KingProof C75M®
Two-component, polymer-modified, flexible cementitious waterproofing and protective slurry mortar.
Overview
KingProof C75M is a two-component, polymer-modified cementitious waterproofing and protective slurry mortar for concrete. It is slightly flexible, allowing it to tolerate fine cracks, and is suitable for both interior and exterior applications. It can be mixed to a slurry or a trowelable consistency and is available in concrete grey and off-white.
Applications
- Improving the watertightness of water tanks, reservoirs and clearwells
- Waterproofing of potable-water tanks, reservoirs and clearwells
- Internal and external waterproofing and damp-proofing of concrete, mortar, blockwork and brickwork
- Protection of concrete against de-icing salts and freeze/thaw cycles
- Sealing of hairline cracks in concrete not subject to movement
- Interior and exterior waterproofing of basements
- Horizontal surfaces subject to light foot traffic, such as balconies
Advantages
- Improves the watertightness of water-containing concrete structures
- Protects against water penetration while remaining vapour permeable (breathable)
- Excellent freeze/thaw resistance
- Good adhesion to sound, prepared substrates
- Easy and fast mixing and application
- Good abrasion resistance
- Protects against concrete carbonation – a 2 mm coating is equivalent to approximately 150 mm of concrete
- Can be mixed to a slurry or a trowelable consistency
- Suitable for contact with potable water
