KingProof PUR150®
Spray-applied, two-component pure polyurea membrane for waterproofing and protection.
Overview
KingProof PUR150 is a sprayable, high-quality, two-component, 100%-solids, aromatic pure-polyurea coating that cures to form a solid, seamless, watertight and waterproof high-density polyurea membrane with high mechanical properties. It has excellent adhesion to many common construction surfaces – concrete, ceramic tiles, metals, aluminium, plywood and asphalt/bituminous sheets – when used with a suitable primer.
Applications
- Sloped and flat (walkable) roofs, balconies and overhangs, with a top coat for UV protection on exposed areas
- Under XPS insulation as part of an inverted or vegetative roof system
- Retaining walls and foundations
- Concrete/steel water-storage tanks
- Car-park and bridge decks
- Desalination and water-treatment plants
- Swimming pools, aquariums and lakes
- Green roofs and planters
Advantages
- Solvent-free
- Excellent mechanical properties – high tensile and tear strength, high abrasion resistance
- Excellent adhesion to all common substrates
- Fast application and fast curing/overcoating
- Strong, flexible, seamless and monolithic membrane
- Excellent thermal resistance – max service temperature 90°C, withstands short-duration up to 250°C
- Cold resistance down to -30°C
- Environmentally friendly, free from harmful VOC
