Krystol Mortar Admixture™ (KMA) (K-309)

Protection Admixture for Renders/Plasters, Masonry Mortars, and Concrete Masonry Units

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

When added to cementitious mortars or concrete masonry units, Krystol chemically reacts with water and unhydrated cement particles to form insoluble needle-shaped crystals that fill capillary pores and micro-cracks in the concrete and block the pathways for water and waterborne contaminants. Any moisture introduced over the lifespan of the concrete will initiate crystallisation, ensuring permanent waterproofing protection.
