The surface and profiled areas roughness of medium density fiberboard (MDF) is very important when MDF panels are used for the direct painting and thin laminating. There are many variables affecting the surface roughness, in this study, the effect of the single wood species and mixtures of species on the roughness of the surface and profiled areas were investigated. The results showed that the wood species had an effect on the roughness of the surface and especially profiled areas of MDF. Profiled MDF manufactured from 75% oak and 25% beech furnish were the roughest, with an average value of 14.20 mu m and 17.18 mu m, at 5 mm in depth from surface and core layers, respectively.
