Liquid Rubber Waterproof Sealant - Multi-Surface Leak Repair Indoor and Outdoor Coating Water-based, Easy to Apply, Original Black, 1 Quart

Liquid Rubber Waterproof Sealant - Multi-Surface Leak Repair Indoor and Outdoor Coating Water-based, Easy to Apply, Original Black, 1 Quart

Q: How long does new concrete need to cure before applying liquid rubber? We are sealing our new concrete pond with this product = will not have fish in

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?

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?

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?

The product is brown when it is wet and black when it dries.
