Description Product Overview ARDEX K 15 Microtec is a high-performance, cement-based self-levelling compound formulated with microfibre reinforcement to deliver superior strength, flexibility, and crack resistance. It is designed for internal subfloor preparation across a wide range of substrates, providing a smooth, flat finish ready for floorcoverings. Utilising ARDEX Ardurapid technology, it achieves rapid strength gain and drying times, allowing installation of floor coverings in as little as 16 hours. The compound features excellent flow characteristics, enabling application at both ultra-thin depths and thicker builds without shrinkage or spalling. ARDEX K 15 Microtec is suitable for use in both above and below grade internal environments, including applications over prepared concrete, existing tiles, and moisture-controlled substrates. Key Features Rapid drying – ready for floor coverings from approx. 16 hours Microtec fibre reinforcement for added strength and crack resistance High flow properties for smooth, level finish Feather edge to any thickness in one application Non-shrinking and high early strength development Suitable for a wide range of substrates Can be bulk filled with aggregate for deeper applications Ideal for large commercial flooring projects Applications Levelling concrete and cement-based subfloors Preparation over existing ceramic tiles and quarry tiles Use over timber and steel decking (with approval) Subfloor preparation prior to vinyl, carpet, timber, and tile installation Internal commercial and residential flooring projects Applications over moisture-controlled concrete systems Notes Mix with clean water to achieve a fluid, self-levelling consistency Apply using a gauge rake and smooth with a trowel or spike roller Working time: Not specified by manufacturer Walkable in approximately 2–4 hours Install floor coverings once compound has sufficiently dried (approx. 16 hours) Bulk fill with 2–5mm aggregate for thicker applications Ensure substrate is properly prepared and primed as required Technical Information Technical Specifications: Type Cement-based self-levelling smoothing compound (Microtec fibre reinforced) Technology Ardurapid rapid drying system Application Thickness Feather edge to any thickness (extendable with aggregate) Walk-On Time Approx. 2–4 hours Ready for Floorcoverings Approx. 16 hours Coverage Approx. 4 m² per 20kg bag at 3mm Substrates Concrete, screeds, tiles, timber (with approval), steel decking (with approval) Location Internal, above and below grade Performance High early strength, non-shrinking, crack resistant Aggregate Addition 2–5mm aggregate for deep fills Packaging 20kg bag This levelling compound is designed for high-performance flooring applications where speed, strength, and finish quality are critical. Its fibre-reinforced formulation and rapid drying properties make it suitable for large-scale commercial projects requiring minimal downtime and consistent results.
