Depending on the environmental conditions, wood has a certain moisture content. If this exceeds a critical value (18-20%), biological organisms can attack and degrade wood. For this reason, attempts are usually made to avoid this critical value of material moisture. However, critical moisture levels can occur due to the construction or damage. For this reason, information on the water absorption and release of wood is important for the use of this renewable raw material. However, existing experiments and regulations in standardization for this purpose are limited in their effectiveness. Especially the partial sealing, which is necessary for such experiments, is a challenge. For this reason, we carried out sorption experiments on various sealants that had not previously been investigated. The experiments showed that most of the sealants used were not diffusion-tight or showed outgassing.
