Any concrete experts in here? Or contractors that are familiar enough with concrete?

[QUOTE="AintShePurty, post: 14447159, member: 19660"] dads been doing concrete high-rises in san diego for over 30 years now. had him take a look and automatically said this is from "burning" the concrete in with trowel machines which was my guess but I knew he'd know for sure. Basically going over and over....and over and over concrete with the troweling machines (like you stated they used) until the concrete becomes dark (almost black looking) and very slick and shiny. I've worked with him for over 13 years now as well, and sealer is never applied the same day the concrete is poured. It has to cure before you can seal it. If anything, they used what we call "cure" go figure. The stuff we use is white and somewhat milky and sprays on just as a sealer would. This only helps it cure faster, at least in our case.
