We painted a room about 8 years ago. I'm pretty sure we put latex over oil-based paint. Over the years there would be some orange-ish drips that would appear. We thought my son was throwing food at the wall, like spaghetti sauce or something. We were taking things off of the wall and some of the paint just started peeling off in big sheets. After some googling my wife found that old oil-based paints had some sort of linseed oil and that it can seep through latex paint, especially in hot and humid rooms. Marky would keep his door shut 99% of the time and it would get so hot in there so it kind of made sense. Basically what I am asking is what do I need to do to paint over the oil-based paint so that the modern paint will stick and won't allow oils to seep through again? | ||

I would use a 100% acrylic primer first because these primers bond very well. I'd suggest lightly scuff sanding first. This can be quickly done with a pole sander. Then recoat with a 100% acrylic finish paint. No car is as much fun to drive, as any motorcycle is to ride. | |||

I would suggest Zinsser odorless oil primer. Then paint whatever you want over it as it is a wonderful product for mating just about any paint, oil, latex, acrylic etc. to whatever underneath. Do this after you remove whatever is loose underneath, ie the sheets of paint peeling off. | |||

Zinsser BIN primer to be exact. You have to apply quickly and evenly as it dries very fast - alcohol based as I recall. It is also a great sealer for wet areas, where I use it the most. | |||

Water based latex over oil based is not a problem, but requires good prep and procedure. I'm guessing that the previous paint in the room was not prepped properly (washed, roughed up with sandpaper), not primed, or maybe both. Your paint is peeling off because there is no adhesion, and good prep of the surface and a quality primer will take care of that.

Kilz or Zinser. If you do Kilz get low odor brand and wear a respirator. It is a great sealer. | |||

First, you need to clean and prep those walls and get anything loose and peeling off. Then scrub. I would advise Kilz Original, it’s an oil based sealer/primer that seals up all sorts of stains and issues and works really well. Then regular high quality latex wall paint. The woman who lived in this house for 60+ years before we bought it from the heirs must’ve smoked like a chimney in the kitchen, and it stained the ceiling of the hallway nearby brown. I used a couple coats of the Kilz and it completely sealed all that out and allowed me to repaint with white ceiling paint and haven’t had an issue since. It’s pretty thick and tends to spatter when using a roller so you’d have to cover things really well but it’s pretty damn good stuff that WILL NOT let that stuff seep through ever again. | |||

Thanks. We did use Kilz in the bathroom. Should have used it everywhere. Looks like it’s going to be a bit of work. Thanks everyone. | |||

And you will have to determine if the paint that hasn’t peeled is latex or oil. You can’t do oil over latex. But everyone else is right. Clean, sand, prime , paint And I’m another one to say-use Kilz "Violence, naked force, has settled more issues in history than has any other factor.” Robert A.
