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. Simplifying installation by removing the need for surface-applied sealers and easily incorporated into the existing mix-design and application processes, KMA provides superior waterproofing performance that lowers building maintenance and repair costs. When added to cementitious mortars or concrete masonry units, KMA chemically reacts with water and unhydrated cement particles to form insoluble needle-shaped crystals that fill capillary pores and microcracks in the concrete and block the pathways for water and waterborne contaminants. Any moisture introduced over the lifespan of the concrete will initiate crystallization, ensuring permanent waterproofing protection.
Longer board life, great workability and excellent bond! These are the primary advantages of SPEC MIX® Set Delayed Masonry Mortar. Masons working in hot-weather climates need a high-quality, specialized mortar to combat the negative effects associated with rapid evaporation of water from the mix, and SPEC MIX Set Delayed Mortar is the solution.
There is lots of talk about moisture management. Techniques vary between traditional stone masonry and that of modern construction, which uses various methods and materials to prevent moisture from migrating across the building envelope. But moisture management is only one piece of the puzzle in preserving masonry structures. Coatings and sealants are utilized on brick and natural stone in order to protect them from the elements or even graffiti artists. After careful assessment of the condition of the structure, coatings and sealants can be used for waterproofing, weather resistance or a glazed surface.
