The Best Polyurethane That Doesn’t Yellow Reviews
Polyurethane types that are much clearer and lighter tend to yellow the least. With minimal exposure to the sun’s UV radiation, the yellowing may remain negligible and imperceptible to the eye.
I have also noticed that cheaper water-based polyurethanes also tend to yellow more than the premium types. So if you are looking for a non-yellowing poly, you may want to spend slightly more money for the desired outcome.
Based on our research, here are the best non-yellowing clear coats.
1. Best clear coat for wood – Bona Traffic HD Commercial Extra Matte
While Bona Traffic HD is relatively more expensive than most of its water-based peers, it is by far the best non-yellowing option. The coat stays clear and preserves the natural look of your wood, especially where the sun exposure is minimal.
The poly is made of top-quality polymers, making it the most durable option I have found. This durability will go a long way in saving you money in the long run.
I loved Bona Traffic HD for its low VOCs profile. VOCs are the volatile organic compounds added to paints and other wood finishes. They give these products a pungent smell and can produce toxic polyurethane fumes that take long to dissipate.
Inhaling the fumes from a product high in VOCs can cause dizziness, lightheadedness, nausea, and a few other unpleasant symptoms.
The fumes can also trigger allergic reactions in people with allergies. This is why I prefer low-VOC kitchen cabinet clear coat and Bona Traffic HD has perhaps the lowest VOC levels.

Best Non-Yellowing Polyurethane Comparison Table
Why Does Polyurethane Turn Yellow?
Polyurethane yellowing is a natural phenomenon that is more common with oil-based polyurethane varieties. The process occurs due to exposure to the sun’s ultraviolet rays, polymer degradation, or oily deposits.
Exposure of these wood surfaces to the sun’s UV rays causes chemical reactions in the polyurethane coatings. These reactions lead to chemical changes in the topcoat, leading to a color change from clear to yellowish.
The chemical reactions responsible for the yellowing of polyurethane coatings happen naturally due to interaction with reactive particles like oxygen in the air.
However, UV radiation acts as a catalyst that accelerates these reactions and the subsequent yellowing. The longer the exposure to ultraviolet radiation, the deeper the color change.
Using wood species that are naturally yellow like pine also contributes to the yellowing. These wood species become yellower over time due to UV exposure.
The combination of yellowing wood and poly can make the color appear more pronounced. However, scuffing the polyurethane coating with fine-grit sandpaper should help lighten the color since the reactions happen from the top.
Type of Polyurethane that Won’t Yellow
High-quality water-based polyurethane is the only type that does not yellow. For instance, Minwax’s Polycrylic is non-yellowing and goes on clear, forming a durable coat on your project.
Additionally, water-based polyurethane is generally easy to use and dries pretty quickly—so you can apply multiple coats within a 24-hour window. The dry polyurethane coat will remain clear even after exposure to the elements over time.
Does water-based polyurethane yellow?
Water-borne poly generally does not yellow over time. However, lower-quality water-based polyurethanes form a noticeably amber tint as they age. They react more to the sun’s ultraviolet rays and other weather elements, forming a slightly yellow tint.
So it is always best to buy a high-quality water-based product if you want the coat to remain clear without forming a yellow tint over time.
Does Minwax polyurethane yellow
No, Minwax polyurethane does not yellow over time. It is among the best non-yellowing water-based polyurethanes on the market. It is easy to apply, dries quickly within a few hours, and allows you to apply multiple coats within a 24-hour period.
Is there a non-yellowing oil-based polyurethane
No, every oil-based polyurethane will eventually turn amber over time. The yellowing is due to UV exposure that causes and accelerates polymer degradation. Oily deposits are also responsible for the yellowing, which happens gradually with time.
When you use oil-based poly on hardwood floors, the coat will turn yellowish, giving the floor an amber tint. This color change often continues, making the coated wood darker and darker over time.
Does wipe on polyurethane yellow?
Yes, wipe-on poly is oil-based and therefore develops a yellowish tint over time. When used outdoors, prolonged sun exposure typically causes the clear coat to turn brown or yellowish. The absorbent qualities of the solvent can also cause the wipe on poly to turn yellowish.
How to Fix Yellowing Polyurethane
While most polyurethanes will yellow with time and continue to darken as time goes by, you can always fix the color and make it clearer. However, lightening a yellowing polyurethane coat requires a bit of patience and some elbow grease.
Additionally, the solution will depend on the nature of the color change. If the undercoat is affected, it may require slightly more work to lighten than when the coat yellows from the top. In any case, here is how to fix a yellowing polyurethane coat.
Method 1: Sanding the yellow topcoat
If the polyurethane color has darkened due to UV radiation, the chances are that it is only yellow from the outside. Sanding the outer layer will likely remove the yellowing and lighten the color.
So, use fine 220-grit sandpaper to scuff up the tinted coat of polyurethane. The chances are that you will not remove all the tint, but the sanding will lighten the color by removing the most affected part.
You don’t want to use coarse sandpaper of sand too deep because you do not want to remove the entire coat of polyurethane.
Method 2: Using mineral spirits
You can also remove much of the tint by scrubbing the surface with a soft sponge saturated with mineral spirits. This method is most suitable for oil-based polyurethane.
The mineral spirits will dissolve and remove the grease or oily deposits responsible for the yellowing color.
Method 3: Chemical stripper
When the color change results from the polyurethane sucking up the tinting stains from the wood beneath, sanding or scrubbing the top will likely not help. This is because the undercoat will be affected.
The best way to fix this issue is to strip down the polyurethane finish using a chemical paint stripper. Then apply a stain-blocking primer to seal the material before applying a fresh coat of non-yellowing sealant.
How to Keep Polyurethane from Yellowing?
The surest way to keep the finish from yellowing is to use a high-grade UV protective wood finish from the get-go.
Polyurethanes labeled as non-yellowing are usually formulated to resist UV radiation, hence keeping them from reacting and yellowing.
You may also reduce the UV rays entering your home by investing in UV-blocking window treatments or window films.
Best Non-Yellowing Clear Coat for Wood-Poly Alternatives
Aside from non-yellowing polyurethane, you could treat your wood with a clear coat for wood that won’t yellow to preserve its natural look. Here are the leading options to consider for your next project.
- Use to condition new or previously finished interior wood surfaces before staining
- Wax-free formula is compatible with all clear finish topcoats including oil-based polyurethanes
- Dries to the touch in 5-10 minutes and covers between 100-150 sq. ft. per quart
Shellac is often available in various shades. While it is not always entirely clear-colored, once you apply the finish, the color remains the same without tinting over time. So you can choose your preferred shade and be rest assured that it will remain the same.
Our editor’s choice of shellac is Rust-Oleum Zinsser 854 1-Quart Bulls Eye Sealcoat Universal Sanding Sealer.
It is high-coverage, with one gallon covering 400 to 600 square feet. This means great value for the money.
You will be happy to know that it is compatible with all clear wood finishes, so you can use it alongside any finish or primer that you prefer.
This shellac is formulated to suit all interior wood sealing projects, including floors. Perhaps its most outstanding quality is the lightning-fast drying that helps save you time. You can sand and recoat it in minutes and complete the entire project within hours.

What sealer will not yellow?
The best sealer that will not turn yellow is Minwax’s Polycrylic. It dries quickly within a few hours, is easy to apply, and can be recoated multiple times within a day. This sealer dries completely clear and stays that way without yellowing over time.
Does lacquer yellow?
Lacquer finishes typically do not yellow with age. They require very little maintenance and offer good protection against liquids and moisture damage. You need to use a sprayer instead of a brush, roller, or hand-rubbed cloth like varnishes and urethanes to apply them.
How long does it take polyurethane to yellow?
Polyurethanes typically take 3 years or longer to yellow. This happens as a result of the polyurethane pulling or absorbing oils, stains, and tannins from the wood, causing it to turn yellow. Poly will also react to UV rays and molecules like oxygen in the air, leading to a systematic color change.
Will polyurethane turn white vinyl yellow?
Polyurethane will not turn white vinyl yellow because poly is a clear coat and, as such, does not contain pigments responsible for changing the substrate color from white to yellow.
Does polycrylic yellow?
No, polycrylic is a water-based product, and so it does not yellow. Water-borne clear coats typically do not yellow over time, except for some cheap water-based products. But even these options only develop a slight tint.
Does varnish yellow?
Varnish does have a yellow tint and gives this tint to the wood it coats. The product is generally applied to raw wood furniture to bring out the wood grain and accentuate its mellow color.
Does polyurethane yellow over time?
Yes. Oil-based polyurethanes tend to turn yellow over time. This is usually a result of chemical reactions within the poly. UV radiation and oily deposits on the topcoat also cause it to turn yellow or amber over time.
Does urethane yellow?
Many types of urethane will yellow over time due to polymer degradation, oily deposits forming on the surface, and reaction with the sun’s UV rays.
Does minwax polycrylic yellow?
Water-borne Minwax Polycrylic does not yellow because of its water-based formula. Most water-based wood finishes remain clear without turning yellow over time as oil-based formulas do.
Does shellac yellow?
No, Shellac doesn’t yellow. Shellac’s natural UV resistance property allows the finish to retain its original hue for many years. This makes Shellac an ideal finish for furniture and other household items you want to keep looking new. Shellac is also highly resistant to scratches and other damage, so it can help to protect your belongings from everyday wear and tear. If you want a finish that will keep your home looking its best, shellac is a great option.
What is the best finish for cornhole boards
When finishing cornhole boards, a popular choice is a clear, water-based polyurethane. This type of finish offers excellent durability, protection against moisture and UV rays, and a glossy, transparent coating that enhances the natural beauty of the wood. It provides a long-lasting and resilient finish, ensuring that your cornhole boards stay in great condition for years.
Will water-based oil-modified polyurethane yellow?
Oil-modified polyurethanes tend to yellow only slightly because they are a mix of oil and water-based poly. For instance, Minwax water-based oil-modified polyurethane yellowing results from the chemical degradation of the oil-based poly in the mixture.
Final Thoughts on Clear Coats that Won’t Yellow
If you want a clear topcoat that will remain that way for the long haul, you need to use the best non yellowing polyurethane.
In such a case, high-quality water-based polyurethanes will be your best bet as their oil-based cousins tend to yellow significantly over time.
