I love doing electrical, plumbing, carpentry, furniture, finishing ... but I just HATE painting - probably because I'm very slow at it. I have this weird problem that I could use some Wreck Smarts on:
The front foyer of a home is done entirely in drywall. It was initially primed/painted almost 20 years ago and has since been repainted at least once. At one point or another, a leak developed above foyer ceiling. Although the leak was subsequently fixed, it left what appears to be some kind of brown/mineral discoloration on the ceiling and not amount of paint seems to cover it. If I paint it, it dries, and the stain reappears.
Ideas?
TIA,
