KMA is an admixture for cementitious mortar. It contains Kryton’s unique Krystol® technology that reacts with the cementitious materials in the mortar to form hydration crystals. These needle-like crystals block the capillary pores and micro-cracks within the mortar to dramatically reduce permeability and water absorption of mortar rendering over brick, block and other masonry walls.

8. Krystol Mortar Admixture (KMATM) Chemical admixture for cementitious mortar Specialty chemicals that react with cementitious materials in mortar to form hydration crystals Needle-like crystals dramatically reduce permeability & water absorption of mortar rendering over brick, block and other masonry walls

9. Key Benefits of KMA™ Provides water resistance without requiring a surface applied sealer Reduces overall cost Improves adhesion Improves durability Improves resistance to cracking

10. Typical Applications of KMA™ Damp-proof mortar rendering on brick, block and other masonry walls Reduce permeability of plaster, stucco, and thin topping mixes

11. Rendering Mortar A render is a mortar generally made up of cement, fine aggregate, water, and sometimes lime or a plasticizer Applied to the face of a brick or block wall surface, usually in two or more coats, to form the finish of the wall

12. Other Applications for KMA™ Protect masonry mortar Mortar between bricks & block assembled into a wall Reduce permeability of concrete bricks and blocks when they are manufactured Most beneficial when used in brick and block walls that will not be covered by a render

14. Application of KMA™Application Instruction 110

15. KMA™Application: Surface Prep Surface must be clean and free of dirt, oil, or loose debris Strongly recommended that the surfaces be “saturated” with clean water prior to applying rendering to achieve improved performance in adhesion, durability and reduced cracking

16. KMA™Application: Mixing KMA is a dry powder that is added directly to the mortar during mixing Dose KMA at 2% by weight of cement—1 kg KMA per 50 kg cement. Most KMA mixes will require less water than usual

17. KMA™Application: Mixing Can be added at any time during the batching process plastic properties may vary with the time of addition depending on the mix proportions and site conditions. Adjust the mixing sequence as necessary to optimize the mix for your application. Allow KMA to thoroughly mix at medium/high speed for a minimum of 2 minutes or until the admixture is fully incorporated

18. KMA™Application: Install Mortar Install mortar as normal. For increased damp-proofing performance apply mortar up to 5 cm in 2 or more layers (see ASTM C926). Continue occasional mixing as the material is being installed. Discard any material that shows signs of stiffening or setting—do not wet-up by adding water.

19. KMA™Application: Curing Proper curing is essential to achieve the performance and benefits Wet curing with a fog mist spray, sprinkler or wet burlap for 3 to 7 days is recommended. Protect fresh applications from wind and direct sunlight.
