Ordering Notes:

  • Shipping leadtime: 3-5 business days.


EC-100 is a durable 100% acrylic elastomeric coating with 300% elongation. EC-100 is designed specifically for use over EPDM, new polyurethane foam roofing systems and for conventional roofs requiring superior adhesion and solar reflectance.

Custom Colors:

Standard in white, tan, gray. Custom colors available.

  • 12. Fire Rating: a. UL 790 Class A (NC), Class B (C-15/32).


  • Type of Resin: 100% Acrylic
  • Shelf Life: 1 year
  • Weight solids: 68%
  • Volume solids: 58%
  • Pigment Volume Concentrate: 43
  • Weight per Gal: 11.8 lbs
  • Viscosity CPS: 6500-8500


  • Superior resistance to ultraviolet degradation
  • Excellent adhesion to polyurethane foam
  • Low temperature flexibility down to -15F.
  • Low toxicity and odor, environmentally safe
  • Excellent dirt pickup resistance maintains high reflectivity which reduces substrate temperatures, prolonging roof life and reducing interior temperatures and energy costs.


Thoroughly clean off all dirt and debris. Seal around roof vents, pipes, repair cracks, breaks, and open seams.


Roll or spray evenly at a rate of 1 gallon per 100 Sq. Ft. This will achieve a mil thickness of approx. 9 MILS per layer. Total mil thickness is dependent on application (25 mils is typical RV application).


Apply only when not subjected to rain, high humidity or dew before curing. Acrylic base coatings must cure before being subjected to freezing (50 degrees F.) or moisture. Example of ideal conditions 4-6 hours above 70 degrees f. and low humidity.
