I've just boarded a ceiling and two walls with 12.5mm plasterboard and used 1.25" drylining screws. Some of them have sunk quite deep into the board thanks to enthusiastic use of the electric screwdriver. It ocurred to me that I don't know how deep I should go. Presumeably I need to get at least flush with the surface, but should I "break" the paper layer? What if I do, is it really bad news in the sense of the board hanging on?
Many thanks and yes, it is the never-ending bathroom!
The two walls will be tiled full height but I don't know what weight the tiles will be as we haven't decided finally on the design. I have used 1.5" screws on the walls about every 6" or so. In the new shower area I'm going to use aquapanel.
I tried to rely on the driver torque setting but as the studs are original timbers from the lathe & plaster days they are now quite hard, so the torque sensing kind of didn't notice when the screw head hit the plaster board. Maybe I'll just take more care on the remaining walls.
"In the new shower area I'm going to use aquapanel."
Good idea. Don't even consider skimming it. You'll have wasted your money on the aquapanel as you might just has well have used cheaper plasterboard. BTW plaster doesn't stick to aquapanel very well anyway.

another reason the screws will pop is just bad timber work.the reason i dont use 9mmm is that i board for a living,by using 12mm board they are easy for me as when on my own i dont use a deadman and the 12mm are more ridged.try putting soundblock up on your own.
