I saw an advertise for Ultimate Concrete Coatings and called them to put that coating over my concrete. There was a really deep crack in the concrete, and they had to work much harder than they had anticipated, so it did cost me a little more than the original quote, but they did a wonderful job. I don't feel as if the price was too much for the work they did. It took them 3 days. I've had people come and ask me who did the work, and, of course, I tell them. I would use their services again. The guys were very nice and friendly.
