In my apartment, I have a suspended ceiling. One layer of drywall is mounted against metal studs, but now I’m thinking of installing another layer because there’s no other nice way to cover a large hole in the ceiling. So to my question...
When I put up the second layer of drywall: Do I have to place the screws in the studs, or is it enough for them to attach to the first layer of drywall?
I've read somewhere that it could work to glue the panels up as well, but don't you still have to screw them in too? Is a fewer number of screws used per panel if you choose to glue? Or what is the point of gluing up the panels?
You must screw into the metal studs. The plaster cannot support the weight and is highly sensitive to overtightening. A screwdriver is a no-go.
With a 50mm screw in the metal stud, it tightens just right.
It is possible to glue as well, but it requires quite strong types of glue that smell a lot, and you need a plaster lift to get the board up and hold it in place long enough for the glue to take hold.
There is a hole across the room that was previously covered with an ugly chipboard. A wall that had been torn down and then the studs have been cut at the height of the ceiling. There is nothing to directly attach a piece of drywall to..
Take the multimastern and cut 14mm off the standing studs and boards. Place new vertical studs (kortlingar) between the standing studs with the bottom edge 14mm above the existing ceiling. Screw a strip of plasterboard into this. Spackle, sand, paint, done!
