ABSTRACT:
The method includes the step of applying a heat shrinkable plastics sleeve to at least that part of the object most vulnerable to decay. A meltable sealing solution, typically a bituminous substance, is provided between the heat shrinkable plastics sleeve and the object. The sleeve is heated so as to melt the sealing solution sufficiently for it to bond intimately to the wooden object and pressure is applied to the plastics sleeve. The sleeve may be extruded and the sealing solution may be applied to the internal surface of the sleeve as it is extruded. Pressure can be applied to the sleeve using pressure pads, which may be heated, or by a jet of hot air.
