Painting the walls in the bathroom is the most common and demanded type of budget finishing for this room. Unlike other options, correctly selected paint is able to cope optimally with aggressive conditions of high humidity.

Today, there are many ways to decorate the walls in the bathroom: ceramic tiles, mosaics, plastic panels, decorative plaster, and more. However, there are times when painting is considered the most optimal and profitable solution.

The reason for this may be: a high degree of condensation in the room, a modest family budget, renovations in a rented apartment, the implementation of bold design solutions such as interior graffiti.

Based on this, the main advantages of painting walls in a bathroom are:

Profitability

Ease of application... Painting is a quick and easy procedure that does not require special skills or preparation.

Diverse color palette of paints... Allows you to bring to life original fantasies and design ideas.

In addition, high-quality paint on the walls of the bathroom, when applied correctly, guarantees that the room will meet sanitary and hygienic standards, as well as provide ease of cleaning, a certain moisture insulation.

In addition to the many advantages of using coloring compositions, there are also negative factors that are taken into account when choosing a finish for the bathroom walls:

A small room with a weak ventilation system always leads to the formation of condensation, which destroys the structure of the paint and varnish material, thereby reducing its service life.

There is no desire and time for frequent cleaning: painted walls must be wiped after each bath.

There is a high risk of damage to the coating with sharp objects: the finish will lose its attractive appearance, and the space between the wall and the paint layer will become a place for moisture accumulation.

In addition, it should be noted that the walls of the bathroom must be perfectly flat for painting. This is not easy to achieve, and you will have to work a lot on high-quality putty and grout.

In recent years, the building materials market has been pleasing with a wide range of paints and varnishes. All coloring compositions differ from each other in basis, texture, manufacturer, pricing policy and other indicators.

By the type of base, paints and varnishes that can be used to decorate the walls in the bathroom are:

Oil

Alkyd... Varnish-based compositions. They are durable, practical and have excellent decorative features. However, it is worth considering that alkyd enamel is quite flammable and toxic.

Aquatic... Suspensions that are ideal for painting walls in the bathroom. Unlike previous types, water-borne paints have good moisture and UV resistance. Also, after application, they dry quickly and allow the walls to "breathe".

Today, the most demanded coatings for bathroom walls are water-dispersion paints, which are produced using the latest technologies. They consist of an aqueous dispersion and solid polymers. Thanks to this composition, the paint is absolutely non-toxic and safe for health.

The most common types of bathroom paints and varnishes:

Water-based paint

Acrylic paint... An ultramodern coating based on a water-dispersion emulsion. It is composed of water, acrylic polymers, marble chips and titanium dioxide. Such paints create a vapor-permeable film that protects the wall from moisture and pathogenic microflora. Acrylic compound can be used to paint walls in the bathroom, made of plasterboard, concrete or brick. The coating dries quickly and is easy to clean. When creating an original interior design, white paint can be tinted in any other color.

Silicate paint... It is an emulsion based on liquid glass, pigments, hardeners, fillers and other components. Before you start painting the walls, you must treat them with an aqueous alkaline solution with the addition of potassium. The silicate formulation has excellent resistance to moisture, high temperatures and direct UV rays. The coating is evenly applied to surfaces such as brick, stone, plaster, ceramics and concrete.

Silicone paint... A relatively new material for painting walls in the bathroom with your own hands, which consists of emulsified silicone resins. It perfectly combines the best properties of acrylic and latex paints. The main advantage of such a coloring composition is its dirt-repellent properties. Thanks to this, the walls in the bathroom do not require frequent wet cleaning. Silicone paint bridges cracks well, thereby giving the surface an attractive appearance. The composition is applied in several layers on a primed base.

Latex paint... Water-based dispersion coating based on latex acrylate. Such material is absolutely environmentally friendly, waterproof and breathable. It is resistant to detergents and therefore has a long service life. Latex paint is suitable for finishing concrete, plaster, brick and plastered walls, as well as for painting chipboard and fiberglass wallpaper. An ideal solution for walls with small defects is a matte finish.

Eyes run up from the abundance of colors and varieties of paints. However, choosing the first shade you like for decorating the walls in the bathroom is frivolous. To choose the right paint color, you must rely on the following criteria:

If the bathroom has a small area, then it is better to avoid buying coloring compositions in dark tones. The best option would be light shades, which will help to visually increase the size of the room. They are white, peach, pink, green and blue. They have a calming and relaxing effect.

If you have a small bathroom, you should refuse to completely paint the walls. The best option would be to delimit the walls. At the same time, painting can be combined with tiles or plastic panels.

In a large and spacious bathroom, do not limit yourself to pastel colors. Feel free to improvise and use vibrant colors.

When choosing a paint, its texture is of great importance. It is glossy and matte.To add shine and saturation to the interior of the room, it is recommended to use glossy paint. However, it is worth considering that such a coating will look perfect only on perfectly aligned walls.

Matt paint is more versatile. She has the ability to hide minor wall defects. This texture perfectly complements the design of any interior.

In order for the application of the paint and varnish material to be fast and of high quality, it is necessary to stock up on special tools and materials:

Roller

Painting brush... Perfect for painting joints, borders and small details. In terms of size, a brush for finishing works can be narrow and wide. It is worth considering that painting with such a painting tool increases the consumption of paints and varnishes several times.

Aerosol can with coloring composition or spray bottle... Provide the fastest possible painting process. It will consist in spraying paint over the finishing surface.

Also, to paint the walls in the bathroom, you will need: scotch tape, fine-grained sandpaper, film, gloves, a respirator and glasses, scissors.

The surface of the walls for painting in the bathroom must be perfectly smooth and even. Holes, cracks, spots and swollen bumps in the initial finish can all affect the quality and aesthetics of the overall finish. To avoid such troubles, it is necessary to carry out a thorough preparation of the surface.

The phased preparation of the walls in the bathroom for painting looks like this:

Remove the old cladding layer. In order to remove paint, whitewash, wallpaper or plaster from the surface, sandpaper, a spatula, a grinder and a solvent are perfect.

We remove dust and material residues. After removing the old cladding, we wash the walls and humidify the air in the room. For this, a spray bottle and warm water are used.

We level and putty the walls. With the help of the finishing compound of the putty, we carefully cover up holes, cracks and other flaws. Since the bathroom is a place with a high humidity index, it is better to use a waterproof acrylic putty for finishing.

We sand the walls. To give the base a smooth and even surface of the wall, we carefully grind it with fine-grained emery paper.

We cover the walls with a primer. To prepare the walls for painting, it is necessary to treat them with several layers of primer. In this case, it is better to resort to using a latex adhesive containing antibacterial components.

Also, after preparing the walls, make sure that all surfaces in the room except the walls are protected. To protect objects and coatings from the ingress of paints and varnishes, it is necessary to close all borders with film or newspaper and paste over with tape.

Only after you have made sure that the walls are perfectly smooth can you start the painting process. Painting will have a positive result if you follow the step-by-step instructions:

First of all, we decide on the painting tool. If the walls are uneven, it is better to use a brush, which allows you to apply the paint in a thicker layer, which will help to hide minor surface defects.

We carry out coating on the wall in 2-3 stages. For the first layer, dilute the paint with water by about 10%.When it dries up, we make the subsequent application of the composition without first diluting it.

We remove excess paint and varnish material. To do this, it is better to use a special tray with a ribbed surface. It squeezes out excess paint before applying to the wall.

If you are planning to decorate the walls, then you can resort to using geometric shapes, shapes, lines. To implement design ideas, you will need masking tape.

For a bathroom, tiles are most often chosen as a finishing material for walls and floors. However, wall paint is a good alternative. In this case, various solutions can be used with their own parameters and properties. Painting the walls in the bathroom is easy, so often the owners of residential buildings do the work with their own hands. Due to the affordable cost of paint, you don't need to spend a lot of money on decorating a room. But for this it is important to carefully understand the features of the procedure in order to avoid any mistakes. Although the method is considered budgetary, you should not purchase the cheapest paint; you will not be able to get a high-quality work result with it.

Painting the walls in the bathroom with your own hands is considered a simple process, but for this you first need to correctly choose the coloring composition itself. With its help, a moisture-resistant and durable coating should be created. Antibacterial additives must be present in the product, because the bathroom is considered an ideal room for the development of microorganisms.

How to paint the walls in the bathroom? For this, paints are most often chosen:

water-based - it is divided into acrylic and silicone, as well as latex and paint created using PVA;
alkyd - is considered a universal and easy-to-use composition. It is used for outdoor work, and also provides effective protection of metal surfaces from the corrosion process. Therefore, if there are any metal objects in the bathroom, then they can be effectively covered with an alkyd solution. It is moisture resistant, and it dries quickly when oxidized with oxygen. It is simple to use it, and at the same time there are no ugly stains that spoil the appearance of the coating. However, the alkyd solution has an unpleasant odor, so it is not advisable to use it to completely color the bathroom;
chlorinated rubber - most often used in the pool, since with its help a coating is obtained that does not allow moisture to pass through;
oil - in Soviet times, it was most often used to decorate the bathroom. It dries up in a day and has an unpleasant and pungent odor. It is usually only used when the finishing budget is limited. The coating will crack over time and is considered difficult to remove.

Most often, walls in a bathroom are painted with water-based paint, available in several varieties. You can choose one of the options:

acrylic paint - has an affordable price and the ability to perfectly envelop the base. Well suited for painting bathroom walls;
latex, after drying, forms a special film that protects the base not only from moisture, but also from dirt;
a composition based on PVA is considered one of the most affordable, but its characteristics are not suitable for a bathroom, since it is used only in dry rooms, as well as for painting ceilings;
the silicone solution is highly vapor and moisture resistant. Most often chosen for house facades.

For the bathroom, water-dispersion paint, formed on the basis of acrylic or latex, is most often chosen.It is necessary not only to decide on the material, but also on what color to paint the walls in the room.

If you have a small bathroom, then it is recommended to choose light shades of finishes for it. This contributes to a visual increase in space. Additionally, it is taken into account what color plumbing fixtures and other furniture in the room have.

Large rooms make great use of the various contrasts to create unique and unusual finishes. In this case, the ideas of the homeowners are beautifully embodied. However, streaks are clearly visible on dark surfaces, so you will have to devote a lot of time to cleaning the room.

Bathroom walls can be painted with matte or glossy compounds. Glossy coatings are attractive and bright, but such paint is used exclusively for perfectly flat surfaces. Matt paints are considered universal and help to hide minor defects and irregularities on the substrate. However, coatings made of them are characterized by low resistance to mechanical stress. Often, relief compositions are chosen for the bathroom, allowing you to make an unusual structure on the walls.

Bathroom walls are painted using standard and available tools:

a brush that creates even stripes. It tightly covers the base, but it is believed that due to its use, material consumption increases. For work, it is necessary to choose high-quality brushes, since it is not allowed for the pile to fall out of them. If you plan to paint the entire room, then working with a brush will be laborious and time-consuming, so this tool is usually used for hard-to-reach areas, which include corners;
the roller is used to create a thin layer, so the amount of material used is saved. However, irregularities and angles are difficult to handle with this tool. If water-based paint is chosen for staining, then it is best to choose rollers with a felt surface. The size of the tool depends entirely on the width of the surface;
The spray gun is considered a specialized equipment that allows you to quickly and efficiently paint any wall. It ensures an even distribution of the composition on the base, however, after each use of this instrument, it is important to thoroughly rinse it;
tray for paint.

Typically, homeowners use rollers and brushes. It is impractical to buy an expensive spray bottle for one painting process. However, it can be rented from specialized stores.

Painting a bathroom is not difficult if you study the entire procedure for this work well. It breaks down into several distinct stages.

Initially, the walls in the bathroom are prepared for painting, which involves the complete elimination of the old coating. Most often, you have to deal with an old coating of paint or tiles. For each individual case, a different method of material removal is used:

paint - it is removed with a hammer or chisel. The blows ensure that the old coating is broken off. Also, the chemical method is often used, which involves the use of a special paint stripper. The work process is simple, as the brush is applied to the walls, after which you have to wait about half an hour. The paint will begin to swell, so it can be easily removed with a hard spatula. If the paint has eaten heavily, then the procedure for applying the composition will have to be repeated. It is only necessary to work with the products in protective gloves and in a ventilated room. Also, the thermal method is often used to remove paint, which involves heating the old coating. This will lead to the fact that the material on the wall becomes soft, therefore it can be easily removed with a spatula;
tile - the old tile covering is also removed with different tools due to mechanical action. This process is considered time-consuming and difficult, and it is also important to be careful so as not to be damaged by the sharp remnants of the tile.

As soon as the old coating has been removed, the leveling and preparation of the base begins.

Walls for painting in bathrooms must be leveled before painting. A paint coating will in no way hide various imperfections, transitions and irregularities on the base, so leveling it is an indispensable process to obtain a high-quality and beautiful coating.

All recesses on the surface are filled with high-quality putty, and a special agent is selected, intended for use in rooms with a high humidity index.

A putty based on latex or acrylic is considered optimal. It is applied with a wide spatula, after which it is evenly distributed over the base, which ensures complete filling of all grooves and irregularities.

If there are significant transitions on the base, then often it is not possible to cope with them with putty. In this case, you have to initially plaster the walls along the lighthouses, and only then work with putty.

After creating a layer of putty, you must wait until it is completely dry. This usually occurs within two days, however, the moisture level in the room affects the speed of drying of the material.

The dried layer of putty is carefully sanded, for which it is allowed to use a grinder or sandpaper. In the first case, a little time is spent on work, and a high result is guaranteed, and in the second case, you will have to make a lot of effort to get a flat surface in the bathroom with your own hands. If sanding is carried out using a sander, then it is advisable to carry out the work using an industrial vacuum cleaner in order to immediately remove the resulting dust.

After sanding, the walls are covered with a high-quality primer, and it is advisable to apply the composition in three layers. This will ensure a reduction in paint consumption, as it will not be strongly absorbed into the walls of the room. It is advisable to choose a special primer that contains antibacterial components. This will protect the room from mold or mildew.

Then you can paint the walls in the bathroom, and this process will be simple due to the advance and correct preparation of the base. To create a high-quality and durable finish, it is recommended to cover the base with at least two coats of paint.

Make sure that there are no drafts and that the base is completely dry after all previous steps. It is advisable that the room temperature is set to at least 10 degrees.

How to paint the walls in the bathroom? For this, important rules are taken into account:

one layer is applied at a time, so it is not allowed to break the work into several stages;
if you plan to use paint not only for walls, but also for the ceiling, then the horizontal base is initially painted, and then the vertical surfaces;
if it is planned to obtain an unusual and original color of the coating, then the paint is mixed with a pre-selected color scheme, after which the resulting mixture is thoroughly mixed;
the first layer is applied, and it is desirable to apply it in horizontal stripes, for which rollers are used;
hard-to-reach areas are treated with a suitable brush;
it is important to monitor the uniform distribution of the composition so that there is no color transition;
after the first layer has dried, the second is applied, and it is desirable to apply paint with vertical strokes;
if you plan to create a drawing on the walls using a combination of different shades, then the painted surface is covered with paper tape.

After work, the painted walls in the bathroom should be left to dry for a few hours. If any streaks, color unevenness or other problems are found, then another layer of material is applied.

The resulting coating must be protected from dirt. Water does not harm it in any way, however, cleaning from contamination should be carried out only with a damp cloth. Do not use abrasive substances or hard brushes, as they will easily ruin the coating.

Bathroom wall painting is considered a great alternative to standard tiles or plastic panels. For this room, special coloring compositions are selected that perfectly cope with high humidity and temperature changes. It is quite simple to work with them, therefore, the decoration of the premises is often carried out on their own. This allows you to save on wages for hired specialists, as well as on the purchase of expensive tiles. In this case, a coating is obtained that is distinguished by high quality, interesting appearance and long service life. If you choose washable paints at all, then the surface can be cleaned with water and sponges, and often with cleaning agents.

Starting the renovation of a bathroom, you have to take into account the cost of materials that will go to all the necessary materials from the family budget. Manufacturers offer many beautiful options for tiles and panels.Only a cheaper decorative coating than paint cannot be found, no matter how expensive it is.This raises the question of how to paint a bathroom with your own hands in order to achieve maximum savings. Knowing how much the services of the craftsmen cost, it is better to decide to make the repair yourself. They say beginners always do better.Each material has directions on how to use it. This allows a person who has never been involved in repairs to quickly navigate the features of a particular paint, plaster, putty. For a bathroom, as related to rooms with high humidity, it is necessary to choose materials marked "moisture resistant". In the second place in the choice of paint will be its color, in the first - the features of the material."Waterproof" - having seen such a mark, it is better to leave this material on the store shelf. It is more suitable for external work, and in the bathroom it will create a greenhouse effect - condensation will accumulate on the surface of the walls. We can immediately make a reservation that this type of finishing materials includes oil paints. Despite the fact that builders still often use them to decorate the walls of bathrooms in new buildings, it is better to choose latex, acrylic or water-based ones.The color of modern paints is brighter, and there are much more shades. Bathroom design will only benefit from this. The choice of oil paint in most cases is based on a lower cost over latex and acrylic.There is no definite answer to the question of what paint to use in the bathroom, the main thing is that the coating is even and lasts a long time. All materials have strengths and weaknesses. When thinking about a design followed by drawing, it is better to choose acrylic. For a thin, bright finish, latex is more suitable. For DIY repairs, both paints are good.How much paint to take for bathroom renovation can be determined by the instructions on the bank. Knowing the footage of the room, and multiplying it by the height of the painting, you get the result - how many meters you need to paint. Comparing with the data on the packaging, it will be possible to decide whether one container is enough or several are required. It remains only to choose the color of the paint.Acrylic waterproof is presented in a large assortment, which will allow you to create a completely original design using pure saturated color. True, you can work with this type of paint only on a perfectly aligned canvas of walls.It is not very expensive, and when compared with ceramic tiles, its price is generally ridiculous.

If the battery in the bathroom is replaced with a shiny heated towel rail, then one problem disappears by itself.If there is still a metal battery in the bathroom, then it is necessary to choose a contrasting one or the same shade as that used for the walls, otherwise the design may suffer. Do not paint batteries with acrylic paint, like other metal surfaces.For walls, this material is ideal, especially when creating textured patterns or color transitions created with an almost dry brush. You can use the white color of the walls as a background, which you get when using a decorative primer. And you can combine two contrasting or shades of acrylic paint with the same marking. The first layer is applied with a roller, creating an even surface, on the dry surface, using a brush, on which there is very little paint, apply arbitrary strokes.When working with acrylic paint, you can let your imagination run wild. Textured bumps can be obtained by applying the material to the walls with a roller with a long soft nap, which is very easy to do with your own hands, you just need to control that the paint is on the roller in sufficient quantity, but does not drain when the roller touches the wall. The material consumption will be high, but the result is worth it.Acrylic dries quickly, which allows you to not only apply a layer of paint to the wall, but also decorate it with a stencil pattern in one day.Not everyone can make a stencil with their own hands, but with the help of a rubber roller, everyone can apply a drawing on the wall. A roller with a suitable pattern can be bought in the same department as a regular paint roller.Latex paint perfectly creates a protective coating of walls, preventing the formation of fungus, just like any moisture-resistant paint. In contrast to moisture-proof, it has the advantage that it allows steam to pass through, which reduces the formation of drops. With a small temperature difference between water and air, with a low formation of steam, condensation does not form at all, which makes washing the walls more rare due to the absence of water drips.In direct contact with water, the latex coating does not lose its appearance and does not deteriorate. Small cracks in the wall will not become an obstacle for painting, without preliminary filler, due to the thickness and ductility of the paint.Water-based paint - excellent moisture resistant material. Most often, on store shelves, you can find a water emulsion that has a pure white color or with a tint of ivory. To cover the walls in the bathroom, it can be used with the exception of those areas that are located directly behind the sink, shower, bath. Penetrating foam, toothpaste and other non-hazardous detergents can damage the paint coating.There can be no question of washing away soap stains from the surface of the walls with the help of abrasive agents. This paint is cheaper than the others, but the complexity of care makes its use not convenient.A whitewashed ceiling is best suited to painted walls. This is not a tribute to fashion or tradition, the correct choice of hygroscopic materials can reduce the humidity in the bathroom. Chalk perfectly absorbs excess moisture, preventing excessive condensation.Chalk ceiling is better than water-based. The larger the area covered with chalk, the less water on the floor and wall. This explains the tradition of painting the walls of the bathroom with paint only up to half, and whitewashing the upper part of the walls.At this stage, the name "whitewash" is not entirely relevant, because what color to paint the ceiling, everyone decides for himself, choosing not only the design, but the color scheme. Color schemes will help to create a tone or shade.The color scheme is cheap, it can be easily added to chalk and paint. It belongs to the type of water-soluble, which significantly expands the range of its use.In practice, they can be given the desired shade of any paint, the main thing is not to be mistaken in the amount of color for the container of the dye. If there is only white paint in the house, you can create the required color with your own hands by adding color to it. The design of the walls will only benefit from this, and adding more or less color scheme will have to be decided by the home master himself.

Painted bathroom

Among the majority of consumers, it was associated with cheap and not entirely substandard repairs. But in recent years, paints and varnishes have again become in demand. In fact, they have found a second birth thanks to European designers. It is in Europe that there is a real boom in this type of finish. Especially when it comes to renovating large bathrooms.

Painting the walls in the bathroom, as a way of modern decoration, has the following undoubted advantages:

it is easy to do it yourself, with a minimum of experience in finishing work;
the cost of most paints is quite acceptable;
it makes it possible for a person to show their creative talents (it is easy to choose any color of the coating).

In addition, painted surfaces are easy to maintain. Walls can be easily washed with a sponge or rag using conventional detergents.

The disadvantages of painting walls include the following facts:

relatively low durability of paint and varnish coatings (for example, if we compare them with finishing a bathroom with ceramic tiles);
the need for careful preparation of walls for painting;
high susceptibility of painted surfaces to mechanical stress (paint is easily damaged by impact).

Experts advise against painting walls in small bathrooms or in cases where there is no well-functioning ventilation system in the room. In such situations, it is better to give preference to other methods of decoration.

Materials for painting walls in a room for receiving water procedures must necessarily have antibacterial protection. In a humid environment, active growth of fungi and a variety of microorganisms is observed. Only paints and varnishes with special additives are capable of resisting their development. Most often, the walls in the bathroom are decorated with the following paints:

Latex and acrylic. These water-dispersible compounds protect walls from the appearance of bacteria, protect surfaces well from physical influences, and are very durable. An important point! Latex paints make it possible to obtain a matte surface of the walls, on which stains from dried water drops are practically invisible.
Water-based. Traditional material for dyeing, used for a very long time. Water-based paints are easy to apply with your own hands, they do not emit unpleasant aromas, and are considered completely harmless and environmentally friendly. But the surfaces painted with them require special care. The water emulsion is afraid of most detergents. Therefore, the walls on which it is applied should be washed very carefully, with a minimum of chemicals.
Oil. These compositions are characterized by a pungent odor, they dry for a long time on the treated surface.But oil paint remarkably resists moisture, mechanical shock and high temperatures. At the same time, it is inexpensive.
Chlorinated rubber. Paints that are very popular in European countries. We have recently started selling them. Such formulations have many operational advantages, but their cost is objectively high.

The choice of paint for the bathroom

Also, for decorating walls in the bathroom, universal alkyd enamels are often used. Formally, they are intended for outdoor work, but they are also suitable for finishing premises with special operating conditions. Such compositions give a good appearance to surfaces, when used, they do not leave streaks on the walls, they dry quickly. And most importantly, alkyd enamels perfectly protect walls from moisture.

If you want paints and varnishes to adhere well to the walls, you need to properly prepare the surfaces for painting. You will need to remove the old coating with your own hands, carefully align the walls, rid them of cracks and cracks, and then prime.

The used paint is removed with a grinder equipped with a flexible disk, a perforator and a chisel, sandpaper, a spatula, and a scraper. Craftsmen also often use special attachments for an electric drill, which allow them to get rid of old coatings in the most inconvenient places, a chisel and a hammer drill. Professionals recommend using diamond nozzles on a sander to remove unnecessary finishes. But not every person has such a power tool.

After cleaning the walls in the bathroom, they need to be checked for mold and mildew and, if necessary, treat problem areas with an antiseptic, bleach or copper sulfate. Then wipe the surfaces with a damp cloth and proceed to putty. For these purposes, putty compounds are used for indoor work.

Note! The putty you choose should have a high moisture resistance. From this point of view, compositions based on latex or acrylic are ideal.

After filling the cracks, you need to wait until the putty is dry, and then remove all small irregularities from the wall with a grinder or sandpaper. The next step is surface treatment with a primer. It is applied in several layers. Buy primers that are antibacterial. Then the walls will not subsequently be affected by the fungus. The best primer for treating bathroom surfaces is a latex-based primer.

Before starting staining, it is advisable to dry the bathroom with an electric heater. This procedure is necessary, since even well-prepared concrete walls absorb moisture.

Self-painting walls

Painting is carried out directly with a spray gun, roller or paint brush. The specific tool is up to you. However, remember that:

It is difficult to handle corners and small irregularities on the walls with a roller. But its use allows you to save paint due to the fact that it is applied in a thin layer to the surface.
When using a brush, the consumption of paint and varnish material will be large. But the surface texture will be denser.
It is most convenient to work with a spray gun. True, not all home craftsmen have it. And after painting, it is required to disassemble, rinse (and very thoroughly) every part of this device. This is not to everyone's liking.

In everyday life, it is easiest to paint the walls with a brush and roller. This combined method will provide an ideal finishing result.

The painting operation itself is performed in two layers as follows:

Prepare (according to the manufacturer's instructions) the paint.

Apply the first coat. Better to do it with a brush. It makes it possible to process the joints and corners of the walls as efficiently as possible. In addition, the brush guarantees a dense layer of paint, which allows you to mask small imperfections in leveling and sanding the surface.

Wait for the painted walls to dry.

Apply a second layer. Now with a roller. If you are using a water-based emulsion, the villi of this tool should be made of acrylic. For latex and oil applications, choose a polyamide bristle roller.
