## Questions & Answers

**Q: bathtub**
A: You need two of them, an outside meadow, a sunset, and some ED medication.   Not sure how you'd use this putty so I won't ask.

**Q: does it work to fix pool leaks?**
A: I bought this as a last ditch effort to fix my pool. The one i already had to replace 2 pump motors and a whole pump assembly on. It was a $200 pop up intex pool from Wal-Mart. I had to patch it once this season but did so with it empty and used a pool patch kit and a crap ton of gorilla tape as insurance. So imagine my horror when i went to shock the "dark green pool" (as the kids described) that the kids won't leave the pump plugged into and see it low. 

Find it leaking and get out that handy gorilla tape. Wasted a whole freaking roll. Still leaking. Its 195 billion degrees in the Midwest and the kids won't leave my doors shut so the pool was how to cool down.

I grabbed this stuff and played with the putty on the way home (per instructions you gotta work with it first) went and shoved a bit into the hole. Fail. Added more.... Somewhat stopped. Still leaking. So i shoved about the size of a quarter into that small hole... Tons on top....

30 minutes later.... Success. For now at least.

Now to see if it withstands more water pressure and a bottle of chlorine for the green pool. Wonder if this will work to keep the power plugs together and running so the kids can't torn off the pump again.

This works beyond great.... Just don't skimp on the amount. The pool is hitting the trash this year.... So i won't know if this works long term... Im just looking for another 7 weeks.

**Q: Will it stick to something already wet?**
A: Yes. I used it to seal a gap between the plastic of my pool skimmer and the grout and tile of my pool lining--all underwater. It worked great and is still working many months later.

**Q: I have leaking pvc that is wet. Will this work on the wet pipe joint?**
A: Yes, it should. Make sure you cut section off with the outer & inner layer of JB Weld & thoroughly blend it together with finger tips.
Rough up entire surface you plan on applying epoxy to with sand cloth/paper so it can adhere to material which it is being applied to. If it spraying water under pressure, you need to turn water off otherwise it will travel under neath putty and escape. Turn water off, clean and sand area, apply putty wait a good hour feel putty should be nice and hard, if so turn water back on. This stuff is amazing, I have used it on 8"-10" PVC leaks at fittings but not under ant type of pressure, it was for a greenhouse cooling system,  I have used it on my bath tub to seal a 1" hole my son punctured with toy in tub. I have used it on natural gas, galvanized pipe to plug hole in pipe. Prep the area clean and sand most important,  doesn't take much putty. My bath tub I did two applications, did first let cure then sand the cured putty and just onto fiberglass of tub again to Rough up give putty something to bond to. I wait a good hour before I test. It's holding like a full on CHAMP from a good 5 years ago. It's good strong stuff, I recommend strongly to my fellow plumbers!
