Krystol Mortar Admixture (KMA) is a hydrophilic crystalline admixture used to provide long-term protection of masonry mortars and concrete masonry units against water and waterborne contaminants by reducing permeability and absorption of the mortar.

KMA simplifies installation by removing the need for surface applied sealers and is easily incorporated into the existing mix-design and application processes. KMA provides superior waterproofing performance that lowers building maintenance and repair costs.
