The DELTA TILE LEVELING SYSTEM from RUBI is ideal for laying large format ceramic tiles (minimum size required: 12”x12”) using the back-buttering technique. The DELTA TILE LEVELING SYSTEM prevents the movement of parts when the adhesive is setting and improves the resulting surface flatness. Thanks to the DELTA system, the professional installer sees how work time is reduced and the profitability of installation work improves, both in floor and wall tiles. The DELTA TILE LEVELING SYSTEM was created to save time in installing large format tiles, particularly in rectified porcelain tiles, as well as to ensure perfect installation and leveling with any material and dimensions. The pressure exerted on the DELTA tile wedges, thanks to the strips and the nippers, makes it a great solution to save time and get the best results in the installation of ceramic tiles.
