Why are many hotel wallpapers moldy and warped?

Moldy wallpaper is mostly caused by humidity, such as wall seepage, bathroom entrance, dark corner and so on. There is another reason for the humidity in the room back to Nantian (please pay attention to closing the doors and windows).

The edges of wallpaper are mostly opened when the wallpaper is not dry, and floor heating can also lead to large areas of edges. If the wall surface is not polished, the wall surface will be unstable after wallpaper construction, which will also cause the wallpaper to warp.
