This master thesis deals with the application of various types of surface treatments on selected tropical wood species and the subsequent change of colour due to the effect of natural and simulated UV radiation. Measurements were performed on the following three species: zebrano (Microberlinia brazzavillensis), panga panga (Millettia Stuhlmannii) and african padouk (Pterocarpus soyauxii). As surface treatment were used water-based, polyurethane, oil and solvent-based paint. Samples were exposed to simulated UV radiation. The total duration of radiation was 168 hours. After that the colour changes delta E* were measured by using a spectrophotometer. The aim was to compare the different paints used on all woods and their colour change. The thesis also includes research of light permanency of coating exposed to natural UV radiation.
