Use oil-based polyurethane for floors and other hard-wearing wood. Use Polycrylic where staying clear matters more, such as over pale wood, white paint or furniture. Minwax makes both, and its product pages draw the line plainly. Polycrylic “is not recommended for use on floors because it would require more frequent recoating in high-traffic areas.” Fast-Drying Polyurethane is listed for floors, and its sheens are sold as “Warm.” Polycrylic is described as “non-yellowing, non-ambering and low odor.”
“Polyurethane” is a family that includes water-based versions. “Polycrylic” is a Minwax brand name. The comparison below is between the two Minwax products.

Two label restrictions that catch people out
- Red mahogany stain: Minwax says Polycrylic “should not be applied over red mahogany stains” and points to Fast-Drying Polyurethane instead.
- Over oil-based stain: wait at least 24 hours after Minwax Wood Finish stain before applying Polycrylic.
Neither product is labeled for exterior use. Outdoor wood needs a finish rated for that exposure.
How to choose
- Floor, stair tread or tabletop that takes heavy wear: oil-based polyurethane. It is the floor-rated product of the two.
- White or light paint, maple, birch or a pickled finish where yellowing would show: Polycrylic.
- Fast turnaround or low odor: Polycrylic, given its 2-hour recoat, soap-and-water cleanup and low-odor label.
- Warm, deeper tone on oak, cherry or walnut: oil-based polyurethane.
Whichever you use, test the full stain-and-finish schedule on scrap first. Wood species and existing coatings change the result.
