Grout Sealer 1


Aqua Mix Grout Colorant is an easy-to-use waterborne epoxy that recolours, seals and rejuvenates existing grout joints. Formulated to provide maximum stain protection. Change the appearance and colour of your faded, stained or patchy grout with 20 colours to choose from. Also simplifies ongoing grout cleaning.


For use on:

Sanded, unsanded and epoxy grout joints. Effective for interior and exterior applications. Suitable for new or existing grout


General Surface Prep:

Test a small area according to application instructions, with a minimum 1-hour cure time to determine desired results.

The Grout must be dry prior to applying Grout Colorant – the following document explains in detail the definition of the term “dry” as it relates to Colorant application. READ MORE

Application Method:

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:

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.

Drying Time:

  • 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.

Cleaning of equipment:

Clean tools with water and soap before material dries
