Works as intended / order a back up just in case
Works as intended. One can may look like a lot, but once you actually put it in place your wish you ordered a second can or two or three just to be on the safe side and have a back up so that you don’t have to order and wait again.

It’s leaking and I bought 4 can and two was not spraying and I put in trash. How they sell this product for this high price. I want my money back. So bad not spraying and leaking those applied for the work.

Best stuff
This is the best on the market. I tried them all. It’s the most natural and the most sealing. I’ve used for several projects. Recently used as a patch. Dropped water cleaned, foamed, dropped flat rock on it. Perfect

Doesn’t work or missing
I’ve ordered 6 cans before and 2 didn’t work. This time I ordered 2 and only received 1! Aquascape has messed up my order many times with wrong or missing parts. And when you are building out of town and in the country it’s a big deal!
