Description Product Overview ARDEX RA 54 is a two-component, fast-setting semi-rigid polyurea joint sealant designed for filling interior control joints and new construction saw-cut joints in horizontal concrete surfaces. It is specifically developed for industrial flooring applications where durability and load resistance are critical. The formulation provides rapid curing, allowing joints to be shaved within approximately 45 minutes and opened to full traffic in around 90 minutes. It is suitable for environments exposed to heavy-duty vehicle traffic such as warehouses, factories, and logistics facilities. ARDEX RA 54 can also be used externally where only minimal joint movement is expected. Key Features Fast-setting polyurea joint sealant for concrete joints Trafficable in approximately 90 minutes Can be shaved flush within approx. 45 minutes Designed for heavy-duty industrial traffic Semi-rigid formulation supports joint edges Suitable for internal and limited external use Low VOC formulation Strong adhesion to concrete substrates Applications Filling control joints in concrete slabs New construction saw-cut joints Warehouse and industrial flooring Factories and high-traffic commercial areas Concrete floors subject to heavy vehicle traffic Repair of existing joint systems in concrete slabs Notes Ensure substrate is clean, dry, and free of contaminants Do not apply to damp or uncured concrete (minimum 28 days cure) Use backer rod or sand to prevent bonding to joint base Mix components via cartridge system before application Overfill joints slightly and shave flush after approx. 45 minutes Not suitable for expansion joints or high movement joints Apply within recommended temperature range Technical Information Technical Specifications: Type Semi-rigid polyurea joint sealant Application Concrete control joints and saw-cut joints Substrates Concrete Joint Movement Capability Approx. 10–12% Shave Time Approx. 45 minutes Traffic Time Approx. 90 minutes Coverage Approx. 3 linear metres (3 x 25mm joint) Application Method Dual cartridge / caulking gun Location Internal and limited external use Colour Grey VOC 0 g/L Packaging 254mL cartridge Shelf Life Approx. 18 months (unopened) This joint sealant is designed for industrial concrete floors where edge protection and rapid return to service are essential. Its fast cure time and semi-rigid structure make it suitable for maintaining joint integrity under heavy traffic conditions.
