Content

Purpose of surface treatments on wood
Substrate wood and wood-based materials (structure, properties, areas of application)
Substrate pre-treatment (machining, resin removal, structuring, colouring)
Coating materials (composition and properties)
Coatings for wood in outdoor applications (windows, facades, balconies, decking)
Coatings for wood in interior applications (furniture, flooring)
Application techniques (manual and industrial)
Surface defects, causes and avoidance
Important standards for wood coatings

Exercises: Methods to characterise surface properties, surface defects and their causes, artificial and natural weathering
Objective (expected results of study and acquired competences)

After successful completion of the course, students can .....
....... make decisions about the need and type of surface treatments for wood and wood-based materials based on criteria of the required protective functions.
....... describe interactions between wood and coating systems (e.g. impregnation, film formation, processing quality, durability).
....... name and explain the functions of formulation components in paints and varnishes (binders, solvents and thinners, pigments, light stabilizers, additives).
....... explain and apply the steps of surface treatments on wood (e.g. surface machining, pre-treatment, colouring, impregnation, primer, coating).
....... describe and compare application methods (e.g. brushing, spraying, dipping, flow coating, rolling) with their advantages and disadvantages.
....... specify the requirements for surfaces in the most important areas of application (e.g. furniture, flooring, facades, windows, balconies, decking).
....... determine the application quantity and layer thickness of coating materials.
....... determine the physical properties of coatings (e.g. moisture protection, light protection, chemical resistance, abrasion resistance, scratch resistance, weather resistance) with the appropriate measurement methods.
