    Field of application

    • For use on walls indoors and ceilings
    • Interior use
    • Creating fine, closed plaster surfaces that are ready for painting
    • Surface quality grades Q1-Q3


    • Enables water vapour diffusion
    • Highly capillary active
    • Good adhesive power
    • Insusceptible to moisture
    • Preparation
      • Substrate requirements

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

      • Preparations

        Pre-wet the substrate so that it is slightly moist.

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

        Using a suitable tool, apply the product as a contact layer.


        Reinforcing layer

        Using a toothed trowel, apply the material in a coating thickness of 3 mm.

        Embed the fabric in the centre of the reinforcement layer while it is still wet.

        Ensure that fabric sheets overlap by at least 10 cm.


        Surface decoration

        Apply material to a thickness of approx. 2 mm over the reinforcement layer once it has set sufficiently.

        Smooth the surface using a suitable tool.

        Carry out subsequent surface treatment after material has stiffened.


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

        Depending on the ambient conditions, in heated rooms or draughty areas, use a film or similar apparatus to prevent the material from setting too quickly.

        Hairline/shrinkage cracks are safe and are not cause for complaint as they do not impair the properties of the mortar.

        An additional intermediate layer of filler must be added in order to achieve the elevated surface quality grade Q3.

    • Working tools / cleaning
      • Toothed trowel / toothed blade
      • Mixer, trowel, toothed trowel, smoothing trowel, sponge float, smoothing board

      • 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
      • 1.3 kg / mm thick layer / m²
      • Approx. 1.3 kg/m²/mm coating thickness, up to 3.0 kg/m² on average

    • General information
      • Do not work on substrates where moisture is penetrating from the rear.

        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.

        May contain traces of pyrite (iron sulphide).

        Do not use on gypsum-based substrates.

        The mixing water must be of drinking water quality.

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

        Always set up a trial area/trial areas first.

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

        The relevant test certificates must be observed when planning and carrying out work.

    • 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. Do not dispose of together with household waste. Do not allow to enter the sewage system. Do not empty into drains.
