KingProof PUC100®
Cold-applied, two-component pure polyurea membrane for waterproofing and protection.
Overview
KingProof PUC100 is a two-component, high-solids, fast-curing, aromatic pure-polyurea coating that cures to form an elastomeric, watertight and waterproof polyurea membrane with high mechanical properties and strong adhesion to many types of surface. Its adaptability and drying time make it suitable for application on uneven surfaces and areas of any shape, whether curved or squared.
Applications
- Wet areas, bathrooms and kitchens
- Balconies and roof decks
- Under-tile applications
- Concrete structures
- Floors, parking lots and garages
- Over asphalt membranes and polyurethane insulation foams
- Light roofing of metal or fibre-cement
- Green roofs and planters
Advantages
- Excellent mechanical properties – high tensile and tear strength, high abrasion resistance
- Excellent adhesion to most common substrates
- Strong, flexible and hard-wearing membrane
- Cold-applied by roller, brush, trowel, squeegee or spray
- Excellent stability and durability; fast curing
- Environmentally friendly, low-VOC
- Good breathability, minimising humidity build-up under the coat
- Resistant to root penetration

Standards & Approvals
Usage & Packaging
KingProof PUC100 is available in 23 kg packs (component A: 21 kg; component B: 1.85 kg).
Apply in one or two coats with a minimum total consumption of 1.8 – 2.0 kg/m² to provide 1.5 mm total dry film thickness.
Store in unopened original packaging in cool, dry conditions, protected from frost and direct sunlight. At low temperatures store above 15°C before mixing, as low temperatures increase viscosity and can impair mixing and application. For specific storage advice, consult the KingKrete Technical Services Department.
