Can you use oil base polyurethane over latex paint?

Answer 1

Yes, you can use latex paint over poly but you have a few steps to do before you can apply it. First, whether the poly is oil or water based, you'll want to sand it to give it a tooth (something to grab onto). Make sure to wear a mask and goggles. Next, prime the surface you want to paint. You can fill any hole or fix imperfections over the primer but you'll have to prime those areas again if you do. After you're priming is done, you can roll out your paint. Quick note: if the poly is oil-based, I would use an oil based primer (Zinsser"s bin 1-2-3 oderless oil primer, white can with yellow flag on it). You can roll latex over this primer.

Answer 2

after the latex or other water borne product has cured, generally specified on the label, the polyurethane cannot penetrate or reactivate the paint. simply put, yes. but i recommend an acrylic top coat instead. they are equally as durable and wont yellow like urethane's and other products containing nitrocellulose.

Answer 3

Yes, you can use an acrylic, high bond primer over dulled and clean polyurethane. Allow it to cure fully for at least two weeks prior to putting the item into service or attempting to clean the surface. Resist the urge to pick at it.

Answer 4

No, latex paint is made of water and polyurethane is oil based. If you know the saying, "Oil and water don't mix."

Answer 5

Yes, after ensuring that the surface is clean, oil-free and dull, apply an acrylic or oil-based primer as a bridge to accept the latex paint.

Answer 6

Yes, especially if you use a water based polyurethane.

Answer 7

Why would you WANT to do that? The performance of polyurethane paint is so far superior to that of latex it's not even funny.

Answer 8

Yes, you can.
