Formulated with ARDEX proprietary self-drying technology, ARDEX S 28 is fully dry in just 4 hours when installing even the largest, most dense tiles. Suitable for interior use, ARDEX S 28 is a high-performance rapid setting and drying, thin to medium bed mortar with a unique semi-pourable consistency for ease of application and a much easier ability to obtain full coverage when installing large and super format tile.
ARDEX S 28 is highly flexible with virtually no shrinkage and delivers an unmatched open time for a rapid set mortar (45 minutes). Its semi-pourable consistency also makes ARDEX S 28 the perfect choice for installing ARDEX FLEXBONE Uncoupling Membranes and most other uncoupling membranes.
