Summary:The present invention relates to a method of treating a porous substrate of wood to inhibit or reduce microbial growth in the porous substrate, comprising the step of applying an anti-microbial composition, wherein the anti-microbial composition comprises one or more quaternary ammonium compounds and does not comprise a binder polymer or resin. The invention further relates to a wood preservative composition comprising one or more quaternary ammonium compounds, to an article comprising a porous substrate of wood treated by such method, to use of one or more quaternary ammonium compounds to inhibit or reduce microbial growth in a porous substrate of wood, and to a kit of parts comprising such wood preservative composition and a coating composition comprising a binder polymer or resin. La présente invention concerne un procédé de traitement d'un substrat poreux de bois pour inhiber ou réduire la croissance microbienne dans le substrat poreux, comprenant l'étape d'application d'une composition antimicrobienne, la composition antimicrobienne comprenant un ou plusieurs composés d'ammonium quaternaire et ne comprenant pas de polymère ou de résine liant. L'invention concerne en outre une composition de conservation du bois comprenant un ou plusieurs composés d'ammonium quaternaire, un article comprenant un substrat poreux de bois traité par un tel procédé, l'utilisation d'un ou de plusieurs composés d'ammonium quaternaire pour inhiber ou réduire la croissance microbienne dans un substrat poreux de bois, et un kit de pièces comprenant une telle composition de conservation du bois et une composition de revêtement comprenant un polymère ou une résine liant.
