Anti-Slip Stone is an invisible and long-lasting, water-based solution that increases the grip on treated floors when wet. Anti-Slip Stone does not alter the floor's appearance in any way yet still creates a permanent solution for slipping accidents. No matter if you have a floor made out of travertine, granite, marble, polished concrete, slate or terrazo, Anti-Slip Stone will create nano-sized pores (invisible to the human eye) which will get activated every time liquids touch them, creating non-slip surfaces and safer spaces! Test in a small inconspicuous area before applying on the entire surface to be treated.
