To apply Flex Seal®, shake and spray from 12 to 14 inches away in a simple motion. Spray the affected area larger than the leak for complete coverage. Dry time depends on temperature, however it will usually dry within 2 to 3 hours at touch and complete cure in 24 hours. Flex Seal® gets stronger over time to make it last.
