No more time-consuming & costly tear-offs

With Ecodur Roof Coating, you can stop further damage to a flat roof without reroofing. Ecodur’s extreme adhesion and durability means it can usually be applied directly over hard-to-coat substrates such as embedded gravel, without the need for spudding or complete tear-off — saving you time and labor!

Unparalleled performance

    Ecodur is the flat roof coating of choice for longevity, waterproofing, and heat deterrence. Over the past three decades, more than 10,000 tests have been performed to prove and improve Ecodur’s performance, including:

  • Waterproof testing

Easy and safe to apply!

Ecodur Roof Coating is, if we may be so bold as to say, a contractor’s dream. Applied quickly and easily by brush, roller, or squeegee — without any chemicals, odors, or off-gases — Ecodur self-levels during its remarkably fast curing time to create a smooth surface that is completely nontoxic. It’s so safe, in fact, that Ecodur even has an ANSI/NSF-61 certification (it can be used in contact with drinking water and food).

100% sustainable

While most coatings are either good performers or good for the environment, Ecodur Roof Coating was specifically developed to combine maximum performance with safety. You can even tell by its name: “Ecodur” stands for “eco-friendly” and “durability,” so you’ll always remember its promise to be high performing without harming the planet.

Made with natural ingredients — its two core ingredients being renewable castor oil and recyclable, naturally occurring gypsum — Ecodur has:

1

Zero VOCs

2

Zero BPA

3

Zero toxicity

4

Zero measurable effects of saltwater submersion

5

Broad spectrum resistance to pollution and chemicals
