What are the major differences between Polycrylic vs Polyurethane?
- Polycrylic is water based and doesn't off-gas as many volatile organic compounds as oil based polyurethane.
- Polyurethane is considered more durable than polycrylic.
- Polycrylic dries faster; however, you need more coats to achieve the same effect.
- Polyurethane has greater water resistance than polycrylic.
Can you apply polyurethane over polycrylic?
Yes, you can use oil-based polyurethane over polycrylic on a wood surface as it’s more resistant to damage, is a waterproof seal, and durable than other sealers. However, water-based polyurethane is also perfect. 4.
Is polyurethane better than polyester?
Polyester is +/- 96% solid content, polyurethane is between 50% to 65% solid content. Because polyester has a much higher solid content than polyurethane, polyester’s surface is stronger making it less vulnerable to scratching and chemical cleaning. However, polyurethane is more flexible than polyester making it suitable for applications where flexibility is important.

Polyurethane wood finishesPolyurethane wood finishes are synthetic coatings that are highly durable and water resistant, making them the best clear coat for wood protection.
Is Minwax Polycrylic protective finish waterproof?
It dries faster, as well. However, it's not as resistant to high temperatures or water. Polycrylic is a water-based product that is far less smelly and toxic than either type of polyurethane, making it easier to work with. It dries very quickly, although it can take a long time to fully cure for use.Feb 3, 2021
Is polycrylic scratch resistant?
It's ready for light handling after about three hours but needs at least 24 hours before it's ready for “normal use”. We need to be careful during this time because it can scratch or dent before it's fully cured. Polycrylic doesn't resist heat and moisture as well as oil-based polyurethane.Apr 7, 2020
How long does polycrylic last?
However, polycrylic is not as hard as polyurethane. This is because polycrylic has a very low level of paint chemicals and synthetic additives when compared to polyurethane. As such, the finish when dry is not as hard as polyurethane but is still hard enough to last over 10 years if applied correctly.Oct 25, 2021
Will polycrylic yellow over white paint?

What is Polycrylic?
A newer type of clear finish from Minwax called Polycrylic sounds like it might be a type of polyurethane, but it’s different enough that DIYers should know the advantages and disadvantages of each before choosing between the two.
What is the difference between oil based and water based polyurethane?
Oil-based polyurethane imparts a slight amber tone to the wood, so it’s probably not what you want over a pure-white painted finish. Water-based polyurethanes lack that amber cast, but some still do cause white or light-colored surfaces to yellow after drying or become slightly cloudy over darker finishes such as milk paint.
What is the best finish for wood?
Various oils and varnishes have been used to protect the wood for centuries. The most common clear finish is polyurethane, a tough polymer coating that’s durable, long-lasting, and easy to apply.
Does polycrylic paint smell?
It doesn’t smell as much as polyurethane, and best of all, it cleans up with soap and water.
Is polycrylic a durable material?
Polycrylic is not as durable as polyurethane and is meant to be used only on interior surfaces such as cabinets, furniture, and trim. It shouldn’t be used in exterior applications or on surfaces that are subject to lots of wear, such as floors, or that are exposed to water.
Is polycrylic a solvent?
Polycrylic has a water-based formula, so it’s more environmentally friendly—it cleans up easily with soap and water and its VOC (volatile organic compound) levels are much lower, so it doesn’t emit the noxious fumes of solvent-based finishes. (Manufacturers still recommend adequate ventilation when using any finish.)
Can polycrylic be used on mahogany?
Polycrylic, on the other hand, leaves a clear, non-yellowing surface, so it won’t change the appearance of lighter woods such as maple or birch, or anything painted white. Polycrylic is not recommended for use over dark-colored paints or red mahogany stain, however, where it’s clear appearance can become somewhat opaque or milky.
Uses
Polyurethane is water-soluble and works best on metal items like furniture or tools exposed to moisture over time. Polycrylic is an excellent choice for wood surfaces like decks or fences, especially if needed to withstand outdoor weather conditions such as rain.
Similarities
Both originate from polymers. Polymers are compounds that form when chemical bonds connect many identical repeating units. In the case of paint, these repeating units form a durable plastic film covering the surface without being absorbed into its pores. The thickness of this layer determines the quality, longevity, and price of the paint.
Differences
Polyurethane is created by reacting a liquid polymer with a catalyst called a urethane prepolymer, which causes it to expand and form a sticky resin mixture. Application is by brushing, and when it dries, it creates a stronger plastic coating than the original wood or metal.
Application
When applying either product to a project, use a primer first to help prep the surface. It helps ensure that the paint adheres better and lasts longer. After the primer is okay, apply either product and paint in the same manner.
What is Polyurethane?
Let’s start with polyurethane. This material is going to be available both in water and oil versions. Water-based poly urethane is a very mild solution.
