    Field of application

    • For use indoors and outdoors
    • for dimensionally stable elements
    • For professional users only
    • For all dimensionally stable wood building elements made of light-coloured softwood and hardwood
    • Windows, exterior doors & conservatories
    • Wood-aluminium composite structures
    • Post-rail constructions
    • Natural/Grey Protect colours for direct weathering - clear for protected structures
    • Intermediate and finishing coats

    Properties

    • Water-based
    • Cloth matt surface with very little emphasis of grain: the treated wood has a natural looking finish
    • UV absorbers reduce darkening of the wood
    • Added bonus of being resistant to scratches and hand cream when surface is subjected to normal use
    • Surfaces do not become shiny
    • Clear version of the product for protected constructions provides the best possible natural look
    • Natural colours for surfaces exposed to direct weathering: pigmented versions of the product are available for the different types of wood so as to provide a natural look with good UV protection
    • Grey Protect colours for direct weathering: grey tones that harmonise with the natural greying of the wood for a timeless appearance
    • Application
      • Temperature of the material, air and substrate: from min. +15 °C to max. +30 °C
      • Stir before use
      • Airless/airmix spraying
      • Stir well.

        Airless spraying: nozzle size: 0.28-0.33 mm; material pressure: 90-120 bar.

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

        See application examples for precise system configuration.

        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.

        Before coating technically modified woods and wood-based materials, apply the product to a trial surface and conduct a suitability test on the desired area of use.

        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.

        Carry out light intermediate sanding on particularly elegant surfaces prior to applying a finishing coat.

        Observe the waiting times between coats.

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

        Examine sealants, sealing material and foreign materials for their coating compatibility.

        Closed-pore varnishing must be carried out.

      • Drying

        Dust dry: after approx. 1 hour
        Touch dry: after approx. 2 hours
        Can be overcoated: after approx. 4 hours
        Further processing and packaging: after approx. 8 hours

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

        Low temperatures and high humidity delay drying.

      • Thinning

        Ready to use

    • Working tools / cleaning
      • Airless/airmix spraying
      • Airless or 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. 150 ml - 200 ml / m² per layer applied
      • Application rate: 150-200 ml/m²
        Wet film thickness: 150-200 μm
        Dry film thickness: 40-55 μm

      • Project-specific deviations should be determined by way of a trial coating.

        The values given are based on undiluted material.

        Protected constructions:
        Oak, clear: Induline GW-360 clear, Induline ZW-504i, Induline NW-740/05 clear
        Spruce, clear: Induline GW-306* FT 38863, Induline NW-740/05 clear
        Larch, clear: Induline GW-360 clear, Induline ZW-504i, Induline NW-740/05 clear

        Direct weathering:
        Oak, natural oak: Induline GW-360 FT 38854, Induline ZW-504i, Induline NW-740/05 FT 38855
        Spruce, natural spruce: Induline SW-900*, Induline GW-360 FT 38856,  Induline ZW-504i, Induline NW-740/05 FT 38857
        Larch, natural larch: Induline SW-900*, Induline GW-360 FT 38858, Induline ZW-504i, Induline NW-740/05  FT 38859


        Optimum transparency can be achieved by using a clear intermediate coat.
        Although the various colours are matched to a specific type of wood, they can easily be used for other types of wood as well, in which case the look of the colour will differ from the corresponding sample.

    • General information
      • Production of corrective lacquers:

        In order to repair minor damage to the lacquer (e.g. during installation), mix Induline NW-740/05 with 5% VP 20282 brushable additive (0362).

        Care and maintenance:

        Wood is subjected to great climatic and environmental stresses when outdoors. The coat is susceptible to the processes of natural ageing, wear and decomposition. Decomposition takes place at different speeds, depending on the stress (weak, average, strong) placed on the wood building element. Weathering stages may vary according to the part or element affected. To give wood the longest and best possible protection it is advisable to examine surfaces every year. Any damage found should be addressed immediately after cleaning.

        For cleaning and care, we recommend the care set for doors (2746).

        Using the care balsam contained in the set can help to extend the intervals at which maintenance is required, while retaining the uniform, cloth matt surface.

        Where necessary, repairs can be carried out by applying Induline NW-740/05 by brush, mixed with 5% VP20282 brushable additive (0362).
