The Richard Zlatunich Residence included lots of concrete including a stout foundation, driveways, porches, stairs and landings; but one of the main features of his house was his interior floors. The floors were cast with a Tom Ralston Concrete proprietary mix design and then acid stained with 3-coats of dark brown acid stain. Richard says, “the floors have held up well to my grandchildren and still maintain a dark and luxurious look; actually they look a lot like aged leather.” Zlatunich who is an architect by trade also said, “we have lived in many different homes with tile, wood and stone floors but we have become fans of concrete.”
