During interior decoration, there will be a serious problem when sticking wall decorative film. There is no problem when it is just done, but once it is used for a period of time, there will be problems such as falling off and bulging. So what is the reason? Let's analyze it together. Reason one:
The base layer is not cleaned up. If the surface of the wood grain melamine paper base layer is not a smooth and smooth surface, but there are stains or impurities on it, it may cause the surface to be uneven after the film is applied.
Reason two:
The glue is not evenly applied. For example, when applying a large area of ​​film, it is necessary to apply a special primer for wood grain melamine paper. After mixing with water, it should be brushed on the wall, so as to increase the viscosity of the adhesive. But if you don't apply all the details with the roller brush, there may be areas where the glue isn't brushed off.
Reason three:
Apply the film directly without waiting for the primer to dry. In this way, the base layer cannot fully absorb the primer, which will cause that part of the film to not stick tightly, resulting in a hollowing problem.
Reason four:
The bubbles were not discharged in time when the film was applied. The most important thing about the film sticking process is to stick the wood grain melamine paper to the base layer. If the air bubbles in the middle are not eliminated, or the edge part is not compacted, the surrounding air will run around between the film and the base layer, resulting in foaming.
