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

Worked like magic! No leaks in our hot tub.

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

Has worked well up till this point and been a year

Quick shipping and packaged well, both tubes arrived on time and ready to use.

I have a pebble tech pool and a crack app area near the skimmer area and the ground became moist which meant it is.cracked all the way through the wall.. I got quotes as high as $3,000 to repair it, but I plan to resurface the entire pool in 2yrs, so that was not an option. I finally reached a pool repair guy that is widely known as the best. He understood my need to delay a full repair, so he recommended this sealant and told me how to install it like a pro. First drain the pool to an inch or more below the crack. I ran the backwash setting on my filter to pump it down. Let the area dry for 24 hrs. Apply the sealant very thickly and use a tool to force sealant deep into the frack. I used a pie serving knife. Also as you force the sealant in keep scraping the excess off the surface. Let dry 24 hrs and refill the pool. The repair guy said I may have to reseal when weather (temp) changes but it is good so far. I am pretty handy, but I recommend trying to do it yourself even if you are only modestly handy. If pumping the water kevel down intimidates you, just ask your pool slugs to do it while performing the weekly service. Also don’t worry about refilling as your water leveling system will automatically fill it. Finally, I didn’t wear gloves and did get a bit on my hands. However I found that I was able to peel or rub it off as it dried. Only sealant I will use outdoors and certainly in a pool.

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.

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, 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.
