The application of wallpaper requires above all the precision, the method and a good preparation of the support. But it's one of the most economical and fastest ways to redecorate an interior.
The appellation wallpaper is reserved for a strip of paper (le) more or less thick, smooth or grained, on which was printed (originally "painted") a decor, plain or patterned.
Depending on the presence or not, the size and the distribution of the reasons, the paper will be or not to connections (the grounds then extend from one to the other). From this basic product have been declined other coatings, with paper support, the most common of which is vinyl paper, protected on the surface by a thin transparent PVC plastic layer. This evolution allowed the installation of wallpaper in wet rooms (bathroom and kitchen). In addition, the wallpaper may be leachable. It is then cleanable with more or less vigor with the sponge or the brush...
Various types of wallpaper
Many soft wall coverings are nowadays similar to wallpaper, especially the non-woven, whose particularity is a laying by gluing the wall and not the back of the coating. There is also peelable paper (indicated by a specific pictogram on the label), which peels off easily leaving a thin film of paper on the wall, on which you can line directly. It dispenses with the tedious operation of taking off the old paper. The stripable paper, he, tear easily in totality. Wallpaper is not a cache-misère! If the wall is in bad condition, it is imperative to prepare it. This consists of filling holes and cracks, removing bumps and irregularities of the support, especially when it is coated; because everything is seen under this type of coating, the small thickness of which does not manage to erase the defects of the wall.
Rolls of wallpaper: the good calculation
The wallpaper rolls are traditionally 10.05 m long and 0.53 m wide. To calculate the quantity needed, the number of strips must first be determined. For that, it is enough to measure the height to be covered (from the top of plinth to the ceiling) by increasing it from 3 to 5 cm for the levelings. If the paper is spliced (as here), add the "splice height", ie the distance between two identical patterns (aligned or offset, overlapping or not). This gives the length of the strips. The perimeter of the room is then measured by counting windows and doors.
All the steps of laying a wallpaper decorated with patterns
Measure the height of the walls, from the plinth to the ceiling (+ 3 to 5 cm for the leveling). Carry this measurement on the back of the wallpaper, draw a perpendicular and cut the le.
Prepare the glue in a paint tray (truck) as specified by the manufacturer. To prevent lump formation, create a quick swirl with a wooden stick.
Glue the back of the strips with the pasting brush. Some glues remain colored as long as they are wet to facilitate the verification of a complete glue.
Fold the paper on itself on each side of the lé so that it becomes easier to impregnate. Glue the next layer; the first remaining on hold.
Introduce the first floor flush with the ceiling, the bottom overflowing slightly on the plinth. Hold it with both hands at the top, its weight will make it unfold. Check the verticality.
Rub the paper with a flat brush, starting from the center to the edge of the edge to make it adhere well and chase the air. Immediately wipe off any excess glue.
Overflow the lé on the housing of the switch (or the plug), practice two horizontal cuts with the chisel and make the vertical cut with the cutter.
At the plinth, mark the angle of cut with the rounded tip of the scissors. Cut off the excess paper and then pick up using the brush.
• At the time of purchase, ensure that all rolls display the same "bath" number (which is actually the same series of manufacture and therefore the same color, so this number is important). This will save you from buying rolls that are not exactly the same color as those already laid.
• Always use an extra roll of wallpaper to cover the top of the doors and the underside of the windows.
