Mapei Ultraflex RS - White 50 lb - Premium Mortar with Fast Setting Polymer

Ultraflex RS is a high-performance, premium quality, thin-set, rapid-setting, polymer-modified, single-component mortar for interior and exterior tile installation. Thanks to its high content of unique dry polymer, this adhesive cement provides excellent adhesion to the support and tiles. Ultraflex RS is a FastTrack Ready product allowing grouting within 2 to 3 hours. It can be used for interior and exterior tile installation in most residential floor and wall applications. For commercial applications, it can be used on interior floors and walls as well as exterior floors. Using MAPEI’s Hyperhydration Cementitious Technology (HCT), Ultraflex RS has superior drying characteristics for rapid curing and does not contribute to efflorescence. When mixed with water, Ultraflex RS meets or exceeds the requirements of ANSI A118.4F, ANSI A118.11 and ANSI A118.15F for rapid setting mortars.
