Over-working of painted or wallpapered interior plasters with lime plaster

Mineral or organic plasters with non-elastic coatings can be over-worked with textured lime plasters without difficulty. Wallpapers must be removed beforehand, as they do not have the sufficient load-bearing capacity for plasters and common wallpaper pastes do not have sufficient strength when wet (exception: firmly bonded fiberglass wallpapers; refer to the application tip "Over-working of fiberglass wallpapers with lime plaster".
