    Field of application

    • For use outdoors
    • for elements with limited dimensional stability
    • for not dimensionally stable elements
    • For use on exterior wood
    • Wood which is not in ground contact, in accordance with DIN EN 335-1, use classes 2 and 3
    • Wood building elements with no dimensional stability: e. g. fences, framework, carports, planking
    • Wood building elements with limited dimensional stability, e.g. folding shutters, matchboarding, summerhouses
    • Dimensionally stable wood building elements (when used as a primer only): e.g. windows and doors
    • Primer, intermediate and finishing coats

    Properties

    • Solvent-based
    • Natural grey tones for wood outdoors
    • Even colour tone across areas exposed to weathering and areas sheltered from weathering
    • 3 in 1: impregnation, priming and stain
    • Protects wood from moisture and provides effective protection against blue stain fungi
    • Reduces the risk of rot when used in conjunction with constructive wood protection measures
    • Increased solids content provides protection against nesting wasps
    • Protective film against mould and algae
    • Penetrates deeply
    • Breathable
    • Subsequent treatment without sanding
    • 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

        Completely remove old coatings (e.g. paints or medium-build stains), bark, bast and dirt.

        Remove loose and torn knots as well as resin that bleeds and clean with a suitable product (e.g. V 101 thinner, thinner & brush cleaner).

        Smooth, planed wood surfaces should be sanded and dusted before the coating is applied to ensure better absorption.

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

    • Application
      • Brush
      • Stir before use
      • Application temperature: min. 5 °C max. 30 °C
      • Application requirements

        Temperature of the material, air and substrate: from min. +5 °C to max. +30 °C

      • Stir well.

        Private users: Application by brush.
        Professional operations: Application by brush, dipping, flow coating; spraying only in closed facilities.

        Apply in the direction of the grain.

        Apply a second coat once the first has dried.

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

    • Application instructions
      • Drying time: can be worked over after 12 h
      • Check colour, adhesion and compatibility with the substrate by setting up a trial area.

        If the surface is overcoated with other products it is recommended to test the adhesion to the substrate.

        Rainfall may cause water soluble substances to bleed from wood that is rich in such substances, e.g. oak, red cedar, afzelia, redwood, etc. This may lead to the discolouration of light-coloured masonry or render.

        End-grain surfaces must be sealed with the corresponding colour (at least 2 applications)

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

        Pre-testing is recommended also on other woods.

        Each layer of medium-build stain results in a more intense colour and a glossier finish.

      • Drying

        Approx. 12 hours at 20 °C and 65% relative humidity.

        Low temperatures, poor ventilation and high humidity delay drying.

        Even once the coating is sufficiently dry for handling, less volatile solvents may cause surface to feel clammy to the touch over several days!

        This property does not constitute a flaw!

        The evaporation of these solvents can be accelerated by the ensuring the highest possible air exchange.

      • Thinning

        Ready to use

    • Working tools / cleaning
      • Brush
      • Brush (natural bristles)

      • Clean tools immediately after use with thinner and brush cleaner.

        Ensure that any residue from cleaning is disposed of correctly.

    • Storage / shelf life
      • Store frost-free and cool / protect for moisture / close containers
      • Store in well-sealed, original containers, out of the reach of children and in a dry, cool, well-ventilated room which is protected from direct sunlight and frost. No smoking is permitted in storage areas.

    • Usage
      • Total application/absorption rate 205 ml - 250 ml Total / m²
      • Preventive action against blue stain at 205-250 ml/m² Practical experience has shown that at least two coats are required to achieve this application quantity

      • Planed or very thick woods are less absorbent and may require a third coat

    • 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.

    • 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.
