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

A+

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

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..

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.

Dries clear and does the job

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.

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.

VERY GOOD BUT THE MAKER MUST NOT ASSUME THAT EVERY JOB IS OF MONUMENTAL PROPORTION! ! SOME KIND OF WAY TO CLOSE OF FOR NEXT JOB WOULD BE REALLY NICE LIKE a THREADED CAP ETC. I CUT a short Section of the CONE shape dispenser. AND LUCKILY I WAS ABLE TO SEAL IT BACK UP WITH A Q-TIP!! I only NEEDED 1/100 OR LESS OF THE SILICONE TO SEAL AROUND MY OUTDOOR SECURITY LIGHT!!
