A process for the preservation of timber comprises contacting unseasoned green wood with an aqueous impregnation medium comprising water, oil-soluble metal salt of an organic carboxylic acid, and a surfactant, and allowing the metal salt to penetrate the wood. The process can be carried out at ambient temperature and pressure, or under vacuum or superatmospheric pressure. Preferably, the metal salt is a preservative such as a fungicide, and the aqueous system also contains other desirable components such as fire retardants, coloring agents and insecticides. |
