Aqueous emulsion polyvinyl acetate paint is one of the most popular and popular in the construction market. She fell in love with customers thanks to a huge set of positive qualities and advantages, which will be discussed today. We will also talk about the negative points, minuses, GOST, certificates of conformity, parameters and characteristics of the product.
The choice
Having heard competent advice, lay people in the paint business rush to the construction market for water-based polyvinyl acetate paint. The right choice, but before buying, you must definitely pay attention to several important points. Of course, the cost of building materials plays a huge role when choosing a buyer, but other criteria should not be discounted, namely:
- viscosity;
- ease of application;
- structure;
- shelf life;
- storage specifics;
- consumption.
Structure
Considering the characteristics of a water-based polyvinyl acetate paint, one cannot but address the issue of composition. Some experts call such building materials “oil in water”. The paint contains the following components:
- emulsion (polyvinyl acetate);
- plasticizers;
- stabilizers;
- coloring pigment.
Many beginners confuse water-based paint with water-dispersible. In fact, choosing a product in the construction market or in a store, you can accurately take any paint. This is almost the same thing, the principle of "work" is the same. The paint is applied to the prepared surface, then the water component evaporates and disappears, and the coloring elements harden and remain on the wall, forming a beautiful evenly painted area.
Advantages
Polyvinyl acetate water-based paint is widely used by experienced painters for painting walls and ceilings indoors. It has a number of advantages and positive technical characteristics that make it practically indispensable and explain the consumer's love for it:
- The unpleasant smell of paint, which is given by many other types of paints and varnishes, is practically absent here.
- In the composition you will not find any harmful substances, "smelly" solvents, etc.
- This is a fireproof wall covering.
- Stoically tolerates mold and mildew.
- It has increased resistance to alkalis and acids.
- In contact with the sun will not quickly fade. Even if you decide to paint the walls in a sunny room, do not worry. You can safely buy a water-based PVA paint and paint it for children and even the kitchen.
- Such paints have an increased "tenacity" and are in excellent contact with the painted surface.
- Using a special tinting paste, you can make absolutely any shade. Moreover, the colors can be modulated and created by the buyer. You do not need to contact specialists for this. The case is simple, understandable, saving money. For the base, as a rule, white paint is taken, into which color is already added. It is desirable that he was the same company as the paint itself. Stirred, applied to the wall.
- It is highly soluble in water. If necessary, it is diluted with plain tap water to the desired consistency. No need to splurge and purchase special solvents and thinners.
- The composition can be applied to drywall and concrete.
- After the coating dries, an incredibly smooth, flexible, even ink film forms on the wall. The walls covered with water-based polyvinyl acetate paint look very impressive and beautiful.
disadvantages
If you find a high-quality water-based polyvinyl acetate paint, there is a certificate of conformity, all expiration dates are set, then it will have all of the above set of positive characteristics. However, experts still highlight several disadvantages of this painting building material.
Firstly, this type of paint can not be used for outdoor applications. Unfortunately, it is not intended for outdoor work. Secondly, it is used exclusively in dry rooms for painting walls or ceilings. For a bathroom, bath room, sauna, etc., water based paint will not work.
If you plan to apply on a wooden surface, then you will first have to spend time and prepare a “rough” layer. The tree will need to be sanded and cleaned. Otherwise, the surface will not only “eat” a huge amount of coloring matter, but the pigment will not be so pronounced (the paint will be faded, unsaturated).
Certification
When buying, it is recommended that you require the manufacturer or seller to have a certificate of conformity. In this case, the polyvinyl acetate aqueous emulsion ink will be of high quality. Building materials will possess all of the above set of positive properties and characteristics. If the seller does not have a certificate and any other documents for the paintwork, it is better to refrain from such a purchase and go to another store.
Despite the fact that the law allows voluntary certification of paint and varnish building materials, bona fide manufacturers will always manufacture their goods in accordance with accepted standards. GOST water-based polyvinyl acetate paint - 28196-89.
Price
Repair is, of course, quite expensive. However, water-based paint is not such an expensive building material, and we would not recommend saving on its acquisition. How much does a standard size jar of paint cost? One kilogram of the coloring composition costs the buyer fifty-five rubles (the cheapest option that they managed to find) and more.
Of course, the cost of paint will gradually increase, as each time new additives used in its production become more expensive. This is a normal process, which is not unique to building materials. Refuse to purchase high-quality paint with a wide range of positive technical characteristics is not worth it. Experienced painters argue that only water-based paints can help to realize even the most daring design ideas and solutions.
