## Questions & Answers

**Q: Could you do several layers or one very thick layer to create a rubberized coating on something?**
A: Absolutely, just please remember that the thicker the final coating is, the longer the cure time will be. We highly advise creating the coating by adding layers to the surface rather than just one thick coat.

**Q: Any temperature requirement?**
A: Flex Paste can be applied in a wide range of temperatures from 0°F – 150ۜ°F. Once applied and fully cured it can withstand a wider range of temperatures from -40°F – 200°F.

**Q: Can this be used to fix crack in small ref/frezer**
A: Hi there. Thank you so much for reaching out. Flex Paste can withstand low temps like that in a freezer. Although some customers have found success with similar applications, it has not been tested for its safety when coming in contact with items used for food preparation, storing, or serving. Please contact us if you have any additional questions. We're always happy to help. Flex On!

**Q: can flex paste be painted ?**
A: Yes. Must be fully cured before painting.

Great coverage

### ⭐⭐⭐⭐⭐ Flex paste
*by F***D on 21 December 2020*

Super great stuff works really great for sealing up stuff ....a little on the pricey side tho

### ⭐ Does not work under water as stated! Does not seal up the best. Needs a better airtight method!
*by C***G on 4 May 2021*

Does not work under water as stated! Stays on putty knife and will not spread under water. Just globs and falls to bottom of pool! Great product for sealing around things. Was not sealed the best and had to waste quite a big ring of paste as they had not air sealed it the best. Also seemed to not be that full of a pail. Used it to patch the walls of my above ground pool around jet and skimmer. Plan on using to patch the liner inside in 2 places as well. Hopefully it does not harden before I can use the rest. I sealed it as shown and hope it does work.
