    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. folding shutters, matchboarding, summerhouses
    • Intermediate coat for opaque and transparent systems
    • Can also be used as a base coating for protected constructions

    Properties

    • Water-based
    • Excellent flow behaviour
    • Good build on the surface
    • Good pore wetting performance
    • Excellent sanding properties
    • Less discolouration due to water-soluble substances in the wood
    • Reduces surface impairments caused by substances contained in specific types of wood (e.g. larch).
    • Reduces the tendency of the wood to turn darker as a result of a reaction to tannic acid (e.g. oak)
    • 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).

        Prime wood surfaces.

        Prime opaque (white) surfaces with Induline GW-209, GW-306 white or GW-201.

        If necessary, protect parapet joints with Induline V-Joint Protection or Induline AF-920.

    • Application
      • Stir before use
      • Temperature of the material, air and substrate: from min. +15 °C to max. +30 °C
      • Dipping / Flow coating
      • Stir well, including during application or after a break in work.

        Immersion and flow coating.

        A repeat application may be required in exceptional cases.

        Carry out intermediate sanding before applying a final coat: P 220-240, remove sanding dust.

        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.

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

        Ensure good ventilation.

        With water based coating systems, there is always a residual risk that substances contained in the wood will cause discoloration.

        Bleeding resin is a natural phenomenon and cannot be prevented by coating measures, see BFS Code of Practice No. 18.

        The product's sealing 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.

        If the viscosity increases due to evaporation, this must be rectified by adding water (target viscosity: runout time approx. 30 s in a 3 mm ISO cup).

        Dilute with up to 10% water to improve flow properties in unfavourable conditions (elevated temperatures, low humidity). Add water to make up for any moisture lost through evaporation.

        If foaming occurs in the flow coating facility, it is recommended to add 0.1–0.2% VP 21490 defoaming agent - strength 4.

        The system finder on our website www.remmers.com contains coating recommendations for specific wood types to be used when treating windows and exterior doors.

      • Drying

        Dust-dry: after approx. 1 hour Ready for sanding and overcoating: after approx. 2 - 3 hours (at 23 °C and 50% RH) If forced drying is used, ready for sanding and overcoating: after approx. 20 minutes flash-off zone (at approx. 20 °C and 65 - 75% RH) / 60 minutes drying phase (approx. 45 °C, 1 m/s air circulation) / 20 minutes cooling phase

        Low temperatures, poor ventilation and high humidity delay drying.

      • Thinning

        Dilute with water if necessary (max. 10%).

    • Working tools / cleaning
      • Dipping / Flow coating
      • Flow coating facility, dipping tank

      • 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.

    • Usage
      • Approx. 80 ml - 120 ml / m² per layer applied
      • 80 - 120 ml/m² per coat (equivalent to wet film thickness: 80 - 120 µm, dry film thickness: approx. 20 µm)
