It’s A Misconception That A Liner Will Smooth A Textured Wall

May 25, 2022

A theory has been circulating for decades that a liner disguise texture or imperfections in a wall. A liner is a special paper applied to the walls before the actual decorative wallpaper goes up. It has its purpose – but smoothing walls is not one of them. At least, not in my opinion.

Here you see an area where a pedestal sink has been removed. In so doing, part of the drywall was torn away (the reddish brown area) and the wall surface is left uneven.

I’m using liner in this room for another reason. Here it has been applied over the damaged area. As you can see, the uneven texture of the wall shows right through (we say that it telegraphs ). Once the liner is good and dry, it will shrink and pull even tighter to the wall, and the ridges underneath will be even more visible.
And once the wallpaper goes up, all this will telegraph through the new wallpaper, as well.
Here’s the liner paper I used today. It’s a fairly thick, stiff, non-woven material, so has more ” bridging ” power than other types of liner paper. Still, as you see above, it’s not enough to smooth textured or uneven wall surfaces.
The only way to properly and thoroughly smooth a textured wall, IMO , is to skim-float it and then sand it smooth, and then apply a wallpaper primer. Please do a Search here (upper right corner) to find previous posts on this process.
