worked for leak
Needed to seal leak along base of garage wall, worked well and no longer get water. It bonded to both wood and concrete, and we have since had a big storm and no water came through. I was honestly not expecting it to work, so I was very pleased. Was very thick, and a bit hard to apply, but I also have weak hands so not going to be too hard on it. Stronger people probably have less issues. It worked, and that is more important. Was a bit expensive, but it went a long ways. I will see how it lasts over time to give it my full approval, but if it holds up for a reasonable amount of time, I would use again.

dried product
I couldn't use the product because it was dry. It has good quality but be sure seller doesn’t send you old product. Otherwise, like me, you will throw it away without using it.
