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. 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 EPDM cleaner. The EPDM System provides
an alternative to high solvent products and can be used on both fully adhered and
mechanically attached EPDM systems.
Uses
EPDM Coating is a liquid-applied membrane used to resurface EPDM surfaces. 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
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

Note: Repair leaks promptly to avoid adverse effects, including
mold growth
