Abstract

The invention relates to a method for pressure-impregnating wood with an impregnating agent that is at least partially liquid under the effect of pressure, especially paraffin. The aim of the invention is to achieve a high weathering and aging resistance while maintaining the strength and elasticity of the wood. According to the invention, the impregnating agent comprises a mixture of paraffin and/or waxes having different chain length and molecular size including not more than 5 % of water. The paraffins or waxes as components of the mixture are selected such that they are at least partially solid at ambient temperature and liquefy at least partially only at substantially higher temperatures, at least above 50° C. Alternatively, a mass is used as the impregnating agent that is completely liquid at least with respect to its base component paraffin or wax when the impregnation is carried out, at a temperature of 50 °C or more, and said paraffin or wax is selected such that it is solid at a temperature below 50 °C.
