    • Preparation
      • Substrate requirements

        The substrate must be clean, absorbent and oil-free.

      • Preparations

        Pre-wet old concrete/screed surfaces in advance (1 day before application of the product).

    • Application
      • Curtain coating / Low pressure spraying
      • Application requirements

        Temperature of material, environment and substrate: min. +5 °C to max. +25 °C.

      • Apply several generous layers of the material wet-on-wet using a flow coating procedure and without applying pressure.

        Use a rubber scraper to spread the material, then brush through with a broom.

        Remove any excess material and/or rinse with water after a suitable gel formation time (approx. 30 min).
