Weather-Resistant Materials for Outdoor Building

Finishing Outdoor Building for Outdoor Durability

Even weather-resistant wood benefits from a protective finish. Apply exterior wood preservative annually, or use a Spar urethane finish that flexes with temperature changes. Avoid regular polyurethane outdoors — it cracks and peels within a year.

Elevate any outdoor building that contacts the ground using concrete piers, metal post bases, or gravel beds. Direct ground contact causes premature rot regardless of wood type.
