    Safety instructions

    • Use biocides safely. Always read the label and product information before using!

    Product specifications

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

    Field of application

    • For use outdoors
    • for elements with limited dimensional stability
    • for not dimensionally stable elements
    • For professional users only
    • 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


    • Water-based
    • Low-build stain
    • 3 in 1: impregnation, priming and stain
    • Protects wood from moisture and provides effective protection against blue stain fungi
    • Protection against weathering (constructive protection and the protection provided by the product) reduces the risk of blue stain and rot
    • Increased solids content provides physical protection against nesting wasps
    • Protective film against mould and algae
    • Water-based: does not give off any unpleasant odours and tools can be cleaned with water
    • Quick drying: 2 coats can be applied in one day
    • Subsequent treatment without sanding
    • Long-term protection with uniform weathering
    • Preparation
      • Substrate requirements

        The substrate must be clean, dust-free and dry.

        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. 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
      • Application temperature: min. 10 °C max. 25 °C
      • Stir before use
      • Brush
      • Application requirements

        Temperature of material, surroundings and substrate: min. +5 °C to max. +25 °C

      • Stir well.

        Qualified specialist firms: by brush

        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 2-3 h
      • Check colour, adhesion and compatibility with the substrate by setting up a trial area.

        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.

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

        Pre-testing is recommended also on other woods.

        Clear, white and hemlock are suitable for use only on not directly weathered surfaces in outdoor areas, such as roof eaves, or as base coat.

        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.

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

      • Drying

        Dust-dry: after approx. 1 hour Can be coated: after approx. 2-3 hours

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

        Low temperatures, poor ventilation and high humidity delay drying.

        Use a foamed protection foil between the single coated wood elements to avoid blocking.

      • Thinning

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

    • Working tools / cleaning
      • Brush
      • Acrylic brush, flat brush

      • 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
      • 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
      • Approx. 197 ml - 216 ml / m² per layer applied
      • Preventive protection against blue stain at 197-216 ml/m² in at least 2 applications

    • 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.

        In accordance with DIN 68800-1, wood preservation measures must be planned in a timely and careful manner in coordination with all parties involved in the construction (architect, client, contractor) taking into account legal requirements and local conditions.

    • 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.
