    Field of application

    • For use on exterior wood
    • Dimensionally stable wood building elements: e.g. windows and doors (including their interior surfaces)
    • 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
    • Biocide-free finishing coat for impregnated wood, e.g. garden furniture
    • Clear UV+ can also be used as a sacrificial layer over pigmented variants to prevent the wood from darkening


    • Weather-resistant and UV-resistant
    • High UV protection for light colours and clear UV+
    • Dirt-repellent and easy to maintain
    • Block resistant (in accordance with Code of Practice HO.03)
    • Good flow properties
    • Free from biocides and cobalt
    • 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 and torn knots as well as resin that bleeds and clean with a suitable product (e.g. V 101 thinner, thinner & brush cleaner).

        For outdoor wood that requires protection against soft rot and blue stain, pre-treat with Wood Protection Primer*, Wood Protection Cream* or HK Stain* (not required for indoor wood).

        When painting outdoor wood with the colour Clear UV+, the wood must first be pre-treated with Wood Protection Cream Clear*.

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

        Thoroughly sand any old coatings that are still intact.

    • Application
      • Application requirements

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

      • Stir well.

        Apply by brush.

        Apply in the direction of the grain.

        Carry out light intermediate sanding on particularly elegant surfaces prior to applying a finishing coat.

        Apply a second coat once the first has dried.

        If required, Clear UV+ can be used as a third coat to permanently fix the desired colour (sacrificial layer that is renewed when renovating).

        This procedure can also be carried out on surfaces that have been pre-treated with HK Stain* or Wood Protection Cream*.

        This procedure is not advisable on substrates that have been treated with white products (darkening, yellow tint from Clear UV+).

        End grain areas should be painted over with several coats of the material in the corresponding colour to protect against water absorption.

        Windows and exterior doors require 3 coats.

        All colours can be mixed with one another.

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

    • Application instructions
      • Check colour and compatibility with the substrate by applying a trial coat.

        Make sure that the area is well ventilated during processing and drying.

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

        Compatible with plastics and bituminous materials once dry.

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

        Mechanical damages, especially to clear coatings, must be immediatly repaired with "clear UV+" to prevent discolouring, caused e.g. by blue stain.

        Risk of self-ignition (DGUV information brochure 209-046).

        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

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

        Low temperatures, poor ventilation and high humidity delay drying.

      • Thinning

        Ready for use

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

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

        Ensure that any residue from cleaning is disposed of correctly.

    • Storage / shelf life
      • 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
      • First coat: 100 ml/m² Second coat: 60 ml/m²

    • 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.

    • 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.
