Description Product Overview ARDEX RA 88 PLUS is a two-component, high-performance ceramic blend epoxy adhesive designed for bonding, crack repair, and general construction applications. Its non-sag, no-drip formulation allows use on horizontal, vertical, and overhead surfaces, making it suitable for a wide range of repair scenarios on site. The adhesive delivers high compressive strength, curing to a level stronger than standard concrete, and provides excellent adhesion to multiple substrates including concrete, metal, timber, brick, and stone. It also cures underwater, allowing use in damp or wet environments where traditional repair materials may not perform. ARDEX RA 88 PLUS is commonly used for crack repairs, spall patching, anchor fixing, and general structural bonding. Key Features Two-component ceramic blend epoxy adhesive Non-sag, no-drip formulation for vertical and overhead work High strength – stronger than concrete (>55 MPa) Fast curing – ready for traffic in approx. 2–3 hours Suitable for use underwater and in damp environments Excellent adhesion to multiple substrates Trowelable for patching and repair applications Internal and external use Applications Crack and spall repair in concrete Bonding concrete, metal, timber, brick, and stone Installing anchor bolts and fixtures Repairing damaged edges and joints Fixing handrails and structural components General purpose construction bonding and repair Notes Mix or dispense both components through static mixing nozzle Ensure substrates are clean, sound, and free of contaminants Apply using cartridge gun or trowel depending on application Working time approx. 20 minutes at 20–24°C Overfill slightly and finish flush as required Allow approx. 2–3 hours before full traffic or coating Suitable for horizontal, vertical, and overhead applications Technical Information Technical Specifications: Type Two-component ceramic blend epoxy adhesive Consistency Non-sag, no-drip paste Working Time Approx. 20 minutes Cure Time Approx. 2–3 hours Compressive Strength >55 MPa (greater than concrete) Coverage Approx. 6 linear metres (6x6mm bead) Substrates Concrete, metal, timber, brick, stone, block Application Method Dual cartridge gun or trowel Location Internal and external Colour Grey Packaging 254mL and 627mL cartridges This epoxy system is designed for structural bonding and repair applications where high strength and versatility are required.
