The weathering process leads to a slow breaking down and wearing away of surface fibres, change in colour and roughening of the surface. Under extreme conditions, timber may deform, check, split and pull away from fasteners. The extent of weathering will vary with timber species and ambient conditions. Although unprotected timber has been used externally for centuries, the weathered effect is not always desirable. In most applications timber needs protection from the elements of water, cold, heat and ultra-violet light to promote a long service life. In addition to protection from the elements, finishes may provide a decorative effect.
