Terrazzo 1000 is a thin-set epoxy terrazzo utilizing water-base epoxy. This system maintains the decorative and design benefits of standard thin-set epoxy terrazzo and eliminates the concerns associated with moisture problems from the concrete substrate. The water-based epoxy (3420) substitutes directly for the standard epoxy (3520) but is available only in an Off White color. Terrazzo 1000 is the ideal selection for on-grade applications where moisture vapor is a concern.
