Default Will 5200 cure under water?

I have a vinyl lined, salt water swimming pool with a small 1/4 " hole in the wall about 2' below the water line. I was thinking of cutting a 1" square piece of left over vinyl liner and using 3M 5200 to "glue" it on over the hole. I just wonder if the 5200 will ever cure?

Yes, it will cure. Urethane is actually a moisture cured compound. I'm not sure how well it will stick to the pvc however. It may work or it may not. I don't think the 5200 reacts well to prolonged exposure to chlorine. It would be best to lower the water level below the hole and use the proper pvc cement.

Whether it will cure or not is only part of the equation. I doubt you'll get it to stick underwater.

If you want to use 5200, you'll have to drain it a bit.

Or, you could use the vinyl liner with an adhesive made for use underwater. Something like this: http://www.homedepot.com/p/Vinyl-Poo...2280/203796269
Just one I found. I have a concrete pool, so haven't tried this.

Yes, but try using life caulk instead, it will cure much faster.

Just curious, any way of putting a 3 sided plastic box around the area and bailing the water out of it to fix the hole instead of dumping all that water out of the pool and refilling?

Go to a pool supply shop and buy a vinyl repair kit. They're cheap and the included cement goes off underwater. Comes with a piece of vinyl material that you cut to size with scissors. Its a 5 minute job

This is what I use. I have a bunch of patches in my liner!

As mentioned they make kits to fix this. No need in reinventing the wheel

I have only owned concrete pools but it only takes a simple google search to find there are products specifically designed for that purpose.

Yes it will cure underwater.

You can buy vinyl patches that are like a sticker for a leak in your pool, just peel off the back and stick it on. I tried the one with the glue it did not work too well the peel and stick was great. I fixed a small leak in mine last year.

I wouldn't use 5200 for this. Awhile back I tried 5200 for a few things out of the realm of its intended purposes. I'm not crazy about the stuff and don't put nearly as much faith in it as a lot of members here do.
Just one application that failed miserably was caulking in a fiberglass whirlpool bathtub. It turned yellow and started failing in a matter of a few months.
It will cure when wet, moisture actually helps it cure, but again, I wouldn't use it here.

Thanks for the input. I bought a vinyl pool patch kit that seems to be holding so far. Time will tell.
