## Customer Reviews

### ⭐⭐⭐⭐⭐ Good product
*by  on Reviewed in the United States May 18, 2026*

This product works well. I used it to cover the tops of dock pilings. I recommend it.

### ⭐⭐⭐⭐⭐ Works as good as on TV
*by  on Reviewed in the United States May 18, 2026*

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.

### ⭐⭐⭐⭐ For the right job, it's the tool
*by  on Reviewed in the United States 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.
