Definitions
- the invention relates to a system for coating wood materials, the
- Wood-based materials especially when they are to be stored outdoors, need a protective coating. Often the preservation of the grain of the wood material is desired, which is why thin coatings are required. For this purpose, in particular offer glazes.
- brushes or paint rollers are used. Brushes have the disadvantage that surfaces of coated with the help of brush wood materials often have an undesirable, inhomogeneous, especially a streaky appearance. Furthermore, it is difficult with brushes to limit the application of material, which limits the area performance of the coating composition, in particular the glaze. Finally, brushes show a high propensity to produce spatters when applying the coating compositions, in particular the glazes
