Construction work related to building facades and interior work requires the use of quality materials. For painting various surfaces, coloring compositions are used, which are presented in a wide variety by manufacturers of paints and varnishes. They differ in their properties and characteristics, each type has its own characteristics, advantages and disadvantages.

What it is?

When purchasing dispersion paints, it is very important to know what kind of composition it is, for which work it is recommended for use, and what are its main advantages and disadvantages.

VDK today is a very popular material, since with such compositions it is very easy to process floors and furniture, various barriers and facades, decor items, as well as ceilings and walls inside buildings. The products are perfectly applied to brickwork, concrete, metal and wood.

VDKs appeared on the market recently, but have already gained popularity due to the durable and attractive coatings that are obtained as a result of using these dyes. However, the surface acquires an ideal and attractive appearance only if the VDK is correctly applied and the working area is properly prepared.

Water-dispersion compositions are a dispersion of solid synthetic polymers in water. Most often, products are produced in the state of a liquid paste, which is diluted to the required density before use. As a result, for work, specialists get a liquid of a transparent or opaque type, visually similar to milk. After surface treatment, the water evaporates, leaving a thin and hard layer of polymers at the treatment site.

The paint is made up of many components. Its main components are:

  • Special additives - this is a large group of substances, among which there are thickeners, emulsifiers, ethylene glycol and other components.
  • Coloring pigments, thanks to which the composition is given the necessary color.
  • Film former - these are the components with which the polymer layer is formed. These constituents contribute to the adhesion and strength of the coating.
  • Excipients - marble chips, talc, as well as a number of natural and artificial materials. They are responsible for obtaining a matte, satin or other surface.

VDK is a safe and environmentally friendly product that is very easy to use, odorless and fireproof. Dispersion paints are often used as well as water-based paints.

Some experts mistakenly believe that there is no difference between the two. However, the main differences between the compositions in terms of quality lie in the characteristics of these two compositions - moisture resistance and colors, as well as in the polymers they contain.

Advantages and disadvantages

The technical properties of water-dispersion dyeing compositions occupy a leading position among other types of paints, and also significantly outperform materials based on organic solvents in their characteristics. Among the main advantages of VDK are the following properties:

  • ease of application of the product;
  • harmlessness and safety, including fire safety - they are ensured due to the complete absence of natural solvents in the substance;
  • mechanical strength;
  • excellent adhesion to various materials;
  • fast drying - usually the surface does not stick after an hour or two;
  • color and texture stability;
  • a large selection of shades;
  • durability of the coating;
  • vapor permeability, which makes the surface breathable.

The opinion that water-based products can be washed off with it is wrong. However, VDK have different resistance to humidity in rooms, therefore, in rooms such as a bathroom or kitchen, it is necessary to use only moisture-resistant products of this type.

Some experts highlight certain properties of the paint, positioning them as the disadvantages of the coloring composition:

  • The technology of painting with such materials requires compliance with the temperature regime - the thermometer indicator should not fall below 5C with a humidity of no more than 80%. Under other conditions, the film does not form: at a lower temperature, it will burst, and at high humidity values, the composition will not dry out.
  • Storage conditions assume a room temperature from 0 to + 30C.
  • Water-dispersion compositions form a thinner film than solvent-borne ones - as a result, the surface for painting must be carefully prepared for work.
  • The composition, which has not yet dried, must be protected from possible precipitation on the first day after painting.
  • If the air temperature is too high, and the dye is exposed to ultraviolet radiation, the dispersion will dry out ahead of time, which is fraught with stains on the surface.

The disadvantages of water-dispersion paints include their high price. But the opportunity to save on materials for its cultivation and cleaning of the instrument allows you to justify their cost.

Specifications

The properties possessed by materials determine the quality of paints and varnishes. Water-dispersion products have the following characteristics:

White. Products for the treatment of facades and coloring compositions for interior finishing works are produced in white, and the required shade is created immediately before the start of painting. The saturation of the final color, the formation of which occurs with the help of coloring pigments, will directly depend on the level of whiteness. Titanium dioxide is responsible for the quality and brightness of shades and colors

  • Hiding power… Responsible for the amount of consumable composition. It is considered the norm when 1 liter of paint weighs 1.5 kilograms. A product with a lower density contains more liquid, and conversely, a high density indicates that a large amount of filler has been added during the manufacturing process. High and low density have a negative effect on the hiding power of the composition.
  • Resistant to moisture. This characteristic determines the area in which the composition will work. Dispersion products can be designed both for interior painting, that is, act as interior products for processing, and produced for outdoor use. PVA has a minimum moisture resistance indicator. Other formulations, including water-dispersible acrylic products, have good resistance to high humidity levels and a variety of surface cleaning options.
  • Light resistance - it is an indicator responsible for maintaining an attractive appearance of a coating that is exposed to ultraviolet radiation. Polyvinyl acetate compositions practically do not fade. Latex compounds are recommended for surface treatment in dark rooms.

It is very important to select a coloring composition based on the scope of the product. For example, basements can be painted with latex materials, as in the sun it will quickly lose its color, but in such rooms they will provide the surface with a strong and reliable coating.

Acrylic compounds are best used as a facade material for painting.

Views

Since the scope of application of VDK is very diverse, there are several types of products that differ in their properties and components that make up the composition.

There are three main groups of material:

Polyvinyl acetate dispersion. Products of this type are inexpensive, the paint retains its original appearance well, but the coating is very unstable to moisture. Recommended for walls and ceilings in rooms with low humidity levels

  • Acrylic products. This group is represented by the most expensive formulations, the high price of which is justified by their versatility in the field of use. Acrylate compounds perfectly retain their color when exposed to sunlight. The washable surface is resistant to abrasion and temperature fluctuations. The paints have a good indicator of elasticity, therefore they can easily cope with painting over cracks with a width of no more than 0.5 mm. Thanks to surface treatment with such material, it acquires a glossy or matte appearance.
  • Styrene butadiene formulations are latex materials with an average cost and excellent water resistance. The disadvantages of paintwork materials in this group include poor resistance to negative temperatures. The compositions showed themselves well when processing surfaces in rooms with a high level of humidity, but they are not intended for facade work, since they have low resistance to light - under such conditions they quickly turn yellow.

Scope of use

The scope of VDK is quite large and directly depends on the type of material.

Most often, such paintwork materials are purchased for painting the external and internal elements of the building. The products have shown themselves perfectly when working on wood, they paint concrete and metal bases well, and are used for lining. Before applying the composition, you must first prime the work surface with a brush or rubber roller.

This paint is also used for treating tree trunks, which provides excellent protection against insects, rodents, high and low temperatures.

How to choose?

Going to the supermarket for paint, you need to determine the conditions in which the coating will be used.It can be a room or external surfaces of a building, temperature and humidity can be high or low, the level of illumination can be strong or weak.

It will not be superfluous to take into account the requirements for the coating - resistance to the occurrence of fungus, the interior component, vapor permeability, as well as the type of work surface.

Storage rules

When purchasing water-dispersible materials, you should be sure that they are stored under the correct conditions.

During storage, care must be taken to ensure that the paint does not freeze and overheat. Water-dispersive products should be stored at temperatures from 0 to + 30C.

It is worth protecting yourself from getting the coloring composition in the eyes and on the face, therefore, before opening the paint, you must wear glasses, and apply a protective cream to the skin.
