MAPEI Keraflex Super Series 1200120 Tile Mortar, Gray, Powder, 44 lb Bag

Premium, extra smooth, large-and-heavy-tile mortar with polymer. Keraflex Super is a highly versatile, non-sag/nonslump, large-and-heavy-tile mortar and thin-set mortar for tile and stone for installations on floors, walls and countertops. This polymer-modified mortar has a high content of a unique dry polymer, resulting in excellent adhesion to the substrate and tile, with enhanced resistance to freeze/thaw environments. It is formulated with Easy Glide Technology for ease of application and with a consistency that allows adjustability when used with lippage control systems. Keraflex Super can also be used as a mortar over uncoupling, crack-isolation, sound-reduction and waterproofing membranes.
