      - Spraying parameters for colours on base A and C:

      Airmix spraying: nozzle 0.28 - 0.33 mm, material pressure: 100 - 140 bar,
      atomiser air pressure: 1.2 - 2 bar.

      Airless spraying: nozzle 0.28 - 0.33 mm, material pressure: 180 - 200 bar

      - Spraying parameters for colours on base M:
      Airless spraying: nozzle: 0.33 - 0.38 mm, material pressure 180 - 200 bar,
      Gun filter 300 - 600 µm.

      Observe the waiting times between coats.

  • Application instructions
    • Drying time: can be worked over after 6 h
    • Check colour, adhesion and compatibility with the substrate by setting up a trial area.

      Do not use at temperatures below +5°C.

      If the temperature is too low or the humidity too high, it will take longer for the material to reach the desired properties.

      Areas that are being coated or dried should be protected against rain, wind, sunlight and condensation.

       

      Divide large surfaces into strips and do not coat extensive areas all at once.

      Bright, intense colours such as yellow, orange and red may have a lower covering capacity as a natural consequence of the pigments used. When using these colours, it is therefore recommended either to first apply a coat of a similar colour with a greater covering capacity, or to apply a second coat in the desired colour.

       

      Increased resistance to scratches in interior areas can be achieved by sealing with Aqua PL-413 Parquet Varnish clear (apply with a paintbrush or roller) or Aqua TL-412 Stair Varnish clear (apply by spraying).

      Paint-on-paint contact, e.g. stacking, should be avoided.

      The layer thicknesses must be adhered to in order to achieve the product characteristics.

      For corrosion protection according to C3 long, a dry film thickness of at least 120 µm is required.

    • Drying

      Dust-dry: approx. 1 hour Touch-dry: approx. 4 hours Overcoating: approx. 6 hours

      Practice values at +20 °C and 65% relative humidity.

      Low temperatures, poor ventilation and high humidity delay drying.

      Longer drying times can improve the sealing effect.

    • Thinning

      Dilute with up to 5% water if necessary.

  • Working tools / cleaning
    • By brush / By roller / Airless/airmix spraying
    • Brush with acrylic bristles, flat brush, foam roller, Airmix/airless 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.

  • Usage
    • Approx. 100 - 120 ml / m² per layer applied
    • Bare ferrous metal: 2-3 x 100-120 ml/m² Rigid plastics, non-ferrous metal and intact old coatings: 2-3 x 100-120 ml/m² Wood: 2-3 x 100-120 ml/m²

  • General information
    • Adhesion to the substrate and adhesion of system products.
      Low temperatures, low air exchange and high humidity cause drying delays and can delay the achievement of the final bond strength for up to 7 days. This is especially true for coloured shades.

      When packing varnished elements, use materials that are plasticiser-free, permeable to air and non-adhesive.

      In the presence of air and water, aluminium forms an oxide layer that can have a negative impact on the product characteristics of coatings. Therefore, when working with aluminium, the coating must be applied immediately after pre-treating the substrate.

      The product’s insulating effect may be impaired if it is diluted too thinly, if the wood is too wet or if the recommended coating sequence, application volumes and drying times are not observed. With water-based coating systems, there is always the residual risk that substances contained in the wood will leach out.

      On planed larch and softwoods with a high resin content, the coating may have reduced adhesion and resistance to weathering. This is especially the case on horizontal year rings, knots and areas of winter growth that are high in resin. Maintenance and renovation must be carried out more frequently on these surfaces. The only remedy for this is pre-weathering or very coarse sanding (P80). If these wood types are rough-sawn, considerably longer maintenance and renovation intervals are to be expected.
