One FlexRock 5-Gal Kit Covers 150-250 Sq ft of flat smooth surfaces. We recommend a minimum of 32 mills of coverage. Sq. Ft/Kit 32 ml @ 250 ft.².
Flexible Rock Coating is super versatile it can be applied extra thick for added Roof Coating protection. By applying more than the minimum, you simply add more protection and extend the lifespan even further. This thicker system is perfect for filling cracks and imperfections. A chemical bond is formed between FlexRock and the roof, creating a waterproof casement.
*Coverage rates can vary depending on the type of roof substrate, surface condition, and application technique.
