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.
Priming is the initial stage before applying additional coatings to the treated substrate. The primer is characterized by the ability to strongly bind to the substrate and create a uniform coating and increase adhesion. Therefore, the use of earth or primer paint will reduce the cost of the repair. Reduced wall absorption and uniform color means less wear and better appearance top layer.
Which primer to choose?
In addition, the strong adhesion of the paint to the substrate makes it unnecessary to worry about the paint peeling or falling off. Primers and primers are available in stores, and their choice depends mainly on whether we are painting old or new walls. The bases mainly serve to strengthen the substrate and reduce its absorption. Primers are recommended for newly made wall layers, i.e. plaster or plaster, for any dusty and highly damp substrates that are characterized by a high absorption capacity.
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.
The earth strengthens and stabilizes their surface. Primer paints are used to unify the surface and even out the color, in addition, primer paints strengthen the surface and improve adhesion. Primer paints are especially recommended for heavily painted walls because they "cut" the old finish and do not require multiple coats.
Paint your apartment, who can. Painting is not a task that requires special skills. However, it is important to know how to do it and how to avoid mistakes. Malin was looking for an easy way to renovate and style furniture using the white oil paint she used in conservation work. It was based on high quality painted surfaces as well as paint safety.
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.
Produced by Malin 10 colors of paint and 10 colors of wax gives you huge creative possibilities! Seasonally available colors also appear throughout the year. The paints are easy to use and easy to apply. Just paint the surface 1-3 times and after drying, cover it with colored wax paint. Absorbs wax and together forms a durable surface. Interestingly, you don't have to be an expert to get a good result. Uneven painting gives a wonderful effect! Subtle damage to the coating can usually be masked vigorously by rubbing the broken wax with a sponge.
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 water-based paint, you need to pay attention to its technical specifications, which include:
The processed edges of scratches return again, and the scratch disappears without a trace. Of course, it is impossible to recover serious losses in this way. The effects that can be obtained depend, in particular. on the method of painting, as well as on the thickness of the applied layer. For coloring, "smooth" paint can be thinned with water. Resurrection is recommended the next day after painting. Leaving too thick a layer of wax can result in more matte areas. After waxing, the surface can be polished with a cloth.
If desired, the grinding surface can be sanded with sandpaper. For drawing the picture is not used paint, but wax. It is much thicker than paint, so it does not dissolve and there is no blood flow during operation. Use a sponge when working with templates, determining the place. The applied sample takes several hours to complete cure and fixes. Free-drying the wax has its advantages: if the effect doesn't show up as it should, you can wipe the pattern down to a base layer of wax and reapply it.

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 result of their research is a paint based on purified protein linseed oil- Extremely durable and efficient. General purpose paints are available in 32 colors that can be freely mixed for virtually unlimited creative possibilities.
Were you bored by the current type of furniture?
Contains a blend of natural cellulose for a pleasant touch. Waxes are available in 9 colors. Cement furniture paint is a great solution when it comes to metamorphosing old objects that can get a unique look again. Plus, you can look forward to some fun because self-renewing, repainting, and decorating can be a form of outdoor activity.
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%.
Change your interior to not know i.e. chalk paint for furniture. Fine furniture paint was created from natural ingredients and water, and now the basic formula has been improved technologically. Thanks to this, you can count on a satin or matte effect, a slight sheen or metallic color. Cement paint for furniture is also available in a moisture resistant version that works great in the kitchen and bathroom. They are effective, easily grip the surface, hide well and dry very quickly.
You don't have to spend a lot of money to buy new furniture to enjoy your new interior design. Just put some chalk paint on furniture for unique effects. Satisfaction and guaranteed savings. The big advantage of chalking is that you don't have to remove old layers or prepare the surface of the furniture. Just clean and degrease the furniture and then move on to the main task, which is painting. The good news is that even inexperienced people in this profession can easily cope, because even without precision they can count on amazing results.
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.
Hiding old radiators behind heavy curtains or furniture is not a good idea. Thus, we limit the heat inside. So if our cast iron radiators don't look right - it's time to renew them. Summer season - best time to upgrade radiators.
What color is the radiator paint? . We can use metallic paint, but pay attention to whether they meet very important parameters. The first should have increased resistance to high temperatures. Secondly, they do not turn yellow under the heat. Another important feature is high viscosity and excellent adhesion to substrates.
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.
You can find out what options are available on the package. Now paint manufacturers offer products designed for painting radiators. These are mainly water-soluble paints, acrylic binders, as well as quick-drying acrylic paints with excellent coating properties.
How to prepare paint heaters? . Before we start drawing the heatsinks, we need to carefully prepare the substrate. It must be dry, dusty and free of grease. Cover the rusty ribs with a wire brush and clean the old paint off the paint - we'll remove it. We must grind everything else with sandpaper and carefully pour.
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.
Does the painting of radiators require a primer? . Exposed metal parts of the radiator must be primed. Corrosion primers are best suited for this purpose. Unfortunately, we usually think about heaters when we heat up. Painting hot radiators is not a good idea. The maximum substrate temperature used for radiator paints is 30 degrees Celsius. The higher the drying speed, the unevenness and coating is unstable.
Cast iron heaters, preferably painted at room temperature, leave about 4 hours to dry between one coat and another. So if we decide to paint the radiators now, let's wake them up, wait for them to cool down and apply the paint.
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.
Paints, varnishes, enamels for painting radiators
We can turn on the heaters after the coating has cured after about 24 hours. The exception is quick dry paints- painted radiators can be turned on without waiting for the coating to dry. Painting an apartment does not require high financial or special power, which is why many people prefer to paint themselves. A large selection of paints at similar prices does not make it easy for us to choose the right one. However, when we suffer from allergies or are concerned about our own safety, we must follow the composition of the product.
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.
What to look for Special attention? Among ordinary paints, we must choose acrylic paints on water based and latex paints. They contain less harmful substances and they dry out faster. The drying process refers to the process of complete emission of chemicals. Touching the walls, we can tell that it is dry, but in fact it is still dried, releasing chemicals and exposing us to inhalation.
The main components of paints are the so-called. volatile organic compounds. On the contrary, these compounds are harmful to health. Paints can contain hundreds of different volatile organic compounds, but one of them can have a particularly negative effect - propylene glycol. His research is helping scientists understand the sudden rise in asthma and allergies in a rapidly advancing civilization. Children who were infants or early children were buried in rooms freshly painted or repainted up to a year old.
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 works with concrete or brick surfaces. The disadvantage of these types of water-based paints is considered to be a short service life.
High concentrations of this volatile substance can cause twice as many respiratory, skin and asthmatic allergies in the youngest. It should be noted that dangerous concentrations of propylene glycol have been found in paint rooms painted with water-based paints. The more you know about oil paints, which emit much more volatile substances.
It is recommended to use a risk-free paint, as well as a reasonable frequency of repainting. It is important that harmful substances can remain inside for up to a year, even if we no longer feel them. The release of harmful chemicals is affected by heat. When exposed to heat, the paint releases volatile chemicals, causing breathing problems, nausea, and pinched eyes.
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 you can work with them even indoors, while maintaining good conditions labor. Their films are sufficiently high strength, resistant to moisture, fats and mineral oils, and they are also lightfast.
Choosing the right paint that is not labeled as an allergic paint can be a challenge. The law does not require the exact content and concentration of chemicals on the label. For getting detailed information the only solution is to contact the manufacturer directly for a request. Material Safety Data Sheet, which contains the detailed specification of the product.
Allergists who are looking for natural ways to paint walls can opt for clay paint. They are made on the basis of natural clay, dust and sand. They are available in earthy colors, but also with safe color additions in subtle shades. They have a long-lasting effect and do not contain harmful volatile substances, preservatives or adhesives. They take a little longer to dry, but are a relief for asthmatics and children. They are also ideal for those who appreciate an eco-friendly lifestyle.
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 large area 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 most fast way surface, but in this case more layers are needed than with a brush, since the roller adjusts 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 uniform distribution 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 way mechanical removal with a spatula is considered to be a 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.

It is difficult to find a person who has not heard anything about water-based paint. water-based paint allows you to make the apartment beautiful and cozy.
Water-based paint is used to paint the walls of the bathroom.
For wall decoration, a huge number of different types of building materials are offered. With their help, you can create any design. Painting walls with water-based paint does not lose its relevance due to its availability, simplicity and environmental friendliness.
Features of choice
Water-based paint is an aqueous mixture of the smallest polymer particles and various additives. All these components are in suspension. The basis is made up of polymeric substances that form a film when dried. To give white color contains zinc oxide or titanium dioxide. In addition, various fillers, plasticizers, antiseptics, etc. are added. An adhesive composition (usually CMC glue) is used as a thickener.
The solvent for the paint is water. The following composition is most common: polymeric substance - 50%; pigment and filler - 37%; plasticizer - 7%, other elements - 6%.
Depending on the type of polymer used, modern water-based paints are divided into the following types: acrylic, silicone, silicate and mineral. Acrylic water-based paints, which are based on acrylic resins, are most widely used. Latex is added to high-quality dyes. Coatings with such paint have sufficient water resistance, have a density, and have good adhesion to many materials.
Silicone paint refers to coatings that form a vapor-permeable layer. This allows you to apply the material on the walls of rooms where there is often high humidity. It is resistant to the formation of fungi and mold. By its density, the paint is able to mask cracks up to 2 mm. The disadvantages include the increased cost.
Silicate water-based paints are based on liquid glass with colored pigments. They have increased resistance to atmospheric factors, very high permeability to steam and air. Its service life is quite high. In terms of moisture resistance, this type is somewhat inferior to silicone paint. Mineral water-based paints may contain slaked lime or cement. Therefore, such paint easily falls on concrete walls. Polyvinyl acetate paint of this type has high strength after film formation, withstands water, fats and oils quite well. An important positive property is high light fastness.
Water-based paint has a number of parameters that should be considered when purchasing it for painting walls. The main characteristics should include:
- paint base;
- consumption during coloring;
- viscosity during implementation;
- specific gravity;
- storage period;
- best before date.
High-quality paint has a consumption (when painting in one layer) of 150-200 ml / m². The specific gravity should be approximately 1.35 kg/l. Drying time should not exceed 24 hours. At the same time, high-quality paints dry in 2 hours.

Paint preparation
Water-based paint is sold in polymer or metal containers of various sizes. The factory container contains instructions or recommendations for use. Including the expense is usually indicated, which allows you to estimate the amount of paint required for the purchase.
In addition, water-based paint is sold in various consistencies. It may be ready for use (indicated in the instructions) or requires stirring in water to a suitable consistency. If the paint is too thick, then it must be diluted with water and mixed evenly. Usually, before painting walls with water-based paint, construction material mix by hand to the consistency of milk. However, the best option is mixing with a mixer or an electric drill with a mixer hen. If a voluminous texture is provided on the wall, then the material is not diluted, but applied in a very thick form. Immediately before applying to the walls, the emulsion must be re-mixed thoroughly.
Painting bathroom walls helps protect them from moisture.
In the case when the painted walls must have a certain color, you should take care of the color in advance. Currently, water-based paints of different colors are on sale, but if you pick up desired color failed, then you should take white paint and add the desired color scheme or a combination of several colors to it. When selecting the desired color, you should first check in a container of no more than 100 ml. Color is gradually added to the paint with thorough mixing. Control smears are made periodically. When the desired color is reached, the desired color concentration is fixed. Only after such a check is a larger amount of paint colored. It should be borne in mind that the color of the paint changes when it dries, so the control smears must be given time to dry.

Preparing for painting
Modern water-based paints are able to lay down on almost any surface, including concrete. However, all wall irregularities will show through the coating. This requires preliminary preparation of the wall surface before painting. The surface of the wall must be smooth and level.
To do this, a thin layer of finishing putty is applied to the entire surface. After the putty has dried, the wall is grouted and sanded with a sanding mesh or fine emery cloth. Immediately before painting the walls with water-based paint, they must be cleaned of dust.
The wall itself must be freed from any objects (including nails, screws, etc.). The space in front of the wall should be free of furniture. It is recommended to cover the floor area, the plinth with a film from splashes.

Tools
You can paint walls or ceilings with water-based paint using:
- paint brush;
- paint roller;
- spray gun.
A sponge is used to apply volumetric texture. The most uniform and fastest painting is carried out with an airbrush, but not everyone has it. In addition, certain skills of the painter are required to use it. In order to paint the walls with water-based paint with a paint brush, it will take a very long time. Therefore, the paint brush is used when touching up in hard-to-reach places, as well as in the corners of the wall. In order to paint walls with water-based paint, you need to have paint brushes of different widths (from 2 to 10 cm).
The most common painting with a paint roller. It is best to use a soft bristled roller. middle length(about 16-20 cm).
