How long does it take Flex Seal Spray to dry?

Dry time can vary depending on temperature, humidity, and thickness of the application, but Flex Seal Spray usually dries to the touch in about 2-3 hours and fully cures in 24 hours. We recommend spraying Flex Seal about 8-12 inches from the surface and applying multiple thin, even coats, allowing each coat to dry before applying the next.
