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

Typical Uses for the Elastomeric Polyurethane System

Epoxy.com System #495 Elastomeric Urethane Membrane System is ideal for:

  • Raised Walkways
  • Balconies
  • Concrete and Wooden Decks
  • Animal Housing and Cage Wash Areas
  • Coolers

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

Typical system components and application rates are as follows:

  1. Epoxy.com Product #899 Primer applied at a rate of 250-300 SF per gallon
  2. Epoxy.com Product #459 applied at a rate of 50 SF per gallon (1st coat)
  3. Epoxy.com Product #459 applied at a rate of 50 SF per gallon (2nd coat)
  4. Epoxy.com Product #77 broadcast into the wet send coat of Product #459 at a rate of 1/2 lb per square foot
