Also new from Versatile Building Products is Liquid Rock Self Leveler, designed for use as a self-leveling underlayment or wear-layer to create uniform, flat surfaces for subsequent floor coverings and decorative concrete treatments. The blend of portland cement, additives, aggregate and polymer doesn’t need curing and develops strength rapidly. Installations range from 3⁄16" to 11⁄2" in thickness in a single lift, and up to 3" with addition of appropriate aggregate. It is suited for use over pre-cast concrete, cast-in-place concrete, marble tile, ceramic tile, vinyl tile, terrazzo, wood and tile adhesives.
