Tuscan Seamclip™ White For large format thin ceramic tile. Gauged tiles 1/8'' to less than 1/4'' thick (3mm to 6mm). Adds 1/32" (.80mm) grout joint during tile installation. The Tuscan SeamClip™ is an innovative one piece edge leveling system™ product that requires no installation tools, no soaking, and will greatly assist most anyone in the installation of stone, ceramic, marble, granite and some large format tiles. Its straightforward easy to use design helps creates a virtual lippage free installation when used on floors or walls. The Tuscan SeamClip™ interlocks the tiles, virtually creating a single flat slab surface while the setting material is curing. The interlocking design of the Tuscan SeamClip™ reduces and in most cases eliminates settling from shrinkage, as well as minimizing the possibility of warping. The Tuscan SeamClip™ reduces the need to re-lift tiles to add more mud and/or the process of shimming tiles; thus greatly increasing the speed of installation, all the while creating that much desired lippage free mirror surface.
