Wallpaper and Wallcoverings - painted wallpaper removal

My half bath has wallpaper that has been painted & primed over. It is peeling and I'd like to remove it completely, but everytime I try I end up peeling away the top layer of drywall. Am I having so many problems because it is painted? I've tried peeling it from where it is already curling, I've tried cutting a shallow line in it with a razor, and I'm about to try one of those scoring tools followed by wallpaper removal. My fear, of course, is scoring the wallpaper only to take the drywall off again. Is there anyway to prevent that from happening? Hubby and I are thinking of just putting bead board all around the walls to hide them rather than deal with the problem.

Any help is appreciated.

The problem is that the original wallpaper was probably put up without a primer. You should strip the paper using the directions contained in the FAQ top post on this forum. Repair damaged spots and prime with a primer/sealer such as Zinsser Gardz.

Exacly how do I repair the damaged spots? Every spec of wallpaper I tear off is taking the top layer of drywall. By the time I'm done stripping (following the instructions) I'll have no top layer of drywall left.
Thanks.

At this point I would attempt to seal over the paper with an oil primer, then smooth out seams and rough areas with joint compound.

After this is done, reprime with a latex primer, and paint it. Or reprime with a wallcovering primer, and rehang it.
