What to use to Fill Gaps Around Door Frames? Ask your questions and find answers on many subjects relating to plastering and dry lining

[Thediygirl]

Hi there. I've just added plasterboard (on a frame) above my new door lining...should I fill the gaps around the door lining with concrete or hardwall plaster? I'm not sure when to use concrete and when to use hardwall plaster? The gaps are about two inches (as brickwork came off when we removed the old metal door frames.

Thanks!
