A Study on the Application of Different Varnish Types on Uludağ Fir Wood and Comparison of Color Parameters

In this study, color parameters of varnished surfaces obtained after applying different types (yacht varnish, solvent-based semi-covering wood varnish and stone varnish) of varnishes to Uludağ fir (Abies nordmanniana subsp. bornmülleriana Mattf.) wood were compared. The varnished samples were compared with the unvarnished samples. According to the results, ∆E* values were calculated as 5.61 for yacht varnish, 7.06 for stone varnish, and 13.20 for transparent opaque varnish. Variance analyses revealed that varnish type was significant for all color parameters. After applying the varnishes to the wood surfaces, decreases in L* and ho values were observed compared to the control samples, while increases in C*, b*, and a* parameters were found. For all varnish types, ∆L* values were obtained as negative, while ∆a*, ∆b*, and ∆C* values were found to be positive. The study showed that changes in the color of the wood material were achieved with the varnishes used.
