Features of the primer
This composition, which is also called prime, performs the task of an auxiliary material. Thanks to him, you can successfully complete the wall cladding, therefore, it is in demand before the wallpapering procedure. Homogeneous suspension of different density is produced without unpleasant and pungent odors. It may have no color, be white, or have a different shade.
Once applied to the coating, the mixture dries and a colorless film is created. As for the set of ingredients, the material contains adhesives, organic resins, and other additives that are prepared on different bases.
Various additives and fillers are often mixed into the solution, which improve the performance of the product. The primer can be produced not only in liquid form, often a dry powder is offered on the market, which must be diluted with a certain amount of water.
All data and characteristics are indicated on the packaging, the same applies to the instructions for use, solution consumption, drying time, and shelf life.
There are a number of properties that any primer should have. The main characteristic is the depth of penetration of the composition into the surface to be processed. The composition should increase the adhesion of the wallpaper during gluing. Antiseptic qualities are of great importance, since the surface must be protected and the material must be resistant to the appearance of fungus, mold and other representatives of microflora. It is important to carefully examine the absorption and drying period, it should be fast.
Before buying, you need to decide on the choice of a type of primer, and also take into account the characteristics of the premises and the conditions of its operation. Find out in advance what material the wall is made of, since there are different compositions for plaster surfaces, and others for wood and drywall. The efficiency of processing depends on this. It is recommended to consult with a qualified specialist, find out his opinion, and take advice.
The composition is selected for a certain type of wallpaper, since they are traditional and liquid, and for preparatory work it is necessary to choose the appropriate version of the finishing material. It is important to examine the density of the cladding.
Scope of application
Priming is an important point that will determine how effective the result of interior decoration with wallpaper will be. The primer solution allows you to achieve a perfect wall surface. This mixture, covering various defects, is intended for leveling the coating. It can have a coloring pigment, therefore, the composition is often used as the main material for finishing ceilings or walls.
The primer penetrates deeply into the structure of the surface structure, therefore fills cracks and micropores, can hold together dust residues, so the cladding will look perfect, and the wallpaper will be glued at the highest level without problems and complications. With the help of the mixture, the material on the walls is disinfected, which makes it possible to increase the resistance to factors that can be biologically aggressive.
Using a primer, you can achieve good adhesion, which means that due to the composition, the wallpaper glue adheres perfectly to the coating and the wallpaper itself. Thus, the canvases will not flake off either at the joints or in the corners, which is no less important.
There are the following types of primers:
Acrylic primers are made with the addition of polymer binders. For internal surfaces, this option is best suited. The material does not have a pungent odor, dries quickly, and can also be applied before gluing various types of canvases. Using the mixture, you can greatly facilitate your finishing work. The hygroscopicity of the surface will be improved, the service life of the facing material is extended, the surface is protected from damage, and the consumption of the adhesive is minimized
Latex is a natural component that is extracted from rubber juice. A primer on such a basis in a synthetic form is widely used during repair work. It is characterized by high strength, resistance to compression and stretching, elasticity and waterproofness. The primer is a clear liquid which, when dry, provides excellent adhesion
Alkyd primers suitable for wood, as they prevent it from swelling. The composition is resistant to mold and mildew, is moisture resistant and is offered at a favorable price. The mixture does not penetrate deeply into the surface, therefore it is suitable for preparatory work
For interior and exterior decoration, you can choose universal primer, which extends the life of the decorative coating. It copes with different types of surfaces and is applied in two layers, but at the same time the consumption is minimal

And for rooms with high humidity, it is worth choosing an antiseptic material, where there are substances that will prevent the development of fungus. The composition has a high indicator of water resistance. With this primer, adhesion is guaranteed.
In the bathroom, where you also want to use wallpaper on the walls, you need to apply three layers of the mixture. If it is necessary to treat a metal surface, an anti-corrosion compound will be required.
