Yes, it’s possible to wallpaper over existing wallpaper. However, before wallpapering over wallpaper, consider: Condition of old wallpaper: If the old wallpaper is very damaged, stripping the wall is the best option. Applying wallpaper over a damaged surface will cause the wallpaper to peel. Although, a few loose seems is fine as the base for new wallpaper. Material of old wallpaper: It’s not possible to wallpaper over vinyl wallpaper. Doing so will result in the new wallpaper not properly adhering. Therefore, we only advise wallpapering over non-vinyl wallpaper.  In addition, avoid wallpapering over textured wallpaper. This is because it could result in bumps showing on the new wallpaper. Colour of old wallpaper: If the current wallpaper is dark, avoid wallpapering over it. This is because there is the risk of the old wallpaper showing through. Layers of existing wallpaper: We only advise wallpapering over a single layer of wallpaper. Since wallpapering over multiple layers of wallpaper will result in the wallpaper peeling faster. If you are unsure of the number of layers of wallpaper, peel a small area of the existing paper to check.
