Why did you pick this product vs others?:Quick fix for leak in my hot tub. Holds up great 1 year later.

Dries clear and does the job

I received this item and open the box a few days later and plunger had come out and turn sideways on one of the silicone tubes and caused half the tube to dry out. I still used it because I couldn't wait to complete the project had a deadline..

Used this for my pool. The plaster on the tiles along the pool top edge (below water line) was cracking and crumbling off slowly. I used this silicone sealant to seal it up so water doesn't get behind it and make more tiles loose. Eventually will need to get a pool resurfacing, but this is a temporarily measure to prevent it from getting worse. It's been about 6 months and still holding well.

A+

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.

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.

Nothing extraordinary here except for the price. Good stuff but no different than any other name brand 100 % silicone
