Snoop's Take

The Gardner-Gibson 9/30/6080 is a 4.75 gallon rubberized SBS roof coating designed to provide a strong, flexible, and waterproof seal for various roofing applications. This asphalt coating combines rubber and reinforcing fibers to aid in the sealing process, making it a popular choice for homeowners and contractors alike. Consumer feedback highlights both the strengths and weaknesses of this product. Many users appreciate its flexibility, with sentiments like "That flexibility helps with sealing" being a common praise. However, some concerns have been raised regarding its durability, as one user noted, "It'll bend when you walk on it and never look the same," indicating that it may not withstand heavy foot traffic. Overall, while the Gardner-Gibson roof coating is recommended for its effective sealing capabilities, potential buyers should be aware of its limitations in terms of durability under pressure. It may be best suited for applications where heavy foot traffic is not a concern.
