Can you glue plasterboard to ceiling?
Also asked, can I plasterboard over an existing ceiling?
It is possible to fix plasterboard over an existing ceiling, but you'll need to determine where the joists are first. Downstairs you'll have to prod the ceiling with an awl or lift the floorboards in the room above. Mark the joist gaps on the wall with chalk and you're ready to go.
Similarly, what is the best plasterboard for ceilings? Replacing old ceiling made of lath & plaster, replace it with plasterboards and then skimm over it, for both upstairs and downstairs ceilings. Now which depth should I get, some suggest 9.5mm as they're mainly used for ceiling and the larger verison for walls, but then again others say 11.5 is now often used.
In this way, can you stick plasterboard with bonding?
Dot and dab is used where there is no stud wall to screw (or nail) the plasterboard to. It is much quicker to use a direct bond to stick the plasterboard directly to the wall rather than having to build a stud frame first. It is a very quick and effective way to dryline an internal masonry of brick wall.
Does plasterboard need to be skimmed?
The stud partition walls, and often the inner faces of the outside walls too, are lined with plasterboard, but this is not skimmed with plaster. As you have discovered, plasterboard is very absorbent (so care should be taken not to get it too wet, lest it loses strength), so it has to be sealed.
