This is a finished basement concrete floor that was decoratively scored into 3-1/2 foot square diagonal tiles and acid stained "Bronze," a green color with brown highlights from Decosup's Chemtone brand. This floor turned out to have a fantastic coloring and marbling effect. It was sealed with a solvent-based acrylic concrete sealer and a water-based floor finish. The decorative cuts were taken right up to the wall, something that usually is not possible after the framing and walls have been installed. It was done with special concrete engraving tools from Engrave-A-Crete.
