    • Good resistance to a wide range of commercially available hand creams
    • With the addition of SM-820: "R10" slip resistance
    • Fire resistant
    • 2K ready: additional, isocyanate-free improvement of the resistance to chemicals, scratches and abrasion, and improvement of the adhesion on glass by adding 2% Aqua VGA-485
    • Preparation
      • Substrate requirements

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

        Wood moisture content: 8-12%

      • Preparations

        Wash off greasy or resin-rich woods/substrates with WV-891 or V-890.

        Sand wood using P 100 - 180 grit.

        If colouring is desired, stain the substrate using Aqua KB-004, Aqua BB-007 or Aqua PB-006.

        The product can also be used in translucent colours for an equalising effect (e.g. on different wooden surfaces).

    • Application
      • Use Patent disperser
      • Airless/airmix spraying / Flow cup gun
      • Application temperature: min. 18 °C max. 25 °C
      • Application requirements

        Temperature of the material, air and substrate: from min. +18°C to max. +25°C.

      • Stir well.


        Flow cup gun: nozzle size: 2.0 - 2.5 mm; atomiser air pressure: 2.0 - 3.0 bar.

        Airless spraying: nozzle size: 0.23 - 0.28 mm, material pressure: 80 - 120 bar.

        Airmix spraying: nozzle size: 0.23 - 0.28 mm, material pressure: 80 - 100 bar, atomiser air pressure: 1.2 - 2 bar.

        After drying and intermediate sanding (P 240 - 320), apply a second coat of the product.

        Repeat the process if necessary.

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

    • Application instructions
      • Drying time: can be worked over after 2-3 h
      • Check colour, adhesion and compatibility with the substrate by setting up a trial area.

        For a transparent coating over surfaces coated with a coloured varnish, we recommend adding 5-10% Aqua Colour Varnish in the desired colour to the clear varnish.

        This product is marketed as a "no creaking" product when used on staircases. This is only possible if the stairs have been constructed correctly and professionally (design, accuracy of fit, wood moisture content).

        On non-wood substrates such as glass, sanded priming films, melamine resins and PU paints, adhesion can be significantly improved by adding Aqua VGA-485. Owing to the large number of possible material variants, careful checking must be carried out prior to application.

      • Drying

        Dust-dry: after approx. 45 minutes Touch-dry: after approx. 60-90 minutes Can be overcoated: after approx. 2-3 hours Can be stacked: after drying overnight

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

        Low temperatures, poor ventilation and high humidity delay drying.

      • Thinning

        Ready to use; if necessary, dilute with max. 5% water.

    • Working tools / cleaning
      • Airless/airmix spraying / Flow cup gun
      • Airless/airmix spraying equipment, flow cup gun

      • 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
