Ardex S 28 Tile and Uncoupling Membrane Mortar - 40 lb bag

The Ardex S 28 MICROTEC Rapid-Set, Rapid-Dry, Super-Format Tile and Uncoupling Membrane Mortar is a high-performance, rapid drying and rapid hardening, microfiber-reinforced, polymer-modified tile and stone mortar for interior installations. Ardex S 28 is highly flexible with virtually no shrinkage and has an extended open time, making it perfect for large and super-format tile and stone installations. Due to its semi-pourable consistency, Ardex S 28 is excellent when used with Ardex FLEXBONE Uncoupling Membranes and other approved uncoupling membranes. Ardex S 28 is ideal for moisture-sensitive tile and stone such as green and light marbles because it is formulated with Ardex proprietary self-drying technology where the mix water is completely bound into the matrix. This technology eliminates water evaporation, which virtually prevents staining and warping of moisture-sensitive tile and fully cures quickly between even the largest, most dense tiles and substrates.
