FREQUENTLY ASKED QUESTIONS
A little over 25 years ago, a clever fellow by the name of Peter Roosen — an engineer who invented many game-changing technologies — developed this revolutionary product almost by accident! A strong believer in doing what is right, Peter experimented for months in order to prove that it was possible to achieve high performance without harming the planet. His amazing formula made of naturally occurring gypsum and renewable castor oil was named Ecodur — for its eco-friendliness and its durability.
Originally used as an architectural molding, Ecodur showed incredible potential as a protective coating and was used to coat the inside of oil tanks. Ecodur proved to be so strong, it was even used to protect acid frac tanks, water reservoirs, and highways. Now, it’s making waves as the roofing industry’s top sustainable commercial roof coating.

No! Ecodur Roof Coatings are made from castor oil and gypsum, making Ecodur VOC-free, BPA-free, and completely non-toxic. See our technology here on Dragon's Den!
Ecodur Roof Coatings adhere to the substrate at a molecular level, creating an inseparable bond. Other coatings such as epoxies, silicones, and acrylics rely on mechanical bonds, which require ideal surface conditions to adhere properly. Ecodur’s stronger adhesion means stronger roofs and stronger roof repairs (even for hard-to-coat roofs!). It can also be used with a variety of topcoats for aesthetics, cooling, and customization.
Ecodur is compatible with a wide variety of substrates, from acrylic and BUR to metal, TPO, EPDM, torch down, and more. See our Ecodur Roof Coatings page for a complete list of compatible substrates and links to case studies, videos, and more.
