    • Preparation
      • Substrate requirements

        The substrate must be clean, dust-free and dry.

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

        Wood elements with limited dimensional stability: wood moisture content max. 18%

      • Preparations

        Thoroughly remove any dirt, grease and non-adhering old coatings.

        Thoroughly sand any old coatings that are still intact.

        Sand grey and weathered wood surfaces down to sound, bright wood.

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

        Pre-treat exterior wood that is to be protected from soft rot and/or blue stain with Aqua IG-15* or Aqua HSL-35* - not necessary for interior wood (*Use biocides safely. Always read the label and product information before use).

    • Application
      • Application temperature: min. 10 °C max. 25 °C
      • Stir before use
      • Airless/airmix spraying / Flow cup gun / By brush
      • Stir well.

        Application by brush, spraying

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

        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 coats once dry.

        After priming, carry out light intermediate sanding.

        Apply 2 - 3 coats with a slight intermediate sanding.

        Maintenance coating: 1 - 2 coats with a slight intermediate sanding.

        Use material with the same batch number on contiguous surfaces (mix material of different batches beforehand), otherwise slight differences in colour, gloss and texture may occur.

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

    • Application instructions
      • Drying time: can be worked over after 4 h
      • Prior to full application, please apply a test coat to a sample area under practical conditions using the desired system, then test or examine the surface properties.

        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.

        If the temperature is too high or the humidity too low, the material will dry more quickly. In such cases, we recommend adding Aqua OZA-90 Open Time Additive.


        Apply Induline SW-910 to end-grain wood and cut surfaces to protect against moisture.

        Cut end-grain surfaces at the bottom to create a water-drip edge.

        Do not use on wood impregnated with boron salts.

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

        Sealing compounds must be compatible with the coating and may only be applied once the coating has dried thoroughly.

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

        Gaskets that contain plasticizers tend to become sticky in conjunction with dispersion paints. Use plasticizer-free gaskets.

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


        The clear version is not suitable for use on exterior surfaces exposed to direct weathering

        Due to the different covering properties of white and pastel varnish colours, the optical appearance may vary depending on the substrate. It must be checked in advance whether discolouration of the varnish may occur due to substances contained in the wood.

        Due to the low UV protection of these colour shades, shorter maintenance intervals must be expected.

        In order to take account of and clarify these issues, a trial surface must be prepared in order to ensure that the surface meets expectations.

      • Drying

        Dust-dry: approx. 1 hour
        Can be coated: approx. 4 hours

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

        The coating may take significantly longer to dry thoroughly in lower temperatures, at high humidity or if the maximum layer thickness has been exceeded.

      • Thinning

        If necessary, dilute with up to max. 5% water or Aqua OZA-90 Open Time Additive.

    • Working tools / cleaning
      • Airless/airmix spraying / Flow cup gun / By brush
      • Paintbrush with acrylic bristles, flat brush, flow cup gun, airless/airmix spraying equipment

      • Clean tools immediately after use with water and detergent.

        Ensure that any residue from cleaning is disposed of correctly.

    • Storage / shelf life
      • Store frost-free and cool / protect for moisture / close containers
      • Shelf-life 24 months
      • If stored unopened in its original container in a cool, dry place and protected against frost, the product will keep for at least 24 months.

    • Usage

      • Approx. 100 ml/m² per coat

    • General information
      • DIN EN 71-3 "Migration of certain elements":

        This product complies with the limits for the migration of heavy metals to children's toys according to DIN EN 71-3 and thus fulfils one of several further requirements for the safety of children's toys according to the EU "Toy Directive" (2009/48/EC).

        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.

        Observe the regulations concerning design principles for wood protection.

        Do not use on horizontal surfaces without drainage slopes and without edge radius, avoid accumulated moisture.

    • 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.
