The weathering of the beech wood impregnated by pigmented linseed oil
Original language description
This study was set up to investigate the impact of deep impregnation method and surface coating using linseed oil, supplemented with a small amount of brown shade pigment, on the natural and artificial weathering of wood. The treated samples, together with the reference ones, were exposed to natural weathering (4 years) and artificial weathering (1900 hours). The change in surface structure and colour during the weathering were evaluated. For specimens subjected to artificial weathering, the wettability of the treated surface was measured before and after weathering. Impregnated and painted samples lose their brown hue during weathering, and the wood turns gray. Greater disparities become evident during natural weathering, with a more significant change in the structure of the wood surface in painted samples. On the other hand, impregnated samples significantly slowed down structural changes in wood compared to the reference. Both treatments significantly reduced water uptake before weathering, however, this effect disappeared during weathering, though the wood still absorbed less water than the reference.
