How to paint a ceiling using old paint. How to paint a ceiling with water-based paint

Many beginners, before starting to paint ceilings, are sure that this is an extremely simple operation - just take the paint and paint it. In reality, this operation contains a number of nuances on which the durability and quality of the finish depends. Therefore, below we will look in detail at how to properly paint a ceiling with water-based paint using a paint roller.

Painting technology

The painting process can be divided into several main stages:

Stage 1: preparing tools

First of all, you need to choose a suitable paint roller. This task must be approached responsibly, since it is the roller that determines how beautifully and evenly the paint will lie on the surface.

The fact is that there are many varieties of this on sale. painting tool However, not all of them are equally suitable for painting the ceiling. For our purposes, it is best to use a medium-nap roller.

Avoid using a cheap foam roller, as foam rubber absorbs too much paint, causing the paint to apply unevenly and bubble. Rollers with short pile, for example, velor, absorb little paint, which is also bad.

If the ceiling is covered decorative plaster, then it is better to use a roller with long pile so that it can accurately paint over the deep texture.

The price of such rollers starts from 150-200 rubles. There is no point in purchasing a cheaper tool due to its poor quality. Keep in mind that you will need a long handle for the roller, since painting from a stepladder is not very convenient.

In addition to the paint roller, you need to prepare the following equipment:

roller tray (cuvette) – will allow you to dip the roller into paint and wring it out on a special rolling platform of the tray;
masking tape– will be needed to protect areas adjacent to the ceiling that you will not paint from contamination;
ladder stepladder – needed for touching up hard-to-reach areas with a brush.

If the ceiling is not prepared for painting, you should also prepare:

deep penetration primer;
putty;
set of spatulas;
spray.

After preparing all these tools, you can proceed to the next stage.

Stage 2: preparing the ceiling

First of all, I note that painting the ceiling requires High Quality preparation. The thing is that, contrary to the opinion of beginners, even the smallest flaws, which are practically invisible on the ceiling before painting, are clearly visible after painting. Therefore, the surface prepared for painting must be perfectly flat and smooth.

Also, keep in mind that paint should only be applied to a secure base, i.e. does not peel off and has good adhesion. The durability of the paint depends on this.

Therefore, the instructions for preparing the surface are as follows:

First of all, you need to prepare the room - remove all the furniture from it and cover the floor plastic film. If the walls are already finished, they also need to be protected. For these purposes, you can use newspapers that are glued with masking tape.
Do not use regular tape, as it will only ruin the finish;
Next, you need to remove the old finishing coating from the ceiling. If the ceiling is covered with wallpaper, the canvas should be soaked with water using a spray bottle, and a draft should be created in the room. The surface must be periodically moistened for half an hour.
When the canvases are wet, they can be easily removed by prying them off with a spatula. If you need to delete vinyl wallpapers, then you must first process them with a needle roller or make cuts in top layer coating to provide water access to the substrate.

Whitewash can be removed by blurring it. Another option is to stick newspapers onto the whitewash with wallpaper glue, and then tear them off with a sharp movement along with the glue.

As for paint, it is usually removed mechanically. To do this, you can use a special brush attachment for an electric drill or grinder;

then you need to wipe the surface with a damp cloth to remove dust, residues of wallpaper glue, chalk or other contaminants;

If there are cracks on the surface of the ceiling, they must be filled with putty. Pre-expand the cracks, and then prime them and fill them with putty, leveling the surface with a spatula. After the putty has dried, the surface must be sanded with fine abrasive sandpaper.
True, if you plan to subsequently putty the entire ceiling, sanding may not be necessary;

then the surface to be prepared must be primed using a paint roller. To do this, pour the soil into the pan, dip the roller into it, and lightly squeeze it on the tray area. Then apply the liquid evenly thin layer.
After the first layer has dried, the procedure must be repeated;

if the ceiling has uneven surfaces, it should be puttied. To do this, first apply starting putty using a wide spatula or small spoon.
The thickness of the starting layer should not exceed 1-1.5 cm. Exact value usually indicated by the manufacturer on the packaging. Get more detailed information You can learn about puttying techniques from other articles on our portal.

After the starting layer has dried, the surface should be sanded with a mesh with P80-P120 abrasive.

Then the ceiling needs to be cleaned of dust and primed again. Next is applied finishing layer putties up to 3 mm thick.

After the finishing layer of putty has dried, it must be carefully sanded so that the surface ends up perfectly smooth. To do this, you need to use a mesh with fine abrasive - P150. It is necessary to carry out the work in bright light so that you can clearly see even the smallest flaws on the surface.

All the above steps are performed only if the ceiling has minor flaws. If the surface has serious level differences or areas with peeling plaster, it must be plastered or mounted suspended ceiling from . You can learn about the nuances of this work from other articles on our resource dedicated to this topic.

Of course, many people want to simplify and speed up the preparation process. Therefore, people often ask on forums whether it is possible to paint the ceiling water-based paint By old paint?

It all depends on the type of paint. If the ceiling is painted with water-based paint, then it is not necessary to remove it, unless, of course, the old paint is peeling off. As a rule, the presence of “water emulsion” on the ceiling indicates that it was well prepared for painting and, accordingly, does not need puttying.

The only thing is that before painting the water-based emulsion, the surface must be wiped with a damp cloth to remove dust. This is necessary to ensure normal adhesion of the new coating.

If the ceiling is painted with a water-based emulsion that is not resistant to moisture, then it must first be primed. To determine what kind of paint a surface is painted on, run a wet cloth over it. If the rag becomes stained, it means that the old coating is not moisture resistant.

Stage 3: paint preparation

Now that the room and ceiling are ready for painting, you need to prepare the paint itself. If the coating is already painted in the color you need or you will paint the ceiling in White color, then all preparation of the water emulsion comes down to mixing it. If it is thick, the paint can be thinned with a small amount of water.

If the water-based emulsion is white, and you want to give it some appearance, then it needs to be tinted, i.e. add a special coloring composition (color).

This is done as follows:

First of all, you need to decide on the proportions of the color scheme. To do this, take a small amount of paint and gradually add color until you get desired color. Be sure to write down the proportion;

Next, mix the main part of the paint with the color in the resulting proportion. The paint must be mixed thoroughly. To do this, you can use an electric drill with a mixer attachment.

If you plan to paint with water-based paint over old water-based paint, it is advisable to use the same color as the ceiling or a tone close to it. Otherwise, you will have to paint the ceiling multiple times to achieve the desired color.

Stage 4: painting

Now we come to the actual painting.

This stage is the simplest and most enjoyable, however, it also contains some nuances:

pour the prepared paint into the roller tray;
then take a brush and apply paint to all the hard-to-reach places where the roller cannot reach.
Apply the paint in an even, thin layer. Make sure that there are no drips on the surface;
Now you can paint the main part of the ceiling with a paint roller. To do this, dip the roller in the paint and roll it out on a special area to remove excess paint.

Then apply a thin layer of paint to the ceiling along the direction of the light coming from the window. Try not to roll the roller over the same area twice.

Also, do not try to completely “cover” the surface the first time, getting the desired color;

After the first layer has dried, apply a second layer of water-based emulsion across the first. As a rule, it takes several hours for a layer of paint to dry completely at room temperature.

Start painting with hard to reach places, then paint the main part of the ceiling with a roller;

If the second layer was not enough, apply the third layer along the direction of the light from the window, i.e. across the second layer.

Here, in fact, are all the nuances of painting the ceiling that I wanted to tell you about.

Conclusion

Now you know that the process of painting a ceiling with water-based paint is quite simple and quick. But first, it is necessary to properly prepare the ceiling, which, as a rule, takes a lot of time and effort, especially in cases where it is in poor condition. At the same time, the technology cannot be violated, as this will affect the quality and durability of the painted surface.

To visualize the process described above, you can watch the video in this article. If any nuances of this procedure are still unclear to you, leave your questions in the comments, and I will be happy to answer you.

For many decades, painting the ceiling with water-based paint has remained one of the most popular finishing methods. This coating is environmentally friendly and universal, as, thanks to its matte finish and a wide selection of shades, it will suit any interior. The low cost of materials is one of the advantages of painting with water-based emulsion. However, for a quality result this type finishing requires careful preparation of the ceiling and some painting skills.

High-quality paint is the main component of success

For best result features should be taken into account various types water-based paint. The best option for ceilings is acrylic water-based paint; the addition of latex increases the elasticity and strength of the coating, and also allows you to repair small cracks. More economical options– paints based on acrylic copolymers (vinyl acrylic, styrene acrylic).

The largest number of positive reviews are collected by products from German manufacturers; Polish and Russian factories also produce high-quality, but less expensive paints. The main thing is that it must be factory-made and not a fake. In any case, high-quality water-based paint cannot cost less than 180 rubles per liter.

On the can or bucket of paint there should be instructions for its application and the cost of painting one square meter. Knowing the consumption, you can independently calculate how many liters of paint you need to purchase to paint the ceiling.

Immediately before work, you need to prepare the paint by adding cold water to the consistency of kefir (5-10% of the paint volume) and stir thoroughly (you can use a drill with a special attachment). If you want to give the ceiling a tint, you can add color to the paint container. You should start with a few drops, adding very gradually so as not to get too bright a shade. The resulting colored paint requires particularly careful mixing.

Tools and auxiliary materials

Most necessary tool for painting the ceiling, use a roller, since using a brush it is impossible to create a perfectly even coating on a large surface. Its size directly depends on the area to be painted; the larger it is, the thicker and longer the roller should be.

Foam rollers are more suitable for applying; for painting the ceiling, it is better to choose a roller with a small, velor-like, pile. If you want to add a light texture to the coating, you can use a long-nap roller. Plus, it takes more paint, and the job will move faster. The retractable handle for the roller eliminates the need for ladders and tables and reduces the risk of injury.

A wide (up to 8 cm) flat brush is still needed for painting corners. It is better if it has fluffy ends, in which case there will be no streaks left on the surface to be painted.

To match the length of the roller, you need to select a plastic paint tray with a ribbed spin pad. The roller is dipped into the paint and then rolled over the surface several times to remove excess paint and apply it evenly to the roller. Using this inexpensive device will greatly simplify your work and improve the quality of your painting.

Preparatory work

It is impossible to achieve a good result when painting with water-based paint if preliminary work is not carried out. By the time of painting, the ceiling must be cleared of the previous coating, glued with reinforcing mesh at the joints of the panels, leveled, puttied and sanded until smooth. You can also paint over old water-based paint, provided that it does not come off anywhere and there are no cracks in it. Otherwise, you will have to carry out all the above work. Then use a roller, and after it has completely dried, the ceiling is ready for painting.

If the ceiling is painted plasterboard sheets, then you should glue all the joints with mesh, putty and sand the screw heads. With even concrete panels ceilings without noticeable potholes and defects, you can apply water-based paint with latex in several layers directly onto the primed concrete. The latex in the paint will fill out small pores and roughness, and this coating will look quite satisfactory.

Before painting, you must remember to remove all the furniture from the room or cover it with oilcloth. It is worth taking care of the safety of the floors if they are not planned to be replaced.

Painting

They begin work by painting the corners and perimeter of the ceiling, which is more convenient to do with a brush. The strokes should run parallel to the window. The ceiling is painted from the wall with the window; if they are located on several walls, then the one from which more light comes is selected. At the same stage it is worth painting the ceiling cornices, if any.

A small amount of paint is poured into the tray, a roller is dipped into it and rolled several times, squeezing out excess paint. The paint is applied to the ceiling using small zigzag movements, evenly and gradually. While the paint has not thickened, you can go over it with an empty roller to remove excess paint. From time to time it is worth stepping aside and looking at the ceiling from a different angle to notice unpainted areas.

After completing one coat, the ceiling should be completely dry. This takes at least several hours. Do not try to speed up the drying of the paint, as this can lead to cracks and peeling.

The next layer of paint must be applied perpendicular to the previous one. For a high-quality result, at least two layers of water-based paint are applied. The last layer is applied perpendicular to the wall on which the window is located. After each painting, the rollers and tray must be thoroughly washed.

Painting tricks

Before painting the ceiling, you should practice small area walls or drywall to get used to the roller and paint.
The paint should cover the roller as evenly as possible. This will prevent unpainted areas and stains from appearing on the ceiling.
Do not roll out already set paint with a roller, this will lead to streaks and deformation of the coating.
It is better to take paint with a reserve, since even different batches of the same brand may differ slightly in color.

Home renovations almost always involve freshening up the ceilings by painting them. Only owners of tensioners and suspended ceilings(but these structures also need regular cleaning from dust and soot, which usually accumulate in corners, near windows and heating radiators).

Currently, water-based paint is most often used to paint the ceiling.

Water-based paint can be:

Polyvinyl acetate - has low resistance to moisture, so can only be used in dry rooms. Please note that the painted surface cannot be washed.
Latex - fits well various grounds, washes well, but has a fairly high cost.
Silicate - its basis is liquid glass. The paint adheres well to concrete and stone surfaces, therefore it is often used for finishing industrial premises. The paint has good water resistance and elasticity. It is rarely used in residential buildings, since its properties are not in demand here, and the cost is significantly higher than the average level.
Acrylic is the most common option, widely used for residential premises. The paint has quite high performance characteristics. There is also a gradation according to the type of premises, degree of whiteness, resistance to moisture and even according to the type of surface to be painted (“for walls”, “for ceilings”). Cost of trains of this type quite accessible to the general population.

The presence of such a wide range allows you to choose a colorful composition to perform any task.

But only the acquisition of the most suitable paint does not guarantee that after repair the ceiling will have exactly the quality you expected.

To do this, other conditions must be met:

Objective assessment of the quality of the ceiling surface to be repaired.
Proper preparation of its surface for painting.
Painting in compliance with technology requirements.

Possible options for preparing the ceiling for painting

Preparatory work has a great influence on the result of the work. To carry them out correctly, you need to carefully examine the ceiling and find out what paint was used for its previous painting.

It should be noted that the best option for preparing the ceiling is:

complete removal of all layers of previously applied paint;
surface treatment with a primer;
puttying the most noticeable defects or even the entire surface;
sanding putty areas;
re-priming.

But this preparation procedure requires considerable time and labor costs. In addition, it is associated with education. large quantity dust and dirt, which is almost impossible to avoid.

Therefore, many people ask the question: “Is it possible to somehow avoid all these difficulties. Is it possible to paint the ceiling with water-based paint over a previously applied coating?

There is no definite answer, you need to consider options:

If the ceiling is replete with defects, including large ones, then it is easier to remove the old paint, put it in order and then paint it again.
If previously the ceiling was not painted, but whitewashed with lime, there are no options - it will have to be completely removed, and then the progress of the work depends on the quality of the cleaned surface.
If the ceiling was previously painted with a water-based composition that is not resistant to water, then the old layer will have to be completely washed off or removed with a spatula, since the application new paint will certainly cause the old layers to peel off, which will inevitably spoil the appearance of the ceiling.
If the ceiling was painted with a waterproof emulsion, then you can take a chance and not remove it, but you still need to prepare the ceiling for fresh painting.

How to prepare a previously painted ceiling

So, if it turns out that the previous painting was done with a waterproof composition, then the surface must be prepared in a certain way.

That is:

The ceiling surface must be cleaned as best as possible from contaminants by rinsing with water.
If areas of mold are found, it must be destroyed. special means, and treat the surface with an antiseptic.
Next, the surface is inspected for defects such as: peeling of a layer of old paint, deep cracks, depressions and bumps. Some of them will appear at the stage of wet cleaning of the ceiling.
Areas where the paint is peeling will have to be cleaned with a spatula. Lumps must be removed by scraping or grinding.
Then all these places need to be treated with a primer and puttied, achieving maximum leveling with the rest of the surface. Big changes may require the use of plaster rather than putty.
Then all putty areas (or better yet, the entire ceiling) must be primed. If the surface actively absorbs the primer, then 2 times are possible.

Upon completion of this work, you need to wait until the putty areas and primer have completely dried, and only then can you begin painting.

Painting the prepared ceiling surface

The correct painting technology plays an important role in how high-quality the result will be.

For painting you will need:

dye;
brush;
roller

The paint should be chosen according to the type of room - living room, kitchen, bathroom. There are special compositions for bathrooms that are also good for kitchen ceilings. They often contain biocidal additives and components that prevent yellowing of the paint due to temperature influences.

Painting can be done with a brush or roller. However, even if you decide to use a roller, you will also need a brush. It is convenient to paint the ceiling in the corners and around the perimeter.

For painting the ceiling with water-based paint the best tool will become a roller with a fur coat (ideally made of sheepskin). It is this tool that guarantees the application of the paint composition as smoothly and efficiently as possible.

The painting technology itself is as follows:

Opening a can of paint and mixing it thoroughly, including the lowest layers (sometimes the composition may separate during storage).
If the paint is thick, you can dilute it with water, according to the instructions on the label. Usually water is added in an amount of 5-10% of the paint volume. In this case, the composition should have the consistency of liquid sour cream.
The prepared paint is poured into a special tray, which allows you to evenly saturate the entire surface of the roller with paint.
Then the roller is rolled out on the ribbed surface of the tray - this allows you to remove excess paint and prevent it from splashing during operation.
Those places where using a roller is difficult are pre-painted with a brush.

Next steps depend on how many layers of paint you plan to apply. Usually this is 2 or 3 layers. Proceed from the fact that last layer paints are applied in the direction luminous flux, coming from the window - this makes the joints between the stripes of the roller or brush invisible.

In this case, successively applied layers of paint must be perpendicular to each other - this is how you can accurately paint all the small unevenness of the ceiling.

That's why:

If you plan to paint in 2 layers, then the first layer is applied across the direction of the light, and the second – along.
If it is necessary to apply 3 layers of paint, then the first and last layers are applied along the light, and the second - across.

Applying each layer of paint requires the previous one to dry completely. The drying time is indicated on the paint can, but in any case it should be 6-12 hours. You cannot apply a second layer of paint to a still wet base; this may cause the undried layer to begin to “stretch” behind the roller or brush, which will ruin the appearance of the ceiling.

Thus, it is possible to paint the ceiling with a water-based composition over old paint. But this option requires no less careful approach than options for removing the old coating, and is not suitable in all situations.

One of the most popular finishing options today is painting with water-based paint. But sometimes such finishing is complicated by the presence of old paint. This article will tell you what needs to be done in order to paint a ceiling with an old layer of finishing.

Today, painting the ceiling with water-based paint is considered the most preferred and popular option. The times when various chalk and lime mortars were used for finishing are a thing of the past. Therefore on this moment coloring compositions are characterized by significant diversity. The range of water emulsions, as one of the most popular types, today is also quite large. As a result, the painting process ceiling surface if you have an old layer, you should start by selecting suitable material finishing.

Today, water-based paint is represented by the following compositions:

Acrylic. These are the most common compositions today. They are characterized by high performance characteristics, as well as gradation for various types of premises. Therefore, among them every person will find best option. The cost of acrylic compositions will be slightly higher than the average among offerings in the paint and varnish market segment.
Latex. These compositions fit perfectly on a variety of surfaces. At the same time, the resulting finish is perfectly washable. The only drawback of such compositions is the cost, which will be several times higher than that of other products.
Silicate. The basis of such products is liquid glass. An excellent basis for silicate compositions is stone or concrete surface. Moreover, they are most often used for finishing production premises, but silicone compounds are used extremely rarely for the home. The peculiarity of such paints is that they are elastic, moisture resistant, and can also mask cracks up to 2 mm. But their cost is higher than the average market price.
Polyvinyl acetate. This finish cannot be washed, as the material has low moisture resistance. Therefore, it can only be applied to the ceiling in dry rooms.

As you can see, the range of paint and varnish products is quite extensive and can satisfy any requirements. Therefore, before purchasing finishing material It is necessary not only to know the parameters of the room where the repairs will be carried out, but also to study in detail the capabilities of the available coloring compositions. But many experts recommend giving preference to a coating that, once applied to the ceiling, can be washed. Such compositions will allow you to keep the surface clean, and not have to do repairs every time for the purpose of updating.

Preparation

If you decide to refresh your ceiling with a new paint composition, then for the success of the painting work you should carry out high-quality preparation. Even if the surface is finished with water-based paint, the old finish, whatever it may be, must be cleaned off. This is due to the following reasons:

the layer of paint has already lost its former attractiveness;
cracks have appeared on the ceiling, due to which a collapse is possible after applying a new layer of finishing to the surface;
Mold may well develop under the old layer of finishing, which will lead to the fragility of the repair.

Removing the old layer of water-based paint from the ceiling surface is carried out as follows:

We wet the old coating generously with water. You can use a hand sprayer or roller for this.
Next, leave the surface for some time for better soaking.
After 20 minutes, repeat the wetting procedure. In this case, windows and doors must be open.
After about 30 minutes, bubbles will appear on the ceiling. Take an iron spatula and scrape off the old coating.

After removing any finishing residue, rinse the surface thoroughly. clean water. To do this you need to use a foam sponge. If there are defects in the starting surface (cracks, potholes, etc.), they should be covered with putty. When it dries, use sandpaper or sandpaper, the surface should be leveled.

For putty, many experts advise choosing universal polymer compounds. They are, of course, more expensive than cement or gypsum, but it will be much easier for beginners to work with them.

Please note that if there are strong differences in the surface, it is not recommended to fix this kind of defect with your own hands. To do this, it is better to call an experienced plasterer or install suspended ceiling structures.

If the differences are no more than 3 mm, then there are two alignment options:

Applying plaster in the right places. For these purposes it is necessary to constantly use a level.
Usage ceiling tiles. It can be painted very easily and quickly with water-based paint. At the same time, you can choose various decorative patterns using such slabs.

After all the manipulations described above, in order for the painting to be successful, the prepared surface must be primed. The priming process itself is not complicated. But if this is not done, the final finish may become stained in the future, which will ruin its aesthetic appearance.

For priming, you should use professional solutions that have deep penetration. In this case, for greater effect, apply the primer in several layers. It will be enough to prime twice.

Some people, in order not to spend money on buying a primer, prepare it themselves. For these purposes, purchased water-based paint is suitable, which is simply diluted with water. By the way, any composition fits perfectly on itself, even in diluted form.

It is also worth noting that after removing the unusable finish, mold may be exposed. To combat it, special antiseptics should be used. They not only destroy existing mold, but also prevent its reappearance in the future.

Instead of expensive antiseptics, you can use self-prepared solutions (for example, a five percent solution copper sulfate). Treatment should be done after removal old decoration and before puttying or applying primer.

By correctly and consistently performing the above-described manipulations, you will be properly prepared for painting.

Dyeing technique

The staining technique includes two important stages:

choosing a tool for painting work;
painting a previously prepared surface.

Let's look at each stage in more detail.

Painting ceilings always begins with choosing a tool. Painting can be carried out with the following tools:

Tassels. In order to effectively paint any surface, you need to use brushes. different sizes. It is worth noting that brushes are not very effective for large areas of work. However, they do not allow you to apply the coloring composition in an even and thin layer. They can be used to qualitatively paint various decorative convex finishing elements, as well as the junction of walls and ceilings.
Roller. It is considered the most effective tool, but only when correct selection. The dimensions of the selected roller directly depend on the area to be painted. The larger the area, the thicker and longer the roller should be. In this case, you need to pay attention to the material from which the roller skin is made. Different skins are suitable for different paints. To work with water-based compositions, you should choose velor skins and those that have a long pile. Also, for working with the ceiling, you need to choose products with a long handle. It will allow you to effectively carry out Painting works without using stairs.
Professional spray gun. This tool is much more expensive than a roller and brush. Moreover, not everyone can cope with it.

Experts recommend using a roller for painting, since with its help you can quickly and efficiently apply an even coating to a fairly large area. large areas. But in this situation, brushes will still be needed to paint the corners. Please note that the paint tray should be selected depending on the size of the roller purchased.

Do not forget that you need to apply the water-based emulsion only when the base is completely dry after priming.

Painting the ceiling with water-based paint is carried out according to the following algorithm:

Open the can of paint and mix it well, touching the lower layers. This must be done in order to obtain a uniform color of the composition.
Next, pour the paint into the tray.
First you should paint the corners and all places that are inaccessible to a roller. To do this we use a brush.
After this, dip the roller into the poured composition.
On the raised area of the tray, squeeze the roller so that paint does not drip from it. As a result, the composition will be evenly distributed over the surface of the roller.
The first layer should be applied parallel to the direction of the natural light available in the room. One area should be covered with a roller several times to avoid dark spots and sagging. Painting is done with an overlap on the previous strip. Moreover, the entry should be half the size of the roller. It is best to make W-shaped movements.

No one can do without painting the ceiling. redecorating. For this purpose, water-based polymer-based compositions are used. From correct use paint quality depends appearance ceiling. Beginning painters often face the problem of divorce. They appear due to improper painting technique.

This article will be useful to those who want to learn how to avoid such problems. It describes in detail the rules and techniques of painting, observing which you will be able to prevent the occurrence of stains. But before you start painting the ceiling, you need to choose the right paint composition.

Choosing water-based paint

The consumer market has a rich assortment of water-based paints of different compositions and purposes. To avoid mistakes, carefully read the label on the jar. It indicates the type of composition and method of application. There are four types of water-based paints:

silicate;
acrylic;
silicone;
latex.

In ordinary rooms, paints containing latex and acrylic are used. They dry quickly, do not emit pungent odors, and are resistant to wet cleaning using chemicals.

In rooms where the humidity level is high, paints based on silicone and silicate are used. For example, in the kitchen and bathroom. Due to its composition, they create a vapor-permeable layer on the surface that absorbs moisture and then slowly evaporates it.

Before applying water-based paint, carefully prepare the ceiling. To do this, remove the old layer of whitewash. If the ceiling has damaged areas, repair the defects with putty. Level the entire surface and prime it at the end.

Cleaning the ceiling. To delete lime whitewash, wet the surface well. This is done with a water spray or a regular roller. For achievement maximum effect do this procedure twice with an interval of twenty minutes. Lime will absorb water well, this will help to easily remove it from the surface. To scrape off the whitewash, use a metal spatula. After cleaning, wash the ceiling with a sponge.
Elimination of defects. Expand and fill any cracks or chips that appear finishing putty. Do it in small portions, trying to rub it in deeper. After allowing time to dry, sand the putty with sandpaper.
Leveling the surface. While eliminating cracks and chips, you may have noticed that the ceiling has uneven areas. To fix this, use a thin layer of putty. It has plasticity and adheres well to the surface. To apply putty, use a wide spatula. In areas with large depressions, apply several layers. Achieve a perfectly flat surface over the entire ceiling area.
Ceiling primer. After leveling the ceiling, it must be primed. The primer fills micropores, makes the putty surface smooth, and improves the adhesion of water-based paint. Apply the primer in two layers at intervals of 15–20 minutes.

Required Tools

To apply water-based paint to the surface without streaks, choose the right tool. Pay attention to this stage Special attention. For painting you will need the following tools:

A roller is the main tool in painting. It has a foam and fur surface. To paint the ceiling with water-based emulsion, it is better to use rollers with a fur coat that has a medium pile length. Foam rubber creates small air bubbles when rolled - this should not be allowed! And the fur coat leaves behind a relief mark that masks minor scratches well.
Brush – Used to paint areas that a roller cannot reach. Ideal for spot work in areas close to the wall. To make this process convenient, it is better to use brushes with a medium head size.
A tray is a plastic tray with a small recess that is filled with paint. It is convenient to use for dipping a roller.
Construction mixer – used for thinning paint.
Polyethylene and masking tape will help protect walls and furniture from getting paint solution on them.
Protective equipment: work clothes, glasses, hat and gloves.

If you plan to paint the ceiling in two or three shades, then for each color you need to use a new brush, roller and tray. Using the same tool for the entire job will blend the shades. The result will be a different look than was intended.

Rules for painting the ceiling

When painting a ceiling with water-based paint, many people make mistakes. There are nuances that are important to know about. For example, it is necessary to take into account the rays of light or the order in which areas are painted. By following the rules, you will be able to make the ceiling surface streak-free.

Always start painting from the corners, and then the rest of the area.
Apply several layers of water-based paint at intervals.
Allow twelve hours for each layer to dry.
When finished, cover the windows with a cloth to prevent light from shining onto the surface. Sun rays can leave dark spots on the ceiling.
Do not allow a draft to appear in the room until the water-based coating dries.
Do not dry the ceiling with electrical devices.

There are several technologies for applying water-based paint. The choice of method depends on the conditions in which it will be used and the type of coating. In our case, it is necessary to make the surface streak-free. To make the paint look pleasing for a long time, use following tips regarding dyeing technology:

Start painting from the corners and borders where the wall and ceiling meet. Determine the furthest from front door corner. Dip the brush into the paint and brush it around the perimeter of the ceiling. The width of the line can be 5–10 cm. This is done so that when working with a roller, you do not touch the walls.
Having finished working with the perimeter, start painting the main area of the ceiling. Fill the patch with water emulsion and dip the roller in it. Then roll it well on white paper so that the paint evenly saturates the pile and begin painting the ceiling.
Hold the roller at a 45-degree angle, making sure it is not over your head.
Apply the first layer parallel to the rays of light falling on the ceiling. Make the second pass perpendicular. The third layer should be applied in the same way as the first.
Make parallel movements with an overlap of 5 cm. Make sure that the layer is applied evenly. Do not roll over one place many times - an influx will form.
To remove excess water-based emulsion from the ceiling, walk over the area with a dry roller without paint - its coat will absorb the excess.
Use a bright, focused beam of light, such as a flashlight, to determine the quality of the surface.
Apply the final coat with a new roller; this will help ensure uniform distribution of the paint composition and prevent streaks.

Water-based paint is an affordable way to create beautiful ceiling. In order for the quality of work to be at its best, you need practice and adherence to simple techniques. The result will be a surface that will delight you with its uniformity.
