Water-based low-build stain for interior and exterior wood
Downloads & documents
The stated values represent typical product characteristics and are not to be construed as binding product specifications.
Field of application
- For use on interior and exterior wood
- Soft and hard woods
- Wood building elements with limited dimensional stability, e.g. folding shutters, matchboarding, summerhouses
- Wood building elements with no dimensional stability: e.g. fences, framework, carports, planking
- Primer, intermediate and finishing coats
- Water-based: does not give off any unpleasant odours and tools can be cleaned with water
- Good flow properties
- Quick drying: 2 coats can be applied in one day
- Outstanding (wet) adhesion
- Special combination of binding agents creates an extremely hard-wearing surface
- Does not flake
- Free from film preservation and wood protection biocides
The substrate must be clean, dry, free of dust, grease and loose substances, and prepared in the correct manner.
Wood building elements with limited or no dimensional stability: wood moisture content max. 18%
Thoroughly remove any dirt, grease and non-adhering old coatings.
Sand grey and weathered wood surfaces down to sound, bright wood.
Thoroughly sand any old coatings that are still intact.
If necessary, impregnate non-resistant woods with a 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".
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, a nitrocellulose or universal thinner).
Temperature of the material, air and substrate: from min. +15 °C to max. +25 °C.
Stir well, including during application or after a break in work.
Apply with a brush, roller or by spraying.
Airless spraying: nozzle size: 0.28 mm, material pressure: 80 - 120 bar.
Airmix spraying: nozzle size: 0.28 mm, material pressure: 60-100 bar,
atomiser air pressure: 1.2-2.0 bar.
Flow cup gun: nozzle size: 1.8-2.0 mm, atomiser air pressure: 2-2.5 bar
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.
Ensure good ventilation.
Dust-dry: after approx. 1 hour
Ready for overcoating: after approx. 4 hours
(at 23 °C and 50% RH)
If forced drying is used, ready for overcoating: after approx. 20 minutes evaporation zone (at approx. 20 °C and 65 - 75% RH) / 75 minutes drying phase (approx. 45 °C, 1 m/s air circulation) / 20 minutes cooling phase
Low temperatures, poor ventilation and high humidity delay drying.
If necessary with water (max. 5%).
Working tools / cleaning
Airless/air-mix spraying equipment, flow cup gun, acrylic brush, microfibre paint roller
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
If stored unopened in its original container in a cool, dry place and protected against frost, the product will keep for at least 12 months.
100 - 150 ml/m² per coat in at least 2 coats
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.
