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 SA2½. Reference should also be made to BS EN1504-10:2003 for specific requirements. On a well prepared and roughened substrate a bonding primer is generally not required. When a bonding primer is not required pre-wet the surface. Ensure sufficient concrete is removed from around reinforcement to allow coating and compaction of the repair material. The surface should not be allowed to dry before application of the concrete repair mortar. The surface should achieve a dark matt appearance without glistening and surface pores and pits should not contain water.
