NuGrout Colorant and Sealer is part of a system that works together to provide long-lasting, professional-quality results. It is highly recommended that NuGrout Cleaner and Pretreat be used to properly clean and prepare grout surfaces prior to the application of NuGrout Colorant and Sealer.

Sealing of porous tile may be required prior to application to ensure colorant is not absorbed into the tile.

Use of NuGrout Cleaner and Pretreat may not be necessary when using colorant to correct or change the color of a brand new, unsealed grout installation. Test colorant on a small area for proper penetration and adherence prior to use.

Yes! NuGrout Cleaner and Pretreat is a concentrate, which can be diluted with water up to 100%, especially if surface to be cleaned is only slightly soiled. Always test strength on a small, inconspicuous area prior to use.

Yes! When properly applied, NuGrout Colorant seals the grout joint to resist the penetration of household stains, dirt and grime, so no additional grout sealer is needed. Proper maintenance and sanitation using household cleaners is still necessary. Avoid use of harsh chemicals and acids when cleaning.

When properly applied, NuGrout Colorant and Sealer inhibits the growth of surface mold and mildew. Proper maintenance and cleaning is still necessary because microbes can grow on other surface substances, such as soap scum, dirt and grime.

NuGrout Colorant is applied to the grout surface, then worked deeply into the grout using a good quality brush, such as the NuGrout Application Tool. Reference Application Instructions for more details.

If there is only light staining and a small difference in color change, you may only need one coat of NuGrout Colorant. For heavier-stained grout and/or a larger degree of color transformation, two or more coats may be necessary (waiting 2-4 hours drying time between coats). Test a small area prior to full application to determine your desired results.

NuGrout Colorant dries tack-free after 30 minutes and is ready for a second coat after 2-4 hours (depending upon climate conditions). The product is ready for light foot traffic after only 2-4 hours, normal foot traffic after 24 hours, and heavy, commercial traffic after only 72 hours. Allow up to 72 hours drying time for areas subjected to high humidity.

Yes! NuCaulk has a siliconized acrylic formula that can be used to seal around sinks, countertops, showers, tub surrounds, windows, trim, doors, siding, penetrations, hardboard, flashing and more! It can also be used for exterior applications.
