Description Product Overview ARDEX A 46 is a rapid hardening, rapid drying, slump-free repair mortar designed for both internal and external concrete repairs. It is formulated to deliver high strength, shrinkage-free performance, making it suitable for demanding repair and resurfacing applications across floors, walls, and stairs. Developed for fast-track projects, it allows early foot traffic and coating installation, reducing downtime on site. The mortar is easy to mix and apply, providing a smooth finish suitable for subsequent coatings or coverings. ARDEX A 46 is ideal for forming ramps, coves, and patching damaged areas, and performs reliably on both dry and damp concrete substrates. Key Features Rapid hardening and rapid drying for fast-track installations Slump-free consistency for vertical and horizontal applications Trafficable in approximately 2–4 hours Shrinkage-free finish with high durability Suitable for internal and external use Can be applied from 2mm to 30mm in one application Excellent adhesion to concrete substrates Suitable for forming ramps, coves, and patch repairs Applications Repairing concrete floors, walls, and stair treads Resurfacing damaged or worn concrete areas Filling cracks, holes, and surface defects Forming ramps and coves Preparation prior to coatings such as epoxy, polyurethane, and membranes Commercial and industrial flooring projects Notes Mix with clean water to achieve a workable consistency Working time approx. 15–20 minutes at 20°C Apply using a steel trowel to required thickness Install between 2mm and 30mm in one application Bulk fill deeper sections with aggregate where required Ensure substrate is clean, sound, and free from contaminants Suitable for application over damp concrete Technical Information Technical Specifications: Type Rapid hardening repair mortar Colour Grey Working Time Approx. 15–20 minutes at 20°C Walk-On Time Approx. 2–4 hours Ready for Coatings Approx. 24 hours Application Thickness 2mm – 30mm (bulk fill up to approx. 50mm) Coverage Approx. 1.4 kg/m² per mm thickness Substrates New and existing concrete (moist or dry) Location Internal and external use Coating Compatibility Epoxy, polyurethane, membranes, tiles Packaging 20kg bag This mortar is designed for high-performance repair work where fast return to service is critical.
