The method comprises the step of applying a flexible outer barrier layer to at least that part of the object most vulnerable to dacay, providing a bituminous substance between the barrier layer and the object and heating the barrier layer so as to melt the bituminous substance sufficiently for it to bond intimately to the wooden object. The barrier layer may be a plastics film of heat shrinkable plastics material and may be formed into, or may be in the form of, a sleeve which is heat shrunk onto the object. The invention is particularly useful for protecting vulnerable parts of elongate wooden objects, such as fence posts or poles, from decay.
