Painting with water-based paint - how not to spoil the walls and achieve an even coating?

Having decided to make repairs in a house or apartment, keep in mind that painting with water-based paint is not a difficult task, but it requires care. Painting the walls with a roller without streaks, and even the ceiling, may not work the first time, but you should not be afraid, use the tips and recommendations so that you do not have to repaint, and even more so call the master ...

How to prepare a room for painting?

Modern decoration of rooms and premises cannot be imagined without water-based paint, which can be in different shades, differ in application structure, etc. Before you start painting, you need to properly prepare the work surface, otherwise, stains, bumps, protruding spots and inclusions of various kinds will be provided. Mistakes can be avoided by observing the following rules:

• free the entire surface to be painted from old wallpaper. If the wallpaper does not peel off well, wet it with water and wait a bit, then try again to remove the residue;

• if the plane has been plastered, it is necessary to wait for complete drying (depending on the type and applied layer, the period is from 3 to 30 days). When using coarse-grained plaster, the walls are puttied first for maximum leveling and smoothness;

• to get an excellent result, water-based paint is applied only to clean, dry walls or ceilings. On the walls there should be no dust, particles of dirt or soot, spots of various origins. Very often, builders simply wash the surface with water with the addition of a small amount of detergents, but not abrasive ones;

• if the walls are new, only plastered, check if there are any marks left on the palms of the hands. If there is even a slight sediment, wipe the walls with a damp cloth and let dry;

The final step in preparing the walls for painting is priming, which is carried out on a clean and dry surface. In most cases, a polymeric primer is used, which is universal (for example, SNIEZKA ACRYL-PUTZ), which is specially made for the treatment of brick, lime, cement, plasterboard, gypsum, concrete surfaces.

The material is unique in that it increases the adhesion of the applied products (in our case, water emulsion) with the working surface (wall, ceiling, etc.). Thanks to the use of a primer, water-based paint lays down evenly, leaving no streaks even when working with a roller.

How to dilute emulsion paint and in what cases?

The first question that many people who want to make repairs on their own face is whether it is necessary to dilute the emulsion with water? It all depends on many factors, but the paint in the store is sold ready for use. Consider in what cases it is necessary to dilute water-based paint:

• when painting walls, ceilings with a water-based emulsion in two layers (it is desirable that the first coating be applied with a more liquid consistency). Here the question is not even in economy, but in the fact that it is easier to work;
• if the paint is old and thick, it is necessary to dilute it so that there are no stripes and visible lines from working with a roller;
• if paint residues from a previous repair are used;

To properly dilute the water emulsion, you need to take water no more than 10% of the paint volume. Take a large construction bucket, pour the paint. Then start adding water gradually, stirring constantly. To obtain a homogeneous consistency, a construction mixer or a drill with a special nozzle is used. When the uniformity of the composition is achieved, you can start painting the walls and ceiling.

If you want to change the color, use a tint. Here it is very important not to make a mistake with the amount of coloring matter, since the resulting color can be much different from the desired one. Remember, water-based paint diluted with color by hand, after drying, will have a less saturated shade than in liquid form. Therefore, all novice repairmen who decide to paint the walls and ceiling with their own hands are advised to check with the seller in what quantity and how to dilute the color scheme to obtain the desired result.

How to paint walls with a roller without streaks - instructions

If you don’t know how to properly paint the ceiling and walls with water-based paint, first carefully study the instructions, then proceed to painting:

➤ water-based painting begins with corners and joints. The first step is to paint the most distant corner, located from the doorway. Take a wide paint brush, dip halfway into the paint, wring out the excess a little and then paint a strip 30-50 cm wide around the entire perimeter of the ceiling. This approach will ensure uniform painting with a roller in the future, without visible stripes and streaks;

Advice: Distribute the first layer of water emulsion along the ceiling parallel to the sun's rays falling through the window, the second - across.

➤ all water-based painting work is done with a roller in three stages, regardless of the type of paint chosen. The very first painting should be done parallel to the sun's rays passing through the window opening. The second layer is applied perpendicular to the first. The final whitewash is done towards the window;

➤ The walls should be painted starting from the window, moving from top to bottom from the ceiling. Apply the strips vertically, with each next pass should slightly overlap the previous one;

➤ after painting the room with the first layer, it is necessary to wait until the paint dries, then proceed to the secondary whitewashing. Depending on the degree of staining and the properties of the coloring matter, the drying time of water-based paint is 8-12 hours.

Coloring technology:
➤ Pour the prepared paint into a wide tray, dip the roller and walk several times (3-4) along the rough wall for even distribution over the roller coat;

➤ Make the first pass as indicated in the instructions, while moving the roller from left to right, then change direction in the opposite direction;

➤ You can remove excess paint on the wall using the same roller, on which there is almost no coloring matter. It is necessary to walk on the surface so that excess paint is absorbed;

➤ Use a new roller at the last final whitewash to get an even, perfect water-based tone on the walls and ceiling;

➤ After painting with a water-based emulsion, the room should be closed until the surfaces are completely dry, avoiding drafts.

The demand and popularity of high-quality water-based paints are due to several undeniable advantages and ease of application.

In recent years, the category of water-based paints has been most often used, which has a very affordable cost.

5 advantages and 1 disadvantage of water-based paint

The demand and popularity of high-quality water-based paints are due to several undeniable advantages at once:

Pay attention to these points when choosing a paint

A significant number of different water-based paints can confuse any consumer. For painting walls and ceilings use only high quality paint and when choosing, pay close attention to the following features:

• paint composition;
• standard consumption;
• degree of viscosity;
• specific gravity indicator;
• expiration date and storage rules.

The optimal indicators characterizing a high-quality paint and varnish material are as follows:

• the composition should be represented by latex, filler, thickener and antiseptic additives;
• standard paint consumption for one paint layer is from 150 to 200 ml per square meter of surface;
• the optimal viscosity index when applying paint with a brush is 40-45 s. and no more than 20-25 - when using a paint sprayer;
• a good indicator of specific gravity is within 1.35.

The time for complete drying largely depends on the temperature regime and the level of humidity, the basic indicators of which are + 20 ° C and 65%. Any shifts from this level make it possible to obtain a drying time range from two hours to a day.

In addition, it is possible to choose the material depending on the polymer included in its composition. Water-based paints can be acrylic, silicone, silicate and mineral.

4 ways to remove old paint

The most moisture-resistant paints belong to the category of water-based paints for walls and ceilings, based on the use of polyvinyl acetate. Removing such paints is not difficult and it is enough to use a sponge, as well as any detergent.

Removing such paints is not difficult and it is enough to use a sponge, as well as any detergent.

To remove acrylic paints after wetting the surface, use a spatula or remove wet paint with an angle grinder.

One of the most effective means of removing old paint is pasting the surface to be cleaned with newspapers using standard wallpaper paste. After complete drying, newspapers with paint are removed quite easily. It is allowed to remove old paint with a chisel or gradually anneal all painted fragments with a building hair dryer.

However, the most modern and convenient way is to use a special chemical-based remover, which, after application, contributes to the destruction of all layers of paint. They can easily wash off the paint from the walls.

How do painters paint walls?

Immediately before starting painting work, the paint should be thoroughly mixed until smooth. If, according to the instructions, the paint used is supposed to be diluted with water, then this condition must be met, since such manipulations contribute to a more uniform distribution of the composition over the surface. In addition, if the desired shade does not match the tone of the purchased paint, then you should purchase a color scheme intended for use with water-based paints.

The surface to be painted should be as flat as possible. Regardless of whether the wall or ceiling is to be painted, all surfaces are puttied if necessary, and then treated with a high-quality primer.

To obtain the desired shade, a small amount of paint should be diluted, which should be applied to cardboard and dried. Only after these steps it will be possible to determine the correctness of the resulting color.

The surface to be painted should be as even as possible to paint the walls without streaks. Regardless of whether the wall or ceiling is to be painted, all surfaces are puttied if necessary, and then treated with a high-quality primer.

The best solution for wall painting

The room before painting should be as free as possible. The surface of the walls should be puttied and washed very thoroughly. All work is recommended to be carried out using a respirator, goggles and work gloves.

When painting already putty walls, it is advisable to apply paint in three layers, of which the first will be represented by primer. Wall painting on wallpaper can be done in only two layers. The process of phased painting occurs by applying parallel stripes in the direction from the window opening. The most effective way to paint the surface of the walls with the help of special equipment. The best option - using a spray gun. Such equipment is characterized by high productivity and has the ability to cover a large area for painting during operation.

If the manual method of painting the walls is used, then preference should be given to a wide brush with a size of at least ten centimeters. The bristles of such a brush are immersed in the paint by one third. All excess paint is removed by pressing the brush against the side of the container. Works are performed with short movements of vertical and horizontal direction and from top to bottom.

It is allowed to paint the walls with a roller, which allows you to perform the work most quickly and efficiently. Using a roller requires more coats of paint. In addition to the roller, a special tray is always used, which helps to evenly distribute the paint over the entire surface of the roller.

How to paint the ceiling as evenly as possible?

The most crucial moment when painting the ceiling surface is the most even application of paint. For this purpose, a high-quality wide roller is used, which must be completely covered with a layer of paint. Only after rolling the roller with paint on the construction tray you can apply paint on the ceiling surface.

A high-quality wide roller is used, which must be completely covered with a layer of paint. Only after rolling the paint roller over the construction tray can paint be applied to the ceiling surface.

The dominant principle of painting the ceiling surface is to apply water-based paint in extremely even parallel stripes. A characteristic difference is that each subsequent strip of paint overlaps the previous one by two or three centimeters.

It should be borne in mind that a high-quality painted ceiling can be obtained by applying at least three layers of paint, and the thinner each layer is, the more uniform and even the ceiling surface will be.

After the main area of ​​\u200b\u200bthe ceiling surface is painted with a roller, it is necessary to paint over with a thin brush all hard-to-reach places - joints and corners.

The most important thing when painting the ceiling with any type of water-based paint is to observe the direction of application of the material. The basic rule when applying the final coat of paint is the direction of all movements towards the main light source in the room. This painting principle helps to perfectly mask all minor defects and qualitatively level out any inhomogeneities characteristic of the coating structure, and most importantly, you can do it yourself with your own hands.

After the main area of ​​\u200b\u200bthe ceiling surface is painted with a roller, it is necessary to paint over with a thin brush all hard-to-reach places - joints and corners. It is possible to evaluate the quality of the completed painting only after the complete drying of the applied water-based paint.

Video instruction

When choosing a ceiling finish, painting is often preferred. This is an easy process that you can do yourself. The ideal option is to paint the walls and ceilings with water-based paint. Due to its composition, the material is safe to use and can be used even in children's rooms. We will talk about the types of water emulsion and methods of staining in this article.

Water-based paint for walls and ceilings

Coloring composition based on an aqueous emulsion is distinguished by purpose, cost and composition. Water-based paint for walls and ceilings is:

• acrylic water emulsion. This kind of coating can be used in any room. Water-based acrylic composition has properties such as wear resistance, moisture resistance. This is the most popular type among water emulsions;
• water-based composition with liquid glass additives. The coloring material is used for finishing plastered and concrete surfaces;
• polyvinyl acetate water emulsion considered the cheapest coloring materials. This variety can only be applied in dry rooms. Wet cleaning of the coating is excluded;
• silicone water-based finishing. The composition is used for plastered surfaces, and without preparatory work. Silicone coloring composition is able to protect walls or ceilings from mold fungi and other microorganisms. You can paint kitchen surfaces and use in bathrooms, due to good vapor permeability;
• acrylic latex water emulsion belongs to the most expensive finishing compositions. In the process of painting ceilings and walls, it gives a beautiful, smooth surface. With small cracks on the surface (up to 1 mm), it makes defects invisible. The latex-coated ceiling can be washed using gentle detergents.

High-quality painting of walls and ceilings with a coloring composition depends on the competent choice of the coloring composition.

The choice of water emulsion

To choose a water-based composition, you need to read the annotation of the product. Thus, it is not difficult to calculate the consumption of water-based paint for the ceiling per 1 m2. For example, if you need to apply one level of finish, you will need 200 ml of facing material. Material consumption depends on the type of work surface and the absorbency of the coloring composition.

It is important to pay attention to special water-based compositions for ceilings. The material has good adhesion and does not drip during staining.

Water emulsion happens:

• matte;
• glossy;
• semi-matt;
• semi-gloss.

So, the matte composition on the surface is able to visually increase the height of the ceiling, while hiding small surface defects. But, caring for a matte ceiling is difficult.

Caring for a ceiling painted with glossy water-based paint is easier. But, on such a ceiling, the most minor defects and irregularities will be noticeable.

The best choice can be called a semi-gloss or semi-gloss water-based emulsion.

It is better to purchase a water-based finish in hardware stores with a normal microclimate. At low temperatures, the texture of the coloring composition is violated and cannot be restored.

When choosing, it is also necessary to pay attention to the following characteristics of the water-based composition:

1. drying time of the facing composition. The standard time during which the paint dries is in a rather long interval - from 2.5 hours to a day. How quickly the paint dries depends on the temperature and humidity of the room, and the temperature and structure of the work surface;
2. paint viscosity. This parameter indicates the degree of dilution of the coloring material with water. If the coating is applied by roller or brush, then the viscosity of the composition should be 45 or 50 Stokes. If a spray gun is used, then the viscosity can be no more than 20 to 25 Stokes;
3. best before date usually 2 years from the date of manufacture if the product has been properly stored. You can not store water emulsion at sub-zero temperatures, but you must not allow the coloring composition to overheat.

When buying paint, you need to pay attention to what rooms the composition is intended to work in. There are special water emulsions for rooms with high humidity, or for work in rooms with a dry microclimate.

If you need paint for the bathroom or kitchen, then it is better to choose an emulsion containing antiseptic components. Such a composition can be applied without prior priming of the surface.

Having chosen the best option, it remains to find out how to paint the ceilings with a coloring emulsion with your own hands.

What to apply?

Before you start painting, you need to decide how to apply water-based paint to the ceiling. There are three options:

• brush;
• roller for painting;
• spray.

At home, we paint the ceiling with water-based paint without streaks, using a paint roller. If you use a brush, then visible strokes of paint will remain on the surface. The brush is used only for applying an aqueous emulsion in hard-to-reach places.

Not every roller is suitable for painting work using water-based paint. You need to choose a roller with an average pile length. A tool with a short fur coat absorbs too little coloring composition. As a result, you will often have to dip the roller in paint. A roller with a long fur coat, on the contrary, takes away an excessive amount of paint, which leads to a weighting of the tool and inconvenience in work.

When choosing a roller, you need to pay attention to how tightly the fur coat holds. To do this, firmly squeeze the pile and release. The pile of a good quality roller should not deform after compression. The pile should be inspected for visible seams that may leave streaks on the ceiling when painted. Pile should not leave marks on the ceiling during painting.

Sprayers for water-based materials are used on an industrial scale, in large rooms.

How to whitewash the ceiling with a water-based emulsion?

When you have decided on the choice of paint, you can start painting the surface. To whitewash the ceiling with a water-based emulsion, you must perform the following mandatory steps:

1. remove the old ceiling covering;
2. prepare the surface of the ceiling for painting;
3. if necessary, level the working surface and eliminate existing defects;
4. painting the prepared ceiling surface.

Let's take a closer look at how to paint the ceiling with a coloring agent with your own hands in stages.

Getting rid of the old ceiling covering

If you do not remove the old coating, then the new one will not be able to apply an even layer, and in any case it will begin to crumble over time.
Work on removing the old coating is carried out in protective seals and a respirator.

Remove the old layer of paint with a special wash as follows:

1. before proceeding with the preparatory work, you need to open the windows;
2. apply a layer of wash and wait until the old coating starts to bubble;
3. when the entire coating is cracked, it is removed with a spatula with gentle movements;
4. if the first time it is not possible to remove the entire old layer of paint, then it is necessary to use the wash again;
5. at the end of the removal of the old coating, the entire ceiling is polished with sandpaper.

If the ceiling has been whitewashed, then the whitewash must be removed before painting with water-based paint. Whitewashing is easily removed if the surface is abundantly moistened. You can use a roller for this purpose. During the removal of whitewash, you need to change the water several times. After soaking the ceiling with moisture, whitewash is removed without problems.

Surface preparation for painting

After removing the old coating from the ceiling, the entire surface is thoroughly washed to get rid of grease stains and other contaminants. First, the ceiling is washed with a detergent diluted with water, then simply rinsed with clean water.

It is possible that after washing off the old finish, defects formed on the ceiling surface. They need to be eliminated, but only after the final drying of the ceiling surface. Gaps and cracks are covered with putty. First, the cracks are widened with a spatula, cleaned, and a putty level is applied.

When the plastered surface dries, the treated areas are sanded with sandpaper. Dust must be removed with a wet sponge, then apply a primer coat. The primer is needed for better adhesion of the paint to the working coat, and as a protective layer against mold and other microorganisms. Thanks to the primer layer, the cost of water-based paint is noticeably reduced.

Primer levels are applied using a roller. It is better to take a tool with a short pile to eliminate ceiling streaks. The second primer level is applied only after the previous one has dried. The primer is applied in different directions.

Coloring

You can watch the video below for painting the ceiling with water-based paint with your own hands. Before performing painting work, it is necessary to dilute the material, bringing the composition to the desired consistency.

Typically, the aqueous emulsion has a thick consistency. With this composition, you can create relief compositions, but it is better to dilute the emulsion for coloring. Water is added to the material in small portions so as not to spoil the quality of the emulsion.

You can create different color shades yourself by mixing materials of different colors. For this purpose, any color you like is mixed with white paint, and brought to the desired consistency. When adding color, you need to thoroughly mix the composition until a homogeneous state.

Painting the ceiling with water-based paint is carried out in the following order:

1. dilute the paint with water. To apply the first layer of emulsion on the ceiling, more water is added;
2. diluted aqueous emulsion is poured into a special tray for painting work in a small amount;
3. first, water-based paint is applied in the corners using a brush. Brushes are also used for painting along the walls;
4. then the roller is lowered into a container with a coloring composition, and rolled several times for better absorption of the dye into a fur coat;
5. you need to start painting with a roller from the window opening, performing movements across natural light;
6. after applying the finish level with water-based paint, the excess composition is removed with a dry roller;
7. you need to wait until the first level of paint is completely dry, and then paint a second time. A second layer is applied along the direction of natural light.

Important: the second layer of emulsion is applied with a clean, new roller. Only if this rule is followed will it be possible to obtain a smooth, beautiful ceiling.

It happens that after the second layer of paint has dried, irregularities are found on the ceiling. In this case, the ceiling is polished with sandpaper with a fine-grained structure.

Usually two layers of water-based paint are applied to the ceiling. But, if two layers are not enough, then you can paint a third time.

Painting the ceiling with a water-based emulsion using a sprayer

Familiarize yourself with the method of applying water-based paint with a spray gun. Actions are performed in the following sequence:

1. diluting the emulsion with water, you need to make sure that there are no lumps in the composition. Lumps can clog the atomizer;
2. before spraying paint on the desired surface, test the action of the tool, directing the jet away from the ceiling. In the first seconds, the sprayer can throw out a saturated portion of paint;
3. it is possible to apply a water emulsion only when you are convinced of the uniformity of the jet;
4. the coloring emulsion is applied at a distance of 30 to 50 cm;
5. the approximate speed of paint spraying is 5 s per 1 m. Important: the jet is directed so that an angle of 90 degrees is observed.

To perform a uniform coating of the ceiling with a water-based coloring composition, you need to mentally divide the work surface into squares. Each such square must be painted in turn. The first layers are applied across, then longitudinally.

Working with a sprayer, they make three levels of water emulsion. Each level is sprayed only when the previous one dries.

When choosing a method of finishing with a water-based emulsion on the ceiling, and during painting work, you must adhere to the following recommendations:

• if the ceiling was plastered in preparation for painting, it is better to use an airbrush to apply paint. Thus, it will be possible to avoid stains on the ceiling surface;
• if the ceiling is plasterboard, then you need to dilute the paint with water very carefully. Paint abundantly diluted with water can soak a layer of drywall. As a result, additional repairs will be needed;
• in the process of applying a water-based emulsion, it is important to follow the direction of application of the composition indicated in the instructions. If you do not follow this rule, then individual sections will appear on the ceiling, differing in color and structure from the general coating;
• After completion of work on the ceiling, defects may appear. Do not panic, and immediately repaint the ceiling. Allow the surface to dry completely. If, after the paint has dried, the defects still remain noticeable, then this coating layer will have to be removed with sandpaper. Then a new layer of water-based emulsion is applied.

An aqueous emulsion can be used to cover the ceiling in a children's room. The composition of the paint is absolutely safe and non-toxic.

Water emulsion is also used in emergency situations when urgent repairs are needed. For example, you urgently need to paint the ceiling in a room where the pungent smell of the coloring composition is unacceptable. The water-based composition will be just a salvation, because solvents are not needed to dilute the paint.

Aqueous emulsions are popular due to the fact that additional expensive materials with tools are not needed in the process. Another advantage of using an emulsion is a fairly simple finishing method. Working with paint does not require special skills. Painting work can be done independently, using the simplest tools for painting. The main thing is to observe the phased implementation of staining.

Important: before painting work, the old coating must be removed. The coating will also be removed if the old paint or whitewash does not fly around. Only on the prepared ceiling can a fresh water-based composition be applied.

When starting to repair your home, whether it is a city apartment or a house in the countryside, everyone understands that the most difficult stage in this case will be finishing the ceiling. Modern companies specializing in apartment renovation offer a wide variety of options for this: ceiling tiles or wallpaper, stretch or suspended ceilings, etc. But not every householder can afford their services. Therefore, do-it-yourself is still relevant.

Until recently, such a type of ceiling decoration as was especially popular. But with the development of new repair technologies, this method is resorted to less and less. This is due to the fact that, despite its cheapness and the harmonious combination of a snow-white ceiling with any type of interior, many are not satisfied with the laboriousness of preparatory work. In addition, the whitewashed surface quickly becomes dirty and loses its attractive appearance.

Today, painting the ceiling with water-based paint continues to be one of the most popular ways to finish it. Unlike whitewash, the surface painted with it retains its aesthetic appearance for a longer time. In addition, it allows for quick and easy maintenance of the ceiling surface.

This is one of the cheapest repair options. In its composition, this paint is a suspension based on polymer particles and pigment substances dissolved in water. Its peculiarity lies in the fact that after application to the surface, intensive evaporation of water occurs, and the polymers form a coating with high resistance to moisture. Water-based paint is an environmentally friendly material that does not cause allergic reactions and negative effects on the human body.

The choice of water-based paint for the ceiling

If you decide that the best option for you is to paint the ceiling with your own hands using water-based paint, then you have a difficult task: to choose from a huge assortment of goods that would suit you in terms of price and quality. Today on the consumer market you can find emulsion paints with various additives:

1. acrylic,
2. acrylic with the addition of latex,
3. based on polyvinyl acetate,
4. with silicone or silicate base,
5. with mineral content.

The cheapest of them - polyvinyl acetate. But they can only be used in dry rooms. Ceilings painted with such paint cannot be washed.

Paints with the addition of latex- the most expensive. They have a number of advantages, such as the possibility of wet care using detergents, obtaining a smooth, beautiful surface, etc.

Acrylic water-based paints- the most sought after. They can be used in almost any room, they have increased resistance to abrasion during washing.

Silicate paints(liquid glass) are widely used for painting plastered, stone or concrete surfaces.

How to choose a water-based paint so that it has high strength characteristics, gives a beautiful surface after painting, etc. By the names of the paint offered for sale in jars, it is difficult to understand how one type differs from another, and what are their advantages. Moreover, the seller himself often tries to sell, first of all, the product that is more expensive, without thinking too much about its quality.

Read the label

Therefore, in order not to make a mistake with the choice, you should carefully read what is written in the annotation on the label of a can of water-based paint. In it, the manufacturer states:

• What type of work is it intended for?
• What is the consumption of paint per square meter (which is very important for determining the required amount),
• The degree of coverage (the ability of paint to cover a dark background with white, in the form of a continuous canvas),
• Its resistance to abrasion during wet cleaning, etc.

Be sure to pay attention to what is written in small print. Most often, the basic information about the technical characteristics of the paint is contained there. For example, if the annotation says that the paint has:

1. "High resistance to dry abrasion"- this means that the surface painted with such paint cannot be washed, but can only be wiped with a dry cloth or a vacuum cleaner can be used.
2. "Use in dry rooms with reduced operational load". This inscription indicates that the water-based emulsion is not suitable for painting kitchens, with a large amount of greasy fumes from cooked food, as well as in bathrooms where there is high humidity.
3. "High abrasion resistance, indelible"- the ceiling painted with such paint can be washed with water without the use of detergents.
4. "Stain-repellent, high abrasion resistance with intensive washing". This is the best type of water-based paint. Surfaces coated with this type of paint may be washed using gentle detergents.

Water-based paints can be glossy and semi-gloss, matte and semi-gloss. Their difference lies in the fact that matte paints slightly mask small surface defects and visually increase the height of the room. But they are difficult to wash. The surface covered with glossy paint is easier to clean, it is more resistant to abrasion, but small cracks and other flaws in the ceiling are noticeable on it. The best option is to choose a semi-gloss or semi-gloss paint.

Another important point. It is necessary to purchase water-based paint in a store that has an insulated warehouse. The fact is that when freezing, the structure of the paint is disturbed, which is no longer restored when it is thawed. And this means that the acquired paint has lost all its useful properties.

It is recommended to use water-based paint, the purpose of which is to paint the ceiling. It is perfectly distributed over the surface, practically does not drip, and has excellent adhesion.

Preparing the ceiling for painting

Before proceeding with painting the ceiling surface with water-based paint, it is necessary to carry out preparatory work. To begin with, it must be freed from whitewashing or layers of old paint. To get rid of chalk or lime whitewash, you will need to moisten it with plenty of water using a paint roller, and then scrape it off using a chisel or steel spatula. Finally, wash the ceiling with a sponge.

Removing the old layer of paint

To update the ceiling, painted with water-based paint, it will take much more time to carry out the preparatory work. This is due to the fact that the process of removing the previous painting is quite laborious, since the layers of old paint practically do not dissolve in water, and therefore it is not possible to scrape them off the ceiling completely. Most often, this work comes down to removing areas of peeling paint with a spatula.

To facilitate this not entirely pleasant work, you can use the following technique: moisten the old coating with plenty of water using a water spray or foam roller. Repeat this procedure twice with an interval of twenty minutes. The moisture should soak the old coating well. Then you need to create a draft by opening all doors and windows. A layer swollen with water forms blisters, and it will not be difficult to remove the old water-based paint with a spatula.

This work must be done very quickly so that the surface to be treated does not have time to dry. After that, it is necessary to treat stains from smudges and rust with a 5% solution of copper sulfate. If there are stubborn stains on the ceiling, use one of the following compounds:

1. a solution of hydrochloric acid, two or three percent concentration (carefully, trying to prevent the acid from getting on the skin, wipe the stains);
2. a solution of 20 parts of crushed lime, diluted with one part of drying oil,
3. a thick solution of water and lime with the addition of denatured alcohol (about 50 ml).

Any of the last two mixtures is applied for 10-15 minutes on pollution. Repeat until they are completely removed. Usually two treatments are enough.

If whitewashing was applied to your ceiling before the current repair - (there you will also find information on how to find out how the ceiling was painted earlier).

Ceiling leveling

As soon as the ceiling surface is completely cleaned, it is necessary to level it. A thin-layer putty is best suited for this, which has good adhesion properties, has excellent ductility and gives a smooth surface that can be easily sanded with fine-grained sandpaper. Apply putty to the ceiling using a spatula.

Often, the ceiling is leveled by applying a special whitewash putty on an oil-adhesive basis, which is evenly distributed over the surface with a roller, brush or spatula. Before this, it is necessary to repair all cracks and crevices in the ceiling, filling them with the prepared composition. In order for the putty to completely fill the gaps, they must be slightly expanded before applying it.

Primer

The next preparatory operation is the priming of the surface, which is performed with the same paint. It is applied in a thin layer. She is allowed to dry well so that the putty does not come off.

The main stage of painting

Painting tools

To perform high-quality painting of the ceiling with paint based on an aqueous emulsion, you will need:

1. paint brush for painting butt joints between the wall and ceiling, as well as corners;
2. narrow brush for correction;
3. fur, long pile roller,
4. paint bath,
5. ribbed surface for uniform distribution of paint over the surface of the roller.

Staining rules

just as with whitewashing with chalk, it is better to apply the first layer of paint parallel to the rays of light from the window, and the second - parallel to the window frame

Many do not know how to paint the ceiling with water-based paint correctly. In most cases, they do not take into account during the execution of painting work, the direction of the light flux and many other nuances. Therefore, the painted surface is uneven, with stripes from the passage of a brush or roller, with lighter or darker spots. To prevent this from happening to you, follow the following rules.

• It is always necessary to start painting from the corners and joints between the wall and the ceiling. In this case, the farthest corner relative to the front door is painted first. To do this, a wide paint brush is wetted halfway in the paint, then squeezed lightly to remove the excess. A passage is made along the entire perimeter, with a width of 3 to 5 cm. Due to this, with further painting with a roller, the junction of the ceiling and the walls, as well as the corners, will not be damaged.
• The main whitewashing of the ceiling with water-based paint is carried out with a roller. It is applied in three passes, no matter what type of paint is selected. In this case, the very first pass of paint is carried out parallel to the rays of light falling from the window. The second in a perpendicular direction to it. The latter - should always be directed towards the window.
• Each subsequent staining is carried out only on a well-dried previous layer. This takes 8 to 12 hours.

Coloring technology

1. In a bath filled with paint, moisten the roller, and run three or four times over a rough surface. This will allow the paint to spread evenly over the roller.
2. Make the first pass on the ceiling section. Starting from the corner on the left side of the wall opposite the window.
3. Move the roller from left to right. Then change direction. In this case, it is necessary to ensure that the paint lays down in an even layer, without visible transitions. You can move the roller and W-shaped movements.
4. The following technique will help to remove excess applied paint: when there is no more paint left on the roller, pass it over the painted surface. He will absorb all the surplus.
5. In the process of performing painting work, use a directed bright beam of light to check the quality of the painting.
6. The use of a new roller during the last painting will allow a uniform surface to be obtained.
7. Until the paint is completely dry, drafts are not allowed in the room. It is advisable to protect the painted surface from direct sunlight. This will help prevent stains. Do not try to dry the painted surface with electrical appliances.

Features of painting a plastered surface

The ceiling, on which the plaster is applied, can be painted using a special spray gun or a conventional vacuum cleaner. They give a high-quality, uniform distribution of paint on the plastered ceiling surface. At the same time, it lays down in a thin, even layer. It is best to paint with an airbrush on a primer already made with a roller or brush.

Painting walls with water-based paint remains one of the simplest and most affordable types of finishes. The variety of colors and excellent results allow it to maintain its popularity. The application technology is very simple, you can handle it yourself without the involvement of specialists. At the same time, the finished surface fits perfectly into any design, creating a modern interior.

Comparing water-based paint with other types of finishes, the following advantages can be distinguished:

• it will take about 2 hours to dry;
• contains only safe, non-toxic components;
• does not have an unpleasant odor;
• you can get any color or shade.

The main components of the paint include latex, filler, thickener and antiseptic. It can be applied with a roller, brush or spray gun. For do-it-yourself work, the viscosity of the composition should be no more than 45 s, and when using an airbrush - 25 s. Material consumption is on average up to 200 ml per m2. When choosing it in the store, you also need to pay attention to the expiration date, storage conditions. If the paint is frozen, then the structure is broken, it cannot be used.

Types of water-based paint

Despite the name “water-based paint” traditionally used by everyone, there are several types of this material. The main component, according to which the paint is divided into separate types, is a polymer - acrylic, silicone, silicate, mineral. It affects the convenience of working with the composition, its performance characteristics.

Acrylic paint is made from acrylic resin. The latex included in it improves the hiding power of the composition, smoothes out the slightest cracks. Acrylic paint is recommended for painting surfaces exposed to water. It fits perfectly on plaster, wood, brick, glass, suitable for painting walls and ceilings. A double coat of acrylic paint can repair fairly large damage.

Using silicone resins, a silicone compound is obtained. Its purchase will be expensive, but the result will make up for the costs a hundredfold. Even one layer of it is able to eliminate cracks up to 2 mm wide. The coating has vapor permeability, does not become infected with a fungus. It can be washed without fear of spoiling.

Silicate paint is obtained from a mixture of water, pigments and liquid glass.

It creates a vapor and breathable layer, evenly applied to the base. It is distinguished by increased resistance to weathering, durability. But in damp rooms it is better not to use it.

Mineral paint is recommended for work on concrete or cement surfaces. It contains cement or slaked lime, which significantly improve its water resistance. The material is suitable for painting ceilings and walls. The disadvantages of the composition include its fragility.

Color selection

An interesting fact: when talking about a water emulsion, they always emphasize its ability to transform a room, fit into any design. The base color of the composition is white. By adding a pigment of one or more shades, the composition is given the desired shade. You can do it yourself or use a computer selection.

For tinting, you need to use a color designed for water-based emulsion. It is produced from acrylic dispersion in three formats: powder, emulsion, paste. Liquid color is considered the most convenient to use. It mixes well with the base composition, creates a homogeneous mass. The finished paint fits well on any surface - plaster, brick, wood. Advantages of ready-made colors:

• allow you to get shades that are not on sale;
• have high resistance to fading;
• easy to use by hand.

The variety of possible shades is amazing. But it should be noted that it is almost impossible to repeat the desired color combination on your own. Therefore, when doing repairs with your own hands, it is better to immediately dilute the right amount of paint. When wet and dry, the shade is slightly different. The coating will look different in different lighting, applied to a different base. Therefore, before painting the entire wall, it is better to try on an inconspicuous area. Of course, a slight variation in shade will not spoil the design of the room, but in large areas it can be noticeable.

How to mix color with paint?

When painting with your own hands, you need to properly dilute the color scheme. This should be done shortly before use. The maximum amount of color should not exceed 30 ml per 1 liter, that is, no more than 3%. A large amount of pigment can affect the quality of the paint. In order not to make a mistake with the shade, you can use this method:

• prepare 3-4 clean small containers of a known volume;
• pour paint into each and add a different number of drops of color;
• apply a strip of each type to the surface;
• choose the result you like.

Then you need to recalculate the amount of paint and drops for the desired volume. After that, you can proceed to breeding. You will need a clean container, into which no more than 20% of paint is poured. The calculated volume of color is added to it and mixed thoroughly. The finished mixture is gradually poured into the main container with paint.

Surface preparation

Before painting, the base must be freed from layers of old finishes - paint, wallpaper, whitewash. The easiest way to remove the whitewash, it is simply washed off with water. The wallpaper can be pre-wetted slightly, and then gently pry with a spatula and remove. Harder to remove old paint. It is not soaked with water, it will have to be scraped off or a special wash should be used. The surface should then be inspected for damage, mold or rust. If necessary, stains should be treated with copper sulphate.

The next step is alignment. Even small bumps or cracks under a layer of paint will take on an ugly look, spoiling the most expensive design. Therefore, they need to get rid of. Putty works great with this. Depending on the condition of the surface, only finishing or starting and finishing putties are used.

First, the surface is primed and left to dry. The starting putty contains a coarse-grained filler, so it effectively eliminates fairly large cracks and pits. The dried layer of putty is treated with a coarse-grained sandpaper. As a result, traces of a spatula and irregularities are eliminated. The coating is again covered with soil.

The finish putty is very fine in structure. It is applied in a thin layer, allowed to dry and rubbed with a fine sandpaper. To check the quality of work, use the light from the lamp. It is directed at an angle to the wall, revealing the slightest deviations. The result of the performed manipulations is an ideal surface on which the paint will lie in an even layer.

To protect parts of the walls or ceiling that will not be painted, stick a strip of masking tape on them. The same strip can be glued along the floor. At the end of the work, it is easily removed, and the surface under it remains clean. If you need to close a large area, then you can use a strip of polyethylene, securing it with tape.

Foundation Stage

For work you will need:

• regular brush for painting corners and joints;
• narrow brush for correcting hard-to-reach places;
• roller with a long pile;
• special bath with a ribbed surface area.

In order for the result to please with its beauty and accuracy, it is necessary to take into account several nuances. Painting should start from the corner located on the opposite side from the entrance to the room. First, take a wide brush, moisten it in paint, wring it out slightly. A strip of 3-5 cm is made around the perimeter of the room. This will help make the joints and corners neat.

For further work, use a roller. Staining is carried out in three stages:

• apply the first strip parallel to the rays of light falling from the window, continue staining in the same direction;
• then make movements in a perpendicular direction;
• the third strip is always directed to the window, and so the staining is completed.

Each stage is performed after the previous one has dried. On average, it takes up to 12 hours. In order for the paint to be evenly distributed over the roller, they are carried out several times along the corrugated part of the bath. Roller movements on the surface can be straight or zigzag. The next strip is applied with a slight overlap on the previous one. Having finished painting, it is necessary to protect the room from drafts, direct rays of the sun. Drying should not be artificially accelerated.

How to make Venetian plaster with regular paint?

The most expensive types of finishes include Venetian plaster. It is distinguished by a complex execution technology, but the result is incomparable with anything. This design looks elegant, unusual and expensive. Using ordinary water-based paint, acrylic varnish, roller, sponge, brush and sandpaper, you can imitate a "Venetian" at an affordable price.

First, a strip by strip is covered with a layer of water-based emulsion on a previously leveled base - fiberboard, drywall, plastered brick or any other smooth surface. When the water emulsion dries, proceed to the creation of a "marble" pattern. It is preliminary recommended to work out strokes on a piece of cardboard.

To give the acrylic mixture the desired shade, color is added to it. Its color must match the color of the marble. For application, use a sponge, making light stamping movements. On a fresh acrylic base, you can make "cracks" with a solid rod. After the varnish has dried, the pattern is passed over with a soft brush, slightly shading the borders. Then they change the color of the varnish and apply it again to the base.

The finished coating must be given time to dry, then it is sanded with light movements. The resulting dust is not brushed off, but covered with a colorless varnish. Such actions are performed twice. This creates the inherent depth and brilliance of marble.
