Dur-A-Comfort Membrane is a two-component, 100% solids, solvent-free, high solids elastomeric ergonomic polyurethane membrane formulated for use in Dur-A-Comfort ergonomic flooring systems. It adheres to concrete and wood surfaces to form a high build, ergonomic, sound-deadening membrane that gives comfort floors its unique properties. Dur-A-Comfort Membrane must be top coated with appropriate topcoat to achieve an effective Comfort flooring system.
- Outstanding water impermeability sealing properties
- Sound Deadening
- Zero VOCs, 100% solids urethane
- Possible LEED credits
- Softness underfoot
- High chemical resistance to acids, alkalis, salts, seawater, sewage and other compounds
- Fast-curing properties
- Excellent low temperature flexibility and crack-bridging properties
Dur-A-Comfort Membrane is an elastomeric, polyurethane-based ergonomic membrane that is used in conjunction with other Dur-A-Comfort topcoats to form a comprehensive, sound-deadening, ergonomic waterproof and seamless flooring system. It is designed to perform as a sound-deadening and ergonomic traffic-bearing membrane on a variety of surfaces such as concrete and wood. Capable of bridging cracks up to 1.6mm.
