Vermont Natural Coatings PolyWhey Floor Finish is a clear, water-based finish for bare or previously finished interior wood floors. It comes in Matte, Satin and Semi Gloss, in 8 oz samples, quarts, gallons and 5-gallon pails.
It's durable, quick drying and resistant to water and chemicals, and it won't yellow. It has a neutral odor, cleans up with soap and water, and can go over oil-based stain or finish. A gallon covers 500 to 600 sq ft. Each coat dries in 1 to 2 hours, so you can put down three coats in a day, and it reaches full cure in a week. It's a USDA Certified Biobased Product.
Stir it well and test it on a sample piece first. Apply with a brush, floor pad or T-bar at 65 to 80°F and 40 to 60% relative humidity. Sand lightly after the first coat with 220 grit or finer, then clean with water and Vermont Natural Coatings Wood Cleaner before the next coat. Don't use steel wool or a tack cloth.
Don't let it freeze. It's water-based, so in winter it can freeze on the way to you. Keep that in mind when you order in cold weather, and store it somewhere warm once it arrives.
Andrew Meyer founded Vermont Natural Coatings in 2004 in his hometown of Hardwick, Vermont. Its patented PolyWhey formula uses whey protein, a byproduct of cheesemaking, as a co-binder in place of some of the harsh chemicals in typical wood finishes.
