First of all, the high wall can keep the wall dry in the tide.

The wall must be kept dry, and the new cement structure must be kept for 20 to 40 days before wallpaper can be pasted. It is worth noting that attention should be paid not to make irregular construction unsuitable for sand-mixed decoration of wall coatings. Sea sand has a high salt content and is easy to absorb water, so the "flood" is inserted in the back wall.

Second, pay attention to the construction of high-rise wall moistureproof

Generally speaking, wallpaper has various patterns; When placing, we must pay attention to whether there is a big gap between the two backgrounds and whether the mosaic is aligned. In addition, the spread of irrigation will be wet wallpaper, which will shrink after drying, leaving a good extension position. Try not to reduce the opening of the wall to the wind.

Third, pay attention to the moisture-proof maintenance of high-rise walls.

Don't open doors and windows within 24 hours after construction and completion. Excessive ventilation leads to sudden drying and uneven shrinkage of wallpaper, which leads to cracks at joints. After paving for 3 days, pay attention to adjust the ventilation. Open doors and windows during the day to keep ventilation. Be sure to close the doors and windows at night to prevent moisture from entering and affecting the firmness of mortar.

Fourthly, breathable materials should be selected for high-rise walls to prevent moisture.

At present, there are many materials on the market, including non-woven fabrics, wood fibers, PVC, glass fiber substrates, cloth covers and so on. Relatively speaking, PVC wallpaper has the best sealing performance and is easier to download on the wall. It is filled with water vapor, which is easy to form after a long time.

Fifth, there are curls and foams.

If the wallpaper is curly, you can use a special wallpaper eraser to brush the back of the wallpaper, and then scrape it off with a scraper. If there is foam, you can inject glue with a syringe, then gently press it and wipe off the excess glue. You can use glue. When choosing wallpaper glue, we should pay attention to the choice of glue for environmentally friendly wallpaper. Don't choose rubber powder and glue because they contain formaldehyde. Choose a powder without vegetable starch.

I believe that after reading today's article, you don't have to worry about high-rise walls.
