        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

        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.

        Aqua IG-15 Impregnation Primer IT* should be used to pre-treat exterior wood which requires protection against insects, rot and blue stain - omit step for interior wood. (*Use biocides safely. Always read the label and product information before use.)

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

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

        Apply with a brush, roller or by spraying.

        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.

         

        Re-coat once dry.

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

    • Application instructions
      • Drying time: can be worked over after 6 h
      • Check colour and compatibility with the substrate by applying a trial coat.

        Do not use 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.

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

        The colour shown on the sample does not appear until the material has dried.

        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.

        The layer thicknesses must be complied with in order to attain the flow properties and hiding power.

        The gloss level can be changed from silk matt to matt by adding 5% Aqua MM-825.

      • Drying

        Dust dry: after 1–2 hours Can be overcoated: after approx. 6 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.

        Longer drying times can improve the sealing effect.

      • Thinning

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

    • Working tools / cleaning
      • By brush / By roller Airless/airmix spraying / Flow cup gun
      • Paintbrush with acrylic bristles, flat brush, foam roller, 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
      • 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. 100 - 120 ml / m² per layer applied
      • 100-120 ml/m² per coat 2 coats are required to seal off substances contained in the wood.

    • General information
      • Insulation of resins and substances contained in the wood.

        The instructions regarding coats, application volumes and drying times for the coating system must be followed to ensure the best possible insulation for water-soluble substances contained in the wood (flat surfaces and branches). The first coat can activate substances in the wood and discolour the film on the coating, which will lock the substances inside the film. The second coat of insulating product will then seal off the substances contained in the wood.

         

        At least two coats of the product are required to achieve an efficient insulating effect.

        If discolouration continues even after following these steps, we recommend contacting our RTS (Remmers Technical Service).

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

        Please check paint compatibility with plasticised seals in advance, alternatively use plasticiser-free products (e.g. TPE seals).

        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.

    • 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.

    • Safety / regulations
      • For further information on the safety aspects of transporting, storing and handling the product and on disposal and environmental matters, please see the current Safety Data Sheet.
