Lead: Everyone usually needs a lot of decoration materials to decorate a room. Different rooms and different parts use different decoration materials. For example, when decorating the wall, you need wallpaper or wall covering. In recent years, most people like to use wallpaper as a decorative material to decorate walls. Decorating the wall with wallpaper has a unique construction technology, which must be unknown to everyone. The following small series will introduce the construction technology of wallpaper in detail to help you understand!

Wallpaper construction process steps

1, measure the size of the wall first.

2. Eradicate the wall skin: remove the original paint, wallpaper and other objects on the wall. If there are cracks and potholes in the wall, repair these places with gypsum powder and put a bandage on them after leveling; If it is a sand wall and partition wall, it should be covered with glass fiber cloth or polyester cloth; Some partition walls or external walls with poor quality need to be fully nailed with gypsum boards in order to achieve thermal insulation effect.

3. Cut the wallpaper: measure the height from the top of the wall to the skirting line, and then cut the wallpaper. No, the floral wallpaper is cut about 10 cm according to the height of the wall for trimming up and down; The wallpaper with flowers should consider the symmetry of the pattern, and it needs to be more than 10 cm. The flowers should be aligned from top to bottom, and the numbers should be cut after planning so as to be pasted in order. Wet pasting is not recommended for general wallpaper.

4. Brush the basement membrane: brush the basement membrane evenly on the wall with moderate thickness; Scraping putty and polishing. Carry out two batches of wall scraping putty. After the putty is dry, use sandpaper to polish off the uneven particles on the wall surface to make the wall surface smooth and flat; Brush the wall (finish) evenly with the basement membrane, not too thick. This can prevent the wall from absorbing the wallpaper glue, so that the wallpaper can be firmly adhered to the wall and the wall is smoother.

5. Glue brushing: In order to ensure the firm pasting, glue should be brushed on the back and wall of the wallpaper, and the glue solution should be evenly brushed. It is not allowed to wrap or pile up to avoid soiling the wallpaper. Brush glue on the wall, the width should be 30 mm wider than the wallpaper. After the back of the wallpaper is glued, fold the glued surface for 5 minutes to prevent the glued surface from drying quickly and being polluted easily.

6. Cut wallpaper: measure the length before cutting. Generally, each roll of standard wallpaper is 10 meter long and 0.52 meter wide, and can be spread 5.2 square meters. The other two specifications are 7 sq/ volume, 16 sq/ volume.

7, pasting: the principle is vertical first and then horizontal, first up and then down, first high and then low. When pasting the first piece of paper, find the reference line in the corner, gently flatten it from top to bottom and from middle to both sides by hand, and then scrape it off with a scraper to make the wallpaper stick on the wall. When pasting the second wallpaper, it will overlap the first paper by 20 mm, cut off the overlapping part with wallpaper knife, and scrape off the rest with a scraper. It should be noted that the glue extruded from the wallpaper should be wiped with a wet towel in time to avoid yellowing of the wallpaper over time.

8. When pasting wallpaper: use a roller to evenly spread wallpaper glue on the wallpaper, and the wallpaper will be thicker after a period of time. When you start pasting wallpaper, for the seam, squeeze the two sides of two adjacent wallpapers together to make them match, and then press the seam with a scraper to clean up the extruded glue. After pasting the wallpaper, flatten the pasted wallpaper from top to bottom with a scraper.

Matters needing attention in wallpaper construction

Check carefully whether the color number and batch number of wallpaper are consistent before construction. Also know the type of wallpaper to be constructed, color paper should be aligned, and plain paper should be constructed in positive and negative directions.

The quality of glue will directly affect the overall effect and service life of wallpaper, so you need to buy genuine brand glue or wall powder.

Dry pasting, that is, the construction method of directly gluing water on the back of wallpaper, is mainly aimed at pasted wallpaper. Wallpapers with cross cloth and non-woven bottom do not need to be pasted. The concentration of glue is judged by whether a chopstick can stand in the glue. During the construction of pure paper wallpaper, it is not allowed to scrape the paper glue hard to avoid polluting the wallpaper surface. Don't throw away the scattered wallpaper so that it can be repaired in the future. After pasting the wallpaper, close the doors and windows, don't open the window for 24 hours, and let the wallpaper dry slowly. When you need to hang oil paintings or other decorations on the wall, you should draw a "V" shape on the nail wallpaper for later repair. After the paper is pasted, close the doors and windows for 2-3 days and let the wallpaper dry naturally. Remember not to turn on air conditioning equipment such as heating, lest the wallpaper shrink sharply and crack. In wet season, doors and windows should be opened during the day to prevent the invasion of moisture. Paper has a certain scrub resistance. If it is stained, it can be gently wiped with soap or other cleaning agents. Wallpapers with concave and convex patterns can be cleaned with a vacuum cleaner every 2-3 months. You just need to clean it up with a chicken feather list on weekdays. Don't hit or rub the wall with hard objects such as chair backs and table edges, so as not to damage the wall. If minor surface damage is found, it can be remedied with paint or paint of similar color. In this way, the bedroom decorated with wallpaper can still keep beautiful and tidy after several years.
