Walmart Flex Seal Aerosol Liquid Rubber Sealant Coating, 14 oz, Clear $14.87 by CWEB Reviews

Flex Seal is actually liquid rubber in a can! It sprays out as a thick liquid, seeps into cracks and holes and dries to a watertight, flexible, rubberized coating. Flex Seal coats, seals, protects and will stop leaks fast! Available in 12 vibrant colors. It’s like a…Handyman in a can!


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.

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 60ºF. 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.
