Cannon Sports Ball Repair Sealant for Soccer, Basketball, Volleyball, & Playground Balls (Pint, 16 Ounces)

I purchased this product largely based on user reviews that indicated this product actually works as expected. I have not been disappointed and have repaired multiple balls saving our team many times the cost of this product in new balls.

I have used this ball sealant on six balls. Each of the balls is still holding all the air after several weeks. This is a great product that really works.

Worked on some balls and not on others. Maybe due to the size of the hole, Im not sure.

Bought this sealant for some volleyballs that would no longer hold air. 6 leaking from the valves and 1 with a small hole in the ball. This sealant worked like a charm. Injected this stuff with a syringe, filled the ball with air, bounced the ball as instructed and let it sit overnight to see if balls hold air, It worked, including the one with a small hole. I dont know how it works but I can tell you that it saved me from having to buy more balls. Great product

I worked on about a dozen balls, some still leaked after the process. Most of them leaked around the valve stem. I replaced the valves too but I still have some semi flat balls.

I bought some discount soccer balls, high end pro-quality at half price, turns out the bladders were leaky. So now how do I keep them from leaking? Enter Ball Sealant. The rubber sealant stays a viscous liquid inside the ball, 1 oz or so for each ball and bounce it aggressively. Seems to have plugged slow leaks on several soccer balls...I hope it is a permanent fix, it seems to work fine. The problem is finding an applicator and minimizing mess. Try Ball Doctor plastic applicator syringe with this. Balls stay bouncy and fully inflated, no leaks so far. Similar to Slime Tire Sealant or Ball Doctor.

Worked perfect first time. Still inflated after 1 months of practices

Saved a lot of balls for us.

I had purchased 14 Basketballs for my school on clearance from a membership wholesale club. They were $4 each, so even though some of them were not fully inflated I purchased them thinking they just needed inflation. It turned out that 6 did indeed have leaks to the point that they would not hold air overnight. The leaks were pin sized in random locations on the ball. I did research to find some way to fix these balls and could not find anything available locally, so I ordered this product through amazon. It was easy to use, and now the leaky balls have been holding air for 3 months without having to inflate them again. Also you can not tell that the liquid sealant is in the ball at all. Very worthwhile investment.

We put more in, but no luck. It just wouldnt seal the leak. I may try it on another ball, but dont expect much different.
