Cross-PlusMeeting an industry-wide need for tiles with a high coefficient of friction yet smooth finish, Cross-Plus is extremely easy to maintain and clean: no sealers, waxes or other surface treatments are required. Use it where you want the good looks of porcelain tile and need the durability and assurance of a utility surface. Available in two standard sizes - 8"x 8" and 12" x 12" - and a wide variety of colors. 6" x 6" is available by special order. Allow three to six weeks. Cross-Plus is not recommended for areas where water or grease may accumulate. In those areas, choose from Cross-Grip, Cross-Tread or Cross-Dot.
