Abstract
This study investigated the changes in surface glossiness after 100 and 300 h of accelerated weathering of beech wood (Fagus orientalis L.) that was coated with polyurethane and cellulosic and water-based varnishes after impregnation with 5% and 10% concentrations of mimosa (Acacia mollissima) and quebracho (Schinopsis lorentzii) extracts and 4.5% Tanalith-E. The highest glossiness values were observed in the untreated control samples before and after accelerated weathering. Moreover, except for the samples coated with polyurethane varnish, the surface glossiness values of other samples decreased after accelerated weathering. Among the varnish types, the polyurethane varnish showed the best result in terms of surface glossiness, with higher values being observed after the 100-h weathering period than those before weathering. Increasing the tannin concentrations from 5% to 10% resulted in a decrease in the glossiness values. Wood impregnated with mimosa and quebracho extracts and varnished with polyurethane was able to maintain both durability and surface glossiness for a longer time.
