Methods and systems for self-flowing treatment of wood, bamboo or other porous materials do not require external pressure or complicated equipment. Treatment liquid flows through these porous materials through use of capillary action, the use of absorbent sheets, and differences in pressure. The treatment solution is more evenly dispersed throughout the materials.
