    The stated values represent typical product characteristics and are not to be construed as binding product specifications.

    Field of application

    • For use indoors and outdoors
    • for dimensionally stable elements
    • for elements with limited dimensional stability
    • For professional users only
    • For use on interior and exterior wood
    • Soft and hard woods
    • Dimensionally stable wood building elements: e.g. windows and doors
    • Wood building elements with limited dimensional stability: e.g. matchboarding, facade elements

    Properties

    • Water-based
    • Good pore wetting performance
    • Outstanding (wet) adhesion
    • UV-curing: very quick handling
    • High UV protection thanks to special binder
    • Preparation
      • Substrate requirements

        The substrate must be clean, dry, free of dust, grease and loose substances, and prepared in the correct manner.

        Dimensionally stable wood building elements: wood moisture content 11-15%

        Wood building elements with limited or no dimensional stability: wood moisture content max. 18%

      • Preparations

        If necessary, impregnate non-resistant woods with a wood preservative* (*Use biocides safely. Always read the label and product information before use).

        Observe BFS Code of Practice No. 18 "Coatings on Wood and Wooden Working Materials in Outdoor Areas".

    • Application
      • Stir before use
      • Airless/airmix spraying
      • Temperature of the material, air and substrate: from min. +15 °C to max. +30 °C
      • Application requirements

        Temperature of the material, air and substrate: from min. +15 °C to max. +30 °C

      • The values given are based on undiluted material. The best spraying pattern is achieved if the material has a temperature of 15-20 °C.

        Airless spraying: nozzle size: 0.28-0.33 mm; material pressure: 70-90 bar.

        Air-mix spraying: nozzle size: 0.28-0.33 mm; material pressure: 70-90 bar, atomiser air pressure 1-2 bar.

        Apply further coatings after drying and UV curing

        Seal opened containers well and use contents as soon as possible.

    • Application instructions
      • Drying time: can be worked over after 4 h
      • Check colour, adhesion and compatibility with the substrate by setting up a trial area.

        Substances in oak may bleed, causing dark discolouration, when coated with water dilutable dispersion stains.

        To prevent any substances in the wood from becoming active, forced drying should be carried out.

        The product is not self-crosslinking and must be cured using a suitable UV lamp

        Ensure good ventilation.

        Observe current standards and guidelines for coating wood building elements outdoors (Codes of Practice issued by the German Association of Window and Facade Manufacturers (VFF), Code of Practice No. 18 issued by the German Federal Committee for Paint and the Protection of Material Assets (BFS), guidelines issued by the German Lacquer and Printing Ink Association (VdL) and ift guidelines issued by the Institut für Fenstertechnik).

      • Drying

        Physical drying: UV curing: after approx. 4 hours (at 23 °C and 50% RH) UV curing after forced drying: after approx. 20 minutes evaporation zone (at approx. 20 °C and 65 - 75% RH) / 45 minutes drying phase (approx. 45 °C; 1 m/s air circulation) UV curing: Lamp types: Ga+Hg Lamp power: 80-120 watt/cm² Cross-linking energy values: clear UV+ & light colours 500 - 800 mJ/cm² dark colours 800 - 1000 mJ/cm² Distance between object and lamp: 20-30 cm These parameters are guide values. Precise parameters are determined on a customer-specific basis. Can be sanded and overcoated: after 10 minutes cooling phase

      • Thinning

        Ready to use

    • Working tools / cleaning
      • Airless/airmix spraying
      • Spraying equipment

      • Clean tools with water or Aqua RK-898 Cleaning Concentrate immediately after use.

        Ensure that any residue from cleaning is disposed of correctly.

    • Storage / shelf life
      • Shelf-life 12 months
      • Store frost-free and cool / protect for moisture / close containers
      • If stored unopened in its original container in a cool, dry place and protected against frost, the product will keep for at least 12 months.

        Always close the container and protect the contents from sunlight.

    • Usage
      • Approx. 100 ml - 150 ml / m² per layer applied
      • 100 - 150 ml/m² per coat (plus spraying loss) (corresponds to wet film thickness: 100 - 150 μm, dry film thickness: 20 - 30 μm)
