Methods to measure the penetration of consolidant solutions into ‘dry’ wood

Parameters that influence the penetration of a consolidant solution into wood were examined. These include the wood permeability to liquids, impregnation methods, and physicochemical properties of the consolidant solution (relative molecular weight, concentration, and viscosity). Wood permeability to liquids is determined by the preserved object and the appropriate impregnation method has to be selected with respect to the deterioration state of the specific wood object. For these reasons, modifications of physicochemical properties of the consolidant solutions are the only parameters that influence the consolidation results. Suitable methods for studying the penetration of consolidant into wood are also discussed.
