The study compared surface roughness and wettability of spruce boards processed in traditional way using a hand plane with the surface roughness obtained by a modern thickness planer. Three parameters characterizing roughness Ra, Rz and Rq were measured at conditioned (MC 12%) and wetted surfaces. The contact angle was determined to show wettability of distinctly worked surfaces. Both methods achieved equal surface roughness of conditioned wood, regardless of grain orientation during measuring. Roughness increased distinctively after wetting in the case of wood planer because of grain raise in the earlywood zone of a growth ring. Hand planing probably caused compression of earlywood tracheids at a lower rate. Wetting of both surfaces was comparable in case of distilled water, slightly lower contact angle was found for machine planed surface. Use of traditional woodworking techniques is important not only to preserve traditional crafts as cultural heritage or to preserve original appearance of historical construction, but it can bring more practical benefits, e.g. in the form of more stable and higher quality surface for wood coatings.
