Douglas Fir Wood Flooring

Pseudotsuga menziesii

Sample is 3/4-by-3-1/8-inch square-edge solid strip.
Top portion is finished with water-base urethane;
bottom with oil-modified polyurethane.



Color: Heartwood is yellowish tan to light brown. Sapwood is tan to white. Heartwood may be confused with that of Southern yellow pine. Radical color change upon exposure to sunlight.
Grain: Normally straight, with occasional wavy or spiral texture. Nearly all fir flooring is vertical- grain or riftsawn clear-grade material.

Variations Within Species And Grades: Wood varies greatly in weight and strength. Young trees of moderate to rapid growth have reddish heartwood and are called red fir. The narrow-ringed wood of old trees may be yellowish-brown and is known as yellow fir.


Hardness/Janka: 660; 49% softer than Northern red oak.
Dimensional Stability: Above average (change coefficient .00267; 28% more stable than red oak).
Durability: Durable but easily dented. Somewhat brittle and splinters easily, especially with age. Used for flooring, but may not be suitable for all applications due to its softness.



Sawing/Machining: Harder to work with hand tools than the soft pines.

Sanding: Sands satisfactorily.
Nailing: Good holding ability.
Finishing: Some boards develop a slight pinkish to bright salmon color when finished with some products. Because of tendency toward color change, care must be taken to avoid oversanding when refinishing an existing floor
Comments: Sometimes milled for flooring as end-grain block, which is significantly harder than plainsawn.
