Flex Seal

DIRECTIONS

Read entire can. Wear face and eye protection, protective gloves, and clothing. Make sure the surface is clean, dry, and free of grease, oil, and dirt. Shake well. Spray 8" to 12" from surface, using an even, sweeping motion. Apply multiple, even coats until ALL cracks and holes have been filled.

IMPORTANT: Allow 24 to 48 hours to dry before applying another coat.

Let it dry completely. (It usually takes up to 24 to 48 hours to fully cure.)

*Use Flex Seal ONLY in a well-ventilated area. When using inside, prevent vapour build-up by opening doors and windows. Ensure fresh air entry during application and drying.

*Do not use near heat, sparks, pilot lights or other sources of ignition.

FLEX TIPS:

Spray a larger area than area where the leak is and feather the edges. For best results, apply multiple coats rather than one thick coat and use at can temperatures above 16°C. Make sure Flex Seal has filled ALL cracks and holes and is FULLY CURED before testing product. If light can pass through, apply additional coats.

Q: What is Flex Seal Spray?

A: Flex Seal sprays out as a thick liquid, seeps into cracks and holes and dries to a watertight, flexible, rubberised coating that stops leaks fast. Once dry, can be painted any colour.

Q: In what temperatures can I apply it?

A: Flex Seal Spray is best applied to surface temperatures from -18°C to 38°C. Once fully cured, Flex Seal Spray can withstand temperatures from -29°C to 60°C.

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 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 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: 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: How much will one can of it cover?

A: Depending on the number of coats and thickness, one MAX can will cover up to 15 sq. ft., one 14 oz. can will cover up to 12 sq. ft. and one MINI 2 oz. can will cover up to 2 sq. ft.

Q: Can I use Flex Seal Spray on vinyl pools and pool liners?

A: No, we do not recommend the use of Flex Seal Spray on vinyl.
