Review: Works as good as on TV - I used this to seal a leak in my concrete fountain. I was a bit hesitant having only seen it on TV commercials and no one else's experience. I cleaned around the crack, sprayed 2-3 layers over it and refilled. It's been several months and no leak.

### ⭐⭐⭐⭐⭐ Good product

### ⭐⭐⭐⭐⭐ Works as good as on TV

### ⭐⭐⭐⭐ For the right job, it's the tool
*by R***K on April 29, 2026*

Left no room for doubt that this is liquefied rubber in an aerosol. Be careful to get the Right Tool for the job. Check their "store" on Amazon- interesting discoveries there. For waterproofing / moisture barrier I would consider this again if a thin layer is adequate. May need to develop some application "technique" in some instances. My unusual situation involved some gaps that were worse than I anticipated. It's thin. Layering onto partially dry base layers to bulk it up did work but it's tricky until you find the way. I should have had silicone caulk on hand too but this seals hairline gaps nicely. With clear version, it's hard to see what's happening & to avoid waste or a running mess. Clogging is not a problem you'll likely have. As you might expect, liquid rubber involves intense solvents. You cannot over ventilate when using this. Plan ahead if using indoors.
