Water-based paints and varnishes. Types and features of water-based paints Technical characteristics of water-based paints
At all times, paint has been used as a versatile interior decoration product. However, when working with oil formulations, the coating dries for a long time, and the mixture itself emits an unpleasant odor. The same cannot be said about water-based solutions. In this article, we will describe what a water-based paint is (technical characteristics, advantages and method of manufacturing the composition).
Method for the production of water-based paint
The whole process can be roughly divided into several stages. The first is the combination of a solution of an aqueous polymer dispersion with a pigment and a filler. Second, the resulting mixture undergoes dispersion (grinding of solid and liquid bodies). The third is the addition of additives that are necessary in accordance with the TU. The fourth is packing the finished material into cans.
Dispersion of ingredients is carried out in special dispersers (mills). These devices have several chambers, and in them there is a shaft with disks. It is with the help of it that grinding occurs. The resulting mixture is placed in a dissolver (mixer) container. Thorough mixing takes place there, components are added according to TU.
The mixing time of all ingredients depends on the properties of each component, the total volume of the mixture, as well as the technical capacity of the dissolver and dispersant. Typically, 30 minutes are enough for each operation. In this case, all work must be carried out at a temperature of +5 ° C.
At the last stage, containers and strainers are prepared. It is through them that the finished paint will be poured.
Advantages and disadvantages of water-based paint
Water-based paint for walls and ceilings has a number of advantages over oil-based paints. First, she dries faster... Sometimes, just a couple of hours is enough for the coating to dry. Secondly, absolutely safe and harmless to humans and the environment. This means that during painting work, there is no need to urgently leave the premises.
Thirdly, the paint does not have a strong odor, which usually lasts for several weeks after the completion of the work... Fourth, the coloring composition can be given almost any shade, while adding special pigments... For this, a special colorless composition is even sold. In hardware stores, as a rule, a catalog of colors and pigments suitable for them is offered.
Fifth, the process of applying paint is quite simple, and all tools can be easily cleaned with plain water... You don't need to use any solvents. Of the shortcomings, only a few can be distinguished: work can be performed only at a temperature of +5 ° C, the material is not cheap. For outdoor use, you need to choose the most expensive paint, since outdoor conditions are significantly different from indoor conditions.
Water-based paint: technical characteristics
Water-based paint for ceilings and walls has the appropriate technical characteristics. These include: composition, consumption, specific gravity, viscosity, storage conditions and shelf life. Composition of water-based paint: latex, thickener, fillers, antiseptic. Consumption for one layer about 150-200 ml / m 2. The number of layers depends on the absorbency of the substrate.
Viscosity water-based paint is determined by a viscometer and should be equal to an average of 40-45 s (when applied with a brush), 20-25 (when using a spray gun). Basically, viscosity is a measure of how diluted a paint is with water. That is, water is added to the composition to a certain level, and then a measurement is made with a viscometer.
Specific gravity water-based paint is about 1.35 kg / l. Adhesion on average it is 2.0MPa. Drying time is 2 to 24 hours. It all depends on the temperature and humidity of the air. The desired temperature is about + 20 ° C, and the humidity is 65%. Store the paint in a dark place (away from sunlight).
Water-based paint: technical characteristics and method of production
Water-based paint, technical characteristics - how do they affect the work process? What material parameters are important to know? About this in the video tutorial.
High-quality coloring is not only the result of the correct use of the coloring composition, but also a combination of certain characteristics of the material that determine decisions in this direction. In paintwork, the selection of such an indicator as paint viscosity in DIN becomes the key to success. The table of optimal values presented in this article will help in this matter.
What depends on the viscosity?
The very concept of viscosity hardly requires additional clarification. But, here are some other characteristics that the conditional viscosity itself can affect:
- If the colorant is too viscous, it is difficult to distribute it evenly over the entire surface. Excessive layer thickness will result in too long drying time. The final strength of the coating, on the other hand, decreases.
A solution that is thick in consistency will not fill irregularities on the surface. This means that the adhesion is deteriorating.
- A large layer thickness is the reason for the formation of smudges and other similar defects.
- Finally, an inexpensive spray gun simply cannot handle materials that are too viscous. The main principle of operation for pneumatic spray guns is low pressure in the air stream, paint suction from the tank. They help those who are interested in how to determine the viscosity of a paint.
If the pressure drop is not enough, then the fixtures will have to be disassembled and then thoroughly rinsed. The paint diluted with additional efforts is also harmful. The number of layers required for high-quality processing increases. The time spent on this or that work grows, including in which the spray gun is involved.
Measurement features
What units?
It is typical for domestic manufacturers to indicate this parameter in seconds. But imported materials imply the use of a different designation - DIN. What is the meaning of these combinations? And how is the characteristic measured?
They are only needed to indicate the time (in seconds) after which the composition passes through holes of a certain diameter, previously known. If the paint is thinner, then it leaves the container faster. In the case of a thick composition, this takes longer. This does not affect how to use the viscometer.
About techniques and tools
A viscometer is a special instrument used when measuring a liquid, a small funnel, strictly having a capacity of 100 milliliters. There is also a hole up to 4 millimeters in diameter. Devices with sufficient accuracy for effective use in everyday life cost from 200 to 500 rubles. They are used for routine viscosity measurement. Devices used in laboratories are much more expensive. Sometimes the cost reaches hundreds of thousands of rubles.
Instructions for using this device are as simple as possible:
- First, fill the funnel by plugging the inlet with your finger.
- The stopwatch starts as soon as the hole is opened.
- All that remains is to record the time elapsed until the tank is completely empty. Individual drops are not taken into account for paint viscosity in DIN, the table confirms this.
The temperature of both the paint itself and the surrounding air should not exceed 18-22 degrees. Any formulation will thicken at lower temperatures. And at higher rates, on the contrary, it decreases. Because of this, the paint viscosity experiment will not be as successful.
What are the optimal values?
The manufacturer usually writes on the packaging about which indicator is considered optimal in certain conditions. But information is easy to find on the official website, including for viscous liquids.
Determination of paint viscosity in DIN and table of recommended values
The viscosity of the paintwork material in DIN, shown in the table, is a key parameter when carrying out repairs. What are the optimal values?
Water-based paints are currently a very popular, high-quality, affordable and promising repair material. They are easily applied to cleaned surfaces (concrete, gypsum concrete, wood and pre-plastered), are environmentally friendly and very practical. And in combination with the color scheme, you can always choose the color scheme necessary for the interior.
Advantages of water-based paint
Water-based paint is in demand due to the following characteristics:
- not flaking during a long period of operation,
- lack of cracks and unpleasant odor,
- ease of application,
- fast drying process,
- acceptable cost.
Besides, water-based paint vd allows you to get almost any shade by adding special pigments. Often, home improvement stores provide a catalog of colors and matching pigments.
The main disadvantages of water-based paints
These paints have practically no drawbacks. At the same time, it should be noted that it is extremely undesirable to apply them on metal and glossy surfaces, due to the presence of a large volume of water in the paint composition.
Today, on the market more and more obvious fakes of "water-based emulsions" began to appear, which disappoint consumers. They fit very poorly on the surface to be painted, differ in overspending, get dirty during the drying process and are washed off in case of water ingress.
Technical characteristics of water-based paint
Water-based paint has the following composition: latex, thickener, various fillers and antiseptic. The average consumption rate of water-based paint is 250 grams per square meter. The number of layers applied will directly depend on the absorbency of the surface to be painted. The viscosity of the paint is determined using a special device - a viscometer. This indicator should be within 45 s. (when using a brush), and 25 sec. (using a paint sprayer). By definition, viscosity is a measure of the degree of dilution of a paint with water. The specific gravity of the paint is approximately 1.35 kg / l. Adhesion is 2.0 mPa, final drying time is 2 to 20 hours (depending on temperature conditions). Store the paint in a dark and cool place (away from sunlight).
The main types of paints
Depending on the polymer present in the paint composition, there are four main types of water-based emulsion ( water-dispersion, latex or emulsion) paints:
Even among such a small variety, a potential consumer involuntarily arises a question: "So which water-based paint is better?" Let's take a closer look at the characteristics of each of them.
Acrylic water-based paints - quality comes first
This type of paint is most popular both among professional craftsmen and among ordinary consumers who are trying to master the repair on their own.
Based on the name, it becomes clear that acrylic resins are included in the paint as the main component. Such paints are applied to surfaces of brick, wood, glass, concrete and plaster. The most common representative is veak 1180 water-based paint.
The main disadvantage of such paints is their expensive cost. Therefore, analog paints with acrylic copolymers have become widespread. Their price is much cheaper than real acrylic, and the quality is not much inferior to the original. Sometimes, to increase the elasticity of the acrylic coating, latex is added to the paint, thereby effectively resisting moisture.
Painted coatings can be safely washed with water without fear of ruining the applied paint. Manufacturers in the technical characteristics of water-based paint indicate that it is able to withstand up to 5,000 washing cycles with water. By applying a double layer of acrylic latex paint, cracks on the surface (up to 1 mm thick) can be masked. And they dry out at room temperature in just a few hours.
Silicone water-based paints - ideal for rooms with high humidity
In silicone paints, silicone resins predominate in the composition. They are a universal coloring and concealer for all surfaces, hiding two-millimeter slits from prying eyes. Silicone paint is also very expensive, but it has a vapor-proof property, ideal for damp areas of the house, which are characterized by moisture formation. Thus, the paint will also actively fight the emerging fungus, preventing its reappearance.
Silicate water-based paint - an indicator of durability
Silicate water-based paint is a mixture of liquid glass, water with the possible addition of colored pigments. It is characterized by weather resistance and a long service life (up to 20 years). But for excessively damp surfaces, it is better to use a different type of paint.
Mineral water-based paints
In the process of manufacturing mineral water-based paints, slaked lime or cement is added to their composition. They are used for all surfaces in the process of painting walls and ceilings. Their main purpose is painting with bricks and concrete surfaces, which are subject to significant hydraulic loads. A distinctive feature of mineral paints is a short service life, so they gradually cease to be in demand.

Characteristics of VD paint.
Before purchasing such a paint, you should pay attention to its characteristics: specific gravity, viscosity, composition, shelf life, storage conditions and drying time. Latex, filler, antiseptic and thickener can be found in the composition of water-based paint.
Viscosity is a measure of the degree of dilution of a colorant with water. The viscosity of such a paint is from 40 to 45 s, in the case of using a brush when applied, and from 20 to 25 s. When used with a spray gun.
Depending on the manufacturer, the composition of the water-based paint may differ. The smallest particles of polymers that are in the composition of this substance are suspended in an aqueous medium. Manufacturers add various substances to these particles, which determine the brand of the coloring composition.
Depending on the state of the components added to the composition of the paint, its purpose may vary. To obtain a white saturated color, a white pigment is added to the dye. In the case of inexpensive formulations, chalk is used to obtain this color. For these purposes, different manufacturers can also use other fillers: mica, calcite, talc, and so on.
Composition of VD paint.
The composition of the water-based paint, as well as in, includes a thickener, which is necessary to create the desired consistency. Depending on the brand of the coloring matter, the proportions of some of the components that make up its composition change.
But ideally, the overall picture will look like this:
- Plasticizers - from 5 to 10 percent;
- Film former - from 40 to 60 percent;
- Fillers and pigments - from 30 to 40 percent;
- Other additives - from 5 to 10 percent.
- This coloring agent is distinguished by good permeability to moisture and steam; therefore, it can be used for both external and internal work, for application on a plastered and unplastered surface;
- The composition of the water-based paint does not allow it to flake off. It is an environmentally friendly and non-hazardous type of paint;
- Very often latex can be seen in the composition of this type of substance, which gives the painted surface a strong water-repellent effect. And at the same time, the fact that this effect does not interfere with vapor permeability is of great importance;
- Water-based compositions have a wide range of colors. You can easily use a custom color to get the color you want.
People have long been using water-based paint for walls when decorating interiors and for outdoor use. Water emulsion began to rapidly gain popularity. This paint consists of water, small polymer particles, fillers, additives and pigments.
Coating features
Water-based acrylic paint can be called universal: it can be used to decorate any surface. It is applied to the following materials:
- brick;
- tree;
- drywall;
- concrete;
- wallpaper for painting.
Each type of paint has its own advantages and disadvantages.
Types of material
Water-based solutions are divided into several categories.
Acrylic composition
The most popular type of coating, which is used very often. This water-based paint for walls and ceilings is resistant to various influences due to the presence of acrylic resins in the composition. When dirty, the surface is easy to clean, so this composition will be ideal for offices and residential premises.
Coating features:
Silicone resin based material suitable for application to any mineral coating. TO
the main advantage is the elasticity of the composition. Cracks up to 2 mm are painted over. The silicone composition is distinguished by its vapor permeability.
Such paints can be used in a room with high humidity: in the kitchen, bathroom, shower, basement. Due to the filling of irregularities and roughness, the material is resistant to mechanical and temperature influences, moisture. It can even be applied to plaster without first priming the walls.
Silicate look
This water-based interior paint consists of an aqueous solution, colored pigments and water glass. There is no film on the surface; instead, there are strong chemical-physical bonds. They are resistant to weather and mechanical stress.
Manufacturers guarantee a long service life - up to 20 years. Suitable for finishing open terraces.
Attractive value for money. It is made on the basis of PVA, it is chosen for interior decoration.
There are many advantages:
- fits well on plaster, cardboard, wood and other porous materials;
- can be used in a room that needs an increased level of fire safety;
- does not contain harmful components;
- fast drying.
She does not have a very rich color palette, but this can be easily compensated for with the help of special colors that will give the composition any shade. The use of additives will help to obtain a glossy or matte finish..
Mineral and latex based
Mineral coloring composition contains hydrated lime and cement, suitable for
painting brick and concrete surfaces. The service life is not very long, therefore, it has not been in particular demand lately.
If you need to create a surface that is not exposed to moisture, then you should choose washing options that contain latex. The coating will withstand a large number of wet cleaning, suitable for painting walls and ceilings in the kitchen and bathroom. The prices are average.
Latex compounds are good at repelling moisture and bridging large cracks well; before applying them, a particularly thorough surface preparation is not required.
Gloss degree
Water-based paint is also divided according to another indicator - according to the degree of gloss... Manufacturers offer:
- glossy;
- matte;
- deep matte;
- semi-matte (silky matte);
- semi-gloss;
- highly glossy.
Semi-gloss and glossy compositions are abrasion resistant when compared to matte options. They can be washed much more often, because the surface of such a material is even and absolutely smooth. Cleaning with a damp cloth does not change the texture, but the matte surface can be wiped off, and this will result in shiny, unsightly stains that need to be painted over.
Before buying a material, you need to study its main characteristics - consumption, composition, drying time, storage conditions, specific gravity, shelf life. Each point needs to be given special attention..
- Viscosity. This figure should be quite high. It is he who determines the degree of dilution of the composition with water (when applied with a brush, it fluctuates between + 40 ... + 45 ° С, and when using a spray gun + 20 ... + 25 ° С.
- Consumption. Typically, 1 m² contains 150 g of product, 250 g if the coating is two-layer. Manufacturers can unintentionally mislead buyers by indicating on their product that it has a consumption of 110-140 g. But these indicators usually correspond to ideal conditions: the walls must be plastered and completely smooth. But it directly depends on the surface roughness, material, painting method and absorbency. For example, it is more economical to apply with a roller than with a brush.
- Expiration date - 2 years from the date of manufacture. It is worth observing the storage conditions: the place must be cool and dark, the composition must not be frozen.
- Drying. Depends on air temperature and humidity. The optimum temperature is + 20 °, air humidity is 65%. Drying time ranges from 2 to 24 hours.
Quality and manufacturers
The high price is a clear sign of the quality of the water-based formulation.... It should be understood that 90% of materials and components for the material are imported from Europe, so the price for 1 liter cannot be lower than 70 rubles. A significant decrease in cost may indicate poor product quality.
The weight of the paint is also an indicator of quality. Its average density ranges from 1.35-1.5 kg per 1 liter, therefore, a 10 liter bucket cannot weigh less than 15 kg. It is better not to buy the composition in the winter on the open construction market: when it freezes, the paint loses its properties.
You need to choose a trusted manufacturer. Dulux can be called the leader, but Tikkurila also has good technical characteristics along with the highest quality. The compositions of the German Dufa also proved to be the best. And Johnstone's from the UK has a high price due to the excellent quality. From domestic products, Eurolux and Admiral are more often chosen. The price for such compositions is quite affordable, and the quality is up to the mark.
Surface painting technology
Usually, there are no significant problems with painting walls, and finishing the ceiling can be attributed to a more complex process in technical terms. Before work, it is required to prepare the surface: remove all the old coating, grind, level. Then the consumption of the coloring composition will be significantly reduced..
The water-based composition itself is often used as a primer, which is diluted 40% with water, although experts advise using a primer for a specific type of surface.
The colored material must first be tested to determine what the color will actually be. To do this, just apply it in a thin layer on the wall and wait until it dries. Usually the color comes out 1-2 tones lighter than in a bucket. The difference is usually not significant.
The painting of the ceiling and walls starts from the far corner of the room from the window, then the remaining corners and joints are painted over. A 5 cm wide strip is applied along the perimeter of the ceiling, then you need to go to the spray gun or roller. To obtain an even color, you need to apply 2-3 thin coats - this is better than applying 1 thick coat.
Layers of paint are applied perpendicular to each other. The next layer is applied after the previous one has completely dried. The last layer is applied parallel to the light rays: due to this trick, small irregularities and errors are almost invisible. You can use textured glass wallpaper to eliminate possible problems. The woven textured surface will mask dyeing errors.
There is nothing difficult in painting walls and ceilings with water-based paint. The work does not take much time, and a beginner master can cope with it, if you approach the matter with full responsibility. With the help of a water-based coating, you can update your home interior in a short time.
Today, water-based paint for walls and ceilings is widely popular for renovation work. It has many advantages, is functional and at the same time is very affordable. If you decide to use this material, it will be very useful to learn about the features and technical characteristics of water-based paint.
Water-based paint is a water-based material that forms a film with an emulsion of polymer components - polyvinyl acetate, polyacrylate, styrene-butadiene, etc. It has excellent performance properties, fire safety, environmental friendliness.
When choosing an aqueous emulsion composition, the following factors, characteristics and features should be taken into account:
- Paint components. The composition of the aqueous solution may include various fillers, thickeners, antiseptic agents. It is the composition of the paint that affects its purpose and scope - it can be rooms with high humidity, external or internal surfaces.
- Scope of use. Different formulations can be designed for painting different types of surfaces, such as wood or concrete, or they can be universal. These characteristics of the water-based paint are influenced by the composition.
- Consumption of paint and varnish composition. Calculate the amount of paint in milliliters, based on how much it will be required to cover 1 sq. m in one layer. The average is 180 ml per square meter. It is important to take into account factors such as the condition of the surface and its appearance.
- Specific gravity. A high-quality water-based paint has a density of approximately 1.5 kg per 1 liter of composition.
- Viscosity. This characteristic of an aqueous emulsion composition indicates the degree of dilution with a liquid. For use with a roller or brush, the viscosity should be 40–45 Art. If the composition is applied by means of a spray gun, then no more than 25 Art.
- Humidity of the environment. It should be taken into account during the application and subsequent operation of the coating.
- Drying time water emulsion composition. It ranges from 2 hours to a day. The difference depends on indoor humidity and ventilation, which affect the evaporation of water. The recommended operating temperature is 20 degrees Celsius, and the air humidity is 70%.
- Storage conditions. Best before date. The service life of the coating. The shelf life of water-based paints is limited to 24 months from the date of production. Afterwards, the paint should be stored in a cool, dark place and should not freeze.
Good to know!
Water-based paint always has a white color, and various shades are given to it by adding special pigments and dyes.
Water-based paints are water-based materials with polymer components. The composition contains emulsions of polymers such as styrene-butadiene, polyvinyl acetate, polyacrylate. They are appreciated for technical properties, safety, ease of use.
Description and features of water-based paint
(a type of water-dispersion) is used mainly for interior decoration. These are emulsions made from polymer particles, pigments and liquids.
The performance characteristics of such compounds allow them to be used in public areas with high traffic, when the wear of the finish occurs quickly. Can be used for swimming pools, gyms, residential buildings.
The components in such materials are:
- film formers;
- fillers;
- dyes;
- various additives to improve performance - defoamers, stabilizers, plasticizers.
Dispersions can be obtained from any polymers, but polyvinyl acetate, acrylic and styrene-butadiene copolymers are often used for the manufacture of paints.
Pros and cons
There are such Benefits:
- the solution can be given the desired shade by adding the desired pigment;
- can be applied in several layers;
- clear instructions for use;
- paint without a specific smell, it is comfortable to work with it;
- the application process does not cause difficulties, the tools are easily cleaned of paint;
- drying takes place in 1.5-3 hours, depending on environmental conditions;
- low consumption of the coloring emulsion.
The downside is the temperature at which you can paint. It is permissible to work with paint under the condition of + 5 ° С. Low frost resistance limits its use in the cold season. Some representatives of water-based formulations require a long drying time - up to 24 hours, which the manufacturer indicates in the instructions.
Specifications
Water-based formulations differ in the following features and properties:
- consumption - 150-200 ml / m² are consumed for 1 layer, the second layer is required depending on the absorbent properties and density of the material to be painted;
- viscosity - determines the degree of dilution of the composition, should be 40-45 s, when using a special sprayer - 20-25;
- specific gravity - 1.3 kg / l;
- drying time - up to a day, depending on the humidity in the room and temperature, most brands have a high drying rate;
- shelf life - 12 months in a tightly closed container at a temperature of + 5 ° С;
- fire hazard class - KM0-KM1.
Optimal conditions for drying are 65% humidity, + 20 ° C temperature.
Types of water-based paints and their scope
Types of paints and varnishes are distinguished by the polymers included in the composition.
Types of water-based paint. Water-based materials are of the following types:
- polyvinyl acetate;
- mineral;
- silicate;
- acrylic;
- latex;
- silicone.
According to the area of use, they are divided into soil, facade and interior decoration.
Primers are used to increase the adhesion of the substrate to be painted, to strengthen the substrate, and to eliminate minor defects.
Facade must be resistant to adverse external factors and abrasion, not afraid of UV and microorganisms. There are special requirements for compositions for internal work, but their water resistance may be low.
Polyvinyl acetate
They were the first to be used for the manufacture of paints. At room temperature, this polymer is solid, and plasticizers provide flexibility to it. The composition additionally contains stabilizers and pigments. It is sold as a ready-to-use one-component composition that does not need to be prepared by mixing before starting work.
Water-based emulsion is used more often for staining indoors. It contains no solvents. It dissolves well in water, forms an elastic coating, has good adhesion and does not have an unpleasant odor.
Polyvinyl acetate water-based paint. Properties of polyvinyl acetate compounds:
- increased resistance to wear factors;
- not harmful;
- fire safety;
- durability of the shade;
- you can hide defects up to 1 mm;
- long operational period;
- prevention of the formation of fungus and mold.
Mineral
Mineral formulations contain cement or lime. Their advantage is the ability to use on any surface. They are well suited for walls and ceilings in an apartment. Can be used outdoors. The disadvantage of such a composition is a short period of service.
The advantages are also high strength, moisture resistance, resistance to mineral oils, fats. Such paint is not afraid of the sun color, over time it does not peel off.
Silicate
A silicate water emulsion is made from liquid glass with the addition of pigments. Differs in excellent air and vapor tight properties and long service life - up to 20 years. Well suited for buildings with unstable groundwater.
The consumption of the composition is small - up to 300 ml / m². The density depends on the method of application, for a paint brush it is lower than for a spray. It is used for facades and interior decoration. The downside is how much such paint dries. This takes about a day.
Acrylic
Acrylic water-based paint. Acrylic is the most common compound. The base contains acrylic resins. Additionally, latex can be used. They can be glossy, matte for painting walls and ceilings.
Key benefits:
- quick drying, with the exception of the most budgetary types;
- resistance to ultraviolet light, mechanical factors of influence;
- moisture resistance;
- non-toxicity.
The product has good adhesion to a wide variety of substrates. Can be applied over old paint if it cannot be removed without compromising performance.
Acrylic emulsion is an alternative to waterless enamels. It is affordable, dries quickly, and has a wide range of applications.
Latex
Latex water-based paints and varnishes have become widespread due to maintaining the microclimate in the room. They comply with GOST standards, have a good price, and are safe for use inside the building.
Latex composition can be used to paint concrete, brick surfaces, wallpaper, plaster. Suitable for ceiling decoration. The paint creates a moisture resistant coating that can be washed with water. Included in the class of safe non-combustible materials.
The disadvantages will be poor resistance to ultraviolet light, lack of protection against fungus, intolerance to subzero temperatures. Peels off under unfavorable conditions.
Silicone
Application of water-based silicone paint. Water-based silicone paint is a mixture of persistent silicate and acrylic emulsions. Has improved characteristics due to the content of emulsified resin.
It is used for cement substrates, bricks, plastered surfaces, stone, drywall. Distinguish between interior and front types.
Silicone emulsions are water resistant, do not allow steam to pass through, and prevent the formation of mold and mildew.
During the period of operation, they do not need to be treated with antiseptics. The disadvantage is the relatively high cost.
Which is better
For finishing the ceiling and walls, craftsmen often prefer acrylic emulsion. This is due to its durability, strength, quick drying, resistance to ultraviolet rays. Another advantage is that you can wash the surface with water, which is necessary for the kitchen and bathroom.
Acrylic emulsion fits well on popular surfaces - glass, brick, wood, concrete, metal, plaster. The paint is not washed off over time, the components of the water-based paint are highly resistant to the effects of liquid. A double coat of paint can mask minor imperfections.
Water-based emulsions can be selected for indoor and outdoor use in an environmentally friendly manner. Water-based paints and varnishes can be used in conditions of high humidity. At the same time, they do not tolerate the cold.
The most popular water-based materials are the compositions of German manufacturers. Produced by Caparol, Dulux, Dufa. In Russia, a popular foreign brand is Tikkurila.
When choosing a paint, you need to focus on the type of work carried out, the environmental conditions. The instructions for each composition indicate the scope and application rules.
