Secrets of preparing walls for wallpapering

The process of preparing the walls is of great importance when pasting them with wallpaper. On an uneven surface, it is unlikely that it will be possible to accurately and correctly paste wallpaper, observing the pattern and combining the joints. To prevent cracks and other defects from appearing on the surface, all stages must be carefully carried out. Preparing walls for wallpapering does not require specific knowledge, you need to be patient and have a desire to get a good result.

Why is it worth preparing?

There are many reasons not to neglect the preparation process, these include the following:

1. The quality of gluing fabrics. On a porous surface, the wallpaper will not adhere well.
2. Irregularities on the walls. The wallpaper is not able to hide the recesses and bumps of the surface; in a certain light, all the flaws will come out.
3. The presence of dampness and the appearance of fungus. If there are cracks on the walls in contact with the street, then cold air will enter the room through them, as a result of which moisture will appear, which favors the formation of fungus.
4. Improving the adhesive properties, that is, the adhesion of the material to the wall.

The preparation of the walls for wallpaper is carried out carefully, so the coating will last longer.

Dismantling

Preparing the walls for wallpapering begins with the release of the old finish. Often this procedure is difficult, but it is very important, otherwise the subsequent work may be useless.

1. Paper wallpapers must be thoroughly moistened with soapy water, so they will be easier to fall behind.
2. Scratches and cuts should be applied to dense and washable wallpapers so that the solution penetrates inside. Then they are removed with a metal spatula. If necessary, repeat the soaking procedure.
3. Vinyl wallpaper is removed according to a different scheme, for this, horizontal cuts are made on them, and then the top layer is removed. The bottom layer can be used as a base.

Procedure for preparing painted walls

It is no secret that wallpaper on a smooth and painted surface will not adhere well. Therefore, paint from such a wall must first clean off.

1. As an option, serifs are applied to such a surface, sanded and coated with a primer. But with this treatment, the wallpaper will not hold tight.
2. You can use a building hair dryer. To do this, heat the painted area and remove the softened paint with a spatula. With this method, chemical compounds evaporate from the surface of the paint, so it is necessary to ensure a constant supply of fresh air so as not to get poisoned.
3. Also use a grinder with an iron brush. This method is very dusty, therefore, requires certain protective measures.
4. Washing is one of the most effective cleaning methods.

All work must be carried out in compliance with safety rules: before work, wear gloves, a respirator and goggles for protection. The walls under the wallpaper are leveled after the paint is removed from the surface.

Procedure for preparing walls in new buildings

Some new buildings for rent without a rough finish, and then before wallpapering it is necessary to carry out wall plastering.

• At the initial stage, plaster is applied to the walls in the form of a spray with a thickness of 3 ─ 9 mm. This layer will affect the quality of the final layer of plaster.
• At the next stage, we apply several layers of primer with a thickness of 0.5 cm.
• At the third stage, a coating or a final layer of plaster of 2 ─ 4 mm is applied to the surface. The purpose of this stage is to create a thin layer of a film on the surface of the soil, which is then overwritten.
• At the last stage of the wall under the wallpaper putty and polished with sandpaper.

Eliminate imperfections on the surface

Preparing walls for wallpaper requires leveling the surface.Concrete surfaces, as a rule, have irregularities and defects. Competent preparation of walls for wallpaper provides better adhesion. The spackling process will smooth the surface as much as possible. Before work, it is necessary to prepare spatulas of various sizes, putty, a container of water. The floor is covered with foil. The surface is pre-primed for better adhesion of materials. Water is added to the dry finished mixture, thoroughly stirred until uniform. Finishing work is carried out with a spatula. A layer of putty is applied in a small layer, carefully filling all the irregularities. During operation, the spatula is constantly dipped in a container of water so that the remains of the mixture do not stick to it. Drying time depends on the thickness of the layer.

Grinding procedure

After the puttying process, proceed to surface grinding sandpaper or special sanding mesh. This work is quite dusty, so it is important to use personal protective equipment. Grinding begins to be carried out in separate areas in the direction from one corner to another.

Primer for wallpaper

At the next stage apply a primer. There are the following types of primers:

• acrylic;
• mineral;
• alkyd;
• with deep penetration;
• with pigments.

The choice of primer composition depends on the condition of the walls. The following tools are required for applying the primer: wide roller, brush or spray. In hardware stores you can buy both dry and diluted primer.

The finished solution is applied to the surface in one or two layers, depending on the condition of the surface. To do this, a special roller is moistened in a primer solution and applied to the wall; a brush is used for hard-to-reach places. The layers should dry properly, only after that they begin to stick the wallpaper on the wall.

Preparing the walls for wallpapering is a laborious, responsible and very painstaking task, but with the help of useful tips, the process will go faster. The whole procedure is able to perform a person without special education.
