In construction shops and marketsmany finishing materials. They are different in structure, method of application, but there is no need to talk about the abundance of color gamut. Therefore, the consumer finds himself in a quandary, since the choice is very large. 
Depending on what material is made ofliquid wallpaper, the method of wall preparation is chosen. But among such a variety of proposals stand alone liquid wallpaper. It is decorative plaster, which has its own application features. But before you apply liquid wallpaper on the wall, you must perform the preparatory work. The main thing is to decide what material they are made of. On this depends on the further activities and the preparation of walls for liquid wallpaper. Also, for preliminary work, it is also possible to prepare tools:
- spatulas;
- perforator;
- brushes;
- roller;
- empty containers and others.
Features of using liquid wallpaper
Scheme for checking the evenness of the wall.Liquid wallpaper can be applied to walls made of any building materials. The only condition that must be met is the minimization of the curvature of the surface. Therefore, if as a decoration of the room, then it is necessary to check how even the walls are in the room, and perform work on their alignment if necessary. But if the defects of the walls are insignificant, then thanks to the use of liquid wallpaper, it is possible to hide these flaws. The main thing is to choose the right color. However, if it is decided 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 interacts in the composition of the decorative plaster and the wall. Most often, the basis of white color for the further application of liquid wallpaper is water-based paint, nitro enamel is also suitable. However, water-based paint is preferable, since it is easier to erase it later if it is necessary to radically change the decoration of the room after removing the layer of liquid wallpaper during subsequent repairs.

Concrete (plastered) walls
Concrete walls are leveled by specialPutty, based on a plaster mixture. Such construction materials for construction and roughing are the most common. These walls have one feature - they are able to absorb a large amount of moisture. Therefore, the application of water-based paint on their surface will lead to nothing, even if there are several such layers. This will not bring an ideal white base color for applying decorative plaster. But the way out of this situation is the use of putty, based on gypsum mixtures. It is these putties not only level the walls, but fill the pores of concrete, which prevents the penetration of moisture. After the applied plaster layer has dried, which must also be leveled, it is possible to apply a primer. And it is desirable not to be limited to 1 layer, 2-3 layers will be preferable. In this case, it is necessary to allow the treated area to soak the solution to the end. Only after the final soaking can be painted with water-based paint to give the wall an ideal whiteness. 
Wooden walls must be primed at least 2time. An alternative to the primer may be a water-based paint for exterior façade work, to which PVA glue is added. The proportion for this solution is 2 parts of the paint and 1 part of PVA, and the mixing should be done carefully enough. But the layer of putty when using such a solution should be at least 0.5 cm, so that the concrete does not show through it after the final drying. This composition should be painted at least 3 times, since the first of the layers will be only the initial impregnation and will not be able to ensure proper preparation of the wall for decorating with plaster. If concrete walls are subject to significant irregularities and defects, they must be repaired using plaster. If the existing plaster does not hold firmly, peels and crumbles, then it is best to clean such places on the wall to the base, which is not strewed and plastered again. If this is not done, then when applying liquid wallpaper, it is possible not only to deform them, but it will not be possible to perform this amount of work. However, if exfoliation does not have a general catastrophic nature, the use of special fastening primers will avoid problems with decorative plastering. Back to contents</a>
Houses of indeterminate materials
Walls in old houses before coveringliquid wallpaper, you must first cover with impregnation. An example of such houses can serve as old houses dating back to the mid-twentieth century. Then for the construction of housing in the course were the most unexpected materials, sometimes heterogeneous in terms of density and characteristics of moisture absorption. Therefore, at the stage of preparation of the wall for the application of liquid wallpaper, it is necessary to cover it with a layer of impregnation, and in the second stage, apply several layers of a primer, at least 2. Next, you can start painting with water-based paint to obtain a white color. Alternatives to the primer may be oil or acrylic paints. To prevent divorces and stains, apply protective layers several times. This is a prerequisite for walls of this quality. Back to contents</a>
Liquid wallpaper: preparation of walls from plasterboard
The plasterboard wall must be treatedputty the entire surface. After fixing the gypsum plasterboards according to the technology, the surface is puttyed. However, it is categorically impossible to restrict the application of putty only to the joints when under 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 seams when finishing with decorative plaster. Therefore, it is extremely important to putty the entire surface of the plasterboard wall. And after that, apply water-based paint. To further increase the moisture-resistant characteristics of the putty, PVA glue is added to the water-based paint at the rate of 3: 1 (paint to PVA). The use of galvanized self-tapping screws at the stage of installation of drywall sheets will avoid the appearance of rust when applying liquid wallpaper. However, if the installation was still carried out with ordinary self-tapping screws, then they need to be drowned a little deeper, and the caps must be carefully 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 wood covering has a small thickness, then the likelihood of its early deformation is higher than with a thicker sheet. Therefore, it must be prepared more thoroughly. 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 available in a variety of colors and the addition of fillers allows for different visual effects. A feature of this material is that it must be prepared so much to cover the entire wall at once, that is, it is bred in full. Therefore, the preparation of walls for liquid wallpaper should be done entirely. The preparation itself is not a difficult process, but necessary, and in no case can you skip it. Only then will they play in all their glory and last a long time. </ ul>
