2-Pack Boss 802 Clear Pro Grade Silicone Sealant for Pool, spa, Household - 2 x 280ML. Tubes

I had a leak around my return box because the company who installed my new liner did not measure it correctly so they had to stretch the crap out of it to make it fit. I should have made them get a new one but it was a custom order and it takes three to four months to get another one by then summer would be over. So they came back to fix the leak and barely let the silicone set before they refilled the pool because they were in a hurry. Within three days it was leaking again. Anyway the point of my story is I applied the Boss 802 after cleaning the application area with denatured alcohol, and let it set for almost a week before filling the pool. Another plus was every day the sun was on it for at least four hours. Then I filled the pool it's been two months and no leaks so far. I mentioned all of this because i saw some negative reviews about the silicone not adhering underwater and was wondering if they properly cleaned and prepared the area before using the silicone? Anyway bottom line mine is holding tight will update at the end of summer when I draw the water back down for winter and visually inspect the silicone.

A+

In the Florida summer heat it starts setting up sooner than 15 to 20 minutes. I had to hurry with the install of my pool replacement skimmer. So far there are no leaks but will see how it holds up. I didn’t have time to clean the excess silicone on the skimmer face plate and had to cut it off with a utility knife the next day.

After reviewing silicones so many say waterproof but not intended to be under water and these showed to be able to be used under water and using to seal underound pool light and trims, not sure if works or will last but easy to work with and clear working good.

Way easier to Tool than some RV sealants around windows. Should last longer according to some videos I've watched.
