I removed the popcorn from my ceilings so I could repair tape seams that had not held. I am working in one BR, and have a question about how to repair several joints in my ceiling.
The sheets are screwed to the joists in the roof. At the bottoms, where the joints are 90 degrees to the joists, the corners were not secured to anything. I cut 13" sections of 2x4 to fit between the studs, which were held in place from the attic. I screwed the drywall to these studs to tie the two edges together.
For some reason, some of the drywall was cracked along these edges. I trimmed out the loose pieces with a razor knife, until I got to solid drywall.
How should I repair these? Just use the common drywall mud, and apply fiberglass mesh tape over them? Should I use any paper tape at all?
Thanks for the help. This job just gets more and more involved every time I turn around.
