Why does wallpaper need wall prep?
Wallpaper shows the wall underneath it. Nail holes, dents, adhesive residue, texture, torn drywall, and uneven patches all telegraph through the finished paper or create seam and adhesion problems. Before installation, Tyler assesses the wall, removes residue when needed, patches damage, skims where needed, sands smooth, and uses primer or sealer when the wall and material call for it.
