Review on 🦍 Extreme Hold: Gorilla Strength Construction Adhesive Cartridge - Unleash the Power! by Sean Young

As stated in the description: 100% waterproof - works underwater. Mine didn't work underwater. I lowered into the above-ground pool at least 4 inches above the level required to apply this product. After 2-3 days I applied the product. I left the country for 5 days. The next day I filled the pool up to the desired level. Later that day, on Sunday, the family bathed in it. A few days later I went to the pool to get some and noticed that the level in the pool had returned to the range I had sealed. I drained the pool about 2 inches below the area, let it dry a day, applied more product 3 days later, refilled the pool, family went swimming later in the day. Again a few days later the same conclusions, the pool emptied to this level. The sealed area is approximately 4 inches below the level. Damn! I wanted it to work. I use different types of Gorilla products. This is the first product I've had trouble sealing a crack in my rock/concrete pool with.
