Mapei Flexcolor CQ Professional Grade 7.56 L #93 Warm Gray

Flexcolor CQ Professional Grade in Warm Gray is a ready-to-use grout with colour-coated quartz. On paper that is ANSI A118.19. It fills joints from 1/16" to 1/2" and needs no mixing. It cures by water evaporating out, not by a cement reaction. A 7.56 L pail does about 416 sq ft over 12" x 12" tile with a 1/8" joint. There is no pot life to race. Start cleaning up 5 to 10 minutes after spreading, once the surface skins over. Light foot traffic at 24 hours, normal traffic at 2 days, heavy commercial at 6 to 7 days. Three days before it sees water, shower use included. No sealer, ever. That is the main reason people choose it. Not submerged, so no pools or hot tubs. Not in steam rooms or saunas. Not on pebble, river rock or irregular tile. Not in joints 1/2" or wider or deeper. Not on commercial kitchen floors or anywhere no-rinse enzymatic cleaners are used. Not under repeated steam cleaning or power washing. It is stain resistant, will not mark the tile beside it once dry, and does not contribute to efflorescence. Test it against glass mosaic and marble before you commit. Both the Mississauga and Barrie stores carry it.
