Crack in gunite spa - how to fix?

[huskyrider]

Go to your local pool supply and ask for two part "pool putty" epoxy.
Mix them equally and smush it into the crack.

Remember, "Smush" is the highly specific technical word!

Do try to feather the edges of the epoxy so there's nothing to grab on, especially when cleaning. And it's lots easier to use on dry surfaces, but it does work underwater. Almost all pool stores stock the stuff. It looks "poolish" in a pair of blue and white tubes.

As a quick note, a wet finger does an excellent job of smoothing and feathering, rewet finger as needed.

LMAO

I thought "smush" rather clearly described the application process!!! LOL

When using pool putty I don't really even try to feather the edges. I simply fill the void and try to wipe it back to the existing edge. I've never considered it to be a permanent fix. It's simply something I'll do as a courtesy on a service call to a customer who doesn't want to drop the coin on a legitimate repair. I'm not calling it a bad repair, rather it's a stop gap measure that could last anywhere from a year to four or five. It's also virtually impossible to blend with an existing pool finish even when the pool is white and your using white pool putty.
