Summary

Experts say Flex Seal is a spray sealant that can coat, seal, and protect various surfaces from water, air, and corrosion. It can be applied on wet or dry surfaces and can be painted over once cured. However, it may not work well on large or high-pressure leaks, metal or plastic surfaces, or extreme temperatures. It can be messy, smelly, and hard to remove. It may need multiple coats and touch-ups. It does not live up to the TV commercials, such as sealing a screen door on a boat.

John

Flex Seal is a cheap and easy way to fix minor leaks on plastic or other surfaces, according to experts. It is a liquid rubber spray that can seal cracks and holes with a waterproof coating. However, it is not a miracle product that can fix everything. It has a strong odor, does not work well on metal, and may peel off in hot weather. It also does not live up to the exaggerated claims on the infomercial, such as sealing a boat with a screen door. Flex Seal is a decent product for small repairs, but not a reliable solution for serious problems.

""

Flex Seal Rubberized Sealant Spray Coating is a liquid rubber product that can be used to seal cracks, holes, and leaks on various surfaces. It claims to be waterproof, flexible, and paintable, and to work on both wet and dry surfaces. However, it may not work as well as advertised, and it can be messy, smelly, and hard to remove. Some customers have reported that it did not stop their leaks, or that it peeled off or cracked over time. It may be useful for some minor repairs, but not for major or high-pressure leaks, or for surfaces that are exposed to extreme heat or cold. The instructions should be followed carefully, and multiple coats should be applied for best results.

Consumer Reports

Flex Seal is a spray sealant that can coat, seal, and protect various surfaces, according to experts. It can float a small boat with a screen bottom, but it has limitations. It may not seal large or vertical holes, it can tear under pressure, and it may need multiple coats and touch-ups.

Description

Flex Seal Liquid is actually liquid rubberized coating in a can. Similar to our Flex Seal Spray, but now you can brush it, roll it, dip it or pour it anywhere you need a watertight, flexible coating or sealant. Our patent pending, proprietary formulation starts out as a thick liquid and dries to a super strong and flexible, watertight, rubberized coating that protects and helps stop leaks fast. Color: Black.
