      • Preparations

        Concrete surface:
        Stable, clean, dust-free
        Observe the applicable technical regulations for the following parameters:
        - Adhesive pull strength of the substrate
        - Minimum roughness/roughness depth

        Pre-wet the substrate so that it is slightly moist.

    • Application
      • Application temperature: min. 5 °C max. 30 °C
      • Mortar pump/ Trowel / Filling knife / Smoothing trowel / Mortar pump
      • Working time
        (+20 °C): Approx. 60 minutes


        Layer thickness

        Single layer: 1 - 6 mm
        In broken-out areas: up to 10 mm


        Apply product in the desired coating thickness.

        Smooth the surface using a suitable tool.

        Finish the surface once set.


        Subsequent processing

        Protect fresh mortar surfaces from wind, direct sunlight, rain and/or frost for at least 3 days so that they do not dry too quickly.
