Description Product Overview ARDEX A 48 is a rapid set cement screed mix designed for preparing internal and external subfloors prior to the installation of floor coverings. It is specifically formulated for projects requiring fast turnaround, allowing early trafficking and installation compared to traditional screeds. The screed is suitable for bonded and unbonded applications and provides excellent strength, dimensional stability, and consistent performance. It is particularly effective when working with moisture-sensitive floor coverings due to its controlled drying characteristics. ARDEX A 48 is compatible with a wide range of finishes including tiles, membranes, resilient flooring, and parquet. Key Features Rapid set screed for fast-track installations Walkable and ready for tiling in approximately 4 hours Suitable for internal and external applications Compatible with moisture-sensitive floor coverings High strength and durable performance Suitable for bonded and unbonded screed systems Can be applied using traditional screeding methods or pumps Supports a wide range of floor finishes Applications Bonded and unbonded screeds over concrete substrates Preparation prior to tiles, membranes, and floor coverings Use under resilient, textile, and timber flooring systems Commercial and residential flooring installations Internal and external subfloor preparation Notes Mix 20kg bag with approximately 1.8 litres of clean water Working time approx. 60 minutes at 20°C Apply and finish within working time window Install bonded screeds using slurry bonding method (wet-on-wet) Minimum thickness: 15mm bonded, 35–40mm unbonded Allow sufficient curing before applying subsequent layers Do not apply below 5°C substrate temperature Technical Information Technical Specifications: Type Rapid set cement screed mix Colour Grey Mix Ratio Approx. 1.8L water per 20kg bag Working Time Approx. 60 minutes Walk-On Time Approx. 4 hours Ready for Tiles Approx. 4 hours Ready for Smoothing Compounds Approx. 24 hours Ready for Floorcoverings Approx. 48 hours Application Thickness (Bonded) Minimum 15mm Application Thickness (Unbonded) Minimum 35–40mm (max approx. 70mm) Coverage Approx. 1 m² per 20kg at 10mm thickness Consumption Approx. 20kg/m² at 10mm thickness Compressive Strength Approx. 35 MPa at 28 days Substrates New and existing concrete Location Internal and external Packaging 20kg bag Shelf Life Approx. 12 months (unopened) This screed is designed for projects where speed and performance are critical.
