Works great when used as directed.
Does a good job sealing small cracks in my concrete pond.
I used the White and Clear, that is enough for me to recommend the Brown.
The spray is fine, coats in a good pattern, does not splatter spray.
But this has a flow quality that allows the spray to concentrate on the area of the leak, enter it until it clogs the leak then backs out to where you are spraying.
I have used the product before, and it seals small leaks in hard to reach places.
I've used this product to seal leaking nail holes and small cracks on walls and roofs.
IT did not stick to another product that we used to seal and it took a several layers to seal.
DO NOT use anywhere near silicone.
It ate away the sealant I already had in place.
