Would RecommendThe seal worked great to create a seal around a vertical access pipe (PVC pipe) on top of a concrete septic tank vault. The paste was easy to work with and cured within 24 hours, ready for backfill.

One of the cartridges flex paste what is dried out
Would RecommendI bought a couple cartridges of flex paste. Generally it worked well but one cartridge was dried out so much that I broke my caulking gun trying to get it to come out.

Seems like the seal did not seal very well,or the product sat around too long. Also I sure wish the paste was a little softer and easier to spread and work with.
