Krystol Mortar Admixture (KMA) is a specially designed chemical admixture for cementitious mortar. It contains a unique blend of specialty chemicals that react 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.

Key Benefits:

• Provides water resistance without requiring a surface applied sealer
• Reduces the overall cost
• Improves durability
• Improves resistance to cracking

Features:

• Contains proven Krystol technology
• Reduces water permeability
• Reduces water absorption
• Easy to use—simply added to the mix
• Improves workability—reduces water demand
• Reduces shrinkage and cracking
• Self-seals hairline cracks
• Resists weathering—a better alternative to liquid applied sealers
• Damp-proof mortar rendering on brick, block and other masonry walls
• Use to reduce permeability of plaster, stucco, and thin topping mixes

Rendering Mortar:

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

Other Applications:

• Protect masonry mortar
  – The mortar used between bricks and block when they are 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
• Trial batches are strongly recommended to assess the local plastic and hardened properties to determine appropriate mix designs.
