It is available in construction stores and marketsmany finishing materials. They differ in structure, application method, and there is no need to talk about the abundance of colors. Therefore, the consumer finds himself in a difficult situation, since the choice is very large.
Depending on what material they are made ofliquid wallpaper, the method of preparing the walls is selected. But among such a variety of offers, liquid wallpaper stands out. This is a decorative plaster, which has its own application features. But before applying liquid wallpaper to the wall, it is necessary to carry out preparatory work. The main thing is to decide what material they are made of. Further activities and the preparation of the walls for liquid wallpaper depend on this. It also does not hurt to prepare tools for preliminary work:
- spatulas;
- perforator;
- brushes;
- roller;
- empty containers and others.
Features of using liquid wallpaper
Scheme for checking the evenness of a wall.Liquid wallpaper can be applied to walls made of any building materials. The only condition that must be met is to minimize the curvature of the surface. Therefore, if you are using it as a room finish, you need to check how even the walls in the room are and perform leveling work if necessary. But if the wall defects are minor, then by using liquid wallpaper it is possible to hide these flaws. The main thing is to choose the right color. However, if you decide to use white liquid wallpaper, then it is better to paint the walls with paint, at least in 1 layer. This will help to avoid the appearance of various stains that can form when the glue in the decorative plaster interacts with the wall. Most often, the basis for white for further application of liquid wallpaper is water-based paint, nitro enamel will also work. However, water-based paint is preferable, since it is then easier to erase if you need to radically change the room's finish after removing the layer of liquid wallpaper during subsequent repair work.

Concrete (plastered) walls
Concrete walls are leveled with a specialputty, which is based on a gypsum mixture. Such building materials for construction and rough finishing are the most common. Such walls have 1 feature - they are able to absorb a large amount of moisture. Therefore, applying water-based paint to their surface will not lead to anything, even if there are several such layers. This will not bring the ideal white color of the base for applying decorative plaster. But the way out of this situation will be the use of putties, which are based on gypsum mixtures. It is such putties that not only level the walls, but also fill the pores of the concrete, which prevents moisture penetration. After drying the applied layer of putty, which should also be leveled, you can apply a primer. Moreover, it is advisable not to limit yourself to 1 layer, 2-3 layers will be preferable. In this case, it is necessary to allow the treated area to completely absorb the solution. Only after complete absorption can you paint with water-based paint to give the wall an ideal whiteness.
Wooden walls must be primed at least2 times. An alternative to the primer can be water-based paint for external facade works, to which PVA glue is added. The proportion for such a solution is 2 parts paint and 1 part PVA, while mixing must be done thoroughly enough. But the putty layer when using such a solution should be at least 0.5 cm so that the concrete does not show through it after final drying. It is necessary to paint with such a composition at least 3 times, since the first layer will only be an initial impregnation and will not be able to provide proper preparation of the wall for decorating with plaster. If concrete walls are subject to significant unevenness and defects, then they must be repaired using plaster. If the existing plaster does not hold firmly, peels and crumbles, then such places on the wall are best cleaned to the base, which does not crumble and plastered again. If this is not done, then when applying liquid wallpaper, not only their deformation is possible, but it will also be impossible to perform this amount of work. However, if peeling is not of a widespread catastrophic nature, then the use of special bonding primers will help to avoid problems with decorative plastering. Return to contents</a>
Houses of indeterminate materials
Walls in old houses before coveringliquid wallpaper, you must first cover it with impregnation. An example of such houses can be old houses built in the mid-20th century. Then, the most unexpected materials were used for housing construction, sometimes different in density and moisture absorption characteristics. Therefore, at the 1st stage of preparing the wall for applying liquid wallpaper, it is necessary to cover it with a layer of impregnation, and at the 2nd stage, apply several layers of primer, at least 2. Then you can start painting with water-based paint to get a white color. An alternative to primer can be oil or acrylic paints. To prevent streaks and stains, protective layers should be applied several times. This is a must for walls of this quality. Return to contents</a>
Liquid wallpaper: preparation of walls from plasterboard
The plasterboard wall needs to be treatedputty the entire surface. After fixing the plasterboard sheets according to the technology, putty the surface. However, it is absolutely impossible to limit yourself to applying putty only to the joints when applying decorative plaster. This is due to the fact that the putty itself is a material that absorbs moisture well, and even the application of special water-repellent compounds does not guarantee the absence of manifestation of seams when finishing with decorative plaster. Therefore, it is extremely important to putty the entire surface of the plasterboard wall. And then apply water-based paint. To further improve the moisture-resistant characteristics of the putty, PVA glue is added to the water-based paint at a ratio of 3:1 (paint to PVA). The use of galvanized screws at the stage of installing plasterboard sheets will avoid the appearance of rust when applying liquid wallpaper. However, if the installation was still carried out with ordinary screws, then they need to be sunk a little deeper, and the heads carefully filled with putty and additionally covered with oil paint.

Walls made of wood materials and liquid wallpaper
Before preparing the wall for liquid wallpaperIt is necessary to make sure that the wooden surface (plywood sheet, chipboard sheet) is securely fastened, otherwise deformations are possible when exposed to moisture. If the wooden covering is thin, then the probability of its rapid deformation is higher than with a thicker sheet. Therefore, it should be prepared more carefully. Such a surface should be primed at least 2 times, and then painted with water-based paint, also 2 times. Then the whiteness effect will be achieved. Liquid wallpaper is a very beautiful and textured finishing material. This decorative plaster is produced in various colors, and the addition of fillers allows you to achieve various visual effects. The peculiarity of this material is that it must be prepared so much as to cover the entire wall at once, that is, it is diluted in full. Therefore, the preparation of the walls for liquid wallpaper should be done entirely. The preparation itself is not a complicated process, but it is necessary, and you should never skip it. Only then will they sparkle in all their glory and last a long time.</ ul>
