If Applying To Concrete: The concrete shall be free from dust, loose material, surface contamination and materials which reduce bond or prevent suction or wetting by repair materials.For Steel Reinforcement: Rust, scale, mortar, concrete, dust and other loose and deleterious material which reduces bond or contributes to corrosion shall be removed to a minimum standard of SA2 1/2. Reference should also be made to BS EN1504-10:2003 for specific requirements. The edges where concrete is removed should be cut at a minimum angle of 90° to avoid undercutting and a maximum angle of 135° to reduce the possibility of debonding with the top surface of the adjacent sound concrete and should be
roughened sufficiently to provide a mechanical key between the original material and Sika Rapid Repair Mortar. Ensure sufficient concrete is removed from around reinforcement to allow coating and compaction of the repair material.On a well prepared and roughened substrate a bonding primer is generally not required.Refer to Data Sheets prior to use.
