More Work on Yesterday’s Delaminating Wall

Re yesterday’s post … after I got the wall stabilized, I skim-floated the surface to smooth it. That dried overnight, and today I sanded it smooth, vacuumed up the dust and then wiped residual dust off the wall with a damp sponge, and then primed with good old Gardz. I feel pretty confident that that wall is secure enough to withstand the tension of drying wallpaper. But, just to be sure, I applied a liner. A liner is a special paper that goes on the wall under the decorative wallpaper. In this case, the purpose is to distribute tension so that no stress is placed directly on the wall. So it’s important that the seams of the liner and the decorative wallpaper do not line up or fall on top of each other. This way any tension is dispersed and distributed, and any inner surface that wants to delaminate will be held in place by the layers of paper over it. In this photo, the section to the left has the new white liner, and I am moving toward the right to finish this wall.
t’s important that the liner be flat and that the seams lie down tightly, so no bumps or ridges show under the new wallpaper. I was really pleased with how these seams just melted away.
There are all kinds of liner papers out there. This one is a stiff, somewhat thin non-woven option made in Germany.
Using a liner does add to the cost of the installation, for both material and labor to hang it.
