ABSTRACT:
A process of impregnating one or more timber articles, such as timber doors, with a treatment agent in which the articles are placed in a treatment chamber which is then filled with the treatment agent. The treatment agent is then pressurized, preferably by pumping more treatment agent into the chamber, to force the treatment agent into the articles. This pressurizing step is performed quickly, for example, within between 5 and 25 seconds, and the articles are then removed from the chamber.
