Achieving a flat, even tile installation begins long before the first tile is set. A level subfloor is the most critical factor; even the best tile setter will struggle to prevent lippage if the foundation is uneven. Proper surface preparation, including grinding high spots or filling low spots with self-leveling underlayment, is essential. Once the substrate is prepared, the choice of trowel and the setting technique also matter. A consistent amount of mortar applied to the correct depth ensures the tiles settle evenly without being forced. In modern installations, tile leveling systems—which consist of clips and wedges or caps—have become a standard tool for minimizing lippage. These systems mechanically pull adjacent tiles to the same height while the thin-set cures, preventing the slight "settling" that can occur naturally. While these systems are highly effective, they do not replace the need for a flat subfloor. Combining proper surface preparation with the use of mechanical leveling tools ensures the highest level of accuracy and a smooth, professional finish that meets both aesthetic and safety requirements.
