In this study, the effects of heat treatment on some physical, mechanical, wettability and bonding properties of Calabrian pine (Pinus brutia Ten.) were investigated. Specimens were exposed to heat under atmospheric pressure at four different temperatures (120, 150, 180, 210 °C) and three different time levels (2, 5, 8 hours). Weight loss, bending strength (MOR), modulus of elasticity (MOE) in bending, Young’s modulus in compression, compression strength parallel to grain, contact angle, and bonding performance using shear tests were evaluated. All of the properties of the specimens tested were affected by heat treatment of different intensity. As a result, softer treatments yielded some increase in mechanical properties, but increase of time and temperature resulted in significant decrease in mechanical properties with decreasing mass loss. Contact angle measurements before and after treatment indicated a significant increase in wood hydrophobicity. Shear strength of the specimens were diminished when time and temperature of heat treatment were increased.U radu su prikazani rezultati istraživanja učinaka toplinske obrade na neka fizikalna i mehanička svojstva, sposobnost kvašenja i svojstva lijepljenih spojeva drva kalabrijskog bora (Pinus brutia Ten.). Uzorci su izloženi utjecaju topline pod atmosferskim tlakom pri četiri različite temperature (120, 150, 180 i 210 °C) i tri različita vremena izlaganja (2, 5 i 8 sati). Primjenom smičnih testova određeni su gubitak mase, čvrstoća na savijanje (MOR), modul elastičnosti (MOE) pri savijanju, Youngov modul pri tlačnom opterećenju, tlačna čvrstoća paralelno s vlakancima, kontaktni kut i svojstva lijepljenog spoja. Toplinska obrada drva utjecala je na sva istraživana svojstva uzoraka kalabrijskog bora, ali je taj utjecaj bio različitog intenziteta. Rezultati su pokazali da blaži uvjeti toplinske obrade neznatno pridonose povećanju vrijednosti mehaničkih svojstava, a porast vremena i temperature toplinske obrade rezultirali su značajnim smanjenjem vrijednosti mehaničkih svojstava i smanjenjem gubitka mase. Mjerenje kontaktnog kuta na površini uzoraka prije i nakon toplinske obrade pokazalo je značajan porast hidrofobnosti drva. Pri povećanju vremena i temperature toplinske obrade smanjila se smična čvrstoća uzoraka
