    Field of application

    • Concrete replacement for structurally relevant repairs
    • Concrete replacement according to
      - DIN EN 1504-3
      - Rili-SIB DAfStb 2001
      - ZTV-ING
    • Repair and anode embedding mortar for cathodic corrosion protection


    • High mechanical resistance
    • High resistance to water penetration
    • Very low shrinkage
    • Can be applied by machine
    • Freeze/thaw-resistant
    • Preparation
      • Substrate requirements

        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.

      • Preparations

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

    • Application
      • Toothed trowel / toothed blade
      • Positive mixer / Mixing silo
      • Application temperature: min. 5 °C max. 30 °C
      • Working time (+20 °C): Approx. 60 minutes


        Layer thickness

        Single layer 25 - 100 mm


        A bonding layer is required when applying manually.

        Apply wet-on-wet.


        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.


        Machine working

        Please contact Remmers Technical Service (phone +49 5432 83900) before applying with machine processing.
