Common Uses
Structural framing, dimensional lumber, posts and beams, exterior trim, millwork, plywood, flooring, and general carpentry
Geographic Origin
Western North America (Pacific Northwest, Rocky Mountains, coastal forests from Alaska to California)
Workability
Works very well with hand and power tools; cuts and sands easily, though sharp tools are recommended to prevent tearout along earlywood growth layers; holds nails and screws well; glues reliably
Finish Recommendations
Accepts clear oil finishes, polyurethane, lacquer, and film finishes well; applying a pre-stain conditioner is recommended before applying dark stains to prevent blotching caused by varying density in growth rings
Notable Features
Distinctive resinous/piney scent when freshly cut; prominent contrast between light earlywood and dark latewood growth rings; excellent strength-to-weight ratio
