Replaces Epoxy.com Product #409

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 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
