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

Description

Ultraflex RS is a high-performance, premium, fast-setting, polymer-modified, single-component thin-set mortar for interior and exterior tile installation. Thanks to its unique high dry polymer content, this mortar provides excellent bond strength to both the substrate and the tile. 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 and exterior floors and walls, as well as exterior floors. Thanks to MAPEI's Hyperhydration Cement 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.
