The Montesa series is a ceramic floor tile with the look of flagstones. 6 different reliefs and 60 different motifs and shapes in the tiles. The edges are irregularly finished, just like real flagstones, so the size 15×22 is an indication. This ceramic floor tile is 11 mm thick, which is significantly thinner than real flagstones, so the tiles must be glued on a flat surface and is not suitable for a sand and mortar surface. The R12 anti-slip value makes this tile suitable for your terrace, but also suitable for indoors and as a wall tile. The PEI is II.
