How to Prepare Your Wall Before Wallpaper

A beautiful mural starts with an honest wall.

1. Clean the wall: Remove dust, grease, and residue. Let the wall dry completely.
2. Repair damage: Fill holes and cracks, then sand smooth. Raised defects can show through the mural.
3. Check paint condition: Wallpaper needs stable paint. Peeling, chalky, or damp paint should be fixed first.
4. Prime when needed: A suitable primer can improve adhesion and make future removal cleaner.
