Decorative Concrete Transform your ordinary gray slab into an extraordinary floor that is elegant, affordable, and easy to maintain. The rich leathery, old-world appearance of stained concrete makes it a preferred choice for many luxury homes as well as upscale businesses. The acid staining process gives the concrete a variegated, mottled, marble-like appearance in a variety of earth tone colors. Vibrant colors are also available for accents and custom artwork. The stained concrete can also be engraved with almost any pattern imaginable.
