Many consumers have high expectations for wallpaper decoration, and intend to enjoy the decorative effect of wallpaper once and for all. In fact, there may be many problems after the wallpaper is on the wall, which has a lot to do with the paving technology and the quality of the wallpaper. When there is a problem with the use of the wallpaper, find out the cause in time to solve the problem.
a warped edge
There are two main reasons why wallpapers have a warp:
1. The starting edge caused by the thermal expansion and contraction movement of the wallpaper surface in use;
2. The re-emergence of the base layer causes the paste for bonding to produce a softening edge.
Two bubbling
The blistering of the wallpaper is similar to the reason for the curling. It appears in the middle of a wallpaper because the middle part is not stressed. The main reasons for the start are two aspects:
1. The anti-alkali on the wall causes the putty to be powdered, and the surface of the wallpaper shrinks and is separated from the base layer;
2. When the wall is partially pasted, the glue is unevenly distributed, and it is foamed due to lack of glue.
Three mold
Excessive moisture in the base layer, if not infiltrated or volatilized in time, may cause the wallpaper or the base layer of putty mold to become powdered. The main reasons for the excessive moisture on the wall are:
1. The new wall surface is not completely dry and is treated as a wall surface (including the base film is not dried and the base film is sealed);
2. After the ground is leveled, the wall is damp;
3. When the floor tiles are pasted, the water is too much to make the wall damp.
It is also common to have problems after wallpapering, especially if the wall is not properly handled, it is easy to cause problems after the wallpaper is laid. This time is not necessarily related to the quality of the wallpaper. In addition to choosing high-quality wallpaper, consumers should pay attention to the construction process.
