Results showed that while all coated groups displayed good lightness stability following weathering, the non-coated (control) group produced negative lightness stability values. The coated Oriental beech had greater overall color stability than the uncoated (control) group. The specimens coated with ETO + D230 + C nanocomposite exhibited the best color stability. All uncoated and coated specimens produced negative a* and positive b* values, indicating a propensity to turn greenish or yellowish after weathering, respectively. After weathering, while the surface roughness values of all specimens increased, their gloss decreased. In addition, after weathering, all coated samples had less gloss loss and lower surface roughness than the control group. Our findings show that following weathering, Oriental beech coated with ETO + D230 + C, ETO + D230 + F, and ETO + D230 + G nanocomposites have better surface properties than ETO + D230-coated Oriental beech.
