We paint the ceiling with water-based emulsion: from preparation to the last layer. Painting the ceiling with water-based paint over old paint Painting the ceiling over water-based paint

Finishing the ceiling, including painting it, is perhaps the most time-consuming part of the renovation. Modern technologies greatly facilitate this process. Particularly popular in Lately water-based paints are high-quality materials that are quite easy to use. But painting the ceiling with water-based emulsion also has its own secrets and features that must be taken into account when working.

Required tools and materials

First of all, you need to choose the right paint. According to its composition, water emulsion is:

acrylic;
silicone;
silicate;
latex.

But even the composition is not the most important thing you need to pay attention to. More important indicator is the hiding power of the paint. It is very easy to find out: the greater the quantity square meters, for which 1 liter of paint is enough, the better.

Wide color palette- far from the only advantage of water-based paints

If you are going to treat ceilings in rooms with high humidity(for example, in the kitchen or bathroom), buy water-based paint for wet areas. Do not forget about the presence of anti-mold components in its composition. In addition, the paint for such rooms must be washable. In dry rooms, you can use regular water-based emulsion.

Carefully reading the label on the jar will help you make your choice. Certain inscriptions require explanation.

“The paint is highly resistant to dry abrasion” - the painted surface should not be exposed to moisture. Cleaning only with a vacuum cleaner or dry cloth.
“The paint can be used in dry rooms with reduced operational load” - for painting the ceiling in the kitchen and bathroom, where high humidity And a large number of greasy fumes, this product is not suitable.
“Indelible paint with high abrasion resistance” - ceilings painted with this paint can be easily and painlessly wet cleaned without the use of special detergents.
“The paint has high resistance to abrasion during intensive washing and dirt-repellent properties” - best coverage for the ceiling. You can easily wash the surface even with detergents.

The choice between glossy and matte water-based paint depends only on your taste. But please note that matte finish will visually increase the height of the room, mask small defects, but will be difficult to clean. Glossy paint looks more impressive, is easier to clean and does not wear out for a long time, maintaining its quality characteristics. But it will easily reveal all the minor flaws on the ceiling. It is believed that the best choice- semi-matte or semi-gloss paint.

Note! If you buy several cans of water-based paint, ask that they all come from the same batch. Otherwise, the paint may be different shades. It is also important that a store selling such paint have an insulated warehouse: low temperatures lead to disruption of the structure of the water emulsion and loss of its quality.

Also, be sure to purchase a primer - it must be used when painting. If you need to repair the ceiling, then buy another solution for washing off the old paint and putty.

A can of water-based paint, a brush, a roller and a tray - everything you need for the job

Now let's move on to the tools necessary for the job. You will need:

putty knife;
paint bath;
a roller about 20 cm wide with medium pile (velor and foam coats are absolutely not suitable);
fine-grain sandpaper;
a thin brush 5–8 cm wide for painting corners and edges.

You probably noticed the remark about the lint roller. The fact is that a foam roller will leave bubbles on the surface, and velor does not absorb enough paint, and you will have to dip the tool into the bath very often. Please take this into account when purchasing.

The telescopic handle for the roller will help you do without a stepladder

If for some reason you do not want or cannot use a stepladder when painting the ceiling, a telescopic handle for a roller will help you.

Preliminary preparation and treatment of the ceiling

Before you start painting with water-based emulsion, the ceiling needs to be prepared for subsequent work.

To get a positive result, do not paint the ceiling with water-based emulsion over the old layer. It must be removed with a spatula, using an alkaline detergent, and then rinse the ceiling clean water and let dry.

To simplify the task, use this simple technique:

Wet the ceiling with plenty of water (you can use a spray bottle or foam roller for this).
After half an hour, repeat the procedure. The old coating will be thoroughly saturated with moisture.
The next step is to create a draft in the room. Open all windows and doors, and bulges form on the surface of the ceiling. You can easily remove such a soaked layer of old coating with a spatula.

After such pre-treatment, errors may become noticeable on the ceiling surface. They are quite easy to eliminate: open all the cracks and treat them with finishing putty. After it dries, the surface should be rubbed with sandpaper, and the dust should be wiped off with a damp cloth or vacuumed.

When preparing the ceiling for painting, it may be necessary to eliminate minor errors

Now start priming the ceiling. Use a primer for this deep penetration. When it dries, paint can be applied to the surface.

An overly uneven surface with potholes and multi-level tile joints indicates the need for major repairs.

The process of painting the ceiling with water-based paint

It’s good that progress does not stand still, and to perform the same work you can use not only several methods, but also various auxiliary devices. For example, you can paint the ceiling with water-based emulsion manually or using a spray gun.

Painting with a roller

Carefully remove the lid from the jar and stir the contents thoroughly. In some cases, water-based paint needs to be diluted to the desired thickness with water (information about this is usually contained in the instructions). Typically this requires no more than 10% water of the total volume of paint.
Open the can, stir the paint and, if necessary, dilute it with water
First of all, paint the corners and edges of the ceiling along the walls with a brush. This will help you avoid staining the walls during subsequent work.
Start by painting the corners and edges with a brush.
Pour a small amount of paint into the paint tray. Dip a roller into it and roll it over the corrugated surface so that the paint is evenly distributed and any excess is removed.
Load paint onto a roller and wipe off excess onto tray
Start painting from the window across the direction of the sun's rays, gradually moving deeper into the room.
When the first coat of paint has dried, you need to apply a second one. This should also be done from the window, but along the direction of the sun's rays. This way you will eliminate all the unpainted areas that escaped your gaze, but would definitely appear over time.
This diagram will tell you how to properly apply layers of paint to the ceiling.
Carefully remove small bumps and bubbles found after the surface has dried with fine-grained sandpaper.
Minor blemishes that arise during the process can be rubbed off with sandpaper and, if necessary, painted over with a brush.

The whole process, taking into account the drying of the layers, may take you several days. It is recommended to carry out painting work morning and early evening: during this period, the sun's rays fall on the surface optimally, this will help you correctly assess how evenly the paint has applied.

Using a spray gun

This type of work will bring you pleasure: it is quick and easy compared to using a roller. The most important thing in the process is to achieve a thin, as uniform layer as possible.

1. Before you start painting the ceiling, move the device nozzle away from the surface to be painted, since the spray gun throws out a lot of paint in the first seconds.

Before starting work, remove a small amount of paint from the device.

2. When the spray becomes uniform, begin painting the ceiling. The distance between the spray gun and the ceiling surface should be from 30 to 50 cm. Move the nozzle at a speed of about 5 seconds per 1 linear meter. In this case, direct the jet strictly perpendicular to the ceiling surface to be painted.

Hold the spray gun at the required distance from the surface

3. To simplify the process, mentally divide the surface into squares. Paint them one by one, first moving across, then along. At the same time, do not linger for a long time in one area, otherwise the layer will turn out thick and the paint will flow down. Maintain a steady pace while painting.

You need to work with a spray gun according to the already known scheme: one layer - across the direction of light, the second - along

Secrets and features of work: how to avoid mistakes and correct shortcomings on the go

If during the painting process you violated the technology and applied water-based paint unevenly, places with different shades may form (the light from them is reflected in varying degrees intensity), to avoid this, observe the direction of painting.

Do not try to correct such inhomogeneities until the surface is dry - this will aggravate the problem. Wait until it dries completely and apply another layer to hide the imperfections. If this does not help, remove the layer with sandpaper and apply again.

When painting a plasterboard ceiling, do not use paint that is too diluted with water. It can soak the paper layer finishing material so much so that the surface becomes covered with bubbles and begins to peel. And since the ceiling is not your walls, heartless gravity will do its job to the point where the surface will have to be completely repaired. We don't pursue such goals, right?

It is better to paint a plastered ceiling with a water-based emulsion using a spray gun. This device will distribute the paint on the ceiling much more evenly than a roller. But don't forget to apply primer first.

If the ceiling was previously whitewashed, it is better to wash off the old layer. Water-based paint applied to lime or whitewash will not only lie unevenly, but will also begin to peel. The same applies to old paint: if it has slight damage, remove the layer.

Small mistakes and errors in painting the ceiling can be easily corrected with a roller and brush

To avoid streaks on the ceiling during painting, first apply a layer of diluted water-based paint with a wide roller. After drying, you can easily see all the flaws. When you carry out the main painting, pay attention special attention on these areas and treat them more thoroughly.

Be sure to follow the direction of the layers: the penultimate layer should be perpendicular to the window, and the last one should be parallel. Don't rush - wait until the layers are completely dry.

Excess applied paint can be removed in the following way: run a roller with no paint left on it over the surface, and its pile will absorb all the excess.

Errors when working with a spray gun

If you do not move the spray gun nozzle quickly enough when working, the water-based emulsion will collect in small drops on the ceiling. Squeeze off the excess with a sponge and, after waiting for it to dry, apply another coat of paint.

Too much thick layer will lead to paint peeling. Places where peeling has appeared should be puttied, sanded and primed, and after drying, repaint. It is advisable to apply another coat of paint.

If there are some shortcomings in painting with a spray gun, you may need additional putty and primer

After painting, did small bumps and grains appear on the ceiling? Surely the paint used was dirty to begin with. To get rid of such defects, go over the entire surface of the ceiling with sandpaper and paint again, only first strain the paint through gauze.

As you can see, it is enough to follow the recommendations and simple rules so that painting the ceiling with water-based paint does not become too problematic and time-consuming for you. And the roller and the spray gun - excellent helpers in this matter, and our advice will certainly make your task easier. Share with us in the comments your experience of painting the ceiling with water-based paint or ask questions on the topic. Good luck to you and comfort to your home!

How to paint a ceiling with water-based paint? The abundance of the most different ways finishing does not exclude the popularity of painting the ceiling today. This coating attracts with its affordability and the ability to do all the work yourself. However, not everyone knows how to properly paint a ceiling with water-based emulsion.

The article talks about the nuances of preparing the base for applying paint, and about the technology of painting the ceiling with water-based paint with your own hands.

What compositions are used to paint the ceiling?

In the old days, the most popular ceiling coverings were chalk and lime mortars. The only advantage of such coatings is their low cost.

Now similar works made with water-based paints:

The most popular of this type of coating are acrylic paints. Their features:
1. enough good properties during operation;
2. usage different compositions depending on the type of premises where repairs are required.
Compared to other similar ones, their cost is slightly higher.
To paint the ceiling you will need:
- Spray gun (see Types of spray guns: how to choose the right one). Using such a device is the most convenient, fairly fast and high-quality coating application method. But such a device costs quite a lot of money, which is often beyond the reach of the average person who likes to do the repairs themselves. In this case, you should use cheaper tools, which are shown in the photo.
- Paint roller- This is the main tool for finishing the ceiling.

The problem of how to paint a ceiling with water-based paint, commonly called water-based paint, remains relevant today, despite the emergence of many newer and modern finishing materials.

Water emulsion - what kind is it?

For many decades in a row, water-based paint has been the most popular finishing option for ceiling surfaces. Everyone liked its versatility and high environmental friendliness, as well as the opportunity to choose the desired shade for interior design.

Ceilings painted with water-based emulsion long time retain their aesthetic appearance, and caring for them is as simple as possible. At the same time, the cost of such paint is low, which reduces the cost of repair work.

A water emulsion is a suspension consisting of pigment elements and polymer particles that dissolve in certain proportions with prepared water. After such a composition is applied to the surface to be painted, active evaporation of the liquid contained in the paint begins. At the same time, the polymer particles are reliably bonded to the ceiling and form a coating that is highly resistant to high humidity.

To achieve the highest quality result of painting the ceiling with your own hands, you should choose the right water-based composition. Such paints include a variety of additives that can radically change the properties of the water-based emulsion. Can be used for ceilings the following types water-based compositions:

Polyvinyl acetate. The cheapest paints. Surfaces treated with them must not be washed. May only be used in dry rooms. Cannot be used in the kitchen or bathroom.
Acrylic. This is perhaps the most popular type of water-based paint, which perfectly protects the ceiling from moisture. Acrylic compositions are used in any room. Ceilings painted with them can be washed repeatedly and thoroughly.
Latex. Paints that can level ceiling surfaces. There is only one drawback of such compositions - they are expensive.

To paint ceiling surfaces, experts advise choosing semi-matte and semi-gloss water-based emulsions. The former are able to “disguise” minor flaws in the ceilings, while the latter do not hide existing defects, but are easy to care for.

How to prepare a ceiling for painting with water-based emulsion?

Without preliminary preparation You cannot paint the surface with a water-based composition. It is imperative to remove old paint or whitewash from the ceiling. Lime and chalk whitewash is removed with a roller to painting works, which is moistened with water, and a metal spatula (they use it to scrape off the “ingrained” coating). After this treatment of the ceiling, it will need to be thoroughly washed with a sponge.

It is more labor-intensive to remove old water-based emulsion with your own hands. As mentioned, water-based paint adheres very tightly to the ceiling. Therefore, it is unrealistic to remove it by wetting it with a roller. You will have to work hard to remove peeling sections of the old coating from the surface. This procedure is best performed with a paint spatula.

You can simplify the process as follows:

moisten the old coating generously with water twice (with a foam roller or from a spray bottle);
create a draft in the room;
remove swollen pieces of old paint.

Use the described technique to greatly facilitate the process of removing the old coating with your own hands.

After cleaning the ceiling, it needs to be leveled. Typically, thin-layer plastic putty is used for these purposes. She adheres perfectly to ceiling surface and makes it really smooth. You can additionally sand the putty layer using fine-grain sandpaper.

It can also be done in another way, using a special oil-based whitewash-putty. It needs to be distributed with a brush or roller (as evenly as possible) over the surface on which all existing gaps and cracks have been previously sealed. Then it will be right thin layer prime the ceiling with the water-based paint you plan to use.

Now the surface is completely ready and we will describe in detail how to paint the ceiling with water-based paint.

Using water-based paint requires knowledge of the rules for its application. If you do not study them, as a result of painting work you will get a ceiling with pronounced dark and light spots, stripes from the passage of a roller or brush, and conspicuous unevenness in the painting. The recommendations below will help you avoid this.

Always start painting at the joints and corners between the ceiling and wall surfaces. The corner that is located at the maximum distance from the entrance to the room should be treated first. Coloring these problem areas done with a wide paint brush. It needs to be half-moistened in water-based emulsion and squeezed out a little, making a 3-5 cm pass around the entire perimeter of the room. Thanks to this technique, when you use a paint roller, the corners and junctions of walls and ceilings will be similar in shade and uniformity of application to the rest of the surface.

The main work on painting the ceiling with water-based emulsion is carried out with a roller. With its help, you need to perform three passes. The first pass of the water-based emulsion is carried out parallel to the sun's rays entering the room through the window, the second - perpendicular to the window, the third - in the direction of the window opening.

After each painting, you should wait at least 8 hours (optimally 12) and only then apply the next layer of paint.

Follow these tips, and you will absolutely be able to paint the ceiling with your own hands correctly and without difficulty. The technology for painting the surface with water-based emulsion is quite simple:

Fill a wide container (for example, a small tray) with paint.
Moisten the roller in water-based emulsion and evenly distribute the composition over it (just run it over a rough surface a couple of times with a painting tool).
Make the first pass (lead the roller from left to right) from the corner in the room farthest from the entrance, then pass again, but now from right to left.
Remove excess water-based emulsion from the ceiling with a dry roller - run it over the painted surface and it will collect all the unnecessary paint.

Note! It is recommended to do the final painting with a new roller. Then the ceiling will be truly evenly painted and without the slightest flaws.

While the surface painted with water-based emulsion is drying, it is necessary to protect the room from the penetration of sun rays and drafts. Do not use heaters or other electrical appliances to dry applied paint.

Painting the ceiling with water-based paint - necessary measure when the surface needs to be given new color or refresh the existing coating. Remedy for water based does not have a strong odor, so repairing the ceiling, in particular painting with such paint, is recommended even in a nursery.

How to paint a ceiling with water-based paint? To do this, you don’t need a lot of experience or complex devices; you just need to choose the application method and the appropriate emulsion.

Besides the absence unpleasant odor and faster drying, this type of coating has other advantages:

environmental Safety;
easy to tint;
easy application;
Easy to clean tools after finishing work.

It is better that painting and updating the ceiling with water-based paint is carried out with material from the same batch.

How to do right choice coloring composition? Emulsion paint for water-based ceilings has the following characteristics, which you need to pay attention to when choosing the right one:

For which premises is this or that emulsion suitable? There are options on sale for dry rooms, with high humidity (kitchen, bathroom, etc.), for rooms where frequent wet cleaning is required (corridor, hallway, etc.).

The presence of antiseptic, antifungal components. It is advisable to whitewash the ceilings in the bathroom or kitchen or paint them with a water-based emulsion with such additives. It is especially recommended to use ceiling silicone water-based compositions. They create a vapor-permeable layer and can be applied without prior primer.

Washable emulsion or not. There are three types of water-based compositions: completely unsuitable for wet cleaning(they can only be cleaned with a vacuum cleaner or a dry cloth); indelible (suitable for frequent wet cleaning without special means); suitable for cleaning using detergents.

The degree of gloss of the painted surface. Water-based emulsion for any ceiling can be matte, semi-matte, deep-matte, glossy and semi-gloss. Matte ceiling seems higher, invisible on it minor defects, but it is difficult to wash. Glossy looks better, does not wear out longer, is easy to clean, but even a small flaw will be visible on it. It is optimal to choose a semi-matte or semi-gloss water-based emulsion.

Emulsion consumption per 1 sq. m of surface. This indicator is associated not only with the cost of painting work, required quantity cans, but also with layer density (coverability). When choosing a composition based on this characteristic, you need to take into account that the amount of material used depends on the quality of the surface. Painting a ceiling with an uneven absorbent surface with water-based paint will require more material consumption.

Removing old coating

How to renew a ceiling painted with water-based paint? Be sure to wash off the previous coating. Painting the ceiling with old paints will not allow you to achieve good result, the new layer will peel off. Washing is done using a special solution. Procedure:

Wear a respirator and protective gloves.
Before applying the product, open windows or otherwise provide ventilation.
Apply the composition in an even layer to the ceiling surface. The paint will begin to bubble and crack.
After the reaction is complete, carefully remove the coating layer with a spatula.
If necessary, reapply the remover.
Sand the surface with sandpaper.

Painting the ceiling with water-based paint over old lime paint or whitewash is also impossible. They need to be removed. The whitewashed surface does not adhere well to the new coating. You can remove the whitewash with a roller generously dipped in water. It is better to change the water several times during the washing process. Clean off the whitewash soaked in water with a spatula.

Surface preparation

Before you paint the ceiling, you need to prepare it. What do you need for this? Cleared of old coating or new ceiling washed to remove grease and other types of contaminants. To do this, it is washed with a solution detergent and then rinse with clean water. If there are small defects on the surface, they can be puttied finishing putty. After it has dried, the treated areas should be sanded with sandpaper and the resulting dust should be removed with a wet cloth. Then it is recommended to apply a primer to the ceiling.

This is necessary in order to:

level the surface;
prevent the appearance of mold, mildew and other dangerous bacteria;
reduce the consumption of the coloring composition;
ensure high-quality adhesion of the coating to the surface to be painted.

The type of soil is chosen taking into account the nature of the material from which the ceiling is made. It is better to apply the primer with a short-haired roller; foam rubber will leave streaks. First, coat the ceiling in one direction. After the first layer has dried, the second is applied across it.

Advice! For the primer, you can use a water-based emulsion, heavily diluted with water.

Painting with a roller or brush

How to properly paint a ceiling with water-based paint? To do this, use brushes, a paint roller or sprayer. IN industrial scale use airless spray technology. The chosen tool determines the method. For home use, it is better to choose a roller. Not every home has a sprayer, and a surface painted with a brush always has a serious drawback - visible strokes.

What kind of roller is needed? Not only the material is important, but also the nature of the surface. A roller for water-based paint should optimally have a medium pile length. Short pile absorbs little, so you will often have to dip it in the emulsion. Long pile collects a lot, which leads to significant weighting of the instrument. A foam roller is not suitable at all for painting the ceiling with water-based paint. Velor rollers have one drawback - they collect little emulsion, which creates inconvenience during work.

When choosing a roller, you need to make sure that it does not deform when compressed, the pile holds tightly, and there are no visible seams on the surface. Otherwise, when doing the work, streaks will remain, and the fallen fibers will stick to the paint.

For convenience when painting, you will need a special painting kit. plastic container. Dipping a roller into a regular bucket is inconvenient.

Painting procedure:

Dilute the emulsion with water according to the attached instructions. For the first layer of water, add more.
Start applying water-based paint with a narrow brush in the corners and along the walls. This will prevent paint from getting on the walls when doing the main work.
It is better to pour emulsion into a paint bath in small portions.
Dip the roller into the mixture and roll it several times to ensure even distribution.
Continue painting the ceiling with a roller away from the window, moving across the direction of the light.
When the coating has been applied over the entire surface, the excess can be removed with a dry roller.
After the first layer has dried, apply a second one, along the direction of the sun's rays. Repainting The ceiling should be painted with water-based paint using a new roller. Only in this case is an ideal result possible.

If, after drying, unevenness is discovered, they can be removed by sanding the surface of the ceiling with a fine-grained sandpaper. How many layers of paint can you apply with a roller or brush? Most often, two are enough, but three can be done. It is important not to use electrical appliances or heaters to speed up drying.

Spray painting

Technology for painting the ceiling with water-based paint using a spray gun:

Dilute the emulsion, making sure there are no lumps. Otherwise they will clog the sprayer.
First, direct the jet to the side, since in the first few seconds the sprayer throws out too large a portion.
When the stream becomes uniform, start applying the water emulsion to the ceiling from a distance of 30-50 cm. The speed of movement should be approximately 5 s per 1 m. The stream should be directed strictly at an angle of 90 degrees.
Uniform application can be achieved by mentally dividing the ceiling into squares. Paint each one in turn, first along, then across.

How many coats of paint can you apply with a spray gun? Use a spray gun to apply three coats, allowing each to dry.

General rules

How to properly paint a ceiling with water-based paint? When choosing a method and during operation, you need to consider following rules painting:

It is recommended to use a spray gun to paint a plastered ceiling. It will provide a more even distribution than a roller. Primer application is mandatory.
For plasterboard ceilings, the emulsion should not be greatly diluted with water. Excess moisture can soak the top paper layer. In this case, it will be impossible to achieve a good result.
When applying the coloring composition, be sure to maintain uniformity and direction. Otherwise, the result may be areas that have a shade different from the main one. This is due to the fact that the intensity of light reflection depends on the thickness of the layer and the direction of application.
If, after applying a layer of water-based emulsion, multiple defects are found, then you must wait until it dries completely before attempting to repaint. Otherwise, attempts to correct it will lead to the opposite result. If applying a new layer does not solve the problem, then you need to remove the paint with sandpaper.

Due to their environmental safety, water-based emulsions are suitable for decorating even a child’s room. Sometimes it is necessary to quickly tidy up a room where a persistent pungent odor is unacceptable. It is in these cases that coloring compositions that do not require the use of conventional solvents are indispensable.

Painting the ceiling with water-based emulsion does not require the use of expensive tools. This work is easy to do yourself with paint, a roller and a brush. Even without special skills, it can be done well and beautifully. How to repaint a ceiling painted with water-based paint? To refresh it, you must first remove the old layer and carefully prepare the surface for applying a new one, and then paint it in the usual way.

Step-by-step instructions for painting the ceiling (1 video)

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 any cracks or chips that appear and fill them with finishing putty. Do this in small portions, trying to rub in deeply. 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.
