In recent years the interest in exotic wood species has been increasing, which was caused by these species’ specific properties. The aesthetic effect of the material, especially the colour, is the most important aspect. Unfortunately, wood is susceptible to strong discolouration caused by the coating process or exposure to sunlight. This paper describes the influence of these factors on the colour stability of Asian teak, merbau and kempas wood species that are mainly used for flooring. It was proved, using spherical spectrophotometer, that uncoated wood became darker when exposed to the action of varnishes and sunlight. Lacquering, waxing and shellac lacquering of wood does not protect it against discolouration, but makes the colour more even on the whole surface.
