Wall surface requirements when wallpaper is pasted
At present, the home decoration has used a lot of wallpaper. Before the construction of the wallpaper, if the wall has been over-exposed, it is best to use a fungicide for special treatment to kill mold; if the other side of the wallpaper is a bathroom, the bathroom interior wall must be used. The waterproofing agent is specially treated, otherwise the wall will be damp for a long time and the wallpaper glue will be invalidated. Before the wallpaper is applied, the wall treatment must be smooth and clean. If there are irregularities or cracks on the wall surface, use a blade to remove it, and use a putty to smooth it. After drying, use sandpaper to polish it. When it is used for large-area wall treatment, it is best to use old powder and cooked rubber powder to make the wall firmer. Small area For example, when filling the seam, use gypsum powder and add some oil to make putty. The best way to do this is to brush the wall up to two times to varnish, to do wall protection and to protect against moisture. After drying, use sandpaper to polish it gently. Do not brush more oil. This will cause the wall to be too smooth, which will make the wallpaper not stick well and shrink during the drying process to produce seams!

Painting should be carried out after the putty is completely dry. 4.
