Limitations to the Product

Application of Product

USE CHEMICAL-RESISTANT GLOVES, such as nitrile, when handling product.

Read entire label before using. SHAKE WELL before using. For new installations, Grout Colorant can be applied a minimum of 48 hours after grouting depending on jobsite conditions and ambient temperature. Grout joints must be clean, dry and free of existing sealers or coatings. Prepare existing grout joints:

MOST TILE & STONE: Use Aqua Mix® Grout Colorant Pre-Treat Cleaner or Aqua Mix® Phosphoric Acid Substitute.


EPOXY OR URETHANE GROUT JOINTS: Use Aqua Mix® Sealer & Coating Remover.

If more than 1 bottle of a single color is to be used, mix the material together in a large container to ensure uniformity of color. Spread evenly using the Applicator Brush or toothbrush, working Grout Colorant into joint using a back-and-forth motion. Thin, even coats should be applied, limiting the amount of Grout Colorant that gets on the tile. If going from a dark to light grout color, more than 1 application may be necessary with a minimum 2-hours drying time between coats. After Grout Colorant has dried 1 or more hours (never more than 12 hours), lightly mist surface with water and let stand 5 minutes. Remove excess Grout Colorant from surface of tile using water and a white nylon scrub pad. Ready for surface traffic in 2 hours. Keep area dry for at least 24 hours. Avoid direct scrubbing on grout joints for 20 days to allow a full cure.
