Today, almost every store you can find a table in which the number of rolls of wallpaper is correlated with the area of the room and ceiling height, with a table indicates that the calculation is made for a room with one window and one door. For example, a room of 20 m2 with high ceilings 2,4-3,05 m is recommended to buy 14 rolls. Here, however, laid down some surplus.

Calculating the number of wallpaper is actually very simple. Measure the perimeter of the room, subtract from it the width of the doorway and windows, round the result to the greater whole, multiply it by two (the width of wallpaper is usually 53 cm, and glue them back to back) and you get a number of panels of wallpaper, necessary for pasting. Next - a little more complicated. The length of the cloth should be about 10 cm longer than the height ceiling. If the wallpaper does not have a clear picture as shapes, colors, and similar images, they can be safely cut in the cloth of the length of what is needed. This is the most convenient and economical form of wallpaper. Number of panels in a roll, we obtain by dividing the length of the roll (typically 10 m) length of cloth. So we define the required number of rolls of wallpaper. For example, a room of 20 m2 with ceiling 2,75 m, the usual window and door missing 11/12 rolls.

Wallpaper, in which drawing figures are identical, and all banners are identical, cut, put it on each other and aligning the image. Problems are also usually not arise.
The hardest part - preparing wallpaper with displaced pattern. When they cut should closely monitor combining drawing. Evaluate the required number of wallpapers in this case is difficult, since the waste can go a lot of cane pruning, so that they will have to buy a particular stock.
When Wall covering never throw away their labels. Imported wallpaper of a series produced with the same pattern, but often unnoticed in a roll of color difference, which is nevertheless on the wall is evident. The label of each roll is a digital label, which contains all the information about this type of wallpaper, and time series output, as well as the color of the wallpaper. Therefore, buying wallpaper, make sure to check all the rolls on the coincidence of markings. Well, if you accidentally did not have enough wallpaper and you want some time change any section of the wall, the shop is better not to go with the remnants of wallpaper, but with this label, then the color match is guaranteed.

Criterion of quality wallpaper manufactured in Europe is the presence of the symbol RAL - a mark of quality European Union manufacturers of wallpaper, which is extremely hard regulates environmental cleanliness and safety of wallpaper. According to ecological criteria for the EU today wallpaper should not contain such toxic and hazardous to human health, as vinyl chloride, chloral- and fluorocarbons, they should not release hazardous volatile compounds, including aromatic hydrocarbons, and their production should not be used easily evaporating and highly volatile solvents , softeners and plasticizes.

That's why virtually all wallpapers contain formaldehyde in strictly limited quantities, and to stabilize vinyl polymers are not used heavy metals - lead and cadmium. Wallpapers, satisfying the requirements of RAL on ecology, can be used in any room, as in the office and residential, including facilities for children.
