How to paint a ceiling after using water-based paint. How to paint a ceiling with water-based paint without streaks? Water emulsion - what it is like

It happens that when painting a ceiling, old paintwork removed, but sometimes this stage is skipped. If you do everything correctly, then even in this situation the result will be surprisingly good. After reading the article, you will learn how to paint over old paint.

Process Features

Painting the ceiling is not as difficult as it seems at first glance. As a rule, before this process, workers clean off old layer finishing. The fact is that a thick layer of old paint can show through and spoil appearance surfaces. If cracks appear on the ceiling, then the matter is completely hopeless - no matter how you paint them, they will still be visible. If repairs have not been carried out for a long time, then under a layer of old paint you may even find mold, which will negate all your attempts to update the surface.

If there are no such serious problems, then you can safely apply old paint a new layer of water-based acrylic. Take a close look at your ceiling. If you are satisfied with its appearance, and pieces of paint do not fall off, you can leave everything as it is.

Professionals also advise paying attention to the following: if you have painted the ceiling before water-based paint, then you're in luck. It's better than whitewash. Even if this type of paint begins to flake off and fall off in pieces, it may not be completely removed. You can easily limit yourself to superficial cleaning by removing loose pieces and cleaning the area around them. After this short work, you can safely apply a new coat of paint.

Paint selection

If you decide to paint the ceiling over the old layer of material, then you will have to face the question of choosing the appropriate option. For such work they are used different colors. Each type has its own advantages and a number of disadvantages.

Acrylic

Perhaps this type of paint is the most popular. It is good because it is highly resistant to all kinds of dirt and dries quickly. So you can safely use this material, for example, in the kitchen, where working with food is not always neat.

This paint also withstands high humidity well. If there is any contamination on the painted surface, it can be easily removed with a damp cloth or napkin without fear of the paint cracking.

Acrylic paint can be safely applied to the most different surfaces. It fits well on metal, wood, plastic, and even on already plastered substrates.

Painting with acrylic is also good because it perfectly hides minor surface imperfections. Textured paint capable of masking small cracks or places where pieces of the coating have already fallen off.

It is also pleasantly pleasing that such a coating dries quickly and retains its color for a long time. Even if you paint the ceiling in a room where it will constantly be exposed to sunlight, the paint will not fade or fade immediately. However, there is one caveat: when choosing this type of paint, remember that the color of the coating applied to the ceiling will be slightly different from the one you see on the package, because the material immediately darkens. This cannot be called such a big drawback, because there are a lot of colors, and you can always find exactly the shade that will suit you in the end.

With all these positive aspects, it is worth noting that the paint is not that expensive. You can purchase a kilogram of paint for about a thousand rubles. And it will be consumed quite slowly - to paint the ceiling in a medium-sized room you will need less packaging of material. On square meter About 100 g of paint is consumed.

Latex

There are several other types of paints that are suitable for ceilings. One of the most expensive options is latex. This paint is ideal for painting the ceiling over the old layer. The fact is that it perfectly masks defects and microcracks on any surface. You can easily wash or brush a ceiling painted with this material.

Silicant

Cracks (up to two millimeters) can also be masked by silicate paint. However, it is more expensive than most analogues.

In addition, it is also important to remember that silicate paints, as a rule, are not used in residential areas.

Water emulsion

Ceilings are also often painted with water-based paint. However, it should be used in dry rooms - for example, in living rooms or bedrooms. This type of coating does not tolerate high humidity and quickly becomes covered with cracks and dark spots (in the bathroom or even in the kitchen). The cost of water-dispersion paint is low, which is what makes it popular. In addition, it can be either matte or glossy, which is convenient for those who decorate their premises in a certain style and do not want to disturb the harmony in the room.

From these main types of paint for repainting the ceiling, you can choose any one. It can be dense and structured, oil-based, very light - it all depends on what your ceiling is and what your financial capabilities are.

Tools

Next stage is a matter of choosing the right tools. Most often, either a roller or wide brushes are used to paint the ceiling.

Tassels

Brushes of different sizes can be used both for painting the base and for joints and finishing elements. They are not very effective when painting the main part of the ceiling.

If you decide to paint such a large surface with brushes, then choose the widest ones. It is more convenient to paint the joints with walls, stucco molding and other decorative details with brushes.

Roller

It is much more convenient to paint the ceiling with a roller. Foam tools are used to paint the ceiling. The second most popular option is a roller with fabric base. The length of this tool for painting the ceiling can vary from five to thirty centimeters.

Spray gun

It is most effective to use a spray gun. However, not everyone prefers this option. The fact is that the spray gun is not only more expensive than all other devices, but they are also more difficult to use. If you are not a professional, then you will need to get used to the spray gun first.

How to dilute and calculate the quantity?

Having decided on the type of paint and tools, you can move on to the preparatory work. First you will need to dilute the required amount of material.

Paint consumption depends on how large your room is., the ceiling area is very important. As a rule, all necessary information, which will help you calculate the paint, is located on the packaging. Please review this information.

Having chosen water-based paint, you will see on the packaging that you should not dilute it. If the product you purchased has already thickened, you can slightly dilute it with water. Otherwise, just mix the paint, roll it onto the tray and start painting.

The preparation of others is not much different. ceiling paints. You will also need to add a little water to the acrylic mixture. It is best to use the product immediately after you have mixed it. It should not be allowed to harden.

Subtleties of application

Painting the ceiling without first removing the old layer of paint is a little different from the usual repair work. You will save a little time, because you will not have to completely remove the old layer and putty or prime the ceiling again. It will be enough to work on areas with cracks and remove falling pieces paint and varnish material. If the paint is peeling, it will need to be corrected, otherwise the surface of the ceiling will appear uneven and untidy.

When you have dealt with the most noticeable shortcomings, you will need to move on to the main work. The diluted paint should be poured into the tray - there should not be too much of it so that the remainder does not dry out or be thrown away.

Painting the ceiling starts from the very hard to reach places. Go over them with a narrow brush so that there are no gaps. After this, you can paint the entire surface. It is most convenient to work with a roller. This way you can quickly paint the ceiling over the old layer and paint over cracks and stains.

It is recommended to paint the ceiling in this way in several stages. The first layer may not be applied very carefully, but the second one will need to be worked on very well. You should start working with the second layer only after the first one has completely dried.

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? For this you will not need any great experience, nor 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? Water-based emulsion ceiling paint has the following characteristics that 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 compounds. 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 it seems taller, minor defects are invisible on it, 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 higher flow material.

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:

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

Painting the ceiling with water-based paint over the old one lime paint or whitewashing 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? The ceiling, cleared of old coating or a new one, is washed to remove grease and other types of contaminants. To do this, wash it with a detergent solution and then rinse it 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. On an industrial scale, airless spray technology is used. 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 is no visible seams. 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:

1. Dilute the emulsion with water according to the attached instructions. For the first layer of water, add more.
2. 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.
3. It is better to pour the emulsion into the paint bath in small portions.
4. Dip the roller into the mixture and roll it several times to ensure even distribution.
5. Continue painting the ceiling with a roller away from the window, moving across the direction of the light.
6. When the coating has been applied over the entire surface, the excess can be removed with a dry roller.
7. After the first layer has dried, apply the second along the direction sun rays. Repainting the ceiling with water-based paint should be done with 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:

1. Dilute the emulsion, making sure there are no lumps. Otherwise they will clog the sprayer.
2. First, direct the jet to the side, since in the first few seconds the sprayer throws out too large a portion.
3. 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.
4. 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.

Water-based emulsions thanks to environmental safety Suitable for decorating even a children'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.

The advantages of water-based coating are the absence of a pungent odor and toxic properties, the formation of a durable layer that allows cleaning, wiping and washing, the possibility of tinting - made it a popular material for decorating ceilings.

However, such painting, especially over a layer of old paint, has a number of features and mandatory preliminary operations.

Tools and materials - a complete list for all occasions

To carry out the necessary preparatory work and high-quality painting of the ceiling with any composition of the previous coating and surface condition, you will need:

Surface preparation

The even, monochromatic coating provided by water-based paint compositions does not hide, but, on the contrary, makes all surface defects, irregularities and stains more noticeable. Therefore, the ceiling must be carefully prepared before painting.

Removing the previous coating

First of all, you need to cover the floor and the remaining furniture in the room.

Then, if the ceiling was whitewashed, you should:

• Gradually wet the squares old whitewash sponge with warm soapy water;
• remove the soaked layer with a spatula, placing a tray in order to stain the floor less;
• finally wash off the previous coating with a sponge.

If there is old water-based paint on the ceiling, it will not be possible to wash it off. You should at least remove this coating where it has peeled off.

To identify and eliminate all such areas, you need to:

• moisten the ceiling generously with a roller;
• let the water soak in thoroughly;
• open the windows and doors and create a draft in the room;
• remove the old one with a spatula water-based coating from all areas where it was peeled off as a result of such a procedure.

Special processing

If there rust spots or dark streaks, they are covered with one of the following compositions:

• 3% hydrochloric acid;
• thick lime “milk” with 50 ml of denatured alcohol;
• 5% copper sulfate;
• 20 parts crushed lime with one part drying oil.

If there is black mold (a common occurrence in kitchens and bathrooms, and other damp areas), you need to follow these steps.

1. Strip the plaster down to the concrete. To reduce dust, it should be moistened first.
2. Handle concrete surface antiseptic primer. A budget alternative is a detergent containing chlorine, for example, “Belizna”.
3. Cover by problem area penetrating primer and re-plaster it.

Leveling the ceiling surface and priming it

If the ceiling is fairly level and even with side lighting there are no significant surface defects, the steps below are necessary.

1. Coat the ceiling with a penetrating primer. In this case, it is better to use a brush so as not to miss a single depression or irregularity.
2. After the primer has dried, remove any unevenness with finishing gypsum putty.
3. After 5-8 hours, level the putty areas, first with a coarse and then with a fine mesh grout.
4. Prime the leveled putty areas.

Primer of leveled putty areas

If formed gaps in the joints of the plates, A old plaster crumbles, then the algorithm will be slightly different.

1. Clean down to concrete using a spatula or hammer drill. There will be less dust if the surface is pre-moistened.
2. Coat with penetrating primer.
3. Re-plaster, checking the quality of work with a level and a steel meter. Cover the filled cracks in the joints with reinforcing mesh.
4. After a day, putty and finally level the surface with trowel mesh.

After leveling is completed, the surface is primed with water-based paint diluted with water.

Coloring

When purchasing a water-based paint composition for the ceiling, it is especially important to have a good understanding of the assortment.

Currently it is represented by five main types of products:

• with acrylic;
• with latex and acrylic;
• with silicone;
• with polyvinyl acetate;
• with silicates;
• with mineral supplements.

The cheapest water-based mixtures are with polyvinyl acetate, but the surface painted with them cannot be washed. The most expensive compositions are those with silicone - they fit well on plaster even without a primer, and the coating they form can withstand wet cleaning With detergents. Due to their good permeability to water vapor, they are ideal for kitchen and bathroom ceilings. Coatings that are average in price and durability are acrylic and latex acrylic paints; They are also the most in demand. Silicate compounds designed for painting concrete surfaces and brickwork, they are durable, but not moisture resistant.

Prices for acrylic paint

The main manufacturers of water-based paints entering the domestic market produce products that vary in both price and quality.

To choose the right water-based paint and purchase it in the right amount, you should carefully read the information text of the label. It must contain the following important parameters.

1. Purpose of paint listing the types of work.
2. Consumption per square meter– allows you to calculate required volume purchases. In this case, the paint must be purchased with some reserve, since the tone of different batches may differ noticeably.
3. Covering power– the ability to completely, without gaps, paint over a much darker base.
4. Abrasion resistance– the main indicator of durability and resistance to cleaning and washing.

In addition, you should read additional inscriptions, often in the smallest font.

1. "Recommended for use in dry areas." Such products are not suitable for either the bathroom or the kitchen.
2. “Indelible” or “Highly durable”. The painted surface can be washed exclusively with water without additional detergents.
3. “Abrasion-resistant”, “Dirt-repellent”. The coloring composition forms a layer that can withstand wet cleaning using detergents.

Having carefully selected a water-based composition that is suitable in terms of properties, manufacturer, price and purchased it in the required quantity, you can begin painting the prepared ceiling surface.

The process goes in the following order.

If the owner is faced with the task of updating an already painted surface, that means applying another layer of paint to it. How to do this so that the work does not turn out to be useless?

To paint the ceiling over old paint without any problems, you need to consider some points.

To avoid unpleasant situations when painting, you need to prepare the surface well. You cannot hope that by covering the ceiling with new paint you can hide all the defects. Everything is completely the opposite, a layer of paint will highlight everything: scratches, waves after painting, unevenness. First, it is important to carefully inspect the ceiling. If everything is fine, you need to start priming. But if there is paint on the surface that has peeled off or does not adhere well to the base, then all such paint must be removed. This can be done using sandpaper. After this, treat the surface with a thin layer of primer. After the primer has dried, we begin to renew the surface. If we see that the surface needs trimming, then we need to putty or even plaster the surface being treated. If this needs to be done, then priming must be carried out more intensively. You can even do this in several layers. This will ensure quality of work. It is best to apply the primer with a brush rather than a roller. This will ensure good penetration primers in uneven areas and depressions.

But if there is no paint on the ceiling, but old whitewash, then simply cleaning the surface and priming will not do. The entire applied layer of white must be completely removed.

After the surface is completely prepared for painting, you need to cover the walls and floor with film so that they remain clean. The temperature in the room when painting must comply with the instructions. Also, in order to paint the ceiling over old paint, you need to prepare the tool and the paint you have chosen. Both paint and tools must be good quality. Because the final result of the work done depends on it. Rollers and brushes will be needed in various sizes, and you can also purchase a telescopic extension and a paint cuvette for convenience.

How to paint a ceiling using old paint using technology so that there are no unpleasant moments later?

The first thing to do is paint the corners of the ceiling. This can be done with a brush or roller small size. Walk with these tools along the entire perimeter, in a strip of 5 centimeters. And the entire surface of the ceiling is then painted with a roller big size. For high-quality painting You need to apply at least two layers. The first layer should be applied starting from the window, across daylight. Pour a small amount of paint into the cuvette, immerse the roller in the paint, and then carefully roll it out on a special platform. This will remove all the excess paint, which will help distribute it evenly across the ceiling. There is no need to make sudden movements, smoothly move the roller along the ceiling, at the same time inspecting for the presence of unpainted areas. And if any are found, paint them over immediately. To paint the ceiling with a second layer of old paint, you need the same technology. The second layer is applied after careful checking to ensure that the first coating is of high quality and that it has completely dried. After painting the second layer, you need to make sure that no straight lines hit the ceiling. ultra-violet rays, eliminate drafts. Never try to speed up the drying of paint in any way, let it happen in a natural way. This way you can avoid the paint peeling off from the base. After each painting, ensure that the tool remains clean and free of paint residue.

What defects can occur when painting the ceiling?

Roller streaks may appear. They are formed when the roller is rolled out poorly. You can avoid this by re-rolling the roller over the painted base when there is no paint on the roller. This can also happen if the roller is not loaded correctly when painting. It is important to distribute the force applied to the tool so that the load is even.

It is also important that before you start working, you need to mix the paint well so that there are no stripes that will differ in shade.

If you follow the painting technology, there will never be a reason to look for flaws in the work done. And the result will pleasantly surprise you.

Today, the trend of painting surfaces is very common. But old surfaces are not always conducive to such actions. Many apartments still have whitewashed ceilings. Our article will tell you whether such ceilings can be painted with water-based paint and how.

Paint selection

Today, thanks to new technologies and finishing materials It is possible to paint the whitewashed ceiling. But for painting to be successful, it is necessary not only to properly prepare the surface, but also to choose the paint.

Most often, the ceiling surface is painted with water-based emulsion. But you can find several types of this paint in stores, which can make choosing difficult. So what paint should you paint the ceiling with? In order to choose the most suitable option, you need to know the features of each type of water-based paint. It comes in the following types:

• Polyvinyl acetate. It is characterized by low cost, as well as high hydrophobicity. This water-based paint can be used to cover surfaces only in dry rooms. In this case, washing such a surface is excluded.
• Compositions containing latex additives. The cost of such solutions will be the highest. But at the same time, with the help of such water-based paint you can create a smooth and resistant to various external influences coating.
• Acrylic. This species is characterized by high stability to erasing. Ceilings after treatment acrylic paint can be washed. Usage acrylic compositions allowed in any premises. Another advantage of this paint is its affordable cost.
• Slicone. Before applying this composition, no preliminary priming of the surface is required. This type of water-based paint is characterized by high vapor permeability. Therefore, treating ceilings with this paint is relevant in basements and bathroom.

As you can see, there are a wide variety of types of water-based emulsion. To choose the right composition, you must carefully read the instructions before purchasing. It is always shown on the side of the can. Thanks to the annotations, as well as the help of a consultant or seller, you can quickly choose a composition for painting the ceiling. In addition, from the annotation you can find out the material consumption per square meter and determine exactly how much paint you will need to carry out painting works.

Preparation

The ceiling must be prepared for treatment with water-based emulsion. Moreover, experts recommend that when painting with any composition, you carefully remove the old finish. Only in such a situation can the surface be painted with high quality.

Despite the fact that whitewash removal seems difficult, if you use correct methods surface preparation, it can be removed relatively easily.

Removing old coating from the ceiling occurs in two ways:

• dry method;
• wet method.

Let's look at both methods in more detail.

Dry method

In this situation, you will need the following tools:

• electric drill equipped with a brush attachment;
• grinder along with a grinding disc;
• sandpaper;
• Grinder.

The dry cleaning method, thanks to the use of the above tools, is carried out quite quickly. But it has several disadvantages, due to which it is used extremely rarely. The main disadvantage of this method is the huge amount of dust.

To carry out dry cleaning in a room, it must be carefully isolated. In this case it is necessary good ventilation rooms. Since a lot of dust will be generated during the processing of the ceiling surface, it is necessary to work only in personal protective equipment (goggles, respirator). After completing the work, all dust that has settled on the floor must be swept away. Then you need to rinse the floor thoroughly.

Wet method

The main advantage of this method is the minimum dust, which is much safer for human health. Although experts still recommend carrying out such surface preparation in a respirator. But wet method much longer in time.

To remove trim using this method, you will need the following tools:

• metal brush;
• sharpened small spatula;
• a roller having a medium length of pile;
• spray;
• container with water.

The wet method involves the following steps:

• First, you need to remove the maximum layer of whitewash by wetting the surface using a spray nozzle or a simple roller. Please note that you need to wet it small area to have time to wash off the whitewash before it dries completely.
• The solution should be applied generously, as the lime will actively absorb it.
• To increase the deoxidation of the whitewash, you need to add 5-6 tablespoons of regular soda and a few tablespoons of liquid soap to the water.
• After the solution has been applied, you need to wait a little (about half an hour).
• Then you can start removing the old finish with a putty knife.

If some areas of the old finish are not removed, you should not focus on them. You can return to them after processing the entire ceiling and clean them with sandpaper. It can be replaced with a brush for working with metal.

Before painting, you should try to remove the main layer of whitewash from the ceiling surface. In this case, you should not use very sharp objects (chisels, chisels, etc.), as they can lead to scratches and other defects in the base. This statement is especially important in a situation where under the whitewash there is a well-leveled layer of finishing putty.

If scratches and gouges are found on the ceiling, they should be covered with putty. After it dries, all resulting roughness must be rubbed off using sandpaper.

After the ceiling has become smooth, it is necessary to prime its surface before painting. A primer applied before painting will allow for greater adhesion and uniform distribution of the paint composition over the ceiling surface.

Painting

After the preparatory work has been carried out, painting can begin. To achieve maximum aesthetic effect, water-based paint must be applied in two layers.
