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
- Dimensionally stable wood building elements (when used as a primer only): e.g. windows and doors
- 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
- Excellent flow characteristics on untreated wood
- Outstanding (wet) adhesion
- 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
- Long-term protection with uniform weathering and no flaking
- With UV blocker
- 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.
Dimensionally stable wood building elements: wood moisture content 11-15%
Wood building elements with limited or no dimensional stability: wood moisture content max. 18%
If necessary, impregnate non-resistant woods with a wood preservative* (*Use biocides safely. Always read the label and product information before use).
Stir well, including during application or after a break in work.
Qualified specialist companies: brushing, dipping, flow-coating and spraying in closed systems only.
Apply the second coat after 2-3 hours.
When allowed to dry overnight, intermediate sanding is required.
A third coat is recommended on particularly exposed surfaces.
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.
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.
Prior to full application, please apply a test coat to a sample area under practical conditions using the desired system, then test or examine the surface properties.
Substances in oak may bleed, causing dark discolouration, when coated with water dilutable dispersion stains.
Apply forced drying to tannin-containing woods.
The best flow results on Accoya, oak and chestnut are achieved at a pH value of 9.0–9.5, corresponding to an additive content of 0.3–0.5% VP 20829 Additive (0366).
If the viscosity increases due to evaporation, this must be remedied with water (target viscosity: runout time approx. 25 s in ISO 3 cup)
Dilute with up to 10% water to improve flow properties in unfavourable conditions (elevated temperatures, low humidity). Add water to make up for any moisture lost through evaporation.
If foaming occurs in the flow coating system, it is recommended to add 0.2-1.0% VP 9325 defoaming agent - strength 2.
Overcoating: after approx. 2.5 hours
If forced drying is used, can be overcoated: after approx. 90 minutes
(20 minutes dripping/50 minutes drying phase (35 – 40 °C)/20 minutes cooling phase)
Practice values at +20 °C and 65% relative humidity.
Low temperatures, poor ventilation and high humidity delay drying.
Ready to use
Working tools / cleaning
Paintbrush, dipping tank, flow coating facility, sprayer, vacuum equipment, applicator
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.
80 - 120 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.
Observe the information sheets “Upkeep and Maintenance of Dipping Tanks and Flow Coating Facilities” and “Information on Workplace Hygiene”.
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.
