Field of application

  • For use indoors and outdoors
  • for dimensionally stable elements
  • for elements with limited dimensional stability
  • for not dimensionally stable elements
  • For professional users only
  • For use on interior and exterior wood
  • Dimensionally stable wood building elements: e.g. windows and doors
  • 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 topcoat on 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

Properties

  • Water-based
  • Non-drip
  • Weather-resistant and UV-resistant
  • High UV protection for light colours and clear UV+
  • Silk matt
  • Dirt-repellent and easy to maintain
  • Block resistant (in accordance with Code of Practice HO.03)
  • Good flow properties
  • Free from film preservation and wood protection biocides
  • Elastic
  • Preparation
    • Substrate requirements

      The substrate must be clean, dry, free of dust, grease and loose substances, and prepared in the correct manner.

      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 any loose and torn knots as well as resin that bleeds from the wood and clean with a suitable product (e.g. V 101 Thinner).

      Thoroughly sand any old coatings that are still intact.

      If necessary, the substrate can be made more uniform with Aqua RG-27.

      Exterior wood that is to be protected against insects, blue stain and rot must first be treated with Aqua IG-15 Impregnation Primer IT* - this is not necessary for interior wood (*use biocides safely. Always read the label and product information before use).

      When painting exterior 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".

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

      Apply by brush.

      Apply in the direction of the grain.

      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).

      When the colour clear UV+ is used for exterior wood, 3 coats of clear UV+ must be applied.

      Windows and exterior doors require 3 coats.

      Use material with the same batch number on contiguous surfaces (mix material of different batches beforehand), otherwise slight differences in colour, gloss and texture may occur.

      All colours can be mixed with one another.

  • 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 coating to a trial surface and conduct a suitability test on the desired area of use.

      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.

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

      Do not use on wood impregnated with boron salts.

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

      Apply Induline SW-910 to end-grain wood and cut surfaces to protect against moisture.

      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.

      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.

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

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

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

    • Drying

      Dust-dry: approx. 1 hour
      Can be coated: approx. 4 hours

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

      Low temperatures, poor ventilation and high humidity delay drying.

    • Thinning

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

  • Working tools / cleaning
    • Brush
    • Brush with acrylic 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
    • At least 36 months in unopened, original containers stored cool, dry and protected from frost.

      Use the contents of open containers as quickly as possible.

  • Usage
    • Approx. 100 ml / m² per layer applied
    • Approx. 100 ml/m² per coat
      Pigmented: 2 coats
      Clear UV+: 3 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).

       

      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.
