Bona Hardwood Floor Polish offers a protective formula that renews floors by filling in micro-scratches and scuffs, shielding against future wear and traffic, and adding a durable high gloss shine. For extra protection, the antimicrobial additive works to inhibit the growth of bacteria, mold and mildew while the coating is on the floor. Use every 2-4 months to keep floors revitalized and looking their best. Covers about 350 sq. feet.
