Liquid RubberConcrete Foundation and Basement Sealant - Indoor & Outdoor Waterproof Coating, Easy to Apply, Black, 5 Gallon

Q: will this work on a pond?

Yes, as a matter of fact I just redid my riverbed and the pond with concrete and then applied a couple of good coats of the liquid rubber using the last coat to adhere the rocks and it is beautiful and is holding the water perfectly'

Q: What's the lowest temperature to apply this product ?

I don't think the temp affects the function of this product as it does not have a " Do not allow to freeze " requirement. It doesn't really dry as it remains pliable like rubber. I would however heed the suppliers advice and try not to apply it below 5c/40f if possible.

Q: Approximately how many square feet will one 5 gallon bucket cover?

100-125sq ft at a 60mil thickness. Bought 5, 5gal buckets to do 580sq ft of foundation and had about 1/2 gallon left over at an average of 60mil thickness.

Q: Question for anyone who sealed their basement from the inside. Has it held up against water leaks?

Yes so far... make sure you get every nook and cranny! I missed a tiny little hole and it leaked.
