Yes, Flex Paste can be effective in stopping water leaks. Its thick and malleable consistency makes it suitable for filling large gaps and cracks, ensuring that the seal created is water-tight. The product resists water and can be applied to metal, wood, and concrete surfaces.

What Should You Not Use Flex Seal On?
Even though Flex Seal can be used on many surfaces, some materials should not be treated with it.
Surfaces like exhaust pipes and engines that are constantly exposed to high temperatures or flames fall into this category.
Aside from this, Flex Seal should not be used on surfaces that are constantly submerged in water. These surfaces may not adhere properly to the sealant, causing damage or leaks.
In addition, Flex Seal should not be used on surfaces that are exposed to direct sunlight, as UV rays may degrade the sealant over time.
