Epoxy.com System #495
Elastomeric Urethane Pedestrian
Traffic Membrane
For Use Indoor, Outdoor and Direct Sunlight
Elastomeric Polyurethane System Description
Epoxy.com System #495 is an Elastomeric Urethane Membrane System, that is
liquid applied. System #495 Elastomeric Membrane System is seamless,
elastomeric (flexible), and UV. These qualities make it an excellent choice
for outside applications in direct sun and weather, where water tightness,
durability, and excellent appearance is required. Its elastomeric properties
will allow horizontal movements up to 1/8 inch without breaking.
Epoxy.com System #495 has excellent abrasion and chemical resistance.
The surface of System #495 can be varied to achieve the required anti-skid
and decorative look.
Elastomeric Polyurethane System Advantages
- Waterproof
- Elastomeric
- Resistant to Sunlight (UV)
- Safety (Anti-Skid)
- Epoxy.com System #495 is a system not just a single product so it
can be tailored to the specific needs of your application.
Elastomeric Polyurethane System Considerations
- All control joints must be properly installed, and carried
(revealed) to the surface of the system.
- Substrate must be properly prepared - see
Surface Preparation.
- Substrate temperature should be 60 degrees F. (absolute minimum of
55 degrees F required). If installation is to made at lower
temperature, the material will need a cold temperature cure.
- On grade or below grade applications must have an effective moisture
vapor barrier under the slab.
- When the substrate has hydrostatic and/or moisture vapor
transmission issues they must be treated before the installation of
Epoxy.com System #495 Elastomeric Urethane Membrane System.
- Not for use in California

Elastomeric Polyurethane Systems Maintenance
Clean with neutral soaps or detergents. Anti-skid floors typically use
periodic mechanical cleaning. Long period of heavy traffic may cause wear
patterns requiring a maintenance of the finish coat.
Elastomeric Polyurethane System Application
