One. What causes the detachment of wall coverings?
1、Adhesive issues. Wall fabrics require specific adhesives; general wallpaper adhesives cannot withstand the weight of the fabric, resulting in detachment.
2. Excessive moisture content in the wall. After the membrane is applied, water continuously seeps out from the wall. During the drying process of the membrane, continuous water seepage creates numerous capillary pores on the membrane surface. After construction, alkali from the wall penetrates through these pores, corroding the wall covering.
3. The wall surface has excessive alkalinity, and the wall surface is not properly treated. The primer or varnish is too thin or leaking, preventing the formation of a protective film on the wall surface. This prevents the isolation of alkalinity in the wall from external penetration, which can corrode the wall covering and affect the adhesion of the adhesive.
Two. What should I do if the wallpaper is peeling off?
1. Check if the issue is with the wall surface. If it is, the only option is to remove the damaged section and rebuild the wall before applying the wallpaper.
2. If the issue is related to the adhesive, simply replace it with a suitable adhesive.
3. Regardless of the reason, it is recommended to consult with professional experts to identify the cause and implement a comprehensive solution.
