Review: Exactly as pictured - Exactly as pictured
Review: Pretty ugly outcome for something so expensive - Despite trying to cover the whole crack with the epoxy, I still had micro-cracks I couldn't see and the foam came out, which stains the pebletec yellow. There are pits in the finish, because it's really hard to get the epoxy smooth on the inside. I might have been able to pay a pro to do a fix for not much more and it would have looked way better.

## Questions & Answers

**Q: Do you have a video for the application?**
A: I'm sorry we don't have a video at this time.  If you would like to provide your email, I can send you very detailed instructions on how this product works.  

Thank you for your valued business.

**Q: Can I order extra ports?**
A: I'm sorry we don't see extra ports on Ebay.

**Q: Do you have to plaster over top of this repair, or is this material water proof?**
A: I’m assuming the compound used to seal the crack prior to injecting the expandable foam is waterproof but I’m not certain.  Always best to check with the manufacturer.  I chipped it off after a few days and applied a bright white plaster to the repair.  Feather the edges with a damp brush to blend the patch.  I had a 5ft crack starting at the pool edge into my deep end.  It was 3/8” wide at the top to hairline at the bottom.  Haven’t had any leaks since.

**Q: Can this displace water from an actively leaking crack when water is infiltrating from ground water outside of the pool?**
A: Yes, because this product is hydrophobic (meaning that it activates with moisture).
