Due to a roof leak, part of the bathroom ceiling (plaster and wood lath) collapsed. The leak has been repaired by a roofer. For a break on his rent, my son offered to fix the bathroom ceiling. He gets a break on his rent and I get to help him for nothing. Go figure.
My son used plaster washers to secure the remainder of the plaster to the lath and filled in the parts that were missing with drywall. We are now at the stage where we will be putting 1/4" drywall over the entire ceiling.
The problem is that neither of us are that good at taping, especially the ceiling/wall junction.
Suppose we were able to get a nice tight seam between the new drywall ceiling and the walls. Would it be such a terrible thing to caulk the ceiling/wall junction instead of mudding and taping it? We need 2+ sheets of drywall, so we can lay it out so that the tapered edges of the drywall will be in the field, not against the walls.
Nothing else in the bathroom is anywhere close to nice, so it's not about making it look perfect, it's about getting it done and painted.
Note that I am only considering caulking the ceiling/wall joints. The 2 seams on the ceiling itself will be taped.
How bad of an idea is this?
