Creosote is a oil based wood preservative that protects against fungal decay and wood borers. It is a ready to use product that can be applied by dipping or painting with a brush. Creosote is dark brown-to-black after application. Creosote does not peel or flake and does not cover the natural grain of the wood. Creosote has an extremely pungent smell and is not recommended for internal use. Creosote is ideal for fencing poles and all exterior wood applications where there is minimum skin contact.
