    Field of application

    • For use on walls/ceilings indoors and outdoors
    • Concrete replacement for structurally relevant repairs
    • Concrete replacement according to
      - DIN EN 1504-3
      - Rili-SIB DAfStb 2001
      - ZTV-ING
      - ZTV-W LB 219
    • Repair and anode embedding mortar for cathodic corrosion protection
    • Dry spraying

    Properties

    • High carbonation resistance
    • High resistance to water penetration
    • Very low shrinkage
    • Well suited to overhead working
    • 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.

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

    • Application
      • Spraying
      • Application temperature: min. 5 °C max. 30 °C
      • Layer thickness:
        Vertical: single layer 8 - 25 mm
        Horizontal overhead: single later 8 - 20 mm
        multi-layer 16 - 60 mm
        Broken-out areas partially up to 100 mm

         

        Waiting time per application
        Approx. 120 minutes at 5 °C
        Approx. 45 minutes at 23 °C
        Approx. 30 minutes at 30 °C

         

        For optimum spraying results (low rebound, high compaction), the mixture should be applied at a nozzle distance of approx. 1 metre and a spraying angle of 90°.

         

        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.

         

    • Application instructions
      • Machine processing only.

    • Working tools / cleaning
      • Positive mixer / Mixing silo
      • Spraying
      • Mixing apparatus Rotor machines such as the Mader WM 14 are suitable for pneumatic conveyance in dry-spraying processes.
