Second-hand house decoration paving wallpapers need to pay attention to the problem

The second-hand house is wallpapered, and it needs to be sanded to apply the wallpaper base film before it can be constructed. In principle, the wall surface can be flat, dry and evenly colored. If it is a cement wall or a brick wall, because it is relatively flat, as long as it is flattened with putty, a thin varnish can be applied to the wallpaper. Gypsum board, plywood and blockboard need to be seamed and then leveled because of the seams. The seam can be added with white glue and water (vinyl acetate resin), and then mixed with the plaster to make the seam firm and not crack. The putty used for batching should be added with a small amount of white glue for sanding.

The wall generally has a powder wall and a light wall. The powder wall is a wall with a weak powder. The sanding should be removed, leveled, and the base film can be applied to the wallpaper; the light wall is very smooth and does not absorb glue. It is not easy to dry, and then the force will drop, so it needs to be sanded before it can be wallpapered.

The purpose of the base film is to cure and protect the surface layer of the putty, and also to strengthen the waterproof and anti-mildew function of the bottom of the wall, but it is necessary to wait until the putty is completely dry to be painted. (The base film is an enveloping product that is easy to dry and is a substitute for traditional varnishes). The function of varnish and sealer is to cure and protect the surface of the putty, as well as to enhance the waterproof, mildew and alkali resistance of the wallpaper. Painting should be carried out after the putty is completely dry.

Second-hand house wallpaper, in addition to the above points, we must also pay attention to any wallpaper wall covering can not be immersed in water construction, the wall must be brushed before the construction.
