Zaprawa 456 is intended for executing the primary, re-profiling repair layer 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).
Zaprawa 456 can serve as the final finishing layer with elements requiring ideal surface smoothness, or can serve as a base for the Gładź 460 finishing coat.
- High adhesion to concrete and steel
- High durability increment
