Yes, wallpaper can generally be applied over painted walls, as long as the surface is in good condition.
The paint should be clean, dry, smooth, and firmly bonded to the wall. Any flaking, peeling, or glossy finishes should be sanded down or prepared to ensure proper adhesion. In some cases, a light sanding or primer may be recommended to improve the surface and help the wallpaper adhere correctly.
If the wall has been freshly painted, it’s important to allow adequate drying and curing time before installation.
