This self-leveling, self-sealing floor finish uses highly durable, internally cross-linked polymers blended to achieve a harder floor finish film. Unique chemistry results in a high-gloss, long-wearing finish that cures faster and harder than any other metal-interlock finish. Hard film formula requires less maintenance and resists dirt embedment. It is the perfect labor-saving advantage for Educational and Retail facilities that have little or no time for floor burnishing. Use Hard As Nails Hard Film Floor Finish on all types of resilient tile (vinyl composition, vinyl, linoleum) and properly sealed hard surfaces (marble, terrazzo). It dries clear and has a mild fragrance.
