We had the work done in October and there were dark spots that are very ugly. We have been told that the spots would only show up when it was wet and they would be gone in 60 days. The spots are there all of the time and we are way past 60 days and they are still there
We were scheduled within two weeks and except for an inclimate day, which delayed the start, work was completed on time (2-day process). The result is awesome. So much better than just a concrete floor.
