Résumé : |
Recognition of the critical problems of wood rot in exterior panel structures has led to the initiation of several research projects in the Nordic countries, in order to prevent damage of this kind. The moisture conditions in a panel are crucial to determining the risk of wood rot, unless the wood has been treated with a preservative. Presented here is a laboratory computer-based method for monitoring the moisture conditions in a test panel during a specific climate cycle. To measure the moisture content distribution, an electrical resistance method was used. The probes are connected to a computer, which monitors the moisture conditions. The method makes it possible to determine the capacity of a paint or a paint system to keep a panel in good condition. More than 40 paneled structures have been studied by this method. Panels from old structures, painted in a way found to be inadequate, were used as references. System painting has given the best results. It has also been shown that treatment of the end grain with the priming system is crucial. |
