The important surface energy and acid-base properties for pine wood (Pinus silvestris L.) have been estimated by using two contact angle techniques (CAT), e.g., the sessile drop method Wilhelmy plate method, respectively. According to results, may be characterized as a low polymer due its energy. energy, γ s , was being larger in direction parallel grains compared with perpendicular direction. Lifshitz-van der Waals (LW) component, LW is major component AB . Furthermore, it seems that of independent choice wetting methods chemical composition surface. However, (AB) dependent on chosen. Subdivided into contributions, weaker acidic parameter, + stronger basic - Rough estimation hysteresis (CAH) roughness (SR) has also measured separately directions,
