A new kind of acidderesination agent was developed to treat Masson’s Pine （Pinus massoniana） boards （500 mm×200 mm×55 mm ）, a fast growing plantation species. The boards were treated under a low temperature and low wood to solution ratio. Compared with untreated board, the results showed that treated boards retained their original color. However, there was a small decrease in other physical and mechanical properties of boards. The treated wood is suitable as furnishing and furniture materials.
