I applied 2 coats of paint and primer and let dry for 2 days. I then applied a coat of spray on polyurethane , satin finish. After it dried some areas were yellow. I then sanded it down and applied another coat of my color, let that dry 2 more days. I bought a can of minwax satin finish polyurethane and applied 2 coats. Again there are yellow areas. I have down several painting projects and this is the first time I have had this problem.

What caused it and what should I do now to get rid of the yellow areas?

Thanks, Sandy

Oil-based polyurethane causes yellowing of white paint. It looks like the Minwax Satin Finish Polyurethane might be oil based, true? If so, I'd sand it down again (annoying, but necessary) and try again with a water-based poly. Then again, you might do well to just paint a few coats of satin finish paint instead of poly it, depending on what you're painting/what color you're using but that won't protect well if it gets a lot of use. Hope that helps!

The polyurethane was actually water based, not oil. I think i will just sand and apply several more coats of the color. If you have other suggestions I;m open. Thanks Sandy

Oh—it is water-based after all? Well, I'm stumped. I know white paint can be picky about polyurethane but don't have personal experience working around it. Anyway, if you find something that works, share the knowledge.

Does polyurethane turn yellow when put over wood stain?

I want to paint and poly my cement floors but am hesitant cause I'm afraid the poly will yellow over time. Is there anything else I can use to protect the floors that won't yellow?

Buy the epoxy and do it right. Polyurethane isn't going to hold up well. And all polyurethane will yellow. Whether it be water based, oil based, oil modified water based, etc. They'll all yellow. Polyurethane sucks. Esp when you paint something really nice, then make the mistake of thinking, "Oh, I'll put a coat of poly on it to protect it." Wrong move... Every time.

I sanded the table but the polyurethane stain penetrated the white paint underneath the table looks brownis

Birchwood being used to build wall unit. Will be stained with MINWAX when done. Debating if I should leave it without polyurethane or polycrylic so it shouldn't yellow. Room gets very dusty not sure how well plain stained wood will hold up from constant cleaning.

if you wet the bare wood [birch white pine] that amber color will be the same as when you apply an oil based poly! to keep the hue the same on a softwood use a water based acrylic now on hardwoods[hick oak] both poly and acrylic will shade the same as when you dampen the to get the hue look !! now let the wood dry before coating

Water based poly will show yellow if the application is put on too thick rather than thin coats...especially over white paint, sand down and start over,many coats and patience is better than one thicker coat...


08:14AM | 06/09/19
Both epoxy and poly yellow. In order to keep both from yellowing is thin layers and sanding. Be patient use thin coats sand with steel wool pads or 380-400 sand paper. Clean very well after sanding. If paint is water base use water base poly. Hope this helps.

I worked my booty off painting my kitchen cabinets white and then giving them a antique look. We are remodeling our kitchen completely so I haven’t finished them yet,
I really want to protect them with a top coat but I’m getting so many mixed messages of dos and Don’t’s yikes!
I want durability and no yellowing but I am at a loss truly!
Use polyurethane water-base, use polyacrylic water base,
Don’t use any top coat ,what should I do? My paint was water based and I know when I was doing the antique on them they won’t last 5 years before they look horrible so they will need something to protect them please any advice will be greatly appreciated and ASAP!! Thank you!

I actually use polyurethane for stones. Will this yellow as well?

My white washed wall and white cabinet have turned yellow after polyurethane was applied. I'm so disappointed. Now I have to sand again and repaint. I wish someone would've told me ahead of time.

I used (all) water base primer, paint & vaarathane poloy - white was significantly yellow within less than 2 months. Never had an issue prior. This was a large project. Now it has to be redone at my cost. Prob will straight paint. Any ideas?


02:50PM | 05/09/20
Have you tried polycrylic? I heard that doesn't have the yellowing effect.

Id like to know the science and actually facts behind the 350 to 400 grit steal wool and thin coats of poly. I think its bs.

Wood choice is big. Oak white oak especially yellows. Hickory, maple. The only wood that doesn't has natural pigments like Brazilian Cherry or walnut. Water base finishes tan which is almost worse. Mutes the grain, i hate water.

If uv light hits the surface you are going to degrade the finish and it will change color. Ive never used it but google says this home mase company called crystal clear or something makes a water base that has uv protection in it... could be worth a look. Says 3 to 5 coats and well.. as a floor guy that is ridiculous. Does say it drys in 2 hours... probably would be fine for cabinetry.

My wood cabinets have turned slightly yellow over the years. Is it due to the polyurethane? Is there a way to get the poly off and get back to the original wood?

I'm thinking of using spreadstone on my old counter top, but don't like the high gloss finish. Would a satin or matte finish work?..hold up?.. or yellow?


01:46PM | 01/27/21
I put the topcoat on counter tops and when it dried some spots were yellow. What can I do about that.

You should apply at least 3 thin layers of a good quality clear coat paint. Not polly. Epoxy will yellow too.

Don’t do it! I’ve been working on my bedroom furniture for weeks! Stained everything white and it looked beautiful....until I used polyurethane (water based). It looks like there’s coffee stains on it now. Gave everything a yellow tint! Unfortunately I thought it was my lighting and kept going with it! Now I have to sand several pieces down again. Lesson learned!!!

Ok, so I've sanded the top surface of the dresser down some,till it's smooth. It was walnut,some one painted over it and obviously used a water based polyurethane coat and it yellowed. It's a nice piece. So I took it down to the point it is smooth now. All I'm going to apply on it is 2 coats of white Hi -Gloss Acrylic good quality paint. I can't see that having any problems in the future as I would if I put a polyurethane coat on. Any Suggestions or advice is appreciated ♥️

Sometimes after you paint, then poly, it pulls out the wood tannins and that is what causes the yellowing. Might try a blocking primer then paint, then a water based such as polycrylic.
