Can I apply wallpaper directly over old wallpaper?
It is generally not recommended to apply wallpaper directly over old wallpaper, as the weight of the new wallpaper can cause the old wallpaper to peel or loosen over time. Additionally, the adhesive on the old wallpaper may not be strong enough to support the weight of the new wallpaper. It is best to remove the old wallpaper and prepare the surface before applying new wallpaper for the best results.
