17-229-202 Me. Code R. § 06
Facing material may be wood, composite, sheet metal or plastic. Although new material will not be a requirement, bent, damaged, poor quality, scrap, discarded, mixed or conglomerate materials will not be acceptable.
Suggested materials would be sound, new or used boards; exterior grade hardboard or plywood; corrugated steel, aluminum, or plastic.
It is suggested that all fastenings be galvanized nails, spikes, bolts, clamps, etc., and that all wood materials be treated with either a creosote oil base stain or cuprinol (with color additive) to preserve and prolong the life of the fence and to present a uniformity of appearance.
Since wind damage is a problem with any fence, bracing may be required and certainly would be essential on any fence over 8 feet in height. In board fence construction, relief of wind pressure may be achieved by placing the boarding alternately on outside and inside of stringers with the spacing to be such that edges overlap enough to present a solid appearance and effectively screen the junk yard from ordinary view.
