We poured then ground and polished the concrete floors in the great room and master bedroom/bathroom of a newly constructed home addition, located in Bellingham, Wash. We colored the concrete using a penetrating dye color to complement the surrounding décor. The master bedroom and bathroom are located on the second floor of the addition, and extra floor joists were required for the upstairs concrete slab. The floors, in both the upstairs master and downstairs great room, were ground to a cream level finish and polished to a 1500-grit finish.
