Just plasterboarding a new extension, catnic lintels have been used over two windows and doors. Using 27mm insulated plasterboard around these reveals, what is best way to secure these boards on the lintels at the top? Thanks,
Sure, see pic attached. Its the one with the holes, was thinking just plasterboard adhesive but wasn't too sure whether there's a better way?
Just dot and dab it, fit the head first then prop it gently in the centre then dab the side reveals on to hold up the head. Couple of hours and it will have gone off.
As @Jord86 says. Those holes are (partly) designed to give the plaster/adhesive something to grip onto.
