Features of choice
The wallpaper is a roll ofdifferent materials. The standard width of the canvas is 53 and 106 cm, length - 10 m. Their main purpose is to provide decorative decoration of the walls. Additional functions of some types include sound absorption and increased thermal insulation. The state standard distinguishes three classes of wallpaper:
Types of wallpaper. The wallpaper is divided into smooth and relief by type; in appearance - embossed, profile, velor, metallized, from untreated paper cloth, decorated with natural substance and wallpaper. Embossed wallpaper is embossed painted, with a report and embossed two-layer. Paper variants that are made from one or two layers of paper are quite common. They have high air permeability. The main disadvantages are low water resistance and accumulation of unpleasant odors. Increasing water resistance is achieved using paper-based wallpaper, such as duplex (two-layer), when the second layer is made of a moisture-resistant material. Vinyl options are a cloth with a protective polymer coating. They can have a paper or non-woven base. Such material has sufficient strength and moisture resistance, which allows them to be washed with water. Wallpaper based on non-woven fabric is made of a material resembling paper, in the form of a mixture of natural and polymer fibers. Recently, a wide spread is found wallpaper for painting. Such instances are most often performed on a paper basis. However, wallpaper with a glass-cloth base is also used. 
Wallpaper for painting can be repainted severaltime. They are white and are designed for latex or water-based paint. Textile wallpaper on a fabric basis looks very beautiful. In addition, on sale you can find special types: wallpaper on a natural basis (cork, bamboo, etc.); metallized (with a metal layer or with the effect of metal); leather; Wall-papers; liquid wallpaper. By the form of the picture wallpaper is divided into primed, background and embossed. In primed wallpaper, the pattern is superimposed on the previously painted paper. The background assumes only the coloring without a pattern. Embossed have a relief volumetric pattern. Back to contents</a>
Preparing the adhesive for wallpaper
Correctly paste wallpaper on the wall allowsstandard adhesive in the form of a dry mixture. This mixture is based on modified starch. The most common form of this synthetic starch is carboxymethyl cellulose (CMC glue). The increase in adhesion to the wall coating is achieved by the addition of a methylcellulose additive. To combat the formation of fungi and mold in the adhesive for wallpaper, bactericidal and antifungal formulations are introduced. 
Scheme of applying glue to wallpaper. The glue in the form of dry powder is sold in packing or by weight. The powder is diluted in water, in the concentration specified in the instructions for glue. Usually one bundle of glue is diluted in 4-5 liters of water, and it is enough to paste 6-7 standard rolls of wallpaper with a width of 53 cm. Water is poured into the container, and with mixing, an adhesive powder is introduced. The adhesive solution is aged for 15-20 minutes, after which it is thoroughly mixed to a homogeneous mass. If there are no lumps in the solution, the glue is ready for use. Back to contents</a>
Preparing the wall for self-gluing
First of all, previously pasted wallpapers orthe other is not a continuous covering. This is done manually or with a spatula. It is possible to pre-soak the poorly retarded layers for 10-15 minutes. When working with a spatula, use caution and do not damage the plaster on the wall. If the plaster on the wall is still damaged, then the places of dents and cuts should be plastered and wiped. The wall, designed to glue the wallpaper, should be primed over the plaster. If this is not done, then there is a danger of dust, which will lead to poor adhesive adhesion. It is best to apply a thin layer of a primer mix to such a wall. You can simply cover the entire surface of the wall with PVA glue, diluted in water. As a result, the walls should be smooth and smooth. In addition, the wall must be dry. Back to contents</a>
Marking and cutting
Scheme of calculating the area of the room for gluing wallpaper. Before you paste wallpaper, you must mark the upper border of their location (if the wallpaper is not glued to the ceiling). For this purpose, the necessary distance from the ceiling is measured, and marks are made on the corners. Then, using a colored construction cord, a straight line on the wall between the marks is repulsed. This line is drawn around the perimeter of the room. It is recommended to mark vertical lines on walls with a step of about 1 m, which will allow to control the verticality of the wallpaper stripes. The lines are drawn using a plumb line. The number of wallpaper strips required per wall is calculated. The first strip is cut off, and on it the pattern on the following strip is made. The pattern on the adjacent stripes should coincide, so the second strip is cut taking into account the figure (when wallpaper is aligned, wallpaper waste may be removed). Thus, all the strips for gluing onto one wall are cut and cut off. Back to contents</a>
Glue wallpaper on plaster
Before gluing, it is necessary to close the windows in order to eliminate drafts.
Figure 1. The order of gluing wallpaper on the wall. When gluing wallpaper on the walls, switches and sockets come in. In this case, it is necessary to de-energize them and remove the cover from them by unscrewing the screws. (Fig. 1). After gluing the strip in place of the electric point, a circle is cut in the wallpaper, with a diameter smaller than the removed cover. After fixing it to its place the boundary of the circle should be under the cover. Back to contents</a>
Glue the wallpaper in the corners
The question is how to glue the wallpaper correctly in the corner,It occurs if the next wall has also a window located close to the corner. In this case, the strip is placed to the back of the first glued strip and wound on the next wall. A part of the strip located on the first wall is glued. Then the section in the strip, corresponding to the position and size of the window sill, is cut out. The upper part of the strip is adhered to the second wall. The lower part of the strip is inserted carefully for the battery and is glued. 
Figure 2. Step-by-step process of gluing wallpaper on the wall. Excess strip of wallpaper, falling on the windowsill, cut with a knife. Smoothing the strip in uncomfortable places is done with a brush or a rag. A strip of wallpaper is cut along the border of the window opening. The question is how to glue the wallpaper over the window, the door and behind the battery, is solved the same way as for the wall surface. The required length of the strip is cut off and pasted to the adjacent strip. Matching the picture is mandatory. The extra part of the strip is cut with a knife along the ruler, applied to the corresponding boundary of the opening (horizontal or vertical). Smoothening of the wallpaper behind the battery is carried out with the help of a rag, accurate movements of the hand. Back to contents</a>
Additional recommendations
A few more recommendations should be considered,helping in the work. Glue wallpaper better together, which will allow one to glue the wallpaper at the top (near the ceiling), controlling the restrictive line, and the other to work below, controlling the vertical. When applying glue, the strip should be placed on a horizontal surface (table or floor), while the strips can be folded in half without bending them. After applying the glue on the wallpaper, it is necessary to allow the adhesive to impregnate the strip for up to 10 minutes. (Figure 2). When using non-woven wallpaper, glue can only be applied to the wall. Glue strips follows, moving from window to door. If the glue in large quantities hit the roll or wallpaper surface, then it should be removed immediately. Roller or brush, designed to smooth the wallpaper, should be constantly cleaned of the glue that gets on them when processing the edges of the strips. Back to contents</a>
