Surface preparation: Sand and prepare floor using NWFA industry standards. Vacuum and wipe surface clean prior to coating. Recommended applicators: T-bar, roller, or painters pad.


Stir and shake finish before applying. Pour a 2″ bead of finish near the starting wall. Use a dampened T-bar sleeve, roller sleeve or painters pad and pull the finish with the grain of the wood. Maintain a wet edge at all times. Feather out all turns. Avoid moving too quickly and maintain steady, medium pressure to avoid applicator drips. Allow the first coat to dry 2 hours. High humidity and/or low temperature conditions may increase dry time. For best results, apply in temperatures between 65°F-80°F with a relative humidity of 40%-60%. Up to 4 oz. of water per gallon may be added for variable application conditions. Between coats: For best results, abrade after each finish application with a fine 220 grit paper. For PolyWhey 3500, abrade if 24 hours have passed since the previous coat was applied. Always vacuum and tack thoroughly with a clean, damp cloth.

Covers approximately 600-700 square feet per gallon
