HELP! New Gunite project has a "cold joint".

[PoolDoc]

You'd be better off posting on poolspaforum.com. There are a lot of pool guys there.

However, some caution -- the concrete pool guys I know aren't literate enough to enjoy participating in a forum. It's a pretty rough job. That may not hold true everywhere, but I think it's pretty common. So odds are you'll end up talking to someone who may know guys who shoot gunite, but who hasn't ever held a nozzle himself.

A better bet might be to ID another concrete guy in your area, and pay him to take a look.

Good luck!
