Hi I hired my buddy who is a union framer/drywall person he has over 20 years exp but he screwed wonderboard in my shower rebuild and I'm looking at the corners and not too pleased. Wondering if anyone can tell me if I need to replace or will thinset fix this issue.
I also wondered if I can take my 4.5" angle grinder with diamond blade to cut the corner straight and then fill with fiberglass tape and some kind of a filler.
