I have installed drywall on the ceiling and taped the joints with paper tape. In one spot, the tape came loose when I painted the first coat of paint and it won't go back. There was probably not enough joint compound under the tape. Is there anything I can do to fix it?
I'm tempted to make a cut in the bulge that sticks out and try to smooth it out again somehow. Any tips? The area is about 2x10cm.
