This work investigated bonding strength of wood from pine, oak and nyatoh, glued with polyvinyl acetate and rubber-based contact adhesive, and exposed to accelerated soaking in water for 2, 4, 6, 12 and 24 hours. The bonding strength of each sample was determined using a universal testing unit. Surface roughness of the samples was also measured using a profilometer. Control samples had the highest bonding strength values for all three types of species. Soaked pine samples did not have any bonding strength for both adhesives, while the rest of the samples had bonding strength reduction. Oak samples had the highest average roughness value of 7.13 µm and the highest bonding strength in all conditions. Data from this work would provide initial information for utilisation of such species in bonding applications where possible water contact is expected.
