DuraGuard 21 is a premium floor finish that quickly builds a deep, “wet look” gloss that lasts for weeks. It has been designed to be extremely durable in order to maintain its high gloss finish for an extended period of time. DuraGuard 21 will respond beautifully to conventional, high, or ultra-high speed floor equipment after weeks of wear and traffic when used with spray buff or mop-on restorer. The DuraGuard floor program meets all ASTM standards for slip, detergent, and soil resistance. Contains roughly 21% solids.
