Arkos Black is a 32" x 32" porcelain tile with rectified edges, which allows a tighter grout joint. A glaze is fired onto the body, which is what carries the colour and pattern. A PEI 3 rating suits any residential floor. It carries an R11 slip rating, which holds up in wet areas and entrances. It is frost resistant, so it can run from an interior floor onto a covered porch or patio. A box holds 1 pieces and covers 6.88 square feet. Made in Turkey.
