AquaTIGHT® GA (Grout Additive) is a grout, mortar, & concretestain-repellent additive. AquaTight GA by H2O Barrier Technologies is a new, unique grout additive for rendering grout, mortar, and concrete water repellent. AquaTight GA significantly reduces project time by eliminating the need for a follow-up visit to seal after installation. All AquaTight products work by selectively bonding to calcium, magnesium and aluminum ions present on the surfaces of these materials, creating a hydrophobic, mono-molecular layer that repels liquid water without impeding the flow of vapors. In other words, harmful liquid water cannot get in, but water vapor can flow freely throughout treated tile, brick, stone, concrete, and grout.
