First, excessive moisture in the wall after the construction of the base film. The wall of the water content is relatively high. There will be water penetration, the water that penetrates at this time will form a lot of capillary-like holes, resulting in the wall Alkali penetrates through the holes to the wall cloth to corrode the wall cloth. 2. During the construction process, the glue overflows. If the construction is improper, the glue overflows. During the scrubbing process, the scrubbing will also cause discoloration of the wall cloth.
Third, the construction method is wrong In the process of applying the wall cloth, the strength of the wall cloth is too large, and it may cause the waterproof layer on the surface of the wall cloth to fall off at the joint.
Cause the wall cloth to change color and white. 4. If the wall surface is not dried yet, stick the wall cloth if the wall is not dry yet. Because the protective film on the wall is not yet fully working, stick the wall cloth. Extruded water and glue will penetrate the wall, so that the wall, wall and base film, wall cloth will form one, resulting in direct contact between the wall cloth and the wall, the base film will lose its function. Excessive wall surface treatment is not good In the case of base film construction, when the brushing is too thin, the base film cannot form a good protective film on the wall, nor can it be isolated from the wall with alkaline chemicals. Infiltration, discoloration of wall coverings becomes very likely. First, the selected adhesives are not qualified. Many of the adhesive products on the market are basically alkaline or weakly acidic. These products will have certain corrosion on wall coverings. A long time can also cause yellowing of the wall cloth and affect the service life
