KingProof C20®
Elastomeric acrylic cement modified waterproof coating.
Overview
KingProof C20 is a two component; elastomeric polymer modified cementitious waterproof coating suitable for internal and external applications. KingProof C20 provides a hardwearing, seamless, waterproof membrane for potable water retaining structures, tanks, basements, foundations and culverts. KingProof C20 shows excellent crack accommodation and is suitable for use on concrete.
Applications
- Waterproofing of water retaining structures and reservoirs
- Waterproofing of basements, roof, and foundations
- Waterproofing of bathrooms and wet areas
- Protection of concrete substrates and masonry against carbon dioxide, chloride ions, water and de-icing salts
Advantages
- Non-toxic, approved for use in contact with potable water
- Elastomeric, can accommodate static and dynamic cracks
- Fungus and mould resistant
- Able to withstand high positive and negative water pressures
- Excellent bond to porous and non-porous surfaces
- Breathable
- Durable, excellent protection against carbon dioxide, chloride ions and water
- Cost effective, quick and easy brush or spray
