This study was performed to determine the effect of bleaching chemicals on surface adhesion strength and surface roughness in Spruce wood. For this purpose, five different bleach chemicals like sodium hydroxide-hydrogen peroxide, oxalic acid, peracetic acid, peracedic acid diluted 1/3, peracedic acid diluted 1/6 and spruce wood (Piceaorientalis L. (Link.)) were used. In this study, effect of heartwood, sapwood ratio and flat, edge grained cross section surface roughness and adhesion strength on spruce wood were determined. All specimens were varnished with cellulosic varnish. Surface roughness of coated samples was also measured using a stylus method. Adhesion strength was determined according to related standards for bleaching and control samples.The results indicated that all bleaching chemicals increased the surface roughness. The highest adhesion strength was determined for the samples treated with perasetic acid bleaching. Key words: spruce; bleaching; surface roughness; adhesion strength.
