Content (Syllabus outline)

• Definition and functions of surface finishing;
• overview of materials and technologies for surface coating of wood and lignocellulose materials in order to receive requested aesthetic and mechanical, physical and resistance properties:

   -materials for sanding,

   -bleaching,

   -stains and staining,

   -composition of wood coatings and their reological properties,

   -technologies for coating applications,

   -interaction of liquid finishes with wooden substrates, wetting and penetration,

   -mechanisms of physical and chemical drying/curing, drying/curing technology

-properties of dried/cured surface finishes in relation  to prevailing binder type in a coating;

• ageing of wood during exposure in exterior and fundamentals of protection of wood and surface finishes against abiotic degradation, review of artificial accelerated ageing methods;
• the most important standards in the field of surface coating of wood and lignocellulosic materials;
• theory of the most frequent wood surface coating defects, possibilities to prevent formation of coatings or at least to decrease their frequency;
