Elastomeric Roofing - TOPCOAT EPDM Coating

TOPCOAT® EPDM Coating



Description

TOPCOAT® EPDM Coating is a water-based, reflective, highly flexible, liquid-applied membrane designed to protect and provide reflectivity to EPDM and other single ply roofs. TOPCOAT® EPDM Coating is listed by the Cool Roof Rating CouncilSM for solar reflectance and thermal emittance. It is designed to be used after the roof has been treated with our proprietary TOPCOAT® EPDM cleaner. The TOPCOAT® EPDM System provides an alternative to high solvent products and can be used on both fully adhered and mechanically attached TOPCOAT® EPDM systems.


Uses

TOPCOAT® EPDM Coating is a liquid-applied membrane used to resurface TOPCOAT® EPDM surfaces. TOPCOAT® EPDM Coating is designed to protect and restore aged roof surfaces and to increase a roof’s reflectivity. It is to be used after the roof has been treated with our proprietary TOPCOAT® EPDM Cleaner. Substrate shall not pond water for a period longer than 48 hours. Surface must be free of ponding water, ice, snow, and debris prior to application. Do not apply at temperatures below 42°F. Substrate temperatures must be below 120°F when applying product.


Advantages
  • Highly reflective and listed by the Cool Roof Rating CouncilSM for solar reflectance and thermal emittance

  • Reflective white can dramatically decrease building temperatures

  • Advanced formulation that reduces the possibility of leaks at joints, edges, or corners

  • Flexible; will expand and contract with roof during temperature extremes

  • Helps to resist algae, mold, and mildew

  • Limited material warranty available for up to 10 years*

  • Available in 5-gallon pails, 55-gallon containers, and bulk totes
