Natural Wood Finishes for Exteriors of Houses

Natural finishes are less durable than house paints and require more frequent renewals. On parts of a house that are fully exposed to sunshine and rain, natural finish usually needs renewal every 6 months until it has been applied three or four times, after which the intervals may be somewhat longer, though seldom more than 12 months. On more sheltered parts of the house, yearly renewal may suffice and in deep shade the intervals may be even longer. Natural finishes may be divided into three types, oil finishes, wood sealer finishes, and varnish finishes. Doors and windows usually need more careful maintenance of protective finish than is necessary on siding.
