Is it an absolute must to use LFT mortar on 24x12 or is the regular VersaBond fortified ok? ($11....
Asked by CaTrekker September 27, 2020Highly recommended to use LFT. It has additives that increase bond strength and initial bond (stickiness). It also has a higher compressive strength for floor installations to support the longer tile span better. The faster/higher bond strength is what you want for walls. And, by definition, a Large Format Tile has an edge longer than 15".
