Q: How long does it take to dry?
A: Dry time depends on the temperature, humidity and thickness of the coating. Flex Seal will usually dry to the touch within 2 to 3 hours and fully cure in 24 hours. It will get stronger over time.
Q: How much will one can of it cover?
A: Depending on number of coats and thickness, one large (10 oz.) can will cover up to 8 ft. and one jumbo (14 oz.) can will cover up to 12 ft.
Q: How much pressure will it withstand?
A: Flex Seal will withstand normal hydrostatic water pressure such as rainwater, but it is not made to withstand extreme pressure.
Q: Can I apply it on a wet surface?
A: Flex Seal can be applied on a wet surface, or moist environment in the event of an emergency. However, it will always adhere better to a clean, dry surface. To ensure its longevity, we recommend you reapply Flex Seal once the area is completely dry.
Q: How long will it last?
A: Depending on the environment, coats added, and maintenance, many people have found Flex Seal will last for years without cracking, peeling or losing any of its strength or sealing properties.
Q: Can I paint it on or brush it on instead of spraying?
A: Yes, you can spray the Flex Seal directly into a bowl and paint it, brush it or roll it on any area. However, we recommend using Flex Seal Liquid for these types of applications.
Q: Can I use it to seal the inside of a water tank used for drinking?
A: No, we do not recommend that you use Flex Seal on surfaces where it comes in direct contact with drinking water.
Q: Can I use it to fix radiators, tires or other areas with extreme heat and pressure?
A: No, Flex Seal is not made to withstand extreme heat or pressure.
Q: Can I use it on a gasoline tank?
A: No, Flex Seal should not be used to seal a gasoline tank, oil tank or any other flammable material.
Q: Is Flex Seal associated with GAF?
A: No, it is not affiliated with GAF and is not intended for use by Professional Roofers.
Q: Is Flex Seal Clear the same formula as Flex Seal Original and Brite?
A: In order to give Flex Seal Clear its amazing transparency, we had to make some adjustments to our formula. Therefore, the spray will be slightly thinner and multiple coats may be required to get the job done.
