    • Machine workable
    • Good flank adhesion
    • High sulphate resistance and low active alkali content (SR/NA)
    • Plastic-modified
    • Preparation
      • Substrate requirements

        Clean, dust-free and capable of supporting a load.

      • Preparations

        Joint depth min. 6 cm

      • Application requirements

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

      • Pre-wet the open, cleaned joint.

        Inject the first layer of mortar into the joint such that it is free of voids and press the spiral anchor into the centre.

        While the previous layer is still wet, apply the second layer of mortar such that it is free of voids. Apply the material up to a level of 2 cm below the final surface and work with a jointing iron.

        Wait at least 24 hours before applying subsequent layers.

    • Application instructions
      • Once it has hardened, mortar must not be made workable again by adding either water or more wet mortar.

        Protect wet mortar surfaces against frost, rain and drying out too quickly for at least 4 days.

    • Working tools / cleaning
      • Caulking gun / Jointing iron
      • Mixer, pointing gun, jointing iron

      • Clean tools and equipment with water before the mortar sets.

    • 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.
