Weathering Performance of Oriental Beech (Fagus orientalis L.) Wood Impregnated with Glycerol and Glyoxal

This study aimed to improve some surface properties such as color, gloss, and roughness changes of Oriental beech (Fagus orientalis L.) wood impregnated with water repellent chemicals glycerol (GR) glyoxal (GX) after weathering. specimens were a 4 % aqueous solution GR, GX, mixture GR GX (1:1; weight : weight) (GR+GX) then exposed weathering in Muğla Province Turkey. Results showed that [delta]L* values all decreased Moreover, the decreases control specimen higher than specimens. greenish yellowish tendency, giving -[delta]a* +[delta]b* values, respectively. Total color was lowest The gloss test gave value three parameters (Ra, Rz, Rq) Among specimens, groups had, general, highest degrees most negative results roughness.
