      • Preparations

        Joint depth min. 2 cm or double the joint width.

        Sanded joint sides can lead to lateral detachment.

    • Application
      • Application temperature: min. 5 °C max. 30 °C
      • Caulking gun / Jointing iron
      • Pre-wet the open, cleaned joint.

        Only mix as much mortar as can be used within approx. 2 hours.

         

    • 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.

        The flank adhesion can be increased by adding ZM HF [basic] to the mixing water (ratio 1:10).

        Wait at least 24 hours before applying subsequent layers.

    • Working tools / cleaning
      • Caulking gun / Jointing iron
      • Mixing tool, suitable feed pump, trowel, jointing iron, profiling tool (e.g. tubing)

        Clean tools and equipment with water before the mortar sets.
