Deposited on the wall surface, it creates a continuous film which has excellent adhesion to most finishing materials.

Primer consists mainly of organic resins and adhesive components. Film formation occurs due to silicate polymers, latex, acrylic or silicone. The solution also contains additives impart greater plasticity or fluidity.

Manufacturing companies are required to indicate on the packaging of a number of parameters that the user needs to know:

1. The order of preparing the mixture and its ratio.
2. The average consumption of the drug per 1 m².
3. The manner in which material is recommended to apply on the primed surface.
4. Time, during which will be completely dry layer deposited on the wall.
5. Guaranteed by the expiry date and the date of production of the mixture.

Under the bright wallpaper is better to choose a transparent primer

According to the generally accepted rules, the primer must have properties that are necessary for its immediate purpose, namely:

• in the surface that is treated, the composition must penetrate very deeply;
• adhesion adjoining materials using primers should become much higher;

• Any primer is simply obliged to have antiseptic and antifungal action;
• quick drying - an indispensable attribute of any high-quality primer.

• the coating material. After all, plaster, concrete, plasterboard and other grounds totally different properties;
• level of humidity in the room where you plan to apply the primer;

Purpose primer mixtures

The solution penetrates deep into all the pores of the wall, holding them and forcing out the air, which prevents the formation of bubbles under the wallpaper. surface disinfection takes place by the fact that the primer composition has a substance which is capable of striking the living organisms: fungi, mold and bacteria. The primer creates an excellent adhesion between the wall and wallpaper. This is especially true in the various joints and corners.

In this case, atmosphere in the housing is not disturbed, as the walls do not stop "breathe" after using primer mixtures.

What are the main types of primers

At present agreed that all primers according to three criteria: the solubility of the material used and the appointment. If you take the solubility test, the chemical industry offers the following primers:

1. Organic solvents dissolves: alkyds, polyurethane latex.
2. There are water-based acrylic, silicate, silicone and latex primer.
3. On the basis of natural minerals such as gypsum, cement or lime.

Walls are primed after plastering and spackling

Useful advice!Totally unacceptable handle silicate primer surface containing gypsum. They are not designed for this purpose and lead to loss of strength properties.

As intended all primers are divided into several separate types:

• universal application. They produced a water-based;
• have a specialized purpose: antifungal, antibacterial or anti-corrosion;
• preparations to 15 mm deep penetration into the surface;
• having insulating properties;
• so-called betonkontakt, allowing to provide the best adhesion to concrete surfaces.

The primer is easily applied to the wall with a roll

Primer walls before gluing wallpaper is usually carried universal alkyd, latex, acrylic primers or conventional wallpaper paste.

How the effects of various kinds of primer mixes

Consider a method of using a particular type of soil. Acrylic primer applied to the wall using a roller. Where this is not possible, use a brush.

Wallpaper glue can only be after so primed the walls dry out

Latex is often used to group crumbling surfaces because it can bind particles of the substance. Alkyd primers create a moisture proof film and destroy the mold. Property block rust allows this type of primers used on concrete surfaces.

Generic types are suitable for any surface, making them the most popular. However, it is not necessary to put them on a crumbling wall. It is better to choose a more specific type of soil. Priming of walls before mounting your universal primer ensures that all work on the quality requirements are met.
