This ready-to-use, elastomeric product provides a seamless waterproof barrier and reduces crack transmission in tile and stone floor installations. One coat helps isolate subfloor movement up to 1/8" and two coats waterproofs. RedGard may be installed using a paint roller, trowel or airless sprayer. Designed for both interior and exterior substrates such as concrete, cement backerboards and exterior-grade plywood.
