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
- 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.
