Rated 3.0 out of 5.0 by gzuckier Not quite what i was looking for.
My idea, such as it was, is to fill the cracks in my driveway with the expanding foam before topping. Tried it with the usual Great Stuff a few years ago, works better than the stuff sold to fill cracks. But it's yellow, so needs a good coat of blacktop to cover it, and when a piece breaks off the yellow is back, so I discovered this stuff which is black.
So it behaves like the usual Great Stuff, color is kind of a very dark eggplant/brownish.
But the problem is that after a couple of days of sunlight, it's faded to a slightly greenish version of the same yellow.
So, unless you need black foam indoors, I guess, there's not a lot of reason to use this rather than the normal colors
Didn't try it underwater to see if it holds color better then.

Ordered this product to fill in some gaps in my railroad tie wall. Seemed to work ok, but a can of it didn't go very far. After a couple of months the color changed from black to olive green - not good.
I would not buy this product again. Cheaper to buy the regular Great Stuff at half price and paint it after it dries.

Rated 5.0 out of 5.0 by AA Great for sealing leak on roof by chimney
I have a flat roof that had a spray foam roof over the old felt roof. The old felt flashing in the chimney came away from the chimney taking the foam with it allowing rainwater to flow down the side of the chimney into the house. I broke away some of the old felt/foam, pushed the nozzle of the can into the crack and squirted. Eventually the foal sealant came out of the crack and I no longer get water coming into the house when it rains.

I purchase a case of Great Stuff and it's name has held up! Great Stuff.
Good penetration into small and large opening that you want to remain watertight as well as decent adhesion. Pretty strong Stuff!

1/3 the price as Beckett pond spray/same stuff. Works great instead of concrete, for filling gaps, leaks, etc. Can spray paint matching color. I buy a few cans every Spring to fix the finiky pond.

Rated 5.0 out of 5.0 by pondnut Works quite well, use carefully, it's very sticky stuff!
I've used this on 3 different ponds over the last few years and it has done a great job holding rocks in place and directing water flow. It seems to hold up well as long as direct sunlight does not hit it.

Rated 5.0 out of 5.0 by Maryland Top notch pond foam
If you're looking to seal pond stones and waterfalls to direct water flow this is what you want. Great coverage. One can goes a long way but is worthless to use next day as the foam hardens and clogs the tube. So have everything ready to foam before you start. Great Stuff pond foam is GREAT
