Looking to see if anyone has had this problem out there. I am a carpenter by trade and I have been doing my own contracting over the past two years. I have been working in the trades since 2003 as an employee, sub-contractor, and now recently contractor. I do most of my work myself. I hung a basement with ULW 1/2" sheetrock from USG I think, (not green board, maybe my mistake). I had framing 16" o/c with all the drywall glued and screws 12" apart. 4 to 6 months after project completion, customer showed me screw pops. And i'm talking they were everywere. I believe every screw in the field had popped. I am still trying to wrap my mind around it. Has anyone had this problem or ever seen such a thing? I am at a loss as where to investigate, but I assume it is moisture related. Thinking the best fix is to hammer, skim, prime, and repaint. Thanks.
