Abstract: A method of impregnating a polymer plastic plug with wood preservative. A first step involves dehydrating a polymer plastic plug to reduce its naturally occurring moisture content. A second step involves introducing liquid wood preservative into the polymer plastic plug while the polymer plastic plug is in a dehydrated state by immersing it in the liquid wood preservative and boiling the liquid wood preservative at temperatures that are less than that required to turn the polymer plastic plug into a molten state. In accordance with the teachings of this method liquid wood preservative is absorbed into the dehydrated polymer plastic plug in place of the naturally occurring moisture content.
