The test subjects were researched regarding selected properties of 2 surface systems in 2 different colours creating high gloss appearance. The main focus was put on testing the influence of the accelerated ageing process on the colour and gloss. We also focused on the mechanical properties of the polyurethane coating system, and the acrylic sheet before and after the accelerated ageing process. We were interested in comparing the properties of the 2 surface systems often used in practice. After the exposure to an accelerated ageing process the measured changes were very small. This fact was further confirmed in researching with the Fourier transform infrared spectroscopy method. The changes in properties of the surface systems were also minimal after comparing the mechanical test results of the aged and non-aged specimens. One noticeable change was only observed in testing resistance against impact. We also found out that the type of pigment affects the reflection of UV light and absorption of heat. The final results show that varnished surfaces are more resistant, and as such better suitable for use. Nonetheless, considering the fact the differences are so minimal, we can confirm that both tested surface systems are suitable to be used in furniture industry
