Topps Tiles Stratum Grey 31cm x 56cm (Box of 7 Tiles) Price is per box of 7 tiles (1.2m2 per box) Inspired by geology, the Stratum grey tile features textured layers that mimic the look of sedimentary rocks. The soft coloured wall tiles fit closely together, producing a natural effect with minimal grout lines. Apply the grout with your finger to fill spaces that may occur. If tiling in a wet area, a 2mm grout line is required to ensure water doesn’t seep behind the tiles.
