Grout Sealer #1 & Admixture is a water-based silicone polymer emulsion. It seals the grout to prevent staining and water intrusion. The sealer dries invisible and does not change the appearance of colored grout. Apply either with a “grout applicator” or paint onto the grout lines with a thin paintbrush. This provides the grout with an invisible protective barrier against water and oil-based stains. It also protects against household acids and alkalis, and the formation of mold and mildew growth all of which can cause discoloration and staining. The silicone polymer also makes the grout easier to clean. It is safe to use in enclosed spaces because it is water-based and non-flammable with negligible VOCs.
This product will cover approximately 300 sf/gal/app. We recommend two coats applied 2 hours apart rather than one thick coat. It should be re-applied every 2 to 3 years.
Grout Sealer #1 & Admixture is also a grout admixture. It replaces the recommended amount of water in the grout mixture (replace 1 gallon of water with 1 gallon of Grout Sealer). After curing the grout is completely sealed internally. This prevents water intrusion and staining throughout the whole structure so, in this process, it never has to be re-applied.
