Application

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. 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 MonoTop -614F repair mortar.

Ensure sufficient concrete is removed from around reinforcement to allow coating and compaction of the repair material. The concrete substrate should be pre-soaked with clean potable water continuously for 2 - 6 hours prior to repair mortar application. Immediately before pouring repair mortar, remove all excess or standing water from within the repair area, any form work, cavities or pockets.
