What is the reason why the wallpaper is moldy?

1, wallpaper glue is too thin and contains a large amount of water, which will penetrate into the wallpaper surface and even become moldy in the future. Consumers should consider the environmental protection performance of wallpaper adhesive when purchasing, and it is best to choose water-based brand adhesive.

2. The wall is not coated with waterproof layer, which causes the wallpaper to be moldy from the inside out. Qualified basement membrane, as the base layer of wallpaper, will not emit irritating smell, can effectively prevent moisture and mildew, and prolong the service life of wallpaper.

3. If the weather is wet, the wallpaper has poor moisture-proof performance and is easy to get moldy. It is best to choose wallpaper with waterproof function. Wallpapers on the market are divided into PVC, pulp, wood pulp, silk and other categories. Due to the different waterproof and moisture-proof properties of different raw materials, the original wallpaper has weaker water absorption than PVC wallpaper.

4. In wallpaper construction, if the temperature difference between indoor and outdoor is too large and the glue dries too slowly, it is easy to cause the wallpaper to tilt and bulge. Over time, moisture and air will stay in the wallpaper for a long time, and it is easy to cause mildew. After just laying the wallpaper, consumers should close the doors and windows of the room to dry in the shade, and then ventilate the whole room after 3 days.

5. There are many wallpaper materials, and the construction techniques and methods are different. Some consumers think they can wallpaper themselves, but in the final analysis, wallpaper pasting is still a technical job. It is recommended to find a professional expert to ensure the effect of climbing the wall. Otherwise, the paste will not be good and beautiful, which will affect the quality of wallpaper. For example, if the joint is not pasted well, the waterproof effect will be poor.
