Ardex S 28 Tile and Uncoupling Membrane Mortar - Fast. Strong. Shrink-Free
Ardex S 28 MICROTEC is a high-performance, microfiber-reinforced, polymer-modified mortar engineered for interior tile and stone installations.
Formulated with Ardex proprietary self-drying technology, Ardex S 28 rapidly binds water within the mix, eliminating shrinkage and preventing staining or warping of moisture-sensitive tile and stone. With its semi-pourable consistency, it delivers full coverage beneath large and super-format tiles and is excellent for use with Ardex FLEXBONE and other uncoupling membranes.
Walkable and grout-ready in just 4 hours, combines speed, strength, and flexibility — making it the ultimate solution for fast-track, demanding tile projects.
