Ok, I had a professional come in to raise my bathroom ceiling 6". I can tape & bed so I told him to just put up the drywall. The edges are uneven and there are large cracks (1/4 - 1/2") between joints and edges. Is it better to sand down the uneven edges? And what is better to fill in the gaps - caulk or pieces of drywall glued in? Or should I just tape it and try to compensate with layers of mud.

HELP!!!! So I have a new baby on the way and decided to enclose the loft for our nursery. This is my first experience with drywall so please pardon the ignorance. We opted to use the paper bullnose corners and come to find out we applied the bullnose incorrectly ... and that is we didnt pretreat the paper before applying... so in other words we applied the paper bullnose dry then proceeded to apply the compound to the exterior of the tape ... everything looked great until it began to dry. We are now faced with 3 bullnose corners that have bubbles up and down both sides of the corner. My question is whats the best way to fix this issue? Do we rip them out and start over? Can we apply the 2nd & 3rd coats over top of the bubbles or will this cause later problems? do we cut out the bubbles? Suggestions please. :wall:
