    Field of application

    • For use on walls indoors and ceilings
    • Smoothing off mould remediation systems
    • Creating fine, closed plaster surfaces that are ready for painting
    • Surface quality grades Q1 - Q2


    • Diffusion open and capillary active
    • Insusceptible to moisture
    • Good smoothing and adhesion properties
    • Stable
    • Can be used without primer on all absorbent substrates
    • Preparation
      • Substrate requirements

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

      • Preparations

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

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

        Can be sanded once set.


    • Application instructions
      • Work wet-on-wet and try not to create streaks.

        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.

    • Working tools / cleaning
      • Toothed trowel / toothed blade
      • Mixer, 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
      • 1.2 kg / mm thick layer / m²
      • Approx. 1.2 kg/m²/mm filler thickness

    • General information
      • Effectiveness against mould infestation and condensation is only guaranteed in conjunction with mould control restoration plaster and SLP CS panels.

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

        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.

        Deviations from applicable regulations must be agreed separately.

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