How to paint walls with water-based paint: from selection to application. How to paint walls with water-based paint: choose which water-based paint is better to paint the walls yourself How to paint the walls in a room with water-based paint

If you have to paint the walls with water-based paint, the design, photos, ideas and videos from our article will help you understand the intricacies of this process and do it yourself. On the one hand, everything is easier than it seems, but only if you are well prepared.

The choice of water emulsion for walls

The composition of water-based paints is different. Some are intended only for indoor use, and even then they are unstable, and the walls painted with them quickly lose their attractive appearance. Others are designed for outdoor work and the walls after painting are able to maintain the desired quality for years. In this regard, the choice of colors is determined by what is expected of it.

Water is used as the basis for any water emulsion. The substance consists of polymeric or mineral particles. When stained, water evaporates, and these particles are able to form a film. Such coloring compositions can be as follows:

Mineral water emulsion . The technology of their manufacture involves the presence of lime or white cement. A good property is excellent grip on almost any surface. But the fact that they quickly burn out can be attributed to the disadvantages. They are easy to damage, and when touched, they can be wiped off. Their price is low, but they are still not very popular.
silicate paint . The composition of such paints is characterized by the presence of liquid glass. It is this that gives such compositions a special resistance to external factors. At the same time, the wall acquires excellent vapor permeability, and lasts for almost 10 years after painting.
Acrylic based paint . The paint lays evenly on the surface, even capable of tightening small cracks. It will hide such flaws if the preparation of the wall is not done well enough. In the event that the paint does not contain additives, it has a high hygroscopicity. By the way, because of this, you can only work with it in dry rooms. If latex is added to such paint, then it acquires water-repellent properties. This makes it possible to use it in rooms with excessive moisture release. Its disadvantage is the low ability to pass steam. In this case, the surface may be covered with condensate. The price of such paints is average and today they are considered to be the best of the entire range of products of this kind.
Silicone water emulsion . Such paints are new and such products have appeared on the market quite recently. When painting, a rather dense film is created. It has the ability to tighten deep cracks. The positive point is that such paints are able to pass steam. The disadvantages include their high cost.

Picking the right ingredients is only half the battle. We still need to decide on the manufacturer. There are several options here. It is better to give preference to well-known brands. It is better to pay more than to repaint later.

When making a choice, you should pay attention to indicators related to the volume and consumption of paint. The dimensional value of the flow rate is g/m2. For different colors, it can differ significantly. For example, expensive paints have a small consumption. Comparing the volume of the room with the volume and consumption of paint, it is easy to calculate how much of this will be needed.

Wall preparation

Before starting work, the walls must be prepared without fail. It is desirable to achieve a perfectly flat surface of the wall. The surface must be puttied or covered with wallpaper intended for painting. If the wall was previously painted with oil paint or whitewashed, they cannot be covered with a water-based emulsion. The surface is pre-cleaned.

Paint removal

To remove the old water emulsion, the wall should be wetted with hot water. This can be done with a roller. After 5 minutes, these actions must be repeated. After the second pass, the coating usually begins to swell, after which it can be easily removed with a spatula. Some difficult areas are wetted again.

We close up defects and putty

When working with water emulsions, you must immediately get rid of the idea that such paint will hide defects, on the contrary, it will only emphasize them. The only exception is silicone emulsion. She can still hide small flaws on the surface of the walls. But it is better to prepare the wall as expected.

First putty notches and cracks. After that, they are primed. Before puttying, the crack is artificially expanded and everything that can fall off in the future is removed. Then everything must be carefully cleaned and smoothed out all the bumps.

Padding

The choice of primer depends on what kind of paint will be used in the future. If acrylic paint will be used, then it is necessary to take an acrylic primer. The primer is applied with a roller.

Priming will provide a circumstance in which the paint will hold better. In addition, the consumption of the paint itself is also reduced. The primer closes the pores, as a result of which the area of the absorbent surface decreases.

Technology and coloring rules

In the basic version, the color of the water emulsion is white. It can be easily changed if you add a certain color. Currently, more than 200 shades can be obtained in this way.

Tinting can be carried out directly in the store, where it will be done in a special machine, or you can buy the necessary pigment and do it yourself. The difference is that self-cooking is approximate and the color is determined "by eye", and in the machine this is done through a special program.

The process of mixing paint with pigment is carried out at a time. In the future, it will be problematic to prepare the same shade, even for a car. Therefore, it is necessary to prepare the composition with some margin.

If the color is selected independently, then at first the paint is slightly diluted with water. Usually initially it has a thick consistency. Then color is gradually added to it in a thin stream. This can be done manually using a wooden spatula, but it is better to do this with a drill with a special nozzle.

The tool must run at the lowest possible speed. Everything is thoroughly mixed until the desired shade is obtained. You can't start painting right away. You have to wait a bit - the foam should settle.

What is the best roller to use?

Rollers differ in the material for their manufacture.

Foam rubber . The price of such products is negligible. Their disadvantage is that they are able to absorb too much paint. As a result, bubbles may form on the walls. The wall after painting will be rough. It is better if there is a roller of the highest density. True, it is not easy to find such a product for sale.
Velours . Rare item. Velor has a slight ability to absorb, therefore, when painting a wall, it will have to be dipped in paint more often than rollers made from other materials. But the paint lays down very evenly.
Pile . Such a roller would be the best option. The length of the pile affects the thickness of the paint layer. Often rollers are made of natural fur. Such products have a significant service life. A fleecy roller is best suited when working with wallpaper for painting. But it is better not to use furry products, too much splashing.

Painting process

Before painting the plinth must be removed. If this is not the case, then masking tape should be glued on them. This fully applies to window sills and platbands. Masking tape will also be required to mark the boundaries of the painting on the wall. If the ceiling is already painted, then sticking adhesive tape on it would be useful. Otherwise, it can just get dirty.

There is one nuance here. The adhesive tape must be removed immediately after painting. Otherwise, the paint on it can dry out. If this happens, it will be very problematic to tear it off.

The paint is poured into the paint tray. The roller is supplied with a handle of sufficient length. This is necessary in order to be able to paint under the very ceiling. What to attach to the roller, everyone decides for himself. It can serve as a wooden stick or a plastic tube.

To start the painting process, choose one of the corners. It is necessary to pass the corner itself not with a roller, but with the help of a brush. One of the corners under the ceiling base is selected. Then the roller is dipped into the coloring composition, squeezed out on the pallet platform and smoothly driven up and down the wall. The upper border of the painting will be the ceiling. At the same time, several step into the already painted places. This technique eliminates the possibility of the formation of boundaries between the painted areas.

The time for which water-based paint is able to "grab" is 10 - 15 minutes. Therefore, all work is carried out very quickly.

The second corner begins to be painted over when there is a distance as wide as a roller to it. If the adjoining wall is painted immediately, then this corner can also be painted.

If the walls were previously puttied, then the paint is applied in three layers. Each subsequent layer is started only when the previous layer is completely dry.

The drying time of the paint is usually indicated on the can and is usually from 2 to 4 hours. But if the application of a water emulsion is supposed to be applied to the wallpaper for painting, then one layer is quite enough.

Now you know how to paint walls with water-based paint. Design, photos, ideas and videos should help you decide on all the questions to do everything yourself, but if you have any doubts, feel free to ask in the comments.

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 range 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:

acrylic,
acrylic with the addition of latex,
based on polyvinyl acetate,
with silicone or silicate base,
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:

"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.
"Use in dry rooms with reduced operational load". This inscription indicates that the water 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.
"High abrasion resistance, indelible"- the ceiling painted with such paint can be washed with water without the use of detergents.
"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:

a solution of hydrochloric acid, two or three percent concentration (carefully, trying to prevent the acid from getting on the skin, wipe the stains);
a solution of 20 parts of crushed lime, diluted with one part of drying oil,
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 what the ceiling was painted with 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 is 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:

paint brush for painting butt joints between the wall and ceiling, as well as corners;
narrow brush for correction;
fur, long pile roller,
paint bath,
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 around 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

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.
Make the first pass on the ceiling section. Starting from the corner on the left side of the wall opposite the window.
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.
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.
In the process of performing painting work, use a directed bright beam of light to check the quality of the painting.
The use of a new roller during the last painting will allow a uniform surface to be obtained.
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.

Applying paints and varnishes with a roller is a popular solution for finishing work. Specialized rollers for different paint formulations and surfaces are an example of a combination of simplicity and ease of use with ease of learning even by non-professional painters.

Painting walls with a roller: the choice of tools and features of the process

Roller - for painting. It simplifies the process of applying paint, speeds up the processing of large surfaces, and reduces the consumption of the coloring composition.

Roller work allows you to control the thickness of the layer and correct the unevenness of the application, while the paint is not yet dry.

The result of using the tool is a uniform coating.

Wall painting with a roller: a simple solution

The choice in favor of the roller pays off with the numerous advantages of working with it:

ease of distribution of the coloring matter;
lack of accumulations of paint that form smears, stains, smudges;
ease of manipulation due to the reciprocating rotation of the mechanism;
the possibility of using stencil and texture nozzles;
less chance of lint or bristles falling out compared to a brush.

Painting technique: existing options

When using a roller, attention should be paid to the quality of painting: a lack of paint on the tool can lead to the formation of unpainted spots that are difficult to notice during the work process. Such "bald spots" will have to be duplicated with an additional layer of paint, since dotted strokes will stand out from the overall uniformity of the coating.

A common method of roller work is the “letter W” technique: vertical stripes slightly overlap each other at the junction, allowing you to quickly paint a large area. The speed of staining in this way does not allow the paint to dry before the end of the work, which makes the resulting layer even, visually complete.

Painting the "letter W" requires room for manipulation, so it's best to do it in an empty room. In this case, the long handle of the roller gives special convenience.

Another way to avoid gaps and stripes is the “squares” technique. It consists in the conditional division of the wall into squares at the corners, which are painted alternately, and then connected into a single coating with horizontal stripes. This method depends on the illumination of the room and takes into account the direction of light from the window.

Painting with "squares" requires speed to avoid premature drying, so it is more often used by professionals. Fans also need to monitor the degree of drying of the paint in order to prevent coating on an already dry place.

Roller selection

The whole variety of rollers is based on the difference in their purposes (use for various surfaces, areas of the surface to be painted).

Size

Rollers are divided into three types according to their size.

Mini - designed for local work in small areas, in corners, for stencils. Also, rubber-based mini-rollers are used to strengthen the seams, increasing the adhesion of the coating to the wall.
Midi - medium size rollers, convenient for most painting activities. They are used when painting walls, floors, ceilings, and the correct selection of a fur coat allows you to work with all types of paint.
Maxi - large rollers, when using which it is difficult to track the uniformity of application and the absence of gaps. The use of maxi-rollers was found in priming work on large areas, as well as in the creation of a primary coating layer, which will be covered by subsequent finishing.

A variety of roller sizes is also found in the range of highly specialized rollers for uneven surfaces, aggressive paint compounds, or bitumen.

Foam rubber

Highly absorbent and suitable for painting most surfaces. The foam nozzle is chosen for water-based or adhesive-based paints and for varnishes.

It is impossible to work with a foam roller with water-based and oil compositions, since during operation they will destroy the structure of the material, which will lead to the formation of lumps on the paint.

Velours

Gives a smooth surface, used for ceilings or finishing layer on walls. Velor is suitable for the use of water-based and oil paints, however, it does not absorb solutions well, which is why you often have to pick up paint from a pallet.

Polyamide

Synthetic roller coats are universal: they are suitable for all types, they are not afraid of aggressive solvents, they absorb and release paint. In addition, polyamide rollers are easy to clean after painting, so they last for a long time.

Fur

Fur rollers differ in the degree of fluffiness and give excellent results even on uneven walls due to the length of the pile. Fur coats (artificial or natural) are used for water-dispersion, oil, alkyd compounds, they are distinguished by spray-free coating. Fur rollers help to create a uniform layer of paint even on surfaces with cracks, drops, chips. Suitable for painting large areas.

How to paint the walls correctly

Roller selection also depends on the type of coating to be applied. Each paint has features, the timely consideration of which will make the work with a roller high-quality and effective.

water-based paint

The best choice would be rollers coated with velor or pile.

Velor fur coats have a weak absorbent power, so they are better suited for small sizes of painted surfaces.

Pile rollers are an expensive option (especially those made from natural materials), but they have a number of advantages:

the ability to select the length of the pile to create layers of a certain thickness (for a thin pile - a short pile, for a thick one - a long one);
used for uniform painting of the wall and for decorative finishes;
long-term operation;
the presence of a special elongated pile for porous, rough surfaces.

enamel

Enamel paint is used to obtain a glossy surface, so the requirements are placed on the initial smoothness of the wall and on the material of the roller, which should not leave particles or air bubbles. Creating a glossy finish requires a large natural wool roller - this will allow you to have time to apply the enamel without drying stripes.

silicate paint

The peculiarity of applying silicate paint with a roller is that the material of the fur coat must gain and give the same from strip to strip, otherwise the difference in the thickness of the layers will be noticeable visually. For silicate compositions, synthetic rollers and special pallets are selected with a place for rolling in the form of a grid, which removes unnecessary excess.

Other types of paints

The modern variety of types of paints and varnishes can create difficulties when choosing a roller. In this case, it is better to contact a consultant in the store, who will select the tool, taking into account the characteristics of the paint. In addition, it is worth paying attention to the instructions for use, where compositions suitable for the roller should appear. So, for painting latex walls, a roller with a minimum synthetic pile is suitable, and when applying alkyd mixtures, you can not do without a brush, which should also be suitable for marking.

To avoid defective areas on the surface to be painted, it is necessary to follow a number of mandatory instructions for working with the roller.

The fur coat should be checked for the quality of the pile even in the store (a quality tool is when, when held with the palm of your hand, the structure takes on its original form, with a slight twitch, the hairs of the fur coat do not separate from the roller).
The metal frame of the roller should not have extraneous stains of old paint, rust; the rotation mechanism must be smooth, free.
Although the roller allows you to quickly paint the surface, when working with a specific coloring composition, it is necessary to calculate the exact time of its drying. Divorces and stripes are most often formed at the junctions of different layers, so compliance with the technologies for paints, varnishes, liquid wallpaper will help to avoid poor-quality results.

Thus, the use of a roller is the best option for combining price and quality: the tool does not require large financial costs, is suitable for all surfaces and is easy to use.

Finishing the interior of apartments or suburban areas is not a simple construction process. It requires a special approach and attention. Today, people often try to do repairs on their own in order to save money, and sometimes in order to learn something new and try their hand. This fact is especially relevant for homeowners who are engaged in painting residential premises. In construction and decoration, water-based paint is most often used. With a relatively affordable price, their quality is compared with high-quality oil paints. Water-based paints are a very popular, promising and high-quality repair material. This article describes in detail all the pros and cons, specifications, types of water-based paint.

Advantages and disadvantages of water-based paint

Water-based paint has a number of significant advantages.

First, it dries pretty quickly. Sometimes it only takes a couple of hours to dry.

Secondly, the paint is absolutely harmless and completely safe for the environment and human health. During painting work, there is no need to urgently leave the premises.

Thirdly, the paint does not have a sharp specific smell, which generally persists for 2-3 weeks after finishing work is completed.

Fourthly, the composition of the paint can be given almost any color, while adding special pigments. Building stores usually sell a colorless tone, and a catalog with pigments is offered for it. The consumer can choose the shade he likes and on the spot the specialist will give the water-based paint the desired shade.

Fifth, the process of applying the paint is quite simple, and the paint tools are easy to clean after use.

The disadvantages of water-based paint are much less than the advantages. The main disadvantage is that the dyeing process can only be carried out at a temperature of + 5 ° C.

Technical characteristics of water-based paint

Before you buy a water-based paint, you need to pay attention to its technical characteristics, which include:

Composition;
Consumption;
Viscosity;
Specific gravity;
Storage conditions;
Best before date.

The composition of the paint includes: latex, filler, thickener and antiseptic.

Consumption of water-based paint - for 1 layer is approximately 150-200 ml / m2. The required number of coats depends on the absorbency of the substrate.

Viscosity is an indicator that determines the degree of dilution of the coloring mixture with water. Viscosity is measured with a viscometer and should be about 40-45 s. when using a coloring brush, 20-25 when applied with a paint sprayer.

The specific gravity is about 1.35 kg/l.

Drying time directly depends on the temperature and humidity of the air, it can vary from 2 to 24 hours. The optimum temperature when painting a room with water-based paint is + 20 ° C, and humidity - 65%.

Types of water-based paints

Today, depending on the polymer that is part of the paint, there are four main types of water-based paints, namely:

Acrylic;
Silicone;
silicate;
Mineral.

Acrylic water-based paints

This type of paint is currently the most common. Acrylic resins serve as the main component in the composition of the paint, and therefore the water-based paint received its name.

Very often latex is added to the composition. Such a combination of components allows acrylic water-based paints to actively resist water. This suggests that the painted coating can be washed with water without problems, without fear that the paint will become unusable or even washed off. Manufacturers in the characteristics of the paint very often indicate that it can withstand up to five thousand washes with water. A double coat of this latex-filled acrylic paint can mask surface cracks up to 1mm thick. Acrylic water-based paint, the price of which depends on many factors, fits very well on the surface of wood, glass, concrete, brick, plaster, concrete, as well as on metal that has been primed in advance.

A striking example of such a coloring agent is water-based paint VAC. It does not have a specific, unpleasant smell, it is safe, dries quickly, and working with paint is very easy.

Silicone water-based paints

In silicone paints, by analogy with acrylic, silicone resins are present in the composition.

Such paint, despite the rather high cost, is perfect for all mineral coatings and can easily paint over cracks up to 2 mm wide. Silicone water-based paints belong to the class of a vapor-permeable coating. This quality allows the paint to be used on damp, as well as moisture-prone surfaces. With such paint, you can forget about the fungus for a long time.

Silicate water-based paints

Silicate water-based paint is a mixture of an aqueous solution, liquid glass and colored pigments.

This type of water-based paint has excellent vapor and air permeability and good weather resistance. Silicate paint can last at least 20 years.

But, it is worth noting that if the environment in which the coating is located is more humid than the painted material itself, then it is better not to use this type of water-based paint.

Mineral water-based paints

The composition of mineral water-based paints contains slaked lime or cement. They are used for any surfaces when painting ceilings and walls. However, their main purpose is painting work with concrete or brick surfaces. The disadvantage of these types of water-based paints is considered to be a short service life.

Water-based polyvinyl acetate paint is obtained by rubbing pigments on a polyvinyl acetate emulsion. The advantage of such paints is that they are diluted with water and can be used even indoors, while maintaining good working conditions. Their films are sufficiently high strength, resistant to moisture, fats and mineral oils, and they are also lightfast.

Painting with water-based paint

There are some nuances in painting a room with water-based paint.

Before use, the paint must be thoroughly mixed to a homogeneous mass. If the instructions indicate that the paint can be diluted with water, then it is better to do this, so the paint will lie more evenly on the surface. If there is a desire to give the interior as many bright colors as possible, then this is not a problem at all. To do this, you need to buy a color for water-based paint. This handy thing helps to make color out of ordinary white paint, while selecting the desired shade by mixing.

Initially, it is better to dilute the paint in some kind of small bowl, apply it to cardboard and let it dry. Only then can you determine whether the shade is suitable or not. It is worth noting that the paint has a slightly different shade than the dried coating.

The painting surface must be flat and prepared for painting. Before applying the mixture, the wall or ceiling must be puttied and primed with a primer.

At the expense of choosing a color for the room, there are certain rules. If the windows of the room face south, then cold shades will be ideal: purple, blue, green, blue. If the windows face north, then it is better to choose warm colors: crimson, yellow, red, pink, orange. When choosing shades, there should be no problems, since the colors of water-based paint are very diverse, thanks to which each consumer will be able to satisfy all his wishes regarding the shade of the surface of his room.

Painting walls with water-based paint

Before starting work, you need to free the room as much as possible, plaster all the irregularities, putty and thoroughly rinse the walls if necessary. Do not forget about a respirator, goggles and gloves.

When painting putty walls, it is best to apply three coats of paint, with the first being a primer. When painting walls with wallpaper, two coats will suffice.

You need to paint in stages and in parallel stripes, and you need to move from the window to the opposite end of the room.

For maximum quality of painting surfaces, it is recommended to use special equipment. One of the most popular devices for facilitating the staining process is the spray gun.

The spray gun for water-based paint is a great helper that will help to paint any surface without gaps and sagging. They are very productive and have a large area of simultaneous coverage of the surface.

In order to paint the walls with water-based paint with a brush, you need to take a wide brush with a size of 100-125 mm. And immerse it in paint for a third of the bristles. After that, you need to press the brush against the wall of the container in order to get rid of excess paint. You need to start applying the paint from top to bottom with short horizontal and vertical movements.

Applying water-based paint with a roller is the fastest way to paint the surface, but in this case more layers are needed than with brush paint, since the roller sets up the paint in a thinner layer. The tray needs to be filled about a third with paint, then lower the roller into the paint mixture and roll it over the entire surface several times. This will distribute the paint evenly throughout the roller. After that, you can start painting. The roller along the wall must be carried out in different directions, while evenly pressing on it. Everything must be done carefully and slowly, otherwise the paint may splatter.

Painting the ceiling with water-based paint

The most important thing here is the application of a uniform layer on the surface of the ceiling, for this the entire roller must be covered with the same layer of paint. In order to achieve a uniform distribution of the paint, you need to dip the roller into the paint, then roll it out on the surface of the tray or on a specially prepared material, such as linoleum. This process can be repeated several times if necessary for a perfect distribution. If you skip this process and immediately proceed to painting the ceiling, then due to the uneven layer, after drying, stains may appear on the ceiling, which cannot be removed in the future.

Apply water-based paint for the ceiling in parallel stripes that overlap each other by about 2-3 centimeters. The duration of applying one layer will be about 30 minutes. To achieve a perfectly painted ceiling, you need to apply 2-3 layers of paint and the thinner the layer, the more uniform the surface will be after drying.

In painting the ceiling, the direction of painting the coating is of great importance. The last layer should be located towards the light source. This can hide possible inhomogeneities in the coating structure. After painting the entire ceiling, you can move on to painting those places where the roller did not get it, namely the joints and corners. To do this, you can use a brush and carefully apply a small layer of water-based paint on an unpainted coating.

How to remove water-based paint

The most unstable to moisture is water-based paint for walls and ceilings based on PVA (polyvinyl acetate). To remove this type of paint, all you need is a sponge with soapy water.

In order to wash off acrylic water-based paint, which is resistant to water and soap solutions, you need to use mechanical means - a spatula or an angle grinder disk.

Another effective method of mechanical removal with a spatula is the preliminary pasting of the area to be cleaned with newspapers. To prepare the glue, you need to cook starch in the consistency of sour cream or buy ordinary wallpaper paste. After the glue dries, the paper with paint will be easier to remove.

Also, the paint can be cleaned with a chisel. This is a tedious process, but the paint can be removed very well without making too much noise.

Water-based paint can also be removed with a building hair dryer, annealing area by area with old paint. In this case, you can gradually help with a spatula. This method is suitable for cleaning acrylic water-based paint.

You can also use a chemical based cleaner. After it is applied to the area to be cleaned, it will begin to soak into the paint and gradually destroy it.

The most common way to decorate a ceiling is to whitewash or paint it. And the most used paint for this is water-based. Painting the ceiling with water-based paint at first glance seems to be a simple matter, but there are many subtleties, ignorance of which leads to the appearance of spots or stripes. How to avoid the appearance of such a nuisance, we will tell further.

Preparing for painting

In order for the independent painting of the ceiling with water-based paint to be of high quality and uniform, preliminary preparation of the ceiling is necessary. It is possible to achieve uniform coloring only on a flat, puttied surface. Therefore, before starting work, it is necessary to clean the ceiling from any previous coating (with the exception of a water-based emulsion, which holds very well).

How to remove whitewash

If you have whitewash on the ceiling - chalk or lime - you need to moisten the ceiling with water, and remove the coating with a spatula. Clean everything down to concrete. Even the smallest fragments must be removed. Sometimes it is very inconvenient to scrape small areas with a spatula, it is easier to do it with a wet rag.

In any case, after removing the whitewash, the ceiling should be washed with water and detergent. After complete drying, prime and putty with gypsum or cement (preferably white) putty to an even state, which is also called “under the egg”.

How to remove old water emulsion

If the ceiling has already been painted with a water-based emulsion, simply removing it will not work. The procedure depends on how the paint holds on the ceiling. If it just changed color and you need to update the ceiling, there are no swellings, cracks and other similar problems, you can get by with a little bloodshed. First - remove dust (with a cloth with water), dry, then primed. After the primer dries, you can paint. But once again we pay attention - this procedure is used only if the water emulsion is holding well and there are no defects.

Cleaning waterproof water-based emulsion from the ceiling is still a pleasure

If there are cracks, swellings on the surface of the water-based emulsion, it must be cleaned off. There are two ways - dry and wet. Dry is to clean with sandpaper (manually or using an angle grinder), wet is to wash off. This method has to be used for paint that is not afraid of water. But it is very difficult to clean off such paint. If the water-based paint holds well, no tricks help, but there are surface defects and putty is necessary, take coarse-grained sandpaper and make the surface rough. After that, you can putty. Further - according to technology: primer and then paint.

The ceiling painted with a water-based emulsion is washed off twice abundantly wetting with hot water. The water should be almost boiling water - about 70°C. After wetting part of the ceiling, wait 10 minutes, then again moisten the same area with hot water. After about five minutes, you can remove the paint with a spatula.

Removing old paint is a lengthy process

You can repeat this procedure several times, gradually removing lagging paint from the ceiling. Small residues can be cleaned with sandpaper, and then rinsed the ceiling, dried and primed. On the primer, it is already possible to putty, sand, leveling the imperfections.

Types of water-based paint

Water-based paint is a water-based emulsion that contains polymer particles undissolved in water. The composition also includes pigments and various additives that change the characteristics of the final product. After applying the paint, active evaporation of water occurs and a thin polymer film remains on the surface.

Painting the ceiling with water-based paint begins with the choice of composition. They use four types of polymers:

Acrylic. Aqueous emulsion based on acrylic resins allows you to get a smooth surface, has good hiding power, hides small surface defects, up to cracks up to 1 mm wide. Its disadvantage is the high price, but it is easier to work with it. In its pure form, acrylic compounds are hygroscopic and can only be used for dry rooms, but they do not interfere with the passage of steam. To create a waterproof film, latex is added to the acrylic emulsion. The same additive increases the elasticity of the dried film. Such compositions can be used in wet rooms.
Acrylic-based water emulsion - a smart choice
silicates. This type of water-based paint is based on liquid glass. The coating is resistant to atmospheric precipitation and at the same time does not prevent the removal of vapors, has a long service life (10 years or more), and can be used for outdoor work.
Silicate paints are vapor-tight
Minerals - lime or cement. Mineral water-based emulsions have good adhesion to any surface, but are quickly washed off. As a result, they are gradually losing popularity.
Silicone. Silicone-based aqueous emulsions are the latest in industry. These compositions are good because they "tighten" cracks up to 2 mm thick. As a result, the surface painted by them, even without excellent preparation, is even and smooth. The film is dense, but vapor-permeable. Silicone water emulsion can be used to paint the ceiling in bathrooms and other wet areas. The disadvantage of this type of paint is the high price.

Latex may be added to any of the formulations. Latex water-based paint is water-repellent. It is not afraid of moisture, can be used in wet areas.

Based on the main characteristics of these compositions, you can choose the best type of water-based paint for yourself. Each case requires its own properties and the “best water emulsion” is different each time.

What primer to use

The primer is necessary for better adhesion (adhesion) of the paint to the surface to be painted. It allows you to avoid the appearance of cracks and swelling after the paint dries. If there is no primer, this can happen. Everything will have to be cleaned and re-puttyed. Because in order for the painting of the ceiling with water-based paint to be of high quality, it is necessary to prime the surface well.

The base of the primer must match the base paint. Under acrylic paint, a water-based emulsion requires the same primer, under silicone - based on silicones, etc. Moreover, it is advisable not to save: the quality of this composition depends on how smoothly the water emulsion will lie on the ceiling.

There is an economical way of priming: the main paint is diluted with water (1 to 2) and the surface is painted over with this composition a couple of times. It's certainly better than nothing, but the primer gives a more secure grip.

How to paint the ceiling with a water-based emulsion with your own hands

Each of the water-based paints on the bank has instructions for use. It describes how it works. Some formulations just need to be stirred well before work: undissolved polymers can settle at the bottom of the jar. Some formulations require dilution. The amount of water added is also prescribed in the instructions and depends on the method of application. Under spray guns, they are bred more strongly; when using a roller, thicker compositions are required.

When diluting the water emulsion with water, it must be added in small portions. After mixing thoroughly, test on a surface area. If the paint lays down evenly, almost completely paints over the base, you can paint.

It is more convenient to pour the paint into a special container with a tray and a ribbed platform. You can use an ordinary bowl and a clean piece of oilcloth spread nearby. It's not as convenient, but it's less expensive.

Which roller to choose

A roller for painting the ceiling with a water-based emulsion is needed with a dense short pile. You need to examine it carefully. The pile should “sit” firmly and in no case should it “climb out”, even if you pull on it. Then look at how the seam is made. In no case should it stand out. It must be hard to find. It is best if it is made obliquely.

Devote maximum attention to choosing a roller: the quality of painting - the absence of stripes on the ceiling - largely depends on how good you have chosen the tool. It is more convenient to whitewash the ceiling with a water-based emulsion not from a ladder, but from the floor. To do this, the roller is planted on a long handle and well fixed.

How to paint without streaks

To avoid streaks on the ceiling, painting the ceiling with water-based paint should be completed no later than 20 minutes. Immediately after application, water begins to actively absorb / evaporate, and stripes appear at the junction of the dried and “fresh” color. Therefore, it is desirable to prepare the room. It is necessary to turn off (wrap) the radiators, to prevent the appearance of a draft. It is also advisable to wash the floor immediately before whitewashing, even if you work during the day, turn on the lights, this will allow you to better control the quality of the painting. After that, you can get to work.

Ready-to-use water-based paint is poured into a container, a roller is dipped into it, then it is well rolled over the site, achieving uniform distribution over the entire surface. When the roller has a solid color, they begin to paint.

The corners are painted over with the first brush. After applying a little paint, take a small roller and roll it well. Then they begin to paint the main surface. The first layer is applied parallel to the window, the second - perpendicularly.

It is necessary to stand so as to look at the painted place at an angle. This will give you a good view of how evenly the paint has spread, as well as where you have already painted and where you haven't. Move systematically, without jumping from one piece to another.

The width of the strip to be painted at a time is slightly larger than the width of the roller. After wetting the roller, place it approximately in the middle of the strip. Roll the paint quickly in both directions from one wall to the other. Don't waste too much time, you don't have much. On average, the water emulsion dries up in 10-20 seconds. We didn’t have time to put a strip next to it before - the border will be clearly visible, from which you will not get rid of. Having distributed the paint more or less evenly over the strip, dip the roller into the paint, and again roll it from the middle of the ceiling. At the same time, go into the already painted strip by about 10 cm. All this at a good pace without stops and smoke breaks. The edges of the dyed strip should not dry out. In general, these are all the rules.

After applying the first coat of paint, some places may be less well painted over. It is necessary to wait for complete drying, and paint a second time. This should already be enough to get a flat surface. If even after the third layer of water-based paint you have stripes and stains on the ceiling, you will have to redo it again. It is necessary to level the surface with sandpaper, prime again and paint again.

Which color

The easiest way to achieve perfect evenness of color is when using "snow white" paint. All pigments clearly highlight even small irregularities, so the process should be given maximum attention or use an acrylic or silicone-based water-based emulsion.
