All
As part of a drylining/insulation project I had to cut back some of the plaster and now need to patch it up (i'm doing this as I need to plaster behind the radiator and want to fix to solid plaster rather than board).
Do I need to seal the exposed brickwork first before patch plastering? I was thinking of using PVA to seal - how diluted should it be and how long should i leave it to dry?
Thanks in advance
