• one-component
• cement-based mineral
• for anticorrosive protection of reinforcing steel
• for making a bonding layer during repairing a defect in concrete and re-profiling the element in reinforced concrete
• PCC mortar modified with polymers
• very good adhesion to concrete and reinforcing steel
• component of the KB-Cret concrete repair system
