WAXIE Diamond Guard RF Urethane Floor Finish The next advancement in urethane floor finish technology. It is a water based finish that is used on resilient hard floor surfaces such as VCT, linoleum, marmoleum, epoxy terrazzo and terrazzo flooring. The time, down-time, energy, money and risk associated with maintaining acrylic finishes is diminished. WAXIE Diamond Guard RF Urethane Floor Finish is a high performance, 3-part roll-on floor finish system with an extremely fast (4-hour) dry time. It levels immediately upon application and once it is applied, there is no need for a large number of coats or a buff/burnish to maintain gloss. It creates an extremely hard, non-porous, stain-resistant surface, and retains a glossy finish. In addition, it is extremely resistant to chemical extremes including betadine, hand sanitizers, and harsh chemicals that are frequently used to sanitize the floors. One kit can cover 350-400 square feet.
