The non-woven wallpaper is reasonably thick in my opinion, and can be mounted easily on a woodchip wallpaper. Since my cats had scratched said Rauhfasertapete in many places, I was interested to see whether the damaged areas would push through. This was not the case. The walls seem truly virginal intact and my cats have fortunately not interested in a non-woven wallpaper.
The provision was not a problem, however, and is easy to handle even for a beginner.
