How much after the primer can I glue the wallpaper?

If you decide to glue wallpaper, you should know - not such a simple thing. First of all, the walls must be carefully prepared, because the quality of the future coating depends on it: its durability, beauty, practicality, ease of care. And of course, it is very important to know how much after the primer you can glue the wallpaper. First of all, such knowledge will help in the proper organization of work, besides, all the work will be performed much better.

Why are walls grounded?

Primer is a special emulsion, which is necessary in order to improve the adhesion of wallpaper and the surface to be treated. Due to a special primer composition, the upper layers of the substrate are impregnated, whereby it becomes more durable and wear-resistant.

Important! Soil is used not only for the treatment of walls, but also for the ceiling, floor, facade of buildings.

In addition, the primer also has additional properties:

• Metal protection against corrosion;
• The absorbing surface of the surface is reduced;
• Under the coating, fungus and mold do not develop;
• Smooth-slippery surfaces receive additional grip.

Features of composition and use

• Primer emulsion consists of natural, synthetic, liquid or solid film-forming materials: drying oil, epoxy or alkyd resins. It is possible to add fillers: chalk or talc.
• To apply a primer to the surface, use a brush, spatula or roller.

Important! Prior to the priming is required to perform preparatory work: the walls are removed paint, worn wallpaper. In some cases, they need to be degreased, for which a solvent is used.

What are the priming compositions?

The answer to the question, after how much after the primer can be glued wallpaper, directly depends on the type of composition and the specific products of a particular manufacturer. On the market of building materials, primers are presented in huge quantities. They have different composition, purpose and duration of drying. They are special and universal.

Due to the designations and properties, the primer is divided into types. The mixture can be as follows:

• Concrete contact. A similar mixture consists of quartz sand, cement, other fillers. The composition is based on an acrylic binder.

Important! It is used to increase the adhesion of a slightly absorbent or smooth surface with plaster, glue or putty.

• Colorless. It is used for processing wooden surfaces. The natural structure of the wood is preserved. After processing, a waterproof film is formed, so that the wood is protected from decay.
• Penetrating universal. With its help, the surface is prepared before laying the tile or painting.

Important! Such a composition is intended to strengthen loose and crumbling bases.

• Film-forming. It is used for problematic surfaces. This coating is intended to strengthen the base, create a film, due to which the supply of moisture is limited.

Important! This coating is suitable for all surfaces, because it dries very quickly.

• Contact. Such a primer helps hard surfaces get better adhesion to solutions.

Is priming so important?

And can not you do without this process, because repair and so takes time, and so it will have to be spent even more? Can I glue wallpaper without a primer? If you take into account only the theory, then quality and smooth wallpapering is possible without preliminary preparation. But! The walls should be smooth, without defects. And this is not found even in new buildings.

Important! Experts argue that without the preliminary priming of the surface, you can not get the expected effect even from expensive and functional wallpapers.

After processing fragile walls they will cease to crumble, there will not be a lot of dust that prevents the wallpaper from fastening well to the wall. Thanks to such actions, wallpaper can last up to ten years.

Important! In the event that the wallpaper is applied to the paint, the primer layer will help to make its color more even. In addition, and wallpaper glue will be used in less quantity, since the surface will not absorb moisture very much.

How long do priming mixtures dry?

• The greatest prevalence among modern mixtures is in acrylics. Usually they dry up in four to eight hours.
• Oily and contact mixtures of time will need more. Wallpaper can be glued only after 24 hours.
• If alkyd resins are based on the soil, it will take ten to twelve hours to dry it.

Important! If the package of the primer mix indicates that it is quick-drying, wait at least six hours.

If you do not take into account the quality of the substrate, the mixture can be divided into those that dry normally, and those that dry for a long time:

• The first group dries in four to six hours.
• Long drying compounds dry for at least twelve hours.

Important! If the primer is applied to the plaster, then further work can be done in two to three hours. But the wallpaper can be glued in six to twelve hours.

Features of the application

Of course, it is important to know after priming the walls when gluing the wallpaper, but you need to be able to apply the primer correctly:

• The material is applied in a thin layer, and the formation of drips and streaks should not be allowed.
• Before work, it is necessary to study the recommendations and instructions.
• If the characteristics of the composition indicate that it has a high level of penetration, its layers are applied in turn.

Important! In this case, the application of the next layer is carried out only after the previous one has dried.

• In the event that the walls are primed with diluted wallpaper paste, the wallpaper can be glued to its final drying.
• During drying, the temperature in the room can not be changed drastically.
• Do not allow drafts to occur.

We learned that it is very important to know how much the primer will dry. Of course, all these works can be done independently. Only be sure to check the recommendations of the specialists and the instructions to the materials before doing this.
