In the Surface Department, surfaces of wood, wood-based or other materials (composites, mineral substrates) are provided with properties which they do not naturally have or do not acquire during the manufacturing process, but which they require for their practical use – be it for a protective function, as a decorative surface or to achieve special functionalities. Solutions are developed in the following work areas; services are offered involving the re-spective technical equipment:
