  • Detail

1. In principle, the wallpaper can be pasted when it is flat, dry and uniform in color

2. Cement and wall tiles: they are relatively flat. Use putty to flatten them, and then apply thin clear paint to stick the wallpaper

3. Gypsum board, plywood and blockboard: there are joints, so fill the joints first and then flatten

putty for joint repair: add more white glue to make the joint firm and will not crack

leveling putty: just add a small amount of white glue for sanding. Too much and too hard white glue is hard to sand, and too little and too soft glue is easy to crack

4. Gypsum powder plus white glue instead of leveling putty can speed up drying and shorten construction time

5. Plastering: that is, if there is unstable powder on the wall, it should be removed by sanding, leveled, and painted with clear paint before pasting wallpaper

light wall: that is, the wall is very smooth, not easy to absorb glue, not easy to dry, and the bonding force is reduced, so it needs sanding to stick wallpaper

6. Function of varnish: the purpose of varnish is to solidify and protect the surface layer of putty, and it can also strengthen the waterproof and anti-virus functions of the wall bottom, but the oily varnish can only be applied after the putty is completely dry

7. The pretreatment of the wall with wallpaper is basically the same as that of the wall with paint, so the painted wall is very suitable for changing wallpaper, but it needs to be sanded
