The aim of this study was to investigate the effect of surface fat removal of two fatty wood species, jujube (Ziziphus jujuba) and pistachio (Pistacia mutica) on the adhesion strength of transparent coatings. Test specimens were prepared from wood with 8% moisture content and dimensions of 300×100×10 mm. The specimen’s surfaces were rinsed with thinner and industrial acetone, separately and covered with clear coat (sealer, clear and acid catalyzed). The results showed that the surface fat removal had significant effect on adhesion strength of applied coatings on wood surface. In both species the maximum value of adhesion strength was resulted in surface fat removed by industrial acetone. Finally, the maximum value of adhesion strength was also resulted from sealer - clear and acid catalyzed coating applied on surface fat removed jujube with acetone.
