You can spatula on a thin layer of drywall mud and then once completely dry lightly sand with fine sand paper wrapped around a wood block to even out. There will be mud dust doing this but all you have to do is cover up furniture, etc. and be sure to have the doors closed to other rooms. I've done this a couple of times in doing such minor drywall repairs and it works well. If you use drywall tape you're going to have to mud anyway (and actually have to use more mud) so why not save a step? ;-) Also, it's quite alot more expensive and time consuming to replace the drywall, tape all the seams, mud and then sand twice because you have to use more mud (sometimes dry, sand, apply a second coat, dry again and sand again) on taped seams.
P.S. Always wear a doctor's type mask when sanding so the dust doesn't get in your lungs.
Here's an answer from my carpenter of 20 years husband: "If you are going to paint it, you could tape over it, but if it's no big deal, I'd replace it, because you'll get a smoother finish."

I recently removed some very old and very adhered wallpaper in my kitchen. Despite my best efforts, there are large and small areas where the top layer of the sheetrock came off with the paper. How do I prepare these areas for painting? I am afraid if I just sand and prime these spots the primer and paint will just be sucked up by the gray paper-like substance that was exposed. Can someone advise? Thanks.

I live in a double wide mobile home. The walls are sheetrock that was made with vinyl wallpaper already on it. The dog tore up a small portion, the vinyl come off and left just the drywall paper. Can I mud that portion of the wall, sand, smooth, and then paint the whole thing? Will the mud adhere to the paper of the sheetrock OK?

I have my doubts that the mud will stick to the vinyl; it needs an absorbent surface. If you want to mud over the vinyl you are going to have to rough it up to remove the plastic coating. Rather than mud over vinyl I would suggest you cut out the damaged panel and replace it instead of trying to repair it if you can, since it has the vinyl covering. Just my opinion without seeing it in person. Good luck. (03/23/2010)
