Description Product Overview ARDEX K 900 BF is a cement-based bulk fill levelling compound designed for levelling and adjusting tolerances on internal concrete subfloors prior to the installation of floor finishes. It incorporates a coarse sand aggregate and controlled flow characteristics, allowing efficient placement of thicker layers without slumping. This product is engineered for high-build applications, making it suitable for correcting uneven slabs and large floor variations in a single installation. It can be applied manually or pumped using automatic mixing equipment, improving productivity on large commercial projects. ARDEX K 900 BF also offers high strength and durability, making it suitable for areas subject to heavy-duty traffic. Key Features Designed for bulk fill applications up to 90mm thickness Coarse aggregate formulation for controlled flow Suitable for heavy-duty commercial and industrial traffic Can be pumped for large-scale installations Economical solution for thick levelling requirements Rapid hardening – thick sections set quickly Can be used as a fast set mortar with adjusted water ratio Suitable for internal concrete substrates Applications Levelling uneven internal concrete slabs Bulk fill applications in commercial and industrial projects Subfloor preparation prior to levelling compounds and floor finishes Use in warehouses, retail, and large open areas Applications requiring build-up to correct slab tolerances Notes Mix 20kg bag with approximately 3 litres of clean water Apply manually or via automatic mixing pump Designed for thick applications with minimal flow Can be used as mortar with reduced water ratio Ensure substrate is clean, sound, and properly prepared Internal use only unless otherwise approved by manufacturer Technical Information Technical Specifications: Type Cement-based bulk fill levelling compound Application Thickness Approx. 3mm – 90mm Mix Ratio Approx. 3L water per 20kg bag Coverage Approx. 1 m² per 20kg at 10mm thickness Hardening Time Approx. 4 hours at 90mm thickness (23°C) Substrates Internal concrete slabs Location Internal use Application Method Hand or pump applied Performance Suitable for heavy-duty traffic Formulation Coarse sand aggregate with controlled flow Packaging 20kg bag This levelling compound is designed for high-build applications where standard smoothing compounds are not suitable. Its ability to achieve thick fills efficiently makes it ideal for correcting slab tolerances and preparing large commercial floors prior to final finishes.
