  • 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. thinner or brush cleaner).

      Wood building elements should be constructed so they shed and do not retain water (avoid level surfaces, open end-grain wood, capillary joints, water and moisture accumulation points, contact with splash water, sharp edges), thereby reducing the need to use wood preservatives as far as possible.

      Thoroughly sand any old coatings that are still intact.

      Exterior wood that needs to be protected against soft rot and blue stain must be pre-treated with a suitable wood preservative* (*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. 25 °C
    • Stir before use
    • Brush
    • Stir well and apply quickly using a brush.

      Apply in the direction of the grain.

      Apply a second coat once the first has dried.

      Apply a further coat if required.

      Apply several coats of the corresponding colour to end-grain surfaces to prevent them from absorbing water. Alternatively, protect end-grain surfaces by applying End-Grain Wood Preservative after the colouring primer coat.

      All colours can be mixed with one another.

      When coating continuous surfaces, only use materials with the same batch number as slight differences in colour, gloss and texture may occur.

      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.

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

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


      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.

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

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

      Only use the clear and white versions for exterior surfaces that are not exposed to direct weathering, such as soffits, etc.

      Due to the different covering properties of white and pastel varnish colours, the optical appearance may vary depending on the substrate. It must be checked in advance whether discolouration of the varnish may occur due to substances contained in the wood.

      Due to the low UV protection of these colour shades, shorter maintenance intervals must be expected.

      In order to take account of and clarify these issues, a trial surface must be prepared in order to ensure that the surface meets expectations.

      Do not use on wood impregnated with boron salts.

      It should be noted that the tests carried out by EPH could not take into account all possible scenarios that might occur in practice. For example, contact of objects and media contaminated with this product, such as rags or dust, with other highly flammable agents, such as dust containing cellulose nitrate or certain solvents, could lead to conditions that result in ignition.

      The product should not be applied at the same work stand as NC-based varnishes or stains. Collect any textiles soiled with the product (e.g. cleaning rags, work clothing) in fire-resistant waste containers and dispose of properly.

    • Drying

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

      Low temperatures, poor ventilation and high humidity delay drying.

      Drying may take longer depending on the type of wood, e.g. oak, due to substances it contains.

  • Working tools / cleaning
    • Brush
    • Brush with synthetic bristles, flat brush

      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.

      Use the contents of open containers as quickly as possible.

  • Usage
    • Approx. 80 - 100 ml/m² per coat
      At least 2 coats

  • General information
    • DIN EN 71-3 "Migration of certain elements":

      This product complies with the limits for the migration of heavy metals to children's toys according to DIN EN 71-3 and thus fulfils one of several further requirements for the safety of children's toys according to the EU "Toy Directive" (2009/48/EC).


      In principle, the product is also suitable for use on wood rich in substances (e.g. oak, robinia, acacia).
      However, reactions with the water-soluble substances in the wood may occur that result in discolouration of the coating film and thus an impaired optical appearance (this is particularly true of white and grey shades).

      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.

  • Safety / regulations
