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

This stuff works great

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

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

Use these to caulk my jets in my hot tub and so far it's holding, been about a month

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

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.

Pool& hot tub sealer

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.

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.

Resident to harsh chemicals and half the price as your local hot tub supplier
