Wood preservatives to be used for supplemental purposes are present in various forms such as powders, liquids, rods, pastes, or gels. Boron compounds have been receiving a lot of attention in supplemental treatments since they have good mobility in wood. Application of boron compounds via internal treatments is vital to stop decay to be occurred inside the wood since large wood elements are too thick to treat well the inner parts of wood. Diffusible chemicals such as borates move through moisture in the wood but do not move in dry wood. This paper evaluates a recent research project on boron-based paste formulations prepared from boron mineral ulexite and some other actives such as fluoride and copper to be used in supplemental treatments in timber structures. In the project, six different paste formulations have been developed. The pastes have been introduced into the holes in Scots pine sapwood specimens conditioned at different moisture content levels. The study is in progress and boron diffusion is now being observed at three assay zones across the specimens after 7, 30, 60 and 90-day-incubation at room temperature.
