Optimizing requirements for wood coatings
Bednářová, Ilona ; Petránek, Vít (referee) ; Vaněrek, Jan (advisor)
The work deals with wood coating systems. It is focused on the theoretical division of paints due to different aspects, moreover on testing of wood coating systems. In the practical part of the work, the experimental work regarding the influence of weather conditions onto durability of different wood coatings system was preceded. They were compared two different coatings within the basic tests in different environments.

Optimization of methods for determining the durability of wood coating systems
Škvařil, Michael ; Žák, Antonín (referee) ; Vaněrek, Jan (advisor)
The bachelor thesis deals with the optimization of methods for determining the durability of wood coating systems. The theoretical part deals with a detailed analysis of wood coating systems, including the specification of their composition, especially with a focus on modern water-borne coating systems. In the practical part an experiment was carried out, where on the selected types of coatings applied to lumber was performed analysis of selected durability parameters of coatings after exposure to short-term and long-term exposure to degradation factors

Influence of material base of coating systems onto wood durability
Bednářová, Ilona ; Petránek, Vít (referee) ; Vaněrek, Jan (advisor)
The thesis deals with the influence of the base material of the coating systems for wood durability when we exposed them to external conditions. The theoretical part is devoted to wood durability and weather resistance with a detailed description of the tests the durability of coating systems. A substantial part of the theory is devoted to description binder component of the coating material. In the practical part was performed the experiment, which examined the influence of the thickness of the coating system, the type of coating material (paint or lasure) as well as the type of binder (water dispersion with an alkyd or acrylic resin, respectively solution coating system with the alkyd resin). All coating systems were exposed to natural and artificial durability tests. The criterions for evaluation were chosen differences of colours.

Vliv dlouhodobé expozice modřínového dřeva s povrchovou úpravou na jejich vlastnosti v závislosti na umístění v exteriéru
Benák, Martin
The aim of this thesis is the detection of changes ongoing in time on exposed larch wood samples coated with water-soluble stain paint depending on the intensity of weather conditions associated with the orientation on the cardinal point and the season. The thesis is supported by laboratory measurement which took place in Department of Furniture, Design and Living at Mendel University in Brno. One coating system in three different shades was studied in exterior. Half of the samples were impregnated and half were exposed without impregnation. The measured values were compared to reference samples which were kept in dark environment without air for the whole time of exposure.
