Wood preservatives

Wood preservatives for preventive treatment are used to prevent infestation of wood and wood-based materials by insects, fungi and other wood-destroying organisms.

Wood preservatives for curative treatment are used to combat infestation of wood by destructive fungi and insects, including the treatment of masonry against dry rot.
