Description Product Overview ARDEX LQ 92 is a cement-based levelling underlay specifically developed for smoothing uneven internal and external concrete substrates prior to the installation of ceramic and stone tiles. It provides a self-smoothing, pourable consistency that delivers a flat, even surface suitable for direct tiling applications. The formulation is polymer modified, allowing application from a true feather edge up to thicker sections when required. It is designed for use in tiling systems and is not recommended for use under resilient floor coverings such as vinyl. ARDEX LQ 92 is suitable for use over concrete substrates and can also be used in conjunction with underfloor heating systems when installed in accordance with ARDEX guidelines. Key Features Self-smoothing formulation for level concrete surfaces Polymer modified for improved adhesion and performance Feather edge to 25mm application capability Early walkability and tile installation from approx. 4 hours Suitable for use with underfloor heating systems Can be bulk filled with aggregate for thicker applications Compatible with ARDEX cement-based tile adhesives Designed specifically for tiling preparation Applications Levelling uneven concrete floors prior to tiling Preparation for ceramic and stone tile installations Use over internal and external concrete substrates Application in residential and commercial tiling projects Substrates incorporating underfloor heating systems Notes Mix with clean water to achieve a smooth, pourable consistency Apply using gauge rake and smooth with trowel or smoothing tool Apply from feather edge up to 10mm as standard For thicknesses above 10mm (up to 25mm), extend with aggregate Walkable and ready for tiling after approximately 4 hours Ensure substrate is clean, sound, and properly prepared Not suitable for use under vinyl or resilient floor coverings Technical Information Technical Specifications: Type Cement-based undertile levelling compound Application Thickness Feather edge – 10mm (up to 25mm with aggregate) Walk-On / Tile Time Approx. 4 hours Coverage Approx. 3.8 m² per 20kg at 3mm Substrates Concrete Location Internal and external (non freeze/thaw conditions) Application Method Hand applied (pourable, self-smoothing) Compatibility Ceramic and stone tile systems Colour Grey Packaging 20kg bag This compound is designed specifically for tile preparation, delivering a smooth, level base over concrete substrates. Its self-smoothing properties and rapid set time make it suitable for efficient tiling installations where surface accuracy is critical.
