Russ just finished our office floors that were three different colors of concrete (red and two shades of grey) and had high low areas that needed grinding. He ground them, filled the gaps/cracks, applied two coats of charcoal colored stain, and two coats of sealer....they look amazing! The charcoal color on top of the red concrete gave the floors an old leather look, giving our new Interior Design Studio a unique look that we will be very proud of! Russ and his team we awesome to work with and I highly recommend them! Sara George, Designer
