One、How to repair wall fabric detachment
1、Clean the back of the wall covering and the wall surface, removing any dirt or debris as much as possible.
2、Apply the adhesive evenly to the wall and wallpaper.
3. Allow the adhesive to dry for approximately 2-5 minutes, then apply the wall covering and press firmly to ensure adhesion.

4. After pasting, it is recommended to use nails to fix the top of the wall covering to the wall surface. Allow the adhesive to fully cure before removing it.
Two. What adhesive should be used to fix peeling wallpaper?
Cold glue, also known as universal glue.
The area to be repaired after wallpaper detachment is usually small, so there is no need to purchase bulk adhesive. Using leftover adhesive leads to unnecessary waste, and also requires purchasing additional accessories like rollers, making the process more complicated.
Canned self-adhesive tapes are a good option. Canned self-adhesive tapes mainly come in two types: aerosol and mesh-based tapes. This classification is based on the form of the adhesive dispensed, with aerosol-based tapes having lower bonding strength than mesh-based tapes. Mesh-based tapes can be used for wallpaper application.
If the area of the wallpaper detaches significantly, it can only be removed and re-glued.
