Abstract
A method of treating an elongate wood member is provided, the wood member having an outer surface and a cross-section. The method includes (1) forming a plurality of holes into the outer surface of the wood member; (2) introducing a treatment composition which includes a boron-containing compound into the plurality of holes; and (3) steam treating the wood member for a duration of from about 15 minutes to about 24 hours, the steam having a temperature of from about 80° C. to about 150° C. The steam treatment causes the boron-containing compound to diffuse from the formed holes into the cross-section of the wood member.
