Due to natural weathering , the colour and the surface roughness of uncoated wood is changed. However, in practice it can happen that wood in constructions has been weathered prior to application of a finish. In this work , selected properties of pine wood surface such as colour, surface roughness and stability of coating film were investig ated . The surfaces of previous naturally weathered sapwood and heartwood of pine ( Pinus sylvestris , L.) were tested . Two coating materials useable for wooden constructions in exterior conditions were used: dark brown polyurethane - based system and light bro wn oil - based surface treatment. Experiments showed that the dark brown polyurethane - based system made all the wood surface uniform in colour. It homogenized the surface colour as well as the differences in roughness which occurred as a result of pre - weathering . The light brown oil - based surface treatment did not sufficiently outweigh the colour changes and nor the surface roughness which arose as a result of pre - weathering of wood. The results of pull - off test for adhesion showed that t he polyurethan e coating film had the weakest point in the pre - weathered layer of wood substrate and also at the wood/coating interface. The oil - based surface treatment had the weakest place inside the coating film or in the coating penetration layer in the wood substrate. Pre - weathering did not significantly affect the pull - off strength of the system wood - coating film.
