For the Easy-Hang and Heavy Vinyl materials, please use Paste-the-wall adhesive for non-woven wallpaper. The paste is applied on the wall and the dry wallpaper drops are placed on top. Please note, Paste-the-paper and All purpose adhesives are not suitable. Your local hardware store should stock Paste-the-wall adhesive. The Removable peel and stick wallcovering material is self adhesive. This wallpaper has a backing that you peel off. The wallpaper drops are then applied directly to the wall and no glue is needed.
