We are redoing our hall bath. When we redecorated about 8 yrs ago, the original paper (1983) was impossible to remove, must have been put directly on the drywall without sizing, so our paper hanger put the new on top.

The new stuff was easy to remove. Now we are left with the original problem. The old paper has no texture; almost as if it was the drywall backing, and not wallpaper, no tears or holes. What seams that could be found were spackled and sanded when the other paper was put up.

Trying to get the paper off will definitely ruin the drywall.

Can GARDZ or KILZ be used over the old paper and then can we paint? Or do we have to remove the old and resurface or replace the drywall?

TIA
