Can exterior wall finish be used as basement membrane?

No, the external decorative wall can't be used as the basement membrane, and their functions are completely different. Fixing the wall makes the base layer compact by bonding, which improves the interface bonding force, improves the bonding strength between mortar or putty and the wall surface, and prevents hollowing. Professional alkali-resistant, moisture-proof and mildew-proof basement membrane wall treatment materials can effectively prevent water and alkaline substances from leaking outside the construction base. The wall has excellent permeability, which can fully penetrate the surface of the wall base material, and is suitable for the base compaction treatment of brick-concrete wall before plastering or batch scraping putty. Wall reinforcement can improve the adhesion of smooth base, which is an updated product of traditional building interface agent. Wall furniture is also suitable for the bonding of wall cloth and wallpaper. Because of convenient coating, thin film and suitable initial viscosity, it is especially suitable for the smooth adhesion of wall cloth and wallpaper, and it is not easy to produce dead folds and bulges. It can also be used to "roughen" the surface of the substrate.
