The DELTA LEVEL SYSTEM prevents unevenness between the installed ceramic tiles, both on floors and walls. The DELTA LS prevents tile movement during mortar placement. The basic principle of the DELTA system is to press the highest tile until its surface is level with the adjacent tile. DELTA is a system based on strips and wedges, recommended for tiles measuring 30x30 cm and larger, as well as for tiles of different thicknesses, up to 12, 15, and 20 mm, depending on the strip model. The method of use is simple and intuitive. After tile placement, the fastening elements are removed by striking (with a kick or hammer), always in the direction of the joint. DELTA wedges are reusable.
