Not what I was expecting. Was trying to patch cracks in my foundation but was only able to pour on holes at the base.
Weathers the storms
Would RecommendI bought this for weather/waterproofing and I keep buying it because it is easy to use and durable. I get the cheap chip brushes to put the Flex Seal on because cleaning brushes isn't the easiest with this stuff.

It Really Does Work
Would RecommendI have used this product in all of its forms. Spray, paint, putty, and tape. It's worked for everything I used it for. The wooden hand rails on my deck were starting to wear and splitter. Not anymore. It's also increased the griping. I just wish they would make it to color match.

Surprisingly easy!
Would RecommendI actually meant to buy a different flex seal product, it being a full liquid was a bit of a surprise, but it worked out great! I've been using it to patch holes with some wire mesh, and after letting it set it hardened and has held up well!

Seals well
Would RecommendVery pleased with this product. Sealed well. Easy to use.
Easy to paint on
Perfect to protect the garage wall where water could get in
Works okay
Does not do well on smooth surfaces. It peels right up. Make sure you paint on a rough surface.
