The main difference between peel and stick PVC-free, peel and stick Vinyl, pre-pasted and traditional wallpaper lies in their material composition and application method. Peel and stick PVC-free wallpaper is made without polyvinyl chloride (PVC), offering an eco-friendly alternative. Peel and stick vinyl wallpaper is crafted from vinyl material, which provides durability and moisture resistance. Both types feature a self-adhesive backing for easy application. Pre-pasted wallpaper, on the other hand, comes with adhesive already applied to the back and requires activation with water before hanging. This traditional method offers a secure and long-lasting bond to the wall. Traditional wallpaper has to be installed using a special type of glue (not included), and the result is permanent.
