Christoff and Finio are fans of concrete floors, but they ask their subcontractors to grind down the surface for added interest. “By grinding the slab after it has cured, you expose the aggregate polished stone,” Finio says. The grinding also tightens the pores for durability. The firm finished this floor with a clear penetrating sealer. Extreme Concrete Designs, 631.331.1665; www.extremeconcretedesign.com.
