I am a Jura Limestone tiler and I tiled this kitchen hall and bathroom floor with 60cm x 40 cm Jura Limestone polished tiles and it looks just great in this size. The kitchen floor was already tiled with porcelain tiles which had to be removed with a kango and then the floor had to be cleaned so it could be tiled. The customer asked for 2mm spacing which is a good size for this type of natural stone tile so we used 2mm tile spacers which you can see in some of the pictures. When I had finished tiling the floor it had to be washed thoroughly so it was perfectly clean and then I sealed it twice, this is a long process which took a day on its own and then the floor was grouted with pergamon grout and then washed and cleaned again. Its a lot more expensive to have natural stone tiles fitted than ceramic tiles or porcelain tiles because the process is so long, in general it takes twice the time to tile a natural stone floor than it does to fit a creamic ot porcelain tiled floor, but the difference really is amazing because natural stone tiles when fitted and sealed properly are fabulous and with the proper care they always will...
