Is Kerapoxy CQ worth it over regular grout?

For showers, kitchens and floors that see water and grease, yes. The epoxy resists stains and mold without sealing, which offsets the higher price and harder install.

How much area does a 1-gallon kit cover?

Coverage depends on tile size and joint width; a gallon typically handles a small bathroom or a modest floor. Check Mapei's coverage chart for your tile and joint dimensions before buying.

Can I use it with glass tile?

Yes, Mapei lists glass among the suitable tile types. Use a grout float gently and clean the surface before the epoxy cures.

How long do I have to work with it after mixing?

Pot life is short, so mix only what you can spread and clean within the working window. Small batches and a second person for cleanup help.

When is the price lowest?

Our take on the Kerapoxy CQ

Kerapoxy CQ is Mapei's two-component epoxy grout, sold as a 1 US gallon kit that mixes to a sanded, stain-resistant joint for ceramic, glass and stone tile. It resists water and mold and does not shrink, so it suits showers, kitchens and other wet areas where cement grout stains or cracks. The best new price is $65.00 at eBay as of November 4, 2026, with two stores listing it new.
