For sealing concrete floors (like those in the Specht Harpman project above), the firm prefers One Coat Only from osmo. The VOC-free, transparent sealer “looks great,” Harpman says, and is both “low-maintenance and easy to use.” Designed for interior or exterior use, One Coat Only is made from natural oils, as well as wax, and comes in a variety of colors. The manufacturer says it contains 85 percent solids and won't crack, flake, peel, or blister. osmo North America, 888.487.8054; www.osmona.com.
