Preparation
-
Substrate requirements
The substrate must be clean, dry, free of dust, grease and loose substances, and prepared in the correct manner.
Wood moisture content: 8-12%
-
Preparations
Wash off greasy or resin-rich woods/substrates with WV-891 or V-890. Use UN-894 indoors on the construction site. Ensure good ventilation for solvents.
Softwoods: sand with P 80 - 120.
All other substrates: sand with P 180 - 320.

-
Application
-
Stir well.
Spray.
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.

-
Application instructions
-
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 product to a trial surface and conduct a suitability test on the desired area of use.
-
Drying
Dust-dry: after approx. 1 hour
Can be overcoated: after approx. 4 hours
Drying overnight improves the sealing effect (e.g. on Hevea)Practice values at +20 °C and 65% relative humidity.
Low temperatures, poor ventilation and high humidity delay drying.

General information
-
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.
-
-
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.
