This building material helps create reliable adhesion of the upper layers of the coating. In addition, such a construction process performs various functions. For example, it helps to protect metal materials from corrosion, wood from rotting, closes pores, defects of the painted surface.

The primer helps to create the most reliable base on which you can safely glue the wallpaper. With this special composition, the wallpaper holds firmly, smoothly and reliably.

In addition, it helps to fix the top layer of plaster, prevents the appearance of cracks. A special ready-made mixture increases the service life of any coating, and also helps protect the walls from mold. Most primers contain an antiseptic that prevents various pests.

Primed surfaces establish subsequent layers more efficiently and smoothly. In addition, the use of the material significantly reduces the cost of expensive paint, and also makes it possible not only to smoothly and smoothly glue the wallpaper, but also to apply the paint in an even layer.

Kinds

The composition of the primer is divided into the following types:

• acrylic;
• alkyd;
• glyphthalic;
• perchlorovinyl;
• polystyrene;
• polyvinyl acetate and others;

Acrylic compounds are the most common and in demand. They are universal, so they are used in various fields of construction and repair work. One of the main advantages of this type is the complete absence of a specific smell.

Alkyd species are best used for woody substrates, as they help protect the surface of the wood from harmful effects. Thanks to this primer, this material retains its quality characteristics, and becomes suitable for further operation.

For dry surfaces, glyphthalic options are used. The primary layer of this kind dries in two days. It is customary to apply perchlorovinyl appearance on metal and concrete surfaces. The primer can be divided into various types also by application.

This finish makes it possible to significantly increase the strength and reliability of the surface with the applied materials. Modern decoration for wallpaper makes it possible to significantly save on wallpaper glue. The better the mixture, the more reliable and durable it will be. putty layer.

There are also mechanized special tools with which you can achieve the highest quality result.

Many people care about the question - what should be the primer consumption per 1 m? Correct calculations depend on the type of surface. For example, to apply the mixture to a porous surface, such as concrete, sand concrete or brick, you need to use up to 0.5 kg.

Before applying the finishing mixture to such walls, it is necessary to carefully treat the surface by impregnation of deep penetration.

If you are going to apply the finish to the walls of medium porosity, then you should apply up to 0.35 kg of the primer mixture. For a non-porous surface, a mixture of up to 0.25 kg is required. The method of applying the material depends on the surface of the walls. If the building material is completely absorbed, then you will have to apply another layer.

After this, you can already start applying the mixture. You need to work from top to bottom. After you have applied the first coat, you should wait until it is completely dry, and then proceed with applying the second coat.

Under the liquid wallpaper

This type of decoration is also actively used before sticking liquid wallpaper. This is simply necessary in order to increase the adhesion of the surface of the walls. Some types of primers are more dense, however, they also allow you to efficiently and effectively smooth the surface of the walls.
