FLEX SEAL White 396g Can | Available In Black, White Or Clear In 2 Sizes
Liquid Rubber in a Spray Can!
FLEX SEAL is liquid rubber in a spray can that sprays out as liquid and dries into a strong, watertight, flexible rubberised coating. Just a quick shot, and FLEX SEAL instantly seeps into cracks and holes, stopping the toughest leaks. FLEX SEAL can be used on a variety of surfaces including wood, metal, glass, tile and concrete. It can be applied on wet or dry surfaces and will last for years without cracking, peeling or losing any of its strength or sealing properties. And FLEX SEAL is unaffected by weather. In extreme heat or the cold FLEX SEAL will always keep its hold. FLEX SEAL is perfect for all your home repairs and once dry it can be painted any colour. FLEX SEAL is the easy way to coat, seal, protect and stop leaks fast.
Features
Q: How long does FLEX SEAL take to dry?
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 FLEX SEAL cover?
Depending on the number of coats and thickness, one 396gm can, can cover up to 12 sq. ft
Q: Can I apply FLEX SEAL on a wet surface?
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: Can I use FLEX SEAL to seal the inside of a water tank used for drinking?
No, we do not recommend that you use FLEX SEAL on surfaces where it comes in direct contact with drinking water.
Q: Is FLEX SEAL Clear the same formula as FLEX SEAL Black or White?
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.
