Hi All,
I'm about to embark on a project to pull down my existing lath and plaster ceiling and replace with plasterboard, prior to having it professionally skimmed.
I plan to use 12.5mm square edged boards, and would be grateful if anyone could advise on the following:
1) Should the boards be laid with the long edge across, or along the joists?
2) Do all edges need supporting? (i.e - will I have to fix noggins between the joists along each unsupported edge?)
3) I've received conflicting info about what length of screw to use - some people have suggested 38mm, some have said not to use anything shorter than 50mm - who's correct?
Thanks for any advice!
Dave.
