Corroded reinforcement is the chief cause of concrete deterioration, which prompts subsequent repairs. For repairs to be sound, contractors must ensure adequate adhesion of new patch repair materials by proper preparation of exposed reinforcing steel. ICRI’s 310.1R-2008 “Guide for Surface Preparation for Repair of Resulting from Reinforcing Steel Corrosion” states that exposed reinforcing steel should be free of any materials such as concrete, dirt and corrosion products that could interfere with repair material adhesion, although a tightly bonded light rust on the rebar surface is usually not detrimental to the bond of patch materials. When it comes to tackling reinforcement surface prep and ongoing protection, CorrVerter® MCI® Rust Primer stands out among competitor materials with clear performance and application advantages to mitigate rebar corrosion.
