Today’s tile is larger than ever.  For ceramic or porcelain tile greater than 15” (38 cm) on one or more sides and for all natural stone, the new industry standard calls for the use of a specialized mortar. 

These modified dry-set mortars (large format tile mortars) are specifically formulated for large and heavy tile.  They resist slumping to support the increased weight, promoting smoother tile installations with reduced lippage or unevenness between tiles.  Uneven tiles detract from the smooth, monolithic look of the floor, create challenging grout joints and can even present a trip and fall hazard.

CUSTOM’s unmatched family of large format tile (LFT) mortars ranges from everyday performance to high-performance options with attributes engineered to address specific jobsite issues such as crack isolation, the need for 10-year or lifetime warranties, a fast return to service or tile installation weight considerations.
