This study focused on the comparison of the bonding quality of European beech (Fagus sylvatica L.) and English oak (Quercus robur L.), due to variability of moisture content (MC) in the wood. Hardwood species as a material, often yield a more difficult drying process, which can cause problems between various MC in the process of bonding. Specimens were bonded in two groups of MCs: 10/10% (control) and 6/14%. After reaching the equilibrium MC in standard conditions, specimens were cut into sample dimensions. Afterward the specimens were tested for bonding quality according to the EN 13354. In general, there is increase of the bonding quality for both hardwood species in different MC specimens. Statistically significant increase was notable in oak. With exception of the MUF adhesive, there were statistical difference between control and 6/14% MC group for oak.
