Abstract

The invention relates to a process and a means for protecting wood material against decomposition and similar undesirable reactions provoked by micro- organisms. According to the process, the wood material is treated with a wood protection agent which combats the growth and spread of micro-organisms. According to the invention, a preparation is used containing crude tall oil. Preferably, a composition of crude tall oil is used, in which the weight relationship between the fatty acids and the resin acids is greater than 1 and which contains ca. 45-70% fatty acids and ca. 40-10% resin acids, the remainder of the composition consisting of neutral substances. The wood protection agent consists, for example, of a composition of crude tall oil which has been made from a softwood-soap mixture and diluted with a suitable solvent, such as white spirit, pinene turpentine or xylene, and to which drying agent has possibly been added.
