Mapei Ultraflex LHT Professional Large & Heavy Tile Mortar, White grout packaged in a practical bucketSetting tile? Ultraflex LHT Professional Large & Heavy Tile Mortar, White is the thinset that goes between your tile and the substrate. Built for large format and heavy tile (1224 and up) where standard thinset would slump or sag under the weight. Non slump on walls, no lippage on floors. White color so it doesn't telegraph through translucent tile or light grout joints.
