The pictures on this page are examples of  polished concrete. The top two have been stained , the bottom two have not. The top set of pictures were taken over 3 years after completion of the project. The second set was taken a month after completion.

Notice the level of shine, they are near the same and will remain so. Even after years of traffic.  Neither have been or will ever need to be waxed or have a clear finish reapplied.
