Specific steps:
first step
Remove the wall skin: remove the original paint and other things on the wall surface, fill the cracks on the wall surface with gypsum powder, and stick a bandage after leveling; If it is a sand wall or partition wall, it should be covered with glass fiber cloth or polyester cloth; Some partitions or external walls with poor quality need to be nailed up with plasterboard to ensure that the walls are smooth and stain-free, and then wallpaper is pasted.
Second step
Cut the wallpaper: measure the height of the wall first, and then cut the length of the wallpaper. Check carefully whether the color number and batch number of wallpaper are consistent before construction. You also need to know the type of wallpaper to be constructed. The design paper needs to be aligned and the symmetry of the pattern needs to be considered. Therefore, the cutting length should be increased according to the actual situation, usually 8 to 10 cm long. You can number the wallpaper of good flowers to prevent mistakes when pasting. Plain paper should be constructed on both sides. According to the height of the wall, cut off the length of about 5 to 8 cm to trim it up and down.
Third step
Brush basement membrane and glutinous rice glue: The quality of basement membrane and glutinous rice glue will directly affect the overall effect and service life of wallpaper, so you need to buy genuine brand basement membrane and glutinous rice glue. The main function of basement membrane is to protect the wall surface, prevent moisture and alkaline substances from permeating the wall surface, and play the role of moisture-proof, mildew-proof and alkali-proof. Brush the basement membrane on the wall, first brush the corners and corners, and then brush the wall in a large area with a roller. From bottom to top, it can not only prevent the basement membrane from falling to the ground and cause pollution and waste, but also ensure the smoothness of the basement membrane on the wall. Brush evenly and thoroughly to ensure the construction quality. After the basement membrane is dried for one hour, the adjusted glutinous rice glue (glutinous rice glue) concentration will be judged by whether a chopstick can stand in the glue. ) The method of painting the wall is the same as that of painting the basement membrane. Note that not all wallpaper is painted in glutinous rice glue, but pvc is painted in glutinous rice glue. You'd better put a layer of newspaper on the wall before painting.
Fourth step
Wallpaper pasting: generally, the first wallpaper is pasted from top to bottom at the door or in the internal corner. When the first piece of paper is on the wall, it should be perpendicular to the vertical line, and try to keep consistent with the angle of the door and window. Scrape the wallpaper gently from top to bottom and from inside to outside with a scraper to squeeze out bubbles and excess glue, so that the wallpaper is flat and close to the wall. If there is a power switch or socket on the wall, you can turn off the main power supply first, remove the protective cover of the socket, then cover all the power supplies and sockets with wallpaper, cut two diagonal lines from the center of gravity, and four small triangles will be displayed, and then use the art knife to remove the redundant wallpaper around. Scrape the edges with a scraper to prevent them from becoming warped.
Step five
Trimming and cleaning: cut off the redundant wallpaper at the upper and lower ends with sharp edges to avoid burrs. Wipe the glue remaining on the surface of the wallpaper thoroughly with a sponge to avoid yellowing of the wallpaper. During the construction of pure paper wallpaper, it is not allowed to scrape the paper glue hard to avoid polluting the wallpaper surface. After the wallpaper is dried, if bubbles are found on the surface, puncture it with a needle and scrape it flat. If the bubble area is large, it means that the glue is uneven. You can use a syringe to inject glue into it and scrape it flat.
Step 6
Dry wallpaper in the shade: after the paper is pasted, close the doors and windows for 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. If it is rainy season, open the window for 5 hours during the day after 3 days, and then close the window until it is completely dry in the shade. Sticking wallpaper is a very professional technical job. It is best to ask a professional master to post it, and the effect will be better. The after-sales service in America is good, you can have a look.
