Abstract

Impregnation of the wooden equipment used as furniture, decoration and building materials, outdoor effects and some kinds of air situations as a result of varnishing is studied in this work. Especially, the changes in the wooden material, varnish and impregnation material, used massively in furniture are studied according to seasons (spring, summer, autumn, winter) and months (3, 6, 9 and 12).  According to the results, the highest retention in Scotch pine wood occurred in water repellent + polyurethane varnish (82.02 kg/m3) and in chestnut tree wood occurred in water repellent + polyurethane varnish (9.80 kg/m3). The highest brightness level is measured in the 9th month (52.56%) for Scotch pine and in the 12th month (67.94%) for chestnut tree. The highest percentage of colour change is measured in 4th season (67.07%) for Scotch pine and also in 4th season (55.95%) for chestnuts tree. The highest percentage of adherence resistance is measured in the 9th month (3.83%) for Scotch pine and in the 3, 6 and 9th months (3.66%) for chestnut. The highest rate of weight loss is measured as 0.99 g in Scotch pine while it is 0.66 g in chestnut tree.   Key words: Impregnation, wood , varnishes, weathering , color changes, gloss.
