Özet
This study aimed to determine the effect of accelerated weathering on gloss, surface hardness and colour changes of Scots pine (Pinus sylvestris L.). Test samples were impregnated with Adolit KD?5, Wolmanit CX?8 and Celcure AC?500 covered with cellulosic and polyurethane varnishes. The results showed that the values of surface hardness and gloss increased after accelerated weathering. While the surface hardness of Scots pine was increased for impregnated and polyurethane?coated varnish, it decreased for impregnated and cellulosic varnish?coated Scots pine after 1000 hours of accelerated weathering exposure. Copper?based chemical impregnation and varnish coating developed the gloss of Scots pine specimens relative to the surface characteristics observed in single?coated Scots pine specimens. While the most appropriate chemical was Celcure AC?500 for surface hardness, it was Adolit KD?5 for the gloss of Scots pine after 1000 hours of accelerated weathering exposure. Wood specimens impregnated prior to the application of varnish were more effective in stabilising the colour of Scots pine than Scots pine only coated with varnish. Polyurethane varnish? treated Scots pine showed better colour stability for each partial and total accelerated weathering exposure period. The total colour changes were lowest for polyurethane varnish?coated Scots pine impregnated with Celcure AC?500 after 1000 hours of accelerated weathering exposure.
