Gardner Sta-Kool 770 5 Gal. Cool Roof Elastomeric Coating

Sta-Kool 770 Ultra White Elastomeric Roof Coating is a tough, highly flexible, rubberized roof coating. This high-performance, 7-year warranted elastomeric roof coating resists cracking and peeling. The coating also provides a highly protective barrier which reflects the sun’s heat and destructive UV rays. This helps to cool roof surfaces and reduce interior temperatures. This product is an “investment” which can actually pay for itself in savings on cooling costs. Covers approx 50-75 sq. ft. per Gal. depending on porosity of the surface.

Hi Bill. We wouldn't recommend coating the underlayment directly. Elastomeric coatings like Sta-Kool 770 are better suited for coating roof surfaces like cement tle (flat or barrel), metal roofs (aged galvanized), and aged roofs previously coated with asphalt, aluminum, or tar. Visit our web site www.gardner-gibson.com for more information about Sta-Kool 770 application as well as other tips and tools. You'll find a variety of information under the Resources tab. Thanks for your question!

Thanks for your question Ranger. For applications on RV Rubber roofs, we would recommend our Eterna-Kote Silicone Coating.

If you have a leak, it must first be repaired with a patching repair and reinforcement. The Sta-Kool 440 White Flash, is a thick flexible white patch that will seal cracks and stop leaks. After it is repaired, you can apply the Sta-Kool 770 Cool Roof Coating. Thanks for the question, and good luck with the project. We would love to hear how it turns our too!

Yes, thus product will bond to the existing clean deck. However, if it is a flat roof that collects water, consider our Eterna-Flex Silicone Coating as it is recommended with standing water. Thanks and good luck!
