40/ft² (3.72/m²) per Gallon @ 40.00 mils (1.0160 mm)
Dur-A-Fast Wearcoat is a polyurethane modified methyl methacrylate pigmented wear course coating to be used in conjunction with Dur-A-Fast Traffic Bearing Waterproofing Systems. Dur-A-Fast Waterproofing Systems are a series of rapid return to service, high performance, UV resistant decorative and functional traffic bearing waterproofing systems. Dur-A-Fast Wearcoat is a rapid curing, abrasion resistant, elastomeric coating which protects the surface and creates a tough, impermeable layer to protect the membrane, substrate or previous layers. It is designed to be ready to top coat within 45 minutes of application.
- Polyurethane modified Methyl Methacrylate based technology
- Extremely rapid curing, ready for topcoat within 45 minutes (depending on temperature).
- Cold curing capability, cures down to -20oC
- Outstanding water impermeability sealing properties
- Excellent water immersion properties
- High chemical resistance to acids, alkalis, salts, seawater, sewage and other compounds
- Fast curing properties
- Abrasion resistant, tough product
- UV Resistant
Dur-A-Fast Wearcoat is used as a wear coat for all Dur-A-Fast Traffic Bearing Waterproofing Systems to protect and add strength to the coating system for traffic bearing applications. Dur-A-Fast Wearcoat can be used in virtually all seasons, as it can be applied down to -20oC. Dur-A-Fast Wearcoat is also used for balcony terraces and pedestrian walkways, parking decks, mechanical rooms, plaza, pool, recreational decks, vehicular ramps and stadiums.
