For best installation results with Metropolitan Ceramics unglazed quarry tile, we recommend that the following be included in the specifications: Nominal 3/8" joint widths. Mix tile from several cartons of the same batch run for best shading during installation. Do not use any product containing hydrofluoric acid to clean the floor since it will attack both grout and tile.
For installation guidlines refer to the Tile Council of North America Inc. Handbook for Ceramic Tile Installation. Click here for more information on TCNA publications.
