OK, I have a leak in my Gunite IG pool, 16,000 gallons. It is at the main
Hayward skimmer where it butts against the cement at the rectangular water
inlet. This was sealed before with two part epoxy putty. It seems like this
stuff softens after a few years, and eventually raises up causing a leak.

So I proved the leak with red dye, and then chipped away the epoxy. That was a
lot of work. Then I filled it all in with ordinary plumbers putty. That stuff
does not stick very well, but for now seems to be holding. I do not think this
is a good long term fix.

I am wondering what is the right stuff to use here? Maybe silicon caulk made for
pools after I drain the pool about 3" so I can apply it? I am assuming this
stuff needs to be applied when the area to be sealed is clean and dry?

Thanks,
Jim
