Low-Odor Water-Based Polyurethane for Hardwood Floors
Vermont Natural Coatings PolyWhey® Floor Finish is a professional-grade, water-based polyurethane for refinishing hardwood floors without the strong fumes of an oil-based poly. It is a great choice when the family is still living in the house during the project, and contractors appreciate the fast turnaround: with 1–2 hour dry times, up to three coats can go down in a single day.
The formula is built on patented PolyWhey® technology, which uses whey protein from Vermont's dairy industry to create a tough, clear finish. It is a USDA Certified Biobased Product, carries a low VOC rating (176 g/L), and cleans up with soap and water.
Key Benefits
- Clear, non-ambering finish – keeps maple, oak and light woods looking natural instead of turning yellow over time.
- Durable & chemical resistant – stands up to foot traffic, spills and routine cleaning.
- Fast recoat – 1–2 hours between coats, so floors are back in service sooner.
- Lower odor – a neutral smell compared to solvent-based floor poly.
- Covers 500–600 sq. ft. per gallon per coat.
- Works over oil-based stain once the stain is fully cured.
Ideal For
- Homeowners refinishing floors in an occupied home
- Families sensitive to strong finish odors
- Flooring contractors who need a quick turnaround
- Schools, offices and other commercial interiors
- Light-colored woods where a natural, non-yellow look matters
Sheen
This quart is the Matte sheen, a flat, low-reflection finish that gives floors a natural, unfinished-wood appearance while still providing full polyurethane protection. A quart is perfect for small rooms, stair treads, touch-ups and testing.

Application Tips
Sand the floor and remove all dust before finishing. If you are staining first, let an oil-based stain cure completely before applying PolyWhey. Stir well (do not shake) and apply thin, even coats with a quality applicator such as a T-bar or synthetic pad, maintaining a wet edge. Provide good ventilation during application and drying, and treat the floor gently with light use until the finish fully cures in about a week.
Frequently Asked Questions
Does PolyWhey Floor Finish have a strong smell?
No. It has a neutral, low-odor profile compared to oil-based floor polyurethane, although normal ventilation is still recommended.
How long does it take to dry?
Coats are usually ready to recoat in 1–2 hours. The finish reaches full cure in about one week.
Will it turn yellow?
PolyWhey dries clear and is designed to resist the ambering that oil-based polyurethanes develop over time.
Can I put it over an oil-based stain?
Yes, as long as the stain has fully cured before you apply the finish.
