BASIS OF PRODUCT DATA All technical data stated in this Product Data Sheet are based on laboratory tests. Actual measured data may vary due to circumstances beyond our control. FURTHER DOCUMENTS Sika Method Statement : Sikadur Resin Grouts ECOLOGY, HEALTH AND SAFETY User must read the most recent corresponding Safety Data Sheets (SDS) before using any products. The SDS provides information and advice on the safe handling, storage and disposal of chemical products and contains physical, ecological, toxicological and other safety-related data. APPLICATION INSTRUCTIONS SUBSTRATE QUALITY CONCRETE Concrete must be at least 28 days old. Substrates must be sound, clean, dry or matt damp but free of standing water. Substrates must be free of contaminants such as ice, dirt, oil, grease, coatings, laitance, efflorescence, surface treatments and loose friable material. STEEL Surfaces must be sound, clean, dry and free of contaminants such as dirt, oil, grease, coatings and loose friable material. SUBSTRATE PREPARATION IMPORTANT Reduced adhesion due to surface contamination Surface contaminants such as dust and loose material, including the contaminants generated during substrate preparation, can reduce the Product's performance. Before applying the Product, clean thoroughly all substrate surfaces using vacuum or dust removal equipment. 1. CONCRETE Suitable techniques for substrate preparation include the following: Abrasive blast cleaning High-pressure water blasting Needle gunning Scabbling Bush hammering Grinding Prepare the substrate mechanically using a suitable technique. 1. Clean any pockets or holes for structural fixings to remove any debris. 2. The substrate has an open-textured, gripping surface profile. STEEL Suitable techniques for substrate preparation include the following: Abrasive blast cleaning High-pressure water-blasting Grinding Prepare the substrate mechanically using a suitable technique. 1. The substrate has a bright metal finish with a surface profile to satisfy the necessary tensile adhesion strength requirement. SHUTTER FORMWORK Preconditions Where formwork is to be used, all formwork must be of adequate strength, treated with release agent and sealed to prevent leakage. Prepare the formwork to maintain a minimum 100 mm grout head to assist with placement. 1. Note: A grout box equipped with an inclined trough attached to the formwork will also improve the grout flow and reduce air voids. MIXING IMPORTANT Poor workability and unfavourable handling time due to wrong mixing When using multiple units during application, do not mix the following unit until the previous unit has been used. IMPORTANT Mix full units only. Prior to mixing all parts, mix Part A (resin) briefly using a mixing spindle attached to a slow speed electric mixer (max. 300 rpm). 1. Add Part A to Part B (hardener) and mix Parts A+B continuously for at least 3 minutes until a uniformly coloured smooth consistency mix has been achieved. 2. While mixing Parts A + B, gradually add Part C (aggregate). 3. IMPORTANT Do not mix excessively. Mix until a uniform mix is achieved. 4. APPLICATION METHOD / TOOLS IMPORTANT Damage due to excessive long-term load Sikadur resins are formulated to have low creep under long-term load. However, due to the creep behaviour of all polymer materials under load, the long
