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

Used to re-seal some jets on my hot tub. Worked like a charm for that job... wish I'd have found this stuff sooner.

Great product to seal things in my hot tub and shower. Also great value.

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.

This stuff works great

we had an 8-foot-long crack in our pebble tech pool about 4 ft deep. I drained the pool and let it dry for several days, applied the sealer to the crack and let the sealer sed for about 3 days. After refilling the pool, the leak has stopped.

A+

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.

Great, but one of 6 tubes arrived damaged and was solid when I tried to use it. Check on arrival!!!

Very effective at sealing unused hot tub ports.

Super happy with boss silicones work better than anything else on the market.

For the jets I couldn’t access, I sealed them from the outside only and after 2 months, no leaks. Time will tell. I used 1.5 tubes to do about 15 jets with a thick application. Also let product cure for 24 hrs before filling tub.

Ended up returning this but I can tell you that the customer service from the seller is outstanding. I definitely would order from this vendor just for the customer service but I did do a lot of research on the product and it is super good for hot tubs and pool repairs.
