The Aqua Mix Grout Colorant kit contains an Aqua Mix Pre-Treatment cleaner, an Aqua Mix Grout Colorant brush applicator and an 8oz bottle of Aqua Mix Grout colorant. After the tiles are scrubbed, the color is brushed on and left to (almost) dry. Then a nylon mesh pad is used to remove Grout colorant from surrounding tiles, leaving the lines a brighter white or an entirely new color.
Coverage: Approximately 50 to 300 sq. ft. (5 m2 to 28 m2) per 8-oz. bottle, depending on width and porosity of grout joint, size of tile and method of application.
