Hi. I'm taking the paint off still however I've had to pull off a stainless steel splashback(?) behind the hob. The adhesive from this has pulled off some of the plaster and some of the paper from the plasterboard. I don't want to replace the whole section so would it be ok to prime these bits with PVA or should I cut out the paper down to the plasterboard mortar and then prime?
I could ignore as the majority of the tile will be fixed to the plaster.
