    Field of application

    • For use on walls/ceilings indoors and outdoors
    • Concrete replacement according to
      - DIN EN 1504-3
    • Concrete replacement for non-structurally relevant repairs
    • Repair of pores, missing and broken out areas

    Properties

    • Early strength
    • Very low shrinkage
    • Well suited to overhead working
    • Can be applied by spatula and felted
    • Freeze/thaw-resistant
    • 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.

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

         

        Layer thickness

        One layer 1 - 10 mm
        Two layers < 20 mm, apply wet on wet
        < 100 mm in broken-out areas

         

        Applying corrosion protection:

        Apply slurry in 2 layers so that it covers the surface fully
        Minimum thickness of each layer: 1 mm
        Waiting time between layers: approx. 30 minutes

         

        Subsequent processing
        As per DIN EN 13670 / DIN 1045-3
