Wallpaper on Textured Walls
Can wallpaper go on textured walls?
Light texture may be workable, but heavy texture can reduce adhesion and show through the mural. Peel and stick wallpaper is especially sensitive to surface texture.
Best solution
For the cleanest result, smooth the wall first. Skim coating, sanding, priming, or professional wall preparation may be needed depending on the surface.
When to test first
If you are unsure, test a small sample area before ordering a full wall. A little preparation can save a large installation headache.
