Hello all
I have a bathroom which has insulation backed plasterboard on the ceiling, I'm going to need to put new plasterboard under the existing plasterboard. What would you suggest I use to fix the new board to the old one?
I'm guessing a screw just through both bits of plasterboard won't be sufficient, will I need a very long screw to get it up into the wood above? If I do this what are the reasons for not using a standard easily gettable long screw over a long plasterboard screw?
Sorry for all the questions, I've been doing some searching and can't find too much.
