TEMPERATURE and humidity FLUCTUATIONS

COVERING OLD WALLPAPER WITH NEW
Do not use a wallpaper to cover old wallpaper. Peel and stick wallpapers are to be installed on painted walls, not to cover stains, or previous wallpapers. They can either fall off, or stick so strong you won’t be able to remove it. The outcome can be unpredictable.
ATTACHING ELEMENTS TO THE WALLPAPER
All elements you want to hang on a wall with wallpaper need to be physically attached to the wall using nails or screws. Never glue baby signs, decor or shelving with double sided tape to a wallpaper. The wallpaper will fall off along with all heavy elements attached.
