I recently bough a new house and it came with a fair bit of plaster damage in the walls. The biggest problem area is this patch of water damage where the gutter leaked down the exterior wall. This damage appears in two rooms, one of which has been painted since the damage happened.
I've never done a plaster patch before. I think I understand the process and have the tools I need. I should be able to fix the damage in the unpainted room, but I'm wondering if I have to scrape away or strip the paint before I patch the painted room? If I do, does anyone know the best way to go about doing this? Is this even worth worrying about?Thanks so much.
