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.

Ecodur Roof Coatings are professional-grade products intended for trained applicators only. They have been applied by beginners successfully, but we generally recommend hiring a professional. As multicomponent products with a limited pot life, Ecodur Roof Coatings are not beginner-level products. Our warranties are not offered for self-install applications. We highly recommend you contact a Castagra Certified Applicator to handle your application.
