Houzz

Grout Boost® additive mixes with cement-based grout in place of water when grout is installed to provide resistance to water and oil–based grout stains. For interior and exterior use.

  • Makes grout stain proof*. Repels dirt and resists stains.
  • Mixes in place of water with TEC portland cement based grout or any standard portland cement grout
  • Grout never needs sealing
  • Does not affect grout color**
  • Available in 48 oz plastic container and 27 oz and 70 oz containers at select Lowe's.

*Grout Boost is stain proof to most common household, residential stains when cleaned immediately.

**Grout Boost is mixed with a Portland cement based grout. All Portland cement based products, including grout, have the potential for efflorescence and color shading, which s not considered a manufacturing defect. Grout Boost doesn’t cause efflorescence. Refer to this blog post on how to prevent efflorescence.

Limitations
When using Grout Boost® stain resistant grout additive, grout doesn’t need to be sealed. If tile or stone needs to be sealed, do so before grouting, or consult groutboost.com for a list of approved sealers. Avoid applying sealer to tile/stone edges as this may prevent proper grout bond. If enhancing tile and/or grout, use a solvent-based enhancer. Do not use Grout Boost® additive with liquid, ready-to-use or epoxy grouts. Certain tile surfaces, including glazed ceramic tile, marble, stone and agglomerate tile can be scratched, stained or damaged when grouted with sanded/colored grout. Follow tile manufacturer/fabricator recommendations or test a small area prior to use to determine suitability. Not recommended for installations where chemical resistance is required. Never mix Grout Boost® additive with latex additive or any other additives.

Mixing Instructions for 48 oz. Containers
For the amount of Grout Boost® and allowable supplemental water to use, refer to the chart above.

Mixing Directions for 12.5 lb bag TEC® Skill Set™ DesignColor Grout and 2 Color Mix Cups:
Shake well before using. To start, pour approximately 3/4 of Grout Boost® additive needed into a clean mixing bucket. Stir in contents from 2 color mix jars into the Grout Boost using a paint stick or like tool. Stir for 10 seconds. Then slowly add the Grout Base to color mixed Grout Boost. Mix well. Continue to add in more Grout Boost® additive until the desired consistency is achieved. If all of the Grout Boost® product is used and additional liquid is still required to achieve the desired consistency, an additional 3 ounces of water may be added. Mixture should be easy to spread, but not pourable. Once desired consistency is achieved, mix well with drill on low speed (300 rpm) for a minimum of 2 minutes. Allow mixture to “slake” (sit in the container) for 10 minutes. Slaking allows the water, Portland cement and other ingredients to react properly. Remix for 1-2 minutes before using. The working time (pot life) when mixed this way is approximately 1-2 hours. If grout stiffens up during use, re-mix for 1 minute to return to normal consistency. Do not add additional liquid. To help ensure color consistency across the entire installation, use the same liquid to grout proportions when using multiple containers for the same job.

 

Mixing Directions for TEC® Skill Set™ Unsanded Grout, 10lb and 25lb Sizes:
Shake well before using. To start, pour approximately 3/4 of Grout Boost® additive needed into a clean mixing bucket. Then slowly add grout. Mix well. Continue to add in more Grout Boost® additive until the desired consistency is achieved. If all of the Grout Boost® is used and additional liquid is still required to achieve the desired consistency, refer to chart for supplementing with additional amounts of clean cool water if allowable. Mixture should be easy to spread, but not pourable. Once desired consistency is achieved, allow to sit in container for 10 minutes, then mix again. Install grout according to TEC Skill Set Unsanded Grout instructions. To help ensure color consistency across the entire installation, use the same liquid to grout proportions when using multiple containers for the same job.
