Best way to remove old mastic from behind paneling?

brendainnjOctober 18, 2010

Maybe I should say--easiest, least messy...I've already tried sanding, which worked but was very time-consuming and dirty. It's in my kitchen so it takes almost as long to put plastic over everything. Lately, I've been using a small 1" putty knife, which surprisingly worked pretty well on the thicker stuff. Some of it lifted off quite easily, but I think I've hit an impasse now. Is there anything that could be applied that would "dissolve" the rest of it? I plan to use Gardz when I'm done, but the wall is not smooth enough yet. Would skim-coating work better? I've dinged the wall in a few placed with the knife, nothing major but I will have to patch up some areas. This wall is about 8x8 and the mastic is not over the whole thing, it looks a little bit like someone put Elmer's glue squiggles over it.

Thanks for any help!

Stripping out the drywall and replacing it would be faster than just about anything else, and less work than skimming the area.
