    The stated values represent typical product characteristics and are not to be construed as binding product specifications.

    Field of application

    • For use indoors and outdoors
    • for dimensionally stable elements
    • for elements with limited dimensional stability
    • for not dimensionally stable elements
    • Primer and intermediate coat
    • For use on interior and exterior wood
    • Dimensionally stable wood building elements: e.g. windows and doors
    • Wood building elements with limited dimensional stability, e.g. folding shutters, matchboarding, summerhouses
    • Wood building elements with no dimensional stability: e.g. fences, framework, carports, planking

    Properties

    • Water-based
    • Highly opaque
    • Weatherproof and moisture-regulating
    • Reduces yellow stains caused by water soluble substances in the wood when light shades of finishing coat are used
    • Preparation
      • Substrate requirements

        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.

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

        Remove loose knots and any surface resin with a suitable product (e.g. Remmers Thinner & Brush Cleaner).

        Exterior wood that needs to be protected against soft rot and blue stain must be pre-treated with a suitable wood preservative* - not necessary 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
      • Application temperature: min. 5 °C max. 30 °C
      • Stir before use
      • By brush / By roller / Airless/airmix spraying
      • Stir well.

        Apply with a brush, roller or by spraying.

        Re-coat once dry.

    • Application instructions
      • Drying time: can be worked over after 12 h
      • Use the material in undiluted form.

        Check the product’s compatibility, adhesion and sealing effect on the substrate by applying to trial areas.

        Ensure sufficient ventilation when applying indoors.

        Do not use on wood impregnated with boron salts.

      • Drying

        Initially dry: approx. 1 hour
        Can be sanded: after approx. 4 hours
        Can be overcoated: after approx. 12 hours

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

        Longer drying times can improve the sealing effect.

        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.

      • Thinning

        Ready to use

    • Working tools / cleaning
      • By brush / By roller / Airless/airmix spraying
      • Brush with synthetic bristles, flat brush, mohair roller, foam roller, suitable 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. 70 ml - 80 ml / m² per layer applied
      • 2 x approx. 70 - 80 ml/m²

      • Using less than the recommended application quantity will lead to a poorer sealing effect.

    • General information
      • 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.
