Mapei Ultraflex LFT Rapid – White 50 lb

Ultraflex LFT Rapid is a premium, rapid-setting, non-sag, large-and-heavy-tile mortar (formerly known as “medium-bed mortar”) and thin-set mortar for large and heavy tile and stone for interior/exterior floor, wall and countertop installations. This mortar has a high content of unique dry polymer, resulting in excellent adhesion to the substrate and tile. Thanks to MAPEI’s High-Hydrated Cement Technology (HCT ™), Ultraflex LFT Rapid offers superior drying-out characteristics for quick curing and does not contribute to efflorescence. Ultraflex LFT Rapid is FastTrack Ready ™, allowing grouting in 3 to 4 hours.
