Nope, sorry, it ain’t happenin.’
The special type of paper called liner is used under some wallpaper s, and serves certain functions. Smoothing walls is not one of them.
If you’re planning to hang wallpaper over textured walls, liner paper cannot be used as a replacement for skim-floating , sanding , priming , and properly prepping the walls .
As you can see in the photo, liner paper shrinks as the paste dries, and pulls tight against the wall. This means that little imperfections will show through.
In the photo above, a towel bar had been removed, and the support bracket had been stuck / recessed into the wall paint , so the indentation and ridges from the bracket were still evident on the wall.
Covering them with a wallpaper liner helped mitigate them a bit … but, as you can see, the raised outline of the mounting bracket is still visible.
The issue is that this raised area, covered with liner or not, will still ” telegraph ” through the new wallpaper, creating a noticeable and unpleasing look.
To properly smooth a textured wall before hanging wallpaper, the surface must be skim-floated with joint compound (also referred to as mud ), sanded smooth, wiped free of dust, and then primed. Now the wall should be smooth enough to provide a good surface for the new wallpaper.
