Somewhat OT: A Painting Question

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,

Shellac let dry, and repaint.

There are Kilz and/or Zinsser primer that are shellac based. Get one of those and prime the area... it might take two coats.

Isn't Leon our local Zinsser B-I-N advocate? :-)

Well, if he isn't, I'll be glad to take over :-). I've used B-I-N on stains left by roof leaks that kept re-appearing until I used the B-I-N.

Great stuff.

On a related topic, I'm replacing some trim boards on our place. The originals were rustic, so I bought cedar fence boards and cut them to width. I painted them first with B-I-N on all sides with multiple coats on the end grain and an extra coat on the back side. Then I painted the other 3 sides with the trim color and installed the boards with screws.

That's one job I don't expect to have to do again!

KILZ or another brand of shellac type sealer.

Kilz the oil based version best bet, but I hid some cieling stain recently with Kilz water based primer.

What he said. You need a stainkiller paint or primer of some sort, anyway. Doesn't have to be Kilz brand specifically, though that's the easiest one to find. Sherwin-Williams makes one that they call "StainBlocker" or something similar, which I've used with great success. Kilz also works very, very well.

Doesn't have to

Sherwin-Williams makes

great success.

And just plain white shellac works too (or even amber).

Careful. If you mean the Zinsser white and amber shellacs, they contain wax. That may or not be a problem, depending on what finish you overcoat with. SealCoat is a lot safer. And I suspect B-I-N is dewaxed, although I haven't checked it.
