The article presents the results of experimental data on the determination of the physical value of the water absorption of deadwood and wood without signs of damage of Pinus sylvestris L. Since the wood with mycological lesions is poorly understood and needs additional protection when used as a material, we analyzed the kinetics of water absorption of pine sapwood on different ages of drying out in comparison with healthy wood and show the regression equations of the process. The obtained results of the research will allow to carry out qualitative forecasting of wood impregnation processes with signs of mycological damage by wood-staining mushrooms, since such material requires additional protection with antiseptic agents that are introduced into the wood mainly by aqueous solutions.
