        Pre-wet the substrate.

    • Application
      • Application temperature: min. 5 °C max. 30 °C
      • Toothed trowel / toothed blade
      • Application requirements

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

      • Apply the mortar and level off quickly using a template.

        Once sufficiently hardened, apply a subsequent coat of highly diffusion open and water-repellent paint (Color LA and Color SH).

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

        The type and duration of the reworking and surface treatment will influence the colour.

        Slight deviations in colour between different batches are possible.

        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).

    • Working tools / cleaning
      • Toothed trowel / toothed blade
      • Mixing tool, smoothing trowel, trowel, template(s)

        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.

    • Usage
      • 1.3 kg / mm thick layer / m²
      • Approx. 1.3 kg/m²/mm layer thickness

    • General information
      • May contain traces of pyrite (iron sulphide).

        Low chromate content in accordance with Directive 2003/53/EC.

        The characteristic data of the product were calculated under laboratory conditions at 20°C and 65% relative humidity.

        Do not use on gypsum-based substrates.

        The mixing water must be of drinking water quality.

        The colour that is obtained after drying and hardening depends on the ambient conditions and the processing method. For instance, a freshly smoothed surface will be lighter than one that is smoothed later or roughened. Different grain sizes of the same product may lead to slight differences in colour. Substrates soaked from the back may cause discolouration.

        Always set up a trial area/trial areas first.

        Alkaline binders may cause a dissolution process on non-ferrous metals.

        Current regulations and legal requirements must be taken into account and deviations from these must be agreed separately.
