Abstract

A method of treating timber, comprises the steps of (i) drawing an initial vacuum in the timber, (ii) contacting the timber with a liquid preservative composition comprising a solution of a preservative in an organic solvent, (iii) applying a positive pressure to the preservative composition in contact with the timber to urge the composition into the timber, (iv) removing the preservative composition from contact with the timber, (v) optionally applying a second vacuum to the timber to withdraw excess preservative composition from the timber, and (vi) contacting the timber with a gas at a positive pressure to cause the preservative composition within the timber to penetrate further into the timber. The gas is preferably compressed air.
