The Perfect Level Master levelling system was developed to guarantee that your tiles will lie perfectly flat on all surfaces. This system ensures that your tile installation will be levelled on the point of the tile so you can tile over its entire surface (each tile is levelled by all tiles around it).
It prevents tiles from warping as your adhesive cures.
It is also one of the best choices for large format tiles and stone slabs that are often bent because of their size. 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.
