The life of household wallpapers is generally around 5-8 years. They all say that the wallpaper is divided into three parts. If the cloth is improperly laid, the wallpaper is prone to moisture and mildew, and the air bubbles are curled. Then how to cut the wallpaper to extend the life of the wallpaper. What?
First, preparation before construction:
Temperature and humidity: the temperature is required to be between 15 °C and 25 °C, and the humidity is below 85% to avoid construction during the rainy season or weather fusion;
Remove the wall skin: only the water-resistant putty and latex paint wall (different base film material) can be used to lay the wallpaper. Other wood, plaster layer or powdered putty layer, aging latex layer need to be shoveled and then re-constructed according to concrete – plastering Layer / gypsum board / wood products – anti-crack bandage or patch – putty layer sequence to re-do the wall base;
Powdered putty wall can’t be wallpapered
Shovel the wall coating layer to the plastering layer
Clean the wall: the wall surface must be flat (the error should not be more than 2mm), firm, dry, no scale, the wall moisture before construction is less than 6%, the PH value is less than 9, wipe the dust of the wall with a slightly damp cloth;
Measuring wall flatness by ruler
Acceptance materials: Check whether the wallpaper is flawed, and whether the color number and batch number of the wallpaper are consistent. Glue is best to buy natural plant glue, especially for children’s room, it is best to use potato glue, glutinous rice glue, and some wallpaper brands will provide special environmental protection glue; latex paint wall needs to use wall base treasure instead of general base film, base film if and glue The matching effect is better;
Clean and tidy: It is best to clean the construction site before laying the wallpaper, and do not have other types of work to avoid dust pollution, resulting in poor wallpaper, curling and so on.
Second, the construction process
Modification base film: The base film is a professional anti-alkali, moisture-proof and mildew-proof wall treatment material, which can effectively prevent moisture and alkaline substances from externalizing on the construction base surface, thereby protecting the wallpaper. Pour the base film into the basin, add appropriate water according to the ratio of the product description, and stir evenly to the appropriate concentration;

Brushing the base film: the base film is uniformly and completely applied to the base layer of the wall with a roller (large area) and a brush (small area), 1-2 times, and then naturally dried for 24 hours;
Measuring the scribe line: Starting from one end of the wall, use a hammer to find the first vertical reference line and mark it at a certain distance. Accurately measure the height from the top of the wall to the ground;
Vertical line mark
Cutting and parquet: cutting wallpaper, need to be mosaic, need to reserve 5cm for splicing, cut wallpaper, need to be placed in order, you can first cut 3 rolls of wallpaper test stickers;
Patterned wallpaper needs to be pre-patterned
Modulation glue: according to the product ratio description, add water and stir in portions, until the rice paste, put it for about half an hour, see if it is diluted, add a little rubber powder, and finally use a chopstick to vertically insert into the container, no Immediately, the concentration is OK;
Brushing glue: Roll the glue on the back of the wallpaper, fully uniform, brush the feet on both sides, wait a little 5 minutes to soften the wallpaper;
Paper wallpaper: Pull the glued wallpaper apart, stick it from the side of the whole wall, align the vertical line paper from the top to the bottom and use the squeegee to press the wallpaper from top to bottom (pure paper wallpaper, foaming) If the wallpaper or surface has concave and convex shape, use a sponge instead of a scraper), squeeze out the bubbles, scrape off the excess glue and dry it with a damp cloth in time. When attaching the second wallpaper, first fix the high position, then focus on the side of the first sheet. Edge alignment
Cut the bottom of the excess wallpaper
Door and window socket: The position of the switch socket should be laid and then reserved. If the socket switch has been installed, two diagonal lines can be cut from the center point, and four small triangles will appear. Then use the scraper to press around the switch socket. , use the wallpaper knife to cut off the excess wallpaper;
Wallpaper trimming: cut off the excess wallpaper with a utility knife;
Treatment of yin and yang angles: There should be no seams in the male corners, and the yin and yang corners should be smoothed with rollers.
Third, after the completion of construction
Material recycling: Do not throw away the extra wallpaper, keep it spare, so that it can be repaired in the future;
Finished product protection: After the paper is pasted, the doors and windows should be closed for 2-3 days, so that the wallpaper is naturally dry (do not open the heating and air conditioning equipment, so as to avoid the wallpaper from violent shrinkage and cause seaming).
