Mapei Kerapoxy CQ is a two-component, 100%-solids epoxy grout and mortar built for installations where standard cementitious grout won't cut it. It's the go-to for countertops, high-traffic commercial floors, kitchens, bathrooms, and any area that sees regular exposure to staining agents or harsh chemicals.
Unlike traditional grout, Kerapoxy CQ uses a proprietary color-coated quartz aggregate to achieve deep, durable color that holds up over time. The formula contains BioBlock technology to help protect against mold and mildew growth, and it cleans back to its original color with water — no sealer required, ever.
It's nonsagging and nonslumping in joints up to 3/8" (10 mm) wide, making it viable for both floor and wall applications without modification. Kerapoxy CQ does not contribute to efflorescence and resists chemicals, staining, alkalinity, chlorine, cracking, and color deterioration.
Ideal for residential and commercial tile installations including natural stone, porcelain, ceramic, wood-look plank tile, and glass tile in interior settings.

Can it be used on walls? Yes. The nonsagging/nonslumping formula works for both floor and wall applications.
Is it hard to apply? Epoxy grout requires a faster working pace than cement grout, but Kerapoxy CQ is specifically formulated for superior workability and cleans up with water during installation.
How many colors does it come in? Kerapoxy CQ is available in 40 colors.
Can I use it with natural stone? Yes for most natural stone. Note: it's not recommended for travertine or limestone. Always test in an inconspicuous area before grouting polished stone.
