This leveling system was developed to bring a perfect installation for all surfaces covered with tiles. This system ensures that your tile installation will be leveled on the point tile to tile (each tile is leveled by all tiles around it). It also prevents tiles from warping as your thinset cures. An advantage to using this system is that the process of laying tiles takes less time, as you do not have to level your tiles the traditional way. For those who are uncomfortable around tools, there is a way of achieving perfectly level surfaces with the Perfect Level Master system. Wedges and clips are included as part of this system. This installation method makes it ideal for do-it-yourselfers because it requires no complicated tools. The clips are durable and disposable and available in three grout-line sizes.
