Can I choose wallpaper for home decoration in South China?

Due to heavy rainfall and high air relative humidity, mildew is more likely to occur in the southern region than in the northern region, but if the wall surface is well solved, wallpaper can be pasted.

The following points are very important:

1. The wall surface must be dry, which can be detected by an environmental humidity detector, and the standard value cannot exceed 8 (most wallpaper builders have this equipment to identify whether the wall surface is suitable for wallpaper pasting). This can minimize the construction in rainy days and choose the time when the temperature is good.

2. Indoor decoration must be waterproof, both inside and outside the wall, to avoid water seepage in the middle and late period.

3. Prepare moisture-proof solution. When the waterproof wall is finished and the putty powder is approved, it can be used as moisture-proof liquid. Spray the mildew remover on the wall and then brush the basement membrane. The basement membrane is waterproof and alkali-resistant. It is necessary to use basement membrane for wallpaper. It is recommended to use rhombic basement membrane, and the thickness of the coating should prevent moisture from infiltrating from the wall. It is not inconvenient to spray the mildew remover after the basement membrane dries, which is inconvenient in the early stage and difficult to cause problems in the middle and late stages.

4. Choose wallpaper and choose wallpaper with good air permeability. Compared with pure paper wallpaper and PVC wallpaper, non-woven wallpaper has good air permeability.

5. Choose wallpaper glue and construct it properly. When mixing the glue, try to thicken the glue and dilute it as much as possible. It takes about 3-4 hours to make wallpaper glue. In this way, the wallpaper is not easy to grow mildew, nor will it become warped and crack. Because the wallpaper is tilted, cracks appear in many cases because the glue is too thin or too thick. This depends on the level of the construction master.

6. The wallpaper is pasted normally, and the window is closed for 3-5 days to dry the wallpaper. Naturally, in the rainy weather in the south, the surface of wallpaper will grow mold more or less. Therefore, during this period, attention should be paid to ventilation, so that water can volatilize, which can effectively prevent it. However, after the initial solution, the most feared large-scale mildew and edge warping are unlikely to occur frequently.
