Nonvitreous tiles are usually laid in compliance with DIN 18157 according to the thin-bed method using thin-bed mortar in compliance with DIN EN 12004 or, in rarer cases, laid according to the conventional method in a mortar bed in compliance with ATV DIN 18352. The dimensions of nonvitreous tiles always vary to a minimal extent. In order to compensate these tolerances resulting from the manufacturing process, it is advisable to include corresponding joints when laying the tiles, according to the size of the tiles and the desired appearance. Information on joint widths is to be found in DIN 18 157, Part 3. For aesthetic reasons, we recommend laying rectified (cut to a precise size) nonvitreous tiles with very narrow joints. In addition to compensating the above-mentioned tolerances, joints also have the advantage of preventing water and dirt from penetrating into the tile covering. The finished tiling is generally grouted according to the slurry method with the aid of cementitious (mineral) joint mortar. The
