Acquisition of wallpaper and glue
First of all, the number of wallpapers is calculated,which you need to work. Let's do it on an example. Imagine that your room has dimensions of 5 × 4 m with a ceiling height of 3 m. The selected rolls have a width of 500 mm (0.5 m), and their length will be 10 m (standard dimensions). First, the perimeter of the room is determined: 5 × 4 = 20. The number of webs is calculated by dividing the perimeter by the width of the roll: 20: 0.5 = 40 pcs. The width of the roll can be 1 m. Then the number of necessary cloths will be 2 times less. 
The proportions of the glue for different wallpapers. The height is taken into account with the additional centimeters for alignment. For example, 3.1 m is obtained. To determine the total length, the number of canvases is multiplied by their height: 40 × 3.1 = 124 m. Based on the length of the roll at 10 m, the length of the wallpaper is divided by 10, which will be 12.4 . Rounding out this figure, naturally, in the big direction, it turns out that for our example you need 13 rolls. Calculations can be made with a deduction of the space that is accounted for by windows and doors. However, such accurate calculations are not needed, because the superfluous wallpaper will not be, which is connected with the process of fitting the picture or with a possible marriage. The choice of adhesive is based on the type of materials selected. In the consumer market at the moment there are two main types: universal, suitable for any type of wallpaper, and special.

Table calculating the number of wallpapers. Bringing the surface of the walls to the ideal state before gluing the wallpaper positively affects the result. The entire stage of preparation depends on their initial condition. In new buildings, the walls are pre-sprayed, the thickness of which should not exceed 9 mm. Then a primer with a thickness of about 6 mm is made. Sometimes the application of soil occurs in several stages. Next, apply a thin layer of plaster (2-3 mm), called the covering. It creates a thin film, convenient for the subsequent cleaning of the wallpaper. At the end, it is necessary to level the walls with sandpaper. If the walls already have old wallpaper, they should be removed. Many glue new canvases over the existing ones. After carrying out such a procedure, the first layer can not stand and fall off. How to glue the wallpaper in this case? Do not take risks, arm yourself with a spatula and remove the old coating.

Such a method is harmful to health, because when the paint is heated, harmful chemical elements are released. You can also remove it using a grinder.

Wallpaper gluing
Before gluing, a roll of wallpaper unfoldsand placed on the floor in such a way that the front side looks down. With the help of centimeter tape, the length of the necessary cloth is noted, to which it is necessary to add 100 mm for the possibility of adjustment on the wall. 
Before you start, you need to readrecommendations from the manufacturer, indicated on the roll packaging, tk. On the reverse side of some wallpaper, you also need to apply glue. In the event that the pattern does not require adjustment, you can immediately cut several strips. If you need docking, then the wallpaper is cut so that the image on them matches. In many species, the tolerance level is already specified. With the help of a level or a cord, vertical lines are drawn. To start their marking is better from the window. Glue the wallpaper in the corner so that they lie on the other wall, so in this area it should be noted that the width is slightly less than 0.5 m (less than the full width of the roll). This will allow you to correct the layout of the canvas in case of "buried" corners. Depending on the type of wallpaper, the adhesive can be applied directly to the web, which is then folded in half so that the impregnated side is inside. In this state they are maintained for some time according to the instructions (thin - about 5 minutes, thicker - about 10). It is important to apply glue evenly, as, when soaked, the wallpaper is stretched. If the adhesive is not equally distributed across the strip, bubbles may form. When gluing thick wallpaper, glue is also applied to the wall. For materials on a non-woven base, it is sufficient to lubricate only the wall. 
The scheme of wallpaper gluing. The first glued strip is aligned along the intended line. Glue the wallpaper further follows by butt or overlap, depending on the pattern. The process is carried out from the window deep into the room, so that the distribution becomes correct, and the shadow will not interfere. The glued wallpapers are leveled using a piece of cloth or a roller. Smooth them from the middle to the edges. While the canvas did not dry out, it is cut off with a knife, holding a metal spatula for the ceiling, floor or skirting. If it is necessary to observe the indentation, it is worthwhile to draw a straight line across the room and glue it already from it. Do not forget to check the edges, they may fall behind.
