Hello
Several months ago, I drywalled, taped, mudded, and primed a couple of bedrooms. They looked fine until the last few weeks. All of a sudden, I can see a lot of the seams, both tapered and butted, through the primer. The tape itself isn't peeling or blistering, and the drywall itself isn't loose. Rather, it's one of two scenarios...I can either see the crease (and only the crease) along the length of the tape, or the crease has become slightly recessed, forming a very shallow, narrow valley (I think it depends on which way the crease was facing when I first laid the tape). Some - but not all - of these seams have a hairline crack along part of their length.
Can I just add a thin layer of setting-type joint compound for either case? Or do I need to add a layer of tape, and then the 2-3 coats to feather it out? If so, can I add the tape on top of the primer, or do I need to tear out the existing tape and sand the area down?
Thanks for any advice
