It combines all the consumer-friendly benefits of a PolyAcrylic Blend with the added protection of a UV stabilizer that helps prevent breakdown from sunlight exposure and protects underlying stains from fading. With its pure polyurethane durability, this topcoat is an excellent option for hardwood floors and other surfaces that require long-lasting protection and a semi-gloss finish.
