What is the wallpaper construction technology?

First, the most important thing before pasting wallpaper is the treatment of the wall. Wall treatment is a very important link in wallpaper construction, which has a vital impact on the effect of wallpaper posting.

Second, the wall construction requirements:

1. In principle, wallpaper can be pasted when the wall is flat and dry.

2. Wallpaper on the cement brick wall: relatively flat, leveled with putty, and the wallpaper can be pasted with a thin layer of varnish.

3. Paste wallpaper on gypsum board, plywood and joinery board: there are seams, which need to be mended first and then leveled.

Joint repair putty: As long as more white glue (vinyl acetate resin) is added, the joint will be firm and will not crack.

Putty leveling: just add a small amount of white glue for sanding.

4. Adding white glue to gypsum powder instead of leveling putty can speed up drying and shorten construction time.

5. Powder wall wallpaper: that is, there is unstable powder on the wall, and the wallpaper can only be pasted after polishing, leveling and brushing the basement membrane.

Bare wall wallpaper: that is, the wall is very smooth (such as painted wall), which is not easy to absorb glue and dry, and then the strength will decrease, so the wallpaper can only be pasted after sanding.

6. Wallpaper pasting on the painted wall: The painted wall is very suitable for wallpaper pasting, but the wallpaper basement membrane needs to be polished and painted before construction. In fact, the pretreatment of wallpaper wall is roughly the same as painting wall.

7. Before construction, the general wall should be brushed with basement membrane. The purpose of brushing the basement membrane is to solidify and protect the surface of the putty, and also to strengthen the waterproof and mildew-proof function of the wall bottom, but the putty must be completely dried before brushing. The basement membrane is an environmentally friendly product, easy to dry and a substitute for traditional varnish.

8. wall covering can be immersed in water without wallpaper.
