I was worried that this would not "stick" to the existing concrete I had poured. It did though. I was adding some thickness to a counter I had made, the bottom was uneven and it was thin in some places. I mixed and poured and let it cure. I have now polished and smoothed the piece and this mortar has held up. The final step of adding a mortar slurry to fill the holes is yet to be done.

Works as advertised. A little tricky to get it to stick to the (basement) wall instead of my glove, but once there it is easy to smooth out with a trowel, and it hardens nicely. Can’t give it 5 stars until I see how well it lasts.
