Acid-stained Concrete Patio -- Looks like copper! Click the pic for a brief how-to video on doing this technique. I'd love to do this, although I wonder if the acid stain is bad for those plants around the patio.
Concrete pain and stain can be found at most home improvement stores as well as your typical warehouse discount store. Concrete paints can come in many colors and qualities and vary in their durability. Some concrete paint and stains need to be sealed.
