The reasons for the discoloration of wall cloths mainly include the following six aspects.
First, when the wall cloth is pasted, no moisture protection work is done and the moisture content of the wall is too high.
In some areas, there is more rain in summer and the wall tends to return to the tide. In particular, some friends in the south did not use the base film when pasting wallpaper, and did not do a good job of wall protection to adhere to the wall cloth, resulting in a high moisture content in the wall. It is easy to cause wall cloth to be damp and moldy.
