KingProof PUW100®
One component, water based polyurethane liquid membrane for waterproofing and protection.
Overview
KingProof PUW100 is an environmentally friendly, one component, water based, modified polyurethane fluid, based on pure elastomeric hydrophobic resin. It produces a tough, rubber – like seamless finish with excellent surface adhesion to most types of substrates and excellent elasticity.
Applications
- Waterproofing and protection of:
- Exposed roofs, balconies and decks
- Wet areas, kitchens and bathrooms (under tiles)
- Basements and retaining walls
- Bridge platforms
- Internal and external applications
- For concrete, wood, metal, gypsum boards, etc
- Over bituminous waterproofing membranes
Advantages
- Free from solvents, tar, bitumen or any hazardous substance
- Low VOC content
- Excellent adhesion to almost any surface
- Excellent UV Resistance
- One component – ready to use
- High tensile strength and elongation
- Crack bridging capabilities
- Good chemical resistance
- The white colour reflects much of the solar energy reducing the internal temperature of the building
- STANDARDS Conforms to the requirements of LEED EQ Credit 4.2: Low - Emitting Materials: Paints & Coatings: VOC < 100 g/l
