Admixture for waterproof / tanking renders

Description

Ronafix admixture increases the physical properties of renders making them stronger and more durable than simple waterproofing additives.  Water permeability of Ronafix Mix A weatherproof render is extremely low, providing excellent resistance to frost, rain and entry of floodwater.  Ronafix Mix E tanking render will withstand water penetration by a 30m head of water; resistance to water vapour of a 12mm layer of Ronafix Mix A is 60 MN·s·g–1 50 times greater than the same thickness of sand/ cement and resistance of a 12mm layer of Ronafix Mix A is 60 MN·s·g–1 50 times greater than the same thickness of sand/ cement.  Flexural, tensile and compressive strengths are considerably better than unmodified render.   Typical shrinkage of Ronafix render mix designs is 0.01%, similar to that of epoxy resins.
