Downloads & documents
The stated values represent typical product characteristics and are not to be construed as binding product specifications.
Field of application
- Preparing opaque, pigmented varnishes
- Solid wood & veneers
- Wood materials
- Woods rich in active substances such as ash, oak, whitewood/yellow poplar
- High-quality furniture
- Wooden stairs
- In damp rooms (kitchens and bathrooms)
- Interior finishing work: e.g. panels, borders, cladding & interior doors
- Single-component: simple and economical handling
- Excellent sealing effect (moisture and water-soluble substances in the wood)
- Primer for coatings that emphasise pores
- Good sanding properties
- Low risk of wearing through
- Can be coated over with Aqua and PUR varnishes
- 2K-Ready: further, isocyanate-free increase of adhesion to priming films by adding 2% Aqua VGA-485
The substrate must be clean, dry, free of dust, grease and loose substances, and prepared in the correct manner.
Wood moisture content: 8-12%
Wash off greasy or resin-rich woods/substrates with WV-891 or V-890.
Softwoods: sand with P 80 - 120.
All other substrates: sand with P 180 - 320.
Airless spraying: nozzle size: 0.23 - 0.28 mm, material pressure: 80 - 120 bar.
Airmix spraying: nozzle size: 0.23 - 0.28 mm, material pressure: 80 - 100 bar, atomiser air pressure: 1.2 - 2 bar.
Flow cup gun: nozzle size: 2.0 - 2.5 mm; atomiser air pressure: 2.0 - 3.0 bar.
Once dry, carry out intermediate sanding with P 240-320.
Repeat the process if necessary.
Intermediate and final coats of suitable products can be applied after drying.
Seal opened containers well and use contents as soon as possible.
Woods rich in active substances must be primed twice for optimum isolation.
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.
Dust-dry: after approx. 1 hour Can be overcoated: after approx. 4 hours A drying overnight improves the sealing effect Finishing coat with PUR CL-240: after drying overnight
Practice values at +20 °C and 65% relative humidity.
Low temperatures, poor ventilation and high humidity delay drying.
Ready to use
Working tools / cleaning
Airless/Airmix spraying equipment, flow cup gun
Clean tools with water or Aqua RK-898 Cleaning Concentrate immediately after use.
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.
120 - 150 ml/m² per coat
The product’s insulating effect may be impaired if it is diluted too thinly, if the wood is too wet or if the recommended coating sequence, application volumes and drying times are not observed. With water-based coating systems, there is always the residual risk that substances contained in the wood will leach out.
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.
