If we discard all scientific terms and designations, then polyvinyl acetate water-based paint is an ordinary emulsion made of the “oil in water” type. The main components of this paint and varnish material:
In principle, the action of such paints lies in their main advantage. After the paint is applied to the surface, the water included in the emulsion begins to evaporate. As a result of this, reliable hardening of the connecting elements occurs, which, in turn, forms a reliable waterproof layer. This paint dries within 2-3 hours at a temperature of 18-22 degrees Celsius. As a result of finishing work, a wonderful, semi-matte layer of paint is obtained.
Application area polyvinyl acetate water-based paints huge. They are used for interior and exterior work in residential, industrial and commercial premises. In general, such paints will work in the countryside too. PVA paints can be applied to concrete, wooden surfaces, as well as those that were previously covered with oil paints or plaster.
In general, the quality of these paints depends on the amount of polymer binder in the paint base. However, there is a standard list of advantages of polyvinyl acetate water-based paint:
This list shows only some of the advantages of such paints, which are considered basic. Different types of PVA paints have other advantages that will be useful when decorating various rooms.
Don't know what paint to choose for renovation? Are you confused by the names of compounds that are similar in purpose? I will tell you what water-dispersion paint is, what types it comes in, and what properties it has. I am sure there will be no more secrets for you.
What does the word "variance" mean? It is a mixture of small particles suspended in a liquid medium.
In the case of paint, dispersion refers to a mixture of polymers and pigments that are evenly distributed in water. Unlike oil, pentaphthalic and other paints, these particles are not dissolved in a solvent (water). As a result, the dispersion is easy to separate from the dispersion medium, i.e. water.
The whole principle of water-dispersion paints is built on this:
This is the secret that water-based paints can be completely waterproof after application. True, not all of them have this quality.
What is water-based paint, which is so often compared to water-dispersion paint? This is an emulsion made from water, pigments and small particles of polymers.
In other words, water-dispersion paint and water-based paint are different names for the same paint and varnish material.
Where then do comparisons of the same material come from, and why are different characteristics given? The thing is that water-dispersion paint includes a whole group of different paints and varnishes, differing in the type of polymers, additives, etc.
Therefore, with similar comparisons:
Regardless of the type of polymer, all water-dispersion paints and varnishes have some common qualities:
Many beginners, when performing painting work, make one serious mistake - due to the relatively low hiding power of the paint and varnish material, they try to apply it in a thick layer. In reality, the paint should lay down in a thin, uniform film. If necessary, it is better to increase the number of layers, but not the layer thickness.
The remaining properties depend on the type of paint, so let’s take a look at them below.
I will say in advance that all comparisons of these paints are very conditional, since the properties largely depend on the brand of the paint and varnish material, or rather its composition, and not the type of polymer. Thus, acrylic paints from some manufacturers can be much more expensive and of higher quality than latex or silicone paints from others, although the former are traditionally considered to be of lower quality and cheaper.
Therefore, advice to use acrylic, silicone or latex paint in a given situation is not correct in advance. But, nevertheless, the type of polymer still affects the properties of paints to some extent. Therefore, next we will get acquainted with their main qualities.
Paints based on polyvinyl acetate dispersion are the exception when, regardless of the manufacturer and brand, the properties of the coating are approximately the same.
Advantages. The main advantage of these paints is their low cost. They are cheaper than even relatively inexpensive acrylic coatings.
Flaws:
Therefore, polyvinyl acetate coatings are usually used only for painting in dry rooms. Moreover, they are extremely rare to find on sale lately.
Price. The price starts from 40-50 rubles per kilogram.
Dispersion acrylic paints are the most popular today, as they have good characteristics, and at the same time they are usually cheaper than other water-dispersion coatings.
Advantages:
Flaws depend on specific brands. Water-based acrylic paint may not be sufficiently resistant to moisture, abrasion, etc. Therefore, when purchasing, you need to pay attention to the characteristics.
Price:
Latex-based paints have recently become widespread. True, to real latex, i.e. rubber juice, they have nothing to do with it. In this case, manufacturers call modified acrylic latex, which differs from regular acrylic in its increased elasticity.
Advantages:
Otherwise, the qualities are the same as those of acrylic coatings. In particular, they can be used for both interior and exterior work.
Flaws. The only disadvantage that should be highlighted is the higher cost compared to acrylic compositions.
Price:
Silicone paints and varnishes are the most expensive and high quality.
Advantages:
Price:
Flaws. As with latex paint, the disadvantage is the high cost.
On sale you can find acrylic-latex, latex-silicone and other similar types of paints. However, these terms are usually a marketing ploy and do not provide any information about the properties and characteristics of the coating.
Finally, I repeat that when choosing, pay attention first of all to the characteristics of the coating, and not to the type of polymer indicated on the packaging.
Now you know what waterborne paint is and where it can be used. Additionally, watch the video in this article. And if you have any questions, write them in the comments, and I will be happy to answer you.
Now water-based paints are gaining popularity. This is due to their practicality and low cost. In addition, it is easily applied to a cleaned surface, so even a beginner can use it. The material does not have such an unpleasant odor as others, so it can be used for interior work quite safely. Its use will not cause any discomfort. From this article you can find out what types of water-based paint there are, and what are the characteristics of each.
The water emulsion contains components such as latex, antiseptic, fillers and thickeners. The material consumption is not too large and amounts to 250 grams per 1 square meter. Sometimes it may be necessary to apply several layers. Their quantity depends on how susceptible the surface is to absorption.
Viscosity varies depending on the method in which the product is applied to the surface. If water-based paint is applied to the surface with a brush, then its viscosity is 40-45, but if a spray gun is used for work, then this indicator varies between 20 and 25.
The coating dries within 20 hours, but sometimes this figure may be less. The jar of water-based emulsion should be stored away from sunlight in a cool place.
Water-based paint has become highly in demand due to the following qualities:
But all these qualities are available only in the material that meets the requirements of GOST.
Since they contain a variety of polymers, all water-based paints can be divided into several types:
Consumers, in view of such a huge variety, have a fair question about choice. Next, all these types will be considered from the point of view of application and the presence of disadvantages.
Water-based polyvinyl acetate paint is perfect for all interior work, be it painting walls or ceilings. The basis for it is PVA.
The main advantages of this type are:
Along with a lot of advantages, there are disadvantages that can be identified if used incorrectly:
Important! You cannot use PVA paint on metal surfaces.
Its consumption depends on the shade: light color will need 250 grams per 1 square meter. m, and dark 150 grams for the same area.
This type of finishing material is produced in accordance with GOST, but it is also possible to voluntarily certify the material, but only in accordance with the existing GOST. In any case, the manufacturer must have a certificate for water-based paint of this type.
This type is a solution of liquid glass with all kinds of additives. It is suitable for both indoor and outdoor use. Silicate water emulsion is resistant to changes in temperature and humidity, and has a long service life without constant updating.
This type is mainly used for painting wet rooms inside the house, as well as the facades of buildings that are exposed to groundwater. The coating is breathable with high vapor and air permeability.
This type of water-based emulsion occupies a leading position in the construction market, since the acrylic resins included in its composition have a number of advantages. But acrylic paint is noticeably more expensive than all other types.
Features of water-based acrylic paint:
Now they also produce analogues of similar quality, but noticeably cheaper: styrene acrylic, vinyl acrylic and acrylic silicone solutions. A small visual announcement of the material can be viewed at the link:
This type is perfect for any damp room or where constant wet cleaning using sponges and brushes is necessary. This coating is resistant to regular brushing, which is possible thanks to the use of latex in the production.
Latex water-based paint is the most expensive among water-based paints due to its water-repellent properties, but at the same time good vapor permeability. In addition, such compositions are capable of bridging small cracks on the surface, which can eliminate preliminary leveling.
Silicone also has similar properties to latex, due to the presence of silicone in the composition. Such paints actively fight fungus, which often appears in damp rooms, and prevent its reappearance.
Separately, we can highlight another type of water-based paints, which is gradually becoming less and less popular - these are mineral ones. They include cement or slaked lime. The main purpose of such compositions is painting concrete and brick surfaces. The main disadvantage of this type of water-based paint is its relatively short service life.
Since the production of water-based paints does not require the use of complex mechanisms and rare substances, many manufacturers appear who, taking advantage of the ease of production, produce low-quality products. The main rule when choosing this product is a manufacturer who has been producing for a long time. Tex water-based paint is very popular; it has received a lot of positive feedback from repairmen and simply those who carry out finishing repairs on their own. Such products have a GOST certificate of conformity.
The jar must have a mark indicating that the material complies with GOST. This is an indicator that this finishing material is not a fake and its production was carried out under strict control.
The choice of material for a certain type of work is carried out according to the markings on the container. First, the can is abbreviated as water-dispersed (WD), after these letters there is a designation of the polymer that is in the composition, and the number after it just indicates the purpose of the product:
Among the variety of finishing materials on the construction market, you can get confused. But, if you have chosen water-based paint, then after reading this article, you can learn about its types and the scope of work for which this or that type is intended. Water-based paint is an excellent solution for both exterior and interior work. You just need to choose the right type, carefully studying the composition and the information indicated on the packaging.

For painting the ceiling, floor and external work, it is advisable to use water-based paint or, as it is popularly called, water-based paint - an inexpensive, environmentally friendly painting composition. This article will discuss the types of water-based paint, their characteristics, use, advantages and disadvantages.
Any renovation is not complete without painting the walls and ceiling. Also today, facade painting works are becoming more and more popular. We have already talked about painting with water-based paint, where you will find detailed technologies for performing the work and video instructions.
Paint is a water suspension of pigments, polymers and various fillers. After its application, the water evaporates, and thanks to the polymers included in the composition, a thin coating is created. Basically, the use, properties and price of paint depend on its type.
The main types of water-based emulsion: polyvinyl acetate, acrylic, latex, silicate, silicone. Despite the small variety, buyers often ask the question: “Which water-based paint is better?” Let's look at the main types and characteristics of water-based paint.
Water-based polyvinyl acetate paint is the cheapest and highest quality. It is made on a PVA basis and is only suitable for interior work, such as painting walls and painting ceilings. It is inexpensive, which is what causes its popularity.
Advantages of polyvinyl acetate water-based paint:
Flawspolyvinyl acetate water-based paint:
As for paint consumption, per 1 m2 you will need no more than 250 g of light-colored paint or 150 g of dark colors.
Domestic companies produce polyvinyl acetate paints in accordance with GOST 28196-89, and the law also allows voluntary certification of paint for compliance with this GOST. The price of polyvinyl acetate water-based paint is from 50 rubles. for 1 kg.
Among all types of water-based paint, the leading position in quality and popularity is occupied by acrylic paint, made on the basis of acrylic resins, which are very durable and elastic, but also very expensive. There are also cheaper analogues on the market based on vinyl acrylic, styrene acrylic and acrylic silicone acrylic copolymers, but they are also inferior in quality.
Features of acrylic paints:
To ensure that the surface is washable and not exposed to moisture at all, latex is added to water-based paints. The paint can withstand 5,000 brushing cycles, but regular paints can only be wiped down infrequently. Therefore, it is suitable for painting walls in the kitchen and bathroom. This is the main advantage of latex paint compared to other types of water-based paint.
It is also important that the water-repellent effect does not interfere with vapor permeability. This is a subtype of acrylic paints, which is the most expensive. The advantage lies not only in good water-repellent properties, but also in the ability to bridge cracks (two layers cover cracks up to 1 mm), due to which pre-treatment with putty is not required.
Popular washing paints from the following manufacturers: Expert, EcoDom, DALI, Premiere, Alpalux (ALPA) for interior and exterior work based on acrylic resins and copolymers. You can find out about the leaders in this market, their products and prices in the article Manufacturers and price of water-based paint.
Silicate water emulsion is an aqueous solution of liquid glass with the addition of colored pigments. Suitable for painting almost all surfaces, it has a high degree of adhesion, is resistant to high humidity, temperature changes and other atmospheric phenomena.
Features and use of silicate water-based paint:
The composition of all paints is practically the same - it is the astringent part (glue, etc.), filler, dye and various additives in small quantities. The binder part is added depending on the use. For example, oil paints are made on an oil base, and water-based paints, naturally, on a water base.
Making water-based paint yourself is quite simple. You will need:
Dissolve the glue in water, add soap solution and chalk to it, mix the mixture until a homogeneous white mass is obtained. Dye is added if necessary. Consistency and viscosity are determined by eye. It is necessary that the resulting mixture lies evenly on the walls and is not too thick. To ensure greater plasticity, glue and soap solution are added. Before applying to the walls or ceiling, the paint is filtered.
Water-based paints are safe to use, environmentally friendly, and do not harm health or the environment, especially homemade paints.
