    • Preparation
      • 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.

        Reinforcement:
        Degree of purity SA 2 ½ if applying corrosion protection, otherwise SA 2

    • Application
      • Application temperature: min. 5 °C max. 25 °C
      • Mortar cover / Filling knife / Trowel application
      • Drying time: can be worked over after 20 minutes
      • Working time
        (+20 °C): approx. 20 minutes

         

        Layer thickness

        Single layer 1.5 - 10 mm
        Two layers < 20 mm, apply wet-on-wet
        In broken-out areas < 100 mm

         

        Applying corrosion protection:

        Apply two layers of slurry with a thickness of min. 1 mm each, making sure the entire surface is covered.

        Waiting time between layers: approx. 30 minutes.

         

        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.

         

    • Working tools / cleaning
      • Mortar cover / Filling knife / Trowel application
      • Mixing tool, paintbrush, filling knife, trowel, smoothing trowel, sponge float, plasterer’s float
