Water-dispersion paints for outdoor and internal works

Water-dispersion paints for dyeing various surfaces are becoming increasingly popular. They are used not only indoors, but also for external work. Paint is distinguished by an eco-friendly composition, efficiency and high passing abilities, which contributes to the expansion of its application.

What it is?

Water-dispersion paint is a multicomponent mixture for staining surfaces from different material. The characteristic feature of such paints is that water is the diluent of coloring substances.

The dispersion paints may include a different number of components, but the basis is the following:

  • Substances forming a polymer film on the surface and binding all components (polymers: Styrene, Acrylic, Latex);
  • Pigment substances, thanks to which the desired color is obtained;
  • synthetic or natural fillers that attach the basic properties of the coloring composition (minerals: talc, calcite, mica, chalk, marble powder);
  • Special technological additives to improve texture and storage of the mixture. Adding ethylene glycol contributes to the population of frost resistance. The composition includes preservatives, antiseptics, emulsifiers and thickeners.

Water dispersive paint sold in the form of pasta of different consistency. Clean water is added clean water in the amount required for applying a roller, brush or paint to the painted area. As the added water is drying, it evaporates from the surface, as a result of which the steady protective film is formed.

Advantages and disadvantages

To choose any building and finishing material, consider the pros and cons when applying and operating.

The advantages of water-dispersion painting mixtures include the following:

  • There is no sharp chemical smell;
  • eco-friendly;
  • fire-resistant;
  • low drying time when applied to the surface;
  • just working with paint;

  • Parry permeability of painted walls and facades;
  • abrasion strength and resistance;
  • The service life of the painted coating is from 5 to 15 years;
  • high degree of adhesion when painting;
  • paints are in the available price category;
  • Moisture-resistant brands provide high-quality protective coating from water;
  • Large color gamma. Self-color can be given using a kolacher.

A large number of positive properties of water dispersion exceeds flaws. The minus is the loss of quality characteristics during storage and transportation at very low temperatures. Dispersion paint can not be cooled and freeze. This implies that staining is impossible at low temperatures. To paint outdoor designs, you need to choose the time when there is no precipitation, the temperature will become acceptable, and weather conditions will allow you to start work, let’s completely dry the paint layer. Before painting, carefully prepare the working area, because water-dispersion formulations cannot hide visible irregularities and disadvantages of the surface.

Types and characteristics

Many species of water dispersed paints are produced, so the area of ​​their use is very wide. In terms of resistance to moisture, water-dispersion solutions are divided into washable, unstable to moisture and moisture resistant.

The disperse mixture is divided by the main component of the polymer component:

  • polyvinila acetate;
  • acrylate;
  • latex or butadiene-styrene;
  • silicone;
  • Dispersion-silicate.

Component in PVA mixtures performs polyvinyl acetate, which does not tolerate humidity and is easily washed off. Such cheap mixtures are suitable for staining ceilings of dry rooms or bedroom walls. Acrylate dispersions contain acrylic, which is characterized by moisture resistance, strength to mechanical effects, resistance to sunlight without color change. Unlike PVA, these materials are expensive.

The mixture with acrylic is classified as intended:

  • interior.
  • Facade.

Acrylic compositions are universal in use. This means that they are used for internal and outdoor paintwork. Interior type painted walls and ceilings of residential premises, offices. For the external finishing of facilities use facade compounds having atmospheric resistant properties.

Acrylic paint can be washing, as well as subjected to dry mechanical cleaning. According to the type of painted surfaces, compositions for plaster, wood or metal.

Latex paint similar to its properties with acrylic composition. The difference is that latex turns yellow under the influence of ultraviolet, so it is not used for staining the external details of the structure and premises where direct sunlight penetrates. The type of latex mixtures is rubber paint with an elevated content of latex, which has the properties of rubber when applied in 2-3 layers. It creates an elastic durable layer that is not afraid of abrasion, water, high and low temperatures.

It is used as protection against atmospheric precipitation of iron roofs, Andulina, slate, concrete. The material perfectly showed itself as the facade decoration of concrete buildings, wooden buildings, fences.

In the market of paintwork products recently appeared latex mixtures with adding Vinyl-Versatat. This substance gives sustainable fire qualities. On its basis, flame retardant painting materials are manufactured. An intermediate link between acrylic and latex compositions is acrylate latex. Latex and styrene mixing allows you to change the final product price, and improve quality. The price of such blends is lower compared to a purely acrylic material.

Water-dispersed silicone paint with silicon resins can paint any material, Since Silicone masks the defects of the coating. It is possible to apply to a wet surface: so, high quality characteristics allow painting rooms with high levels of humidity, producing external decoration of buildings. A feature of silicone paint is its ability to not absorb dirt and dust, providing cleanliness during operation. Silicate compounds are made with the addition of liquid glass, so they acquire especially strong properties. Ideal for staining facades, creating a high density protective coating. Crab can only be mineral surfaces: concrete, clay, plaster, gypsum.

All the production of water dispersion mixtures is regulated by GOST.

When choosing products, these technical characteristics are evaluated:

  • Colour. Color characteristic has an important decorative value. Initially, the mixture has white color thanks to the pigment titanium dioxide. The desired shade is achieved by making a sole. Than a white-white dispersion first, the richer to get the right color.
  • Uniformity. In the diluted solution there should be no clots and solid particles. When applying should form a sleek layer.
  • Wear resistance. This operational characteristic depends on the strength of the finished layer
  • Flow consumption. An important parameter that depends not only on the surface of the surface, but also on the quality of the feedstock, from the density of the solution. Good shelterness is usually different solutions that, with a volume of one liter weigh half a kilogram. Middle flow of dispersion compositions – 130-180 g / kV. M. Approximate flow indicate the label.

  • Moisture resistance. The degree of moisture resistance depends on which formulations can be applied under different humidity conditions.
  • Resistance to light. The appearance of the coating depends on the light resistance. Resistance to ultraviolet is determined by the composition components. Acrylic and polyvinyl acetate well tolerate the effect of light, they will not burn out.
  • Frost resistance. The resistance parameter to low temperatures is determined by the number of freezing cycles.

Manufacturers

In the domestic building market, water-dispersion paints are represented by Russian and foreign manufacturers. Among foreign companies engaged in the production of dispersed emulsions, German companies DUFA and CAPAROL, Turkish company Marshall, the oldest Finnish company Tikkurila, Slovenian manufacturer Belinka, the Polish firm “Snowball”, the British ICI concern, producing a Dulux brand. Also Luxens Brand, designed by Lerua Merlen, has numerous positive feedback. They offer high-quality painting materials, as well as a large range of other products produced. Dulux, Caparol and Dufa paints belong to the premium price segment.

Materials of foreign manufacturers are not always better, because often in domestic production use European raw materials for the manufacture of dispersion emulsions. For example, the German concern DUFA has established the production of paint products in Russia under Trend Farbe brand, which reduced the cost without losing German quality. If we talk about the ranking, then foreign analogues are valued above Russian.

Among the Russian manufacturers, the products “Tex”, Aqua, Lacra, Krafor, Oleet, Krakoff are widely represented. Painting materials under the brand “Tex” occupy a leading position in the market, since they produce products of acceptable quality at an affordable price. “Leningrad paints” represent the economy segment of the market. Krasooff Pro company produces a wide range of coloring materials for different types of surfaces. Empils manufactures Oleet and Newtone based on acrylic, latex and silicone.

The company “Concord”, producing trademark “Ecopol”, produces professional water-dispersion pastes for construction and finishing. In addition to the well-known manufacturers that implement paintwork products on the Russian market, there are a large number of minor manufacturers focused on the regional market. For example, the SUR Painting Enterprise Group produces Grafics and Svetlitsa dispersion emulsions that are in low price category.

How to choose?

What paint pick up for staining depends on the room itself and the conditions of operation of the surface.

When choosing water disperses, pay attention to such criteria:

  • view of the painted surface;
  • manufacturer;
  • The popularity of the brand;
  • Conditions of operation of the finished coating: the effects of temperatures, moisture, light;
  • certificate of conformity of quality;
  • shelf life;
  • Compliance with storage and transportation conditions.

Dispersion mixtures are selected taking into account the type of surface. Sell ​​solutions for wood processing, metal, concrete. They include additives that improve adhesion with a specific type of material. This information is indicated on the package. The composition for wood is suitable for staining of wooden doors, windows, lining, facade of boards, protect the bark of trees from rodents. Mixtures for concrete choose for mineral coatings: plastered walls, concrete panels, bricks. Coloring solutions for metal create a protective layer on metal structures and parts. Water dispersion paints can be applied to enamel from acrylic.

Of great importance when choosing paints and varnishes are given to the manufacturer and fame of the trade brand. The quality of Russian manufacturers is lower than that of foreign, due to quality standards. It is worth studying the reviews of consumers, and in the future to give preference to the trademarks proven from the positive side.

For internal works, all types of water-dispersion compositions are used. For rooms, the windows of which go to the north side, choose latex paint. It is suitable for staining the walls of corridors and hallways. For light, frequently visited rooms or kitchen and dining areas, pick up the composition with acrylic. Ceilings worth painting in an inexpensive polyvinila acetate mixture.

When staining outdoor designs, the choice drops on acrylic facade paint. It has the necessary operational properties, resistant to negative atmospheric phenomena. The composition is applied in several layers to achieve the necessary protective functions. Rubber paint has a high degree of protection, creating a vapor-permeable elastic cover. Silicone and silicate compositions are expensive, but fully justify their cost, fencing the surface from water and premature destruction.

According to the degrees of shine, the glossy or matte paint is selected. The choice is carried out depending on the interior and the function of the room. The glossy surface is demanding of the draft finish, because all defects are visible on it, but the gloss is worse dirty and easier. Glitter gives a special atmosphere room. Matte solutions have better collapse, give a saturated color.

On a bank or bucket with paint, it is necessary to find information about the production date and storage period. It is impossible to buy an overdue product. It is not suitable for use. Large trading points have the ability to store products in proper temperature conditions. In smaller construction departments, it is worth noting about the conditions in the warehouse. If it is free to freeze the composition, it will be lazy. Poor to score a surface.

Sometimes the decisive criterion is the price. In this case, pay attention to the inexpensive brands of domestic manufacturers. You can choose a mixture based on styrene with the addition of latex, which will reduce the price not to the detriment of wear-resistant and light-resistant characteristics. The choice can be made independently based on the information studied. It is also always possible to obtain recommendations from a consultant in the construction department.

In the next video, you will get in view of the review of Simphony water dispersion and tips on their choice.
