drying
- the coating is durable, up to 8 years
- wealth of colors
Disadvantages of this type of paint:
- You cannot paint objects with it that heat up to more than 150 degrees Celsius.
- Items painted with this paint must not come into contact with drinking water
Types of paints for rust
To achieve the desired effect when processing with these paints, you need to understand their types and areas of applicability. Rust paints are classified according to the main substance, purpose and maximum temperature use, number of components. So, there are water-based paints with phosphoric acid, they are the cheapest, but they have low resistance to environment; There are two-component ones with additives epoxy resins, polyurethane, and corrosion inhibitors. Based on the main substance, paints are divided into:
- Epoxy. Toxic, do not use in everyday life. Suitable for highly heated metal structures.
- Oily. Contains drying oil and natural oils. Not resistant to temperature. Anti-corrosion protection outdoors is low, suitable indoors.
- Alkyd. For galvanized metal. Extremely flammable, cannot be used for highly heated metal structures. Very adhesive.
- Acrylic. Long-lasting anti-corrosion protection. Suitable for highly heated structures, such as heating elements, indoors and outdoors.
- Special anti-rust paint 3 in 1. Reduces the cost and shortens the restoration of rusted metal. Quickly applies directly to bare metal. Low cost. Includes resins, anti-corrosion elements. Highly adhesive, dries quickly, protects for up to 8 years.
- Hammer paints. Gives a rough finish with a metallic sheen, similar to a hammer.
The paint uses alkyds, acrylics, epoxies, and aluminum powder. Also produces glossy and semi-matte shades. Suitable also for non-ferrous metals. There is no need to apply a primer before application. The first layer acts as a primer, the second is anti-corrosion, the third acts as the enamel itself. You cannot paint objects heated above 150 degrees.
- Anti-corrosion paints for car body repairs.
- Aerosol form. It has many functions, convenient for touching up paint defects and difficult to access areas. Also suitable for non-ferrous metals and other natural materials. The universal grade of this paint also functions as a primer, anti-corrosion and decorative.
Methods for protecting metal from rust:
- Active electrochemical protection
- Galvanic tread protection
- Cold galvanizing matella
- Capping rust in a polymer film, painting metal
- Phosphating, rust conversion
Anti-rust paint for exterior use
Metal structures where anti-corrosion painting is necessary:
- water supply and heating pipes
- metal fencing
- architectural metal structures
- greenhouses
- bars, gates
Applying anti-rust paint to the surface
To achieve the expected effect during repair, you must correctly follow the stages of processing the item with these paints. You need to carefully follow the sequence of actions, otherwise your work may turn out to be defective.
- Paint heating systems only when they are turned off; use heat-resistant paint that can withstand up to 150 degrees.
- Stoves are painted with compounds that can withstand temperatures up to 500 degrees.
- Non-ferrous metals require special primers.
- At facilities for open air organic solvents are needed.
- If the rust is loose, it must be removed first, otherwise the paint will crumble.
- Before using the paint, check that its heat resistance corresponds to the heating temperature of the product being painted.
The best paint for rust
The price depends on the company and the components.
Let us pay attention only to the most widely used types of paints, high quality which have been proven in practice.
Hammerite for rust:
Most popular. With its help you can achieve gloss, hammer and slightly matte effects. Prevents dirt from accumulating on the structure. Used in the design of cottages, in industrial construction, in roofing works, in painting communications, industrial and agricultural equipment, various metal structures. The surface does not need to be cleaned.
PromAlpForum
Withstands temperatures from -20 to + 80 degrees. The paint simultaneously acts as a primer, rust converter and decorative coating. Dries quickly, several layers can be applied in a day. It is necessary to ensure that the surface does not peel off before painting. Cannot be used together with bituminous materials. Non-ferrous metals must be pre-primed.
Primers-enamels for rust:
They are very convenient to use and really facilitate the process of removing rust when applied. They give a 3 in 1 effect, i.e. act simultaneously as a primer, anti-corrosion agent and decorative coating. The surface is cleaned of dirt, degreased with white spirit, and rust is removed using a spatula, metal brush or emery cloth. Mix and apply two layers with an interval of 30 minutes to 5 hours. If this time has expired, painting with a second coat can only be done after 30 days.
Other popular most purchased rust paints:
- Enamel primer “Rzhavoed-Universal. Cleans and primes the base. Filled color is created with a second layer.
- Stainless steel paint. Alkyd-based, quick-drying, anti-corrosion.
- Iron lead paint. A good one fits, masks flaws. Does not have a strong anti-rust effect. Low price.
- Primer enamel Alpina (Direct auf Rost). There is no lead, unlike many other paints. Doesn't smell, creates durable coating, fits well. First, it is enough to remove dirt from the metal.
In general, when using rust paint, it is important to read its instructions carefully because there can be significant differences in application different varieties these colors. At the same time, it is necessary to pay attention that in some instructions the quality of the paint is somewhat overestimated, so it is necessary to check in other sources whether it is actually necessary to prime the surface before use, as well as such indicators as, for example, the suitability of the paint at - 20 degrees frost, are written only for force majeure circumstances, but in reality this does not mean that it is usually used at such a temperature.
Typically, painting work is planned for the warm season, when the temperature conditions are most favorable for this. The lower recommended temperature threshold for painting is plus 5 degrees. But now there are many modern paints and primers that are suitable even for negative temperatures. In this regard, the minimum possible limit at what temperature you can paint outdoors has changed.
Features of painting work in winter
In industrial conditions, the need for painting at low temperatures arises if the object needs to be delivered on time, or if there is an urgent need to renew the surface of the building. In everyday life, such urgency is rarely observed, but it still happens. There are a number of features of painting in the cold season:
- The most unfavorable temperature for using paints, enamels and primers in winter is from minus 5 degrees to plus 5 degrees. It’s better to work even in cold weather, because it is in the specified range that condensation will form on any surface. In the presence of moisture, the adhesion of the coating greatly deteriorates and the properties of the paints change. The quality of the coating decreases and it will not last long.
- If you decide to paint facades in cold weather, you need to remember that facade paint of any brand takes 2-3 times longer to dry than in warm weather. To get a high-quality coating, you need to use a heat gun for drying or stretch the film over scaffolding.
- You should choose only the one that is suitable for winter season enamel, primer. Using the wrong material will cause it to freeze, and the ice will prevent the product from being applied to the walls. The final result of the work depends on the quality of the paint.
A number of modern paints are perfectly applied at zero temperatures and in frost, some can be used down to –20 degrees. There are good products that are resistant to temperature changes. It is important that the temperature of the paint and varnish material itself be positive during operation. If the material is cold, it is placed in a container in a bucket of warm water.
The rules for using primer and paint in cold air mention mandatory training surfaces. You cannot use coloring materials without certain actions:
- clean the work area from old coating;
- treat the surface with a sandblasting machine, sandpaper or other convenient method;
- fill in uneven spots with putty;
- if the technology requires, apply priming (the walls need to be primed if this is indicated by the manufacturer on the paint packaging).
You cannot work if it is raining or snowing - you need to wait for normal weather to arrive. Painting should be done with a roller or brush, but it’s better to forget about the spray gun - its nozzle will quickly become clogged.
The most important thing is to make the surface clean and dry. You should also bring the enamel to the desired viscosity. Usually water-based paints are used, which are diluted with water. It is necessary to remember that alkyd materials sharply increase their viscosity in the cold, and do not forget to dilute and warm them up in time.
Primer work
In winter, use a primer that is resistant to low temperatures (frost-resistant primer). If iron is stained, special phosphating compounds are used. They can be applied over rust, as they include special anti-corrosion components. Priming provides additional protection against corrosion and increases the adhesion of the final coating.
Painting house facades
Carrying out external facade work in winter is possible if you choose the right paint. After cleaning the walls from dirt and dust, they sand them; if there are areas of old paint or mold, they are removed. Next, prime the walls with a product of the same brand as the base paint - this will improve the quality of the coating. They work with packages brought from warm places. As soon as the material begins to freeze, it is put into a warm place and another package is taken out. The second coat of paint is usually applied after 3-5 days.
Painting brick and plastered surfaces
The painting of such surfaces is no different from that of the facades of the house. It is only important not to paint immediately after finishing the masonry - the work is postponed, the minimum period is a year. If you paint right away, the coating will peel off. Surface preparation is required (cleaning with a brush to remove dirt, dust, mold). The chipped plaster is cleaned, the holes are sealed, and allowed to dry thoroughly. You can also fill deep holes with frost-resistant silicone sealant. After priming, the wall is allowed to dry for 5–7 days, then it is painted with a roller or brush.
Concrete processing
Concrete floors and walls have a porous surface. Also outer side Concrete products weather faster and the coating dye loses its brightness. Painting concrete can be done a year after installation, this is necessary so that some of the concrete dust evaporates. In some cases, it is possible to paint surfaces without exposure - for example, in a workshop, warehouse, hangar.
Metal processing
In winter, you may need to paint pipes, garage walls, iron cladding of sheds, corrugated sheet fences, etc. Metal does not absorb moisture, so it does not change properties depending on the climate. For painting work, special metal compositions should be used - at sub-zero temperatures they form a strong elastic film.
Tips for painting metal in winter:
- the surface must be dry, clean, free of rust using abrasive devices;
- if there is frost, the surface is treated with a flash gas burner– a brush or scraper will be ineffective;
- Preliminary degreasing is carried out with isopropanol and acetone.
Painting wood
It is not recommended to paint wood, products made of fiberboard, chipboard, and lining in winter. If the house is made of wood on the outside, it is better to leave painting it until the warm season. Water accumulates between the fibers of the tree, which freezes in frost. The structure of the material expands, and the paint applied on top seals it in this state along with the ice. After thawing, the water begins to push out the paint, the latter cannot withstand it and bubbles. The wood also begins to rot under the enamel.
If staining is urgently needed, a test is done first. Apply a wide strip of tape to the surface, leave it for 2 days, then remove it. If there is condensation on the tape, painting is not done. With a dry strip, painting can be done after preliminary priming.
Indoor painting work
Painting the inside of a house in cold weather is much easier than doing exterior work. But the specifics of painting must be taken into account.
Balcony
Painting a balcony or loggia in an apartment in winter may be required when selling to improve the surface of walls, ceilings, and floors. The most difficult thing to tint cold balcony– it’s better to wait until the temperature is above zero and only then carry out painting work. If absolutely necessary, you can purchase paint that can withstand low temperatures, wait for a sunny day, make sure the walls of the loggia are warmed up sufficiently, and paint.
Painting is carried out only in the morning - the coating will dry faster due to heating sun rays. If you have an outlet, you can place a heater on the insulated balcony, this will allow you to carry out the work efficiently. Acrylic water-based compositions are well suited for balconies - with their use you can avoid poisoning, they are environmentally friendly and odorless. Such paints increase thermal insulation characteristics walls, allow them to “breathe”, fade and collapse very slowly. If there are parts made of plastic or metal on the balcony, it is better to coat them with varnish. The lining is coated with acrylic varnish.
Batteries
Painting a battery in winter has a number of features. To paint the radiator, you need to prepare a brush with metal bristles, a simple brush and a radiator brush with a long handle. You will also need sandpaper, a dust brush, and a knife. Be sure to purchase a metal primer, paint, and solvent. The basic composition must be suitable for radiators and contain anti-corrosion additives and be non-toxic. The best means are:
- acrylic;
- alkyd;
- water-dispersed;
- silicone;
- based on heat-resistant varnish;
- zinc.
How many degrees can such enamels withstand? They are designed for a standard temperature of +80 degrees. Some are available in aerosol form - sold in a can, and by spraying you can easily paint even the most hard to reach places. It is better to remove the batteries for painting by turning off the water supply. If this is not possible, you should wait until the batteries are turned off in the spring. Hot batteries will be painted poorly and the coating will often swell. After cleaning the surface, it is primed and painted in 2 layers. Each layer must dry completely.
Window
Coloring wooden windows in frosty weather outside, it is undesirable, like other wood products. Only the use of heat guns will make it possible to dry the product well, but the labor intensity of the work will increase significantly. The inside is painted in the same way as it is done in warm weather. old paint you need to remove, prime the surface, then apply a suitable composition. Plastic windows You can also paint them using special paints if you want to update their color.
What paints are used in winter
Enamels and primers that are used at subzero temperatures are varied. Their properties:
- do not freeze in the cold;
- suitable for different types materials;
- can be operated at temperatures down to –10…–20 degrees;
- form an elastic layer;
- Dries faster compared to regular paint.
Water-based paints
This type of paint is most in demand in winter. The products of the companies Dufa and Batilith, Dulux and Tikkurila are very popular, which produce many types of appropriate paint and varnish materials. Good frost-resistant paints are produced by the German company Caparol. A number of manufacturers produce frost-resistant water-based paint AK-115, which can withstand temperatures down to -20 degrees below zero. Other known materials:
- Parade f20;
- Lakra;
- Alpa Façade;
- Brite Professional primer;
- Vincent Muralith F1.
Oil paints
Oil-based materials are almost never used now. Their properties are much inferior to water-based paints; their service life is no more than 2–3 years. The products need to be diluted with drying oil and special solvents. Only some paints marked PF, MA, GF are suitable for working in cold weather.
Aerosol paints
Enamels in cylinders are used, for the most part, for painting batteries, cars, and plastic products. They are quite expensive, but create high-quality coverage. Popular brands are:
- Maxi color;
- Colomix;
- Dupli-color;
- Vixen.
Most paints of this type can be used down to –15 degrees.
Storage temperature of paints and varnishes
Usually permissible temperature storage is indicated on the material packaging. According to GOST, paints and varnishes can be stored at temperatures of –40…+40 degrees, but individual conditions may exist for each specific material.
Any work in the cold is not comfortable, and if possible, it is better to postpone metal painting and carry out it in the warm season. What to do if they have already arrived winter cold, but all the planned work was not completed on time during the warm period, and the metal structures located on the street were not painted?
There is an opinion that it is impossible to paint outside in winter, or it will not work, however, it is erroneous and irrelevant. To date it has been developed a variety of paints and varnishes, which can be used in any weather.
For painting metal surfaces in winter you can. For their use, the permissible temperature range is from -20 to +35°C. At the same time, even the presence of moisture on the metal surface does not affect the quality of the coating and the ease of painting work.
If it is not possible to postpone painting the metal until the weather warms up, there are some factors to consider.
First of all, they should not contain ingredients that freeze at temperatures that do not drop to -20°C.
It is necessary to completely eliminate the use of alkyd and other coatings that increase viscosity at low temperatures.
To remove frost covering the metal, it is necessary to treat the metal surface with the fire of a gasoline or gas burner. It is not recommended to use brushes and scrapers, since after their use the surface is not completely cleaned.
Before applying the primer, it is important to degrease the surface using acetone or isopropanol.
When carrying out painting work in winter, a special frost-resistant primer is used to prime the metal surface, and it is necessary to select the composition for this type of metal.
Priming provides corrosion protection and improves the adhesion of the finish coat.
If necessary, using a special brush, before starting work, the surface is thoroughly cleaned of loose rust and dirt that creates unevenness.
The consumption of anti-corrosion paints and varnishes for painting metal surfaces in winter is the same as in warm weather. All materials intended for application at low temperatures are quick-drying. The finished coating does not react to precipitation within an hour after application. So, at an air humidity of 80-95% and a temperature of -15°C, the complete drying time will be 2-3 hours.
The service life of coating applied at low temperatures reaches 10 years if painting technologies are followed.
Should I paint a fence in winter?
What to do if the outside temperature is below 0°C and you need to paint a metal fence.
When temperature changes, the metal does not change its structure and does not absorb water. At elevated temperatures, a leaf fence can stretch a little, and when cooled, it returns to its shape. , intended for painting metal, after application, adapting to form an elastic film on the surface.
To paint metal fences in winter, enamels are used that are designed to work at low temperatures. Solvent-based alkyd paints, which do not change consistency at low temperatures, have the necessary properties.
Metal paints can also be used to paint wooden surfaces.
Before painting the surface metal fence dried and degreased with special means.
For painting, not a cold, but a warm coloring composition with a temperature above 0°C is used.
If when painting large structures If it takes a lot of time, then the container with paint is placed in warm water to maintain the desired consistency of the composition.
Special enamels designed for painting metal in winter dry from 1 to 3 hours, and regular enamels dry from 3 to 7 days.
Effective enamels, intended for use in winter, do not freeze in frost, are suitable as for metal and for wood, combine anti-corrosion, antifungal and fire-retardant properties, even in extreme weather conditions form an elastic covering layer, dry quickly compared to conventional paint compositions.
It is possible to paint a metal fence and other metal products in winter. The main thing is to choose the one intended for this and properly prepare the surface. Each product package always contains information about the method of application.
The need to paint a concrete floor, fence, facade or metal structures is also present in winter, when it is frosty outside and negative temperatures reach -15C°. Not every paint or primer copes with this task. Many paint and varnish materials cannot be used in the cold, therefore, for outdoor work in winter, special materials are needed that are suitable for use at low temperatures and provide high-quality coverage under these conditions.
NPP GC produces a number of special paints for the winter period to provide its customers with the opportunity to carry out work at any time of the year:
