Mapei Ultraflex RS Series 0110044 Tile Mortar with Polymer, Gray, Powder, 25 lb, Bag

Ultraflex RS is a premium-grade, single-component, high-performance, polymer-modified, rapid-setting thin set mortar for interior and exterior installations of tile. This mortar has a high-content of unique dry polymer, resulting in excellent adhesion to the substrate and tile. Ultraflex RS is a FastTrack Ready™ product, allowing grouting in 2 to 3 hr. It can be used for both interior and exterior installations of tile in most residential floor and wall applications. In commercial applications, use on interior floor and wall installations and exterior floors. Thanks to MAPE's High-Hydrated Cement Technology (HCT™), Ultraflex RS offers great drying-out characteristics for quick curing and does not contribute to efflorescence.
