I purchased the piece for the stone/concrete description and was surprised when I pulled it out of the box.  It was very porous and more like bare, unfinished plaster of paris.  Up close, it’s not white but sort of grungy white-gray.  I expected this to mold or get super dirty, fast.   On one side it had scrapes and scuffs on the contours, and there were many plaster-like smudges and divots along it others.  I ended up painting it with a metallic chalk-white rustoleum to help protect its clean surface, as well as to help hide the flaws.  It’s whiter, but still not a nice solid color.  I’ll probably need to spray the entire thing again to help protect against moisture, as it’s supposed to be for covered outdoor use in PA.
