Repainting attic room
Bought a tiny house and need to repaint the attic which the previous owners turned into a bedroom, walls are satin, great job, looks professional. While home was on market vandals broke in, partied, and threw around cans of stored paint and ruined about 1/4 of the room (And the carpet). I have a very close match in flat. Is just sanding ok, or do I need to prime as well?
