One of the best tools an installer has in avoiding lippage is a professional tile leveling system. Used after the surface is prepped and flattened, the leveling system consists of both clips that are placed between each tile and a wedge that interlocks the tiles at the same height. These prevent any movement during the setting process. The clips are made for every different size and thickness of tile. Tile leveling allows installers to work more quickly without sacrificing any quality while achieving the perfect lippage free finish.
