Hi, I want to fix plasterboad on this door reveals, top and sides, in preparation for room plastering.
It is a cavity wall and the closers are hard plastic but really moves a lot. Even if the plasterboad adhesive sticks on the plastic, the plastic underneath flexes and moves, and so the plasterboard also moves.
At the top there is a standard cavity lintel with polystyrene insulation.
The only solid surface there is for the adhesive is the blockwork on the sides, which is 100mm, and is then followed by 100mm cavity closer or 100mm polystyrene at the top.
I tried fixing the plasterboad onto the blockwork and that was solid, but the part up to the door frame was moving. So i took it down again.
I do not know what to do. Any help appreciated.
