The method comprises the step of applying a flexible outer barrier layer to at least that part of the object most vulnerable to decay, 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 t he 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.
