Premium Epoxy Grout and Mortar with Color-Coated Quartz Kerapoxy CQ is an improved two-component, 100%-solids epoxy grout and mortar. Nonsagging/nonslumping in joints up to 3/8" (10 mm), water-cleanable and easy to apply, Kerapoxy CQ uses a proprietary aggregate to achieve its durable color, making it excellent for countertops, high-traffic areas, and areas needing stain and chemical resistance. Easy to maintain, Kerapoxy CQ will clean to the original color and contains BioBlock® technology to help protect against mold and mildew. Kerapoxy CQ is efflorescence-free and has excellent resistance to chemicals, staining, alkalinity, chlorine, bacteria, cracking and color deterioration. Because Kerapoxy CQ is impervious, this ensures that spills stay at the surface level for easier maintenance.
