I had a horrible leak in my garage. I bought this in hopes it would save me the cost of a roof repair. It did. Works well, easy to apply with a roller brush. My S.I.L. applied a thin coat as directed on a warm day. I had no problems with it curing at all. I would recommend this product to everyone and if the problem comes up again on another area of my roof I will not hesitate to buy this product again for that fix as well. Review: Tough, Reliable sealant - If you want a sealant that can handle high water temperature and last the test of time, you found it. I used this to seal my homemade solar water heater tank back in early 2022. Today it still hasn't leaked although the tank has reached 130 degrees in summer. Four years of abuse and still reliable is a solid proof of its quality. ## Features - INDUSTRIAL STRENGTH BITUMEN FORMULA - Create a seamless waterproof membrane on flat roofs, metal roofs, low slope roofs, foundations, gutters, concrete surfaces, planter boxes, and more.

We are sealing our new concrete pond with this product = will not have fish in** A: New concrete needs to cure as per the installation instructions. Applying any of the Liquid Rubber products or most waterproofing products prior to a full cure may compromise the curing process of the concrete. **Q: I have a black plastic pond i got from home depot. will it adhere to that material?** A: Yes, put a few coats on. Let each coat dry well (24)hrs . You can spray on inside of pond. I used a undercoating product used for undercoating cars for the outside of pond. I put 3 coats on. I let each coat dry for 2 days before applying the next coat. All worked great my pond is like new and no leaks and all of my goldfish are fat and happy! Good luck! Take your time and cover every spot even sides. Make sure the pond is very clean before u start applications. I used a ruff kitchen pot scrubber to scrub clean. **Q: Does this project leave much of an odor after it has set?** A: Haven't smelled any odor. When putting it on there is a usual rubber smell like a basketball, but it doesn't seem to last very long. And it smells just like putting rubber on, which wasn't bad. It works for me. **Q: what color is it when it dries?** A: The product is brown when it is wet and black when it dries. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Easy to use *by M***N on May 3, 2026* I waited to post this review until it rained to give honest feed back.
