Do I need to use moisture resistant plasterboard on ceiling when wet plastering on top?
As per title: Do I need to use moisture resistant plasterboard on ceiling when wet plastering on top in bathroom?
Vaulted ceiling has Insulation backed plasterboard that is not moisture resistant. It's all going to be skimmed in the near future.
If it's going to be skimmed over, do I need to get someone to overboard it in green plasterboard before it's skimmed or not?
Thanks guys!

"You don't need it for the ceiling but if you are doing it on the walls, where more moisture is. then you may as well do the ceiling too. It's only a few pounds extra material-wise"

"It is a standard specification to use green moisture boards on bathroom ceilings these days.
You can get away without using green boards if the ceiling is being plaster skimmed but if it's been taped and jointed with filler than a vapour primer / sealer will subsequently help"
