    Product details Application Usage / application examples Notes

    Field of application

    • For use on floors/walls/ceilings indoors and outdoors
    • Repair and coating mortar according to DIN 19573
    • Fast-setting mortar for quick mounting of add-on parts
    • Fast grouting mortar for add-on parts
    • Placing and repairing manhole rings and manhole covers

    Properties

    • Sulphate-resistant
    • Very high early strength (capable of bearing loads after 45 minutes)
    • Very low shrinkage
    • High resistance to water penetration
    • Corrosion-inhibiting
    • 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.

    • Application
      • Application temperature: min. 5 °C max. 30 °C
      • Application by filling knife / Trowel application
      • Application requirements

        Temperature of the material, air and substrate: from min. +5 °C to max. +30 °C

      • Working time:
        (+20 °C): approx. 10 minutes

         

        Curing time:
        (+20 C): approx. 15 minutes

         

        Quick mounting

        Fill the assembly area with material, applying light pressure.

         

        Installation of duct covers

        Clean and wet joints between frame and substructure.

        Insert formwork.

        Pour in free-flowing mortar.

         

        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.

         

    • Application instructions

      • Only mix small quantities.

        Can be removed from formwork after approx. 1-2 hours (depending on the consistency and ambient conditions).

        When applied in a free-flowing consistency, the material is resistant to loading after approx. 2 hours (if early loading is required, use Betofix QR 2).

        When applied in a plastic consistency or a consistency suitable for filling, the material has high early strength and early resistance to loading.

    • Working tools / cleaning
      • Application by filling knife / Trowel application

      • Mixing tool, trowel, smoothing trowel, scraper

        Clean tools with water while the material is still fresh.

    • Storage / shelf life
      • Protect form moisture
      • Shelf-life 12 months

      • If stored in an unopened container and in a dry place, the product will keep for approx. 12 months.

    • Usage
      • 1.8 kg / l void

      • Approx. 1.8 kg/dm³

      • Apply to a large enough trial area to determine the precise amount required.

    • Disposal instructions

      • Larger quantities of leftover product should be disposed of in the original containers in accordance with the applicable regulations. Completely empty, clean containers should be recycled.
