Krystol Mortar Admixture™ (KMA™) is a specially designed chemical admixture for cementitious mortar. KMA contains a unique blend of specialty chemicals that react with the cementitious materials in the mortar to form hydration crystals. These long, hair-like crystals block the capillary pores and micro-cracks within the mortar so that permeability of the mortar is dramatically reduced.

How it Works

KMA is a dry powder added directly to the mortar during mixing. The crystals that form block the capillary pores and micro-cracks within the mortar, reducing the permeability and providing waterproof protection.

Where It's Used

Krystol Mortar Admixture can be used to damp-proof mortar rendering on brick, block and other masonry walls. It can reduce the permeability of plaster, stucco and thin topping mixes and waterproof shotcrete and concrete overlayments.
