Review: Excellent Product - Works as expected. I used it on an outdoor storage box. The water beads up upon contact with the wood now. Use this product in a well-ventilated area. The fumes are brutal. I used it outside, and the fumes still lingered. I used a 3M filter mask when applying it, but still smelled the fumes when I returned to the box to see if it was dry. And the box was outside while drying.
Review: Easy to apply and does the trick - Have purchased other flexseal products in the past, so was anxious to try this spray can which makes it much easier to apply than some of the other products and does a good job of ceiling. Any leaks that you have. I use mine on a corner for a gutter on the outside, and we live in a climate that can vary from 10° below 0 to 101° above.

## Questions & Answers

**Q: The grout throughout the rim area between the glass and the metal frame of my glass windows has deteriorated and leaks.  Will it seal this?**
A: Hello, thank you for reaching out! Many people have had success using https://www.amazon.com/dp/B00OX6OU5S to seal their grout.

**Q: I have a leak on my shower drain, would this work to seal the leak on PVC pipe?**
A: Yes many people have had great success sealing their pipes with Flex Seal.

**Q: Will flex seal work on concrete? I have a leak in my koi pond, would flex seal hold the leak while being underwater?**
A: Yes many people have had great success using Flex Seal on concrete.  We recommend using Flex Seal Liquid on your koi pond though since it is plant and animal safe.  Flex Seal in the aerosol can is not animal safe.

**Q: I have a couple of cracks in a  plastic pond shell.  Around 100 gallon pond.  Would this seal them?**
A: the tape might do the job--I sprayed on to a faux leather chair -- it's peeling off--I might get more  tape seal..
