What white paint doesn’t turn yellow
Use polycrylic instead of polyurethane.
Do not sand with any clear coat finish. It's made to protect the paint/stain.
Hey Jim, chalk paint does not need a clear coat finish. Chalk paint is supposed to be waxed. The "chalk" additive is causing the yellowing.
Good Morning Barb,
It is not the poly's that is causing yellowing. What happens is chalk paints tend to be porous. When the poly is applied it wicks up the tannins, stains etc thru the paint and causes the discoloration. We have created a product to prevent this from happening. If you are unsure of a piece of furniture and you think it might have nicotine, tannins, stains etc., you can use BOSS. Stands for Blocks Odors, Stains and Stops Bleed Thru.
Hope that helps! Teri -

Never had an issue with this over white.
I read that yellowing is not so much a paint or sealant issue as it is the material you're working with. Wood releases "wood byproducts" through the paint/sealer, which in turn causes yellowing. Different wood types cause more yellowing than others. But if you're painting formica or plastic, or something similar, I don't believe the yellowing will occur. We're in the middle of painting our formica cabinets white and I was very concerned about this issue, so I did lots of research. Hope this helps! Blessings!
I used the Polycrylic and it yellowed, had yellow streaks, on a white chalk painted piece of furniture. I repainted and waited 2 days for paint to dry. I then applied the Polycrylic and this time it didn't yellow. BUT, I found that applying the Polycrylic not too thick and slowly applying the Polycrylic is the key. Also, waiting until the paint is thoroughly dry is very important. I realized I made mistakes the first time when it yellowed; I only waited an hour for paint to dry and I was applying it quick so the application was thicker. When I waited the two days for paint to dry, took my time to apply the Polycrylic and applied thinner even coats, it did not yellow.
sometimes it yellows over time also, just a heads up, it's not always immediate. I have used multiple products they all yellow on certain woods that release tanins
also I have used shelac on items pre painting to avoid yellow with success
From what I have noticed in looking at MANY water based polyurethanes is that the ones that won't yellow actually state that on the can. Not just "crystal clear", but it will actually say non-yellowing.
Chalk paint is not supposed to be poly'd. Chalk paint needs to be waxed. The tannins in the chalk paint cause the yellowing not the poly.
Will water based poly resist nail polish and acetone. I want to finish a wooden (Oak) table to use as place she can do finger nails on.
Can polycrylic be used on oil base painted tile? I know painting tile sounds crazy but it happened lol. Looking for away to seal it extra
In terms of which poly doesn't turn yellow, you want to use a high grade water borne poly, such as Bona Traffic HD. Not just a water based one, but a high grade one. Mid to low grade water borne poly will turn wood a bit yellowish and more yellowish over time. You can read more about that here. Which polyurethane doesn't yellow?
That aside, you are not supposed to use a polyurethane over paint and if you call the manufacturers, they will say "you can try it, but we don't guarantee anything." Instead, you should be using a different type of paint - you can use Minwax Polycrylic.

I have a homemade kitchen table, made out of natural pine. I was wanting to stain it first with water based minwax honey oak and then do a watered down white wash over it (and wipe off) with a Valspar latex eggshell paint. If I use polycrylic over the top (to protect from water rings from glasses).....will this yellow over time too?
I have oak cabinets that I sanded and wanted to apply a sealer what should I use so it doesn’t turn yellow
