The chemicals are PEG and sucrose, which have been conventionally used for the treatment of waterlogged wood. The present investigation was undertaken in order to reveal difference of the impregnation between the chemicals, but also to contribute to the explanation of the chemicals penetration process and distribution within wood structure. Comparable observation concerning the deposits shapes of chemicals after treatment, PEG4000 penetrated samples were occurred at the cell wall shrinkage and cracks, whereas the majority of the cells and lumens were entirely filled with a crystalline structure. Sucrose penetrated samples remained almost like sound wood, although the penetration ristricted only the cell walls was filled by amorphous structure.
