ULTIMATE SLIP STOP Anti-Slip Tub & Tile Surface Treatment- is a new water-based micron engraving technology that when used increases the coefficient of friction on wet bathtubs, shower floors, ceramic and porcelain tiles, natural stone, and concrete. Apply anywhere there's a possibility of a slip fall accident. When wet, the treated surfaces will exceed ADA, ASTM, OSHA, and DIN slip fall safety codes in less than ten minutes greatly reducing the chance of slips/falls. ULTIMATE SLIP STOP is safe and easy to use with no visual surface changes and provides protection for children, adults, and senior citizens against dangerous falls.
