White Oak Wood Floor
Color: Heartwood is light brown; some boards may have a pinkish tint or a slight grayish cast. Sapwood is white to cream.
Grain: Open, with longer rays than red oak. Occasional crotches, swirls and burls. Plain sawn boards have a plumed or flared grain appearance; rift-sawn has a tighter grain pattern, low figuring; quarter-sawn has a flake pattern, sometimes called tiger rays or butt.
Variations Within Species And Grades: Considerable variation among boards in color and grain texture, but variations not as pronounced as in red oak.
Hardness (Janka): 1360; 5% harder than Northern red oak.
Dimensional Stability: Average (change coefficient .00365, 1% more stable than red oak).
Durability: More durable than red oak. Tannic acid in the wood protects it from fungi and insects.
Sawing/Machining: Excellent machining qualities.
Sanding: Good sanding properties.
Nailing: Good resistance to splitting; excellent holding ability.
Finishing: Absorbs finishes more evenly than red oak. Does not bleach well.
Comments: During the finishing process, tannins at the surface can react with some liquids to turn wood green or brown. This effect tends to be more pronounced with products that have a high water content, such as bleach and water-based finishes.
