How long does it take for Flex Shot take to cure?
While Flex Shot seals gaps and holes right away, full curing takes some time. The product typically forms a skin in about 20–30 minutes and cures within 24–48 hours, depending on temperature and humidity. For the strongest waterproof seal, apply it to a clean, dry surface and allow it to cure completely before heavy water exposure. Once cured, Flex Shot stays flexible and durable.
