Flex Seal Flex Seal Editorial Review

Flex Seal MAX Liquid Rubber Sealant Coating, 2.5 Gallon, Black is designed for both indoor and outdoor use, delivering robust sealing properties thanks to its liquid rubber formulation. Users have noted its effectiveness, particularly when preparing surfaces according to manufacturer guidelines, with a temperature range of -80° to 350°F making it versatile for various applications. However, some reviews point out challenges in application due to thickness and the initial strong odor that dissipates over time. While it is praised for its sealing capabilities, a few users found it difficult to roll on and experienced peeling issues, indicating that it may be better suited for patchwork rather than extensive covering.
