Our 2-car attached garage (my woodworking shop) of our 20-year old home must not have any insulation above. Either that or the taping job on the drywall joints must be substandard. Perhaps both."Stuff" in now falling on my tools. The ceiling is trowel textured so it's about 1/8"+ thick everywhere. Whereever there's a joint, and I mean every(!) ceiling joint in the garage, the taping has detached from the drywall. By grabbing loose ends of the paper taping, I can peel it off. The texturing that was applied directly to the drywall stays put. So, by peeling the loose stuff off, I end up with ~3" wide strips running in both directions across the ceiling. It's kind of weird looking, because the texturing creates some relief and the peeled "runways" are flat and sunken. How should I repair this problem before repainting the ceiling? Must I retape? I've never done any taping before. Can I just fill the runways with joint compound? Either way, I know I won't succeed in getting a seemless blend into the existing texturing. Does taping have a purpose in addressing expansion, inferring that I should try to retape it? Thanks for all advice. ron Please reply to newsgroup because spammers are killing me.
