I have to put up a new plasterboard ceiling in our kitchen (3m x 3m) and for a variety of reasons I will have to put new plasterboard over the existing plasterboard ceiling.
I have never done this before and will probably only have my son to help me. I have located the joists and marked their locations on the wall and I intend using 40mm dry wall screws.
My questions are related to how best to handle and fix the new plasterboard (12mm).
1. Should I try putting up the board as it comes i.e. 8 x 4 sheets or should I use smaller panels?
2. Would it be of benefit to apply builders adhesive along the edges of the new board to help it stick to the old board?
Any help gratefully received.
