Article No. 720001
Water-based topcoat for windows, doors and other high-value wood elements
The stated values represent typical product characteristics and are not to be construed as binding product specifications.
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%
Thoroughly remove any dirt, grease and non-adhering old coatings.
Thoroughly sand any old coatings that are still intact.
Sand grey and weathered wood surfaces down to sound, bright wood.
Observe BFS Code of Practice No. 18 "Coatings on Wood and Wooden Working Materials in Outdoor Areas".
Pre-treat wood in outdoor areas that is to be protected from soft rot and blue stain with Aqua IG-15-Impregnation Primer IT* (not necessary for wood indoors).
If a white or light-coloured top coat is used, to avoid bleeding of coloured substances contained in the wood pre-treat with Aqua AG-26 All Primer
Optimum temperature of material, surroundings and substrate: min. +10 °C - max. +25 °C. Relative humidity 50% - 65%.
Apply with a brush, roller or by spraying.
Flow cup gun: nozzle size: 2.0 - 2.5 mm; atomiser air pressure: 2.0 - 3.0 bar.
Airless spraying: nozzle size: 0.28-0.33 mm; material pressure: 70-90 bar.
Air-mix spraying: nozzle size: 0.28-0.33 mm; material pressure: 70-90 bar, atomiser air pressure 1-2 bar.
Apply further coats once dry.
Apply 2 - 3 coats with a slight intermediate sanding.
If the substrate has been pre-treated with Aqua AG-26 All Primer, 1-2 coats are suffcient.
Maintenance coating: 1 - 2 coats with a slight intermediate sanding.
Seal opened containers well and use contents as soon as possible.
Check colour, adhesion and compatibility with the substrate by setting up a trial area.
Do not use at temperatures 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.
Divide large surfaces in lanes and do not coat extensive areas at once.
Areas that are being coated or dried should be protected against rain, wind, sunlight and condensation.
Bright, intense colours such as yellow, orange and red may have a lower covering capacity as a natural consequence of the pigments used. When using these colours, it is therefore recommended either to first apply a coat of a similar colour with a greater covering capacity, or to apply a second coat in the desired colour.
Gaskets that contain plasticizers tend to become sticky in conjunction with dispersion paints. Use plasticizer-free gaskets.
Sealing compounds must be compatible with the coating and may only be applied once the coating has dried thoroughly.
Dust dry: approx. 30 minutes Touch dry: approx. 1 hour Overcoating: approx. 4 hours
Practice values at +20 °C and 65% relative humidity.
The coating may take significantly longer to dry thoroughly in lower temperatures, at high humidity or if the maximum layer thickness has been exceeded.
If necessary with water (max. 5%).
Paintbrush with acrylic bristles, flat brush, foam roller, flow cup gun, airless/airmix spraying equipment
Clean tools immediately after use with water and detergent.
Ensure that any residue from cleaning is disposed of correctly.
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.
Approx. 100 ml/m² per coat
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.
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.
