First post on the DIY forum... We just bought a house (yey!) It's about 30 years old, the bedroom is covered with outdated wallpaper, we are planning on remove all wallpaper and put on some good quality paint. After tearing half of the wall in one bedroom, I find that there are plenty mildew growing there, and some of the top surface of drywall got peeled off with wallpaper.
Previous owner apparently just taped tearing wallpaper using packing tape and left the mildew problem there untreated...
Can I just skim coat the old drywall with dry wall compound and prime it to seal what's under and then paint, or do I need to actually tear the old drywall and install a new one? (I'm a novice at home improvement and never installed any drywall before.)
Is it necessary to kill the mold first (with a good sponge&wipe with bleach and water mix) or can I just skim coat it directly without worrying the mold?
(Tested for lead and the drywall is leadfree.)
Thanks for your help!
