Zaprawa 451 is intended for executing contact layers (adhesive bridge) and to provide anti-corrosive protection in the concrete repair system.

The system can be used to repair concrete, damaged reinforced concrete affected by mechanic or corrosive factors. The system is suitable for repairing such elements as: balconies, terraces, supports, piles, lintels, etc. it may be also used to execute local repairs or fill minor cavities in other concrete surfaces (e.g. ASR).

Offering high carbonation resistance, the system provides sufficient protection of reinforcing steel against corrosion.

It is a binding layer between the repaired concrete or reinforced concrete element and Zaprawa 456 or Gładź 460.
