White Oak
Quercus alba
Hardness
Hard and durable; stands up to wear and traffic.
Overview
Red oak's tougher, water-resistant cousin. Closed cellular structure makes it the classic choice for anything that gets wet.
Commonly built
- Whiskey & wine barrels
- Adirondack chairs
- Mission-style furniture
- Boat decks
- Farmhouse tables
Appearance
Light to medium brown with an olive cast; tighter grain than red oak.

Comparable on hardness, type, and workability, useful when this species isn't available.
Working notes
Closed pores (tyloses) make it watertight and rot-resistant. Quartersawn shows dramatic ray fleck. Reacts with iron, use stainless or coated fasteners to avoid black stains.
Wood movement
A 24-inch-wide flatsawn white oak panel moves roughly 0.59 inch across a typical seasonal humidity swing (about 6% to 12% moisture content). Use the wood movement calculator to run your own board size and moisture range.

Finishing notes
Accepts stain and most finishes very well and its closed, tyloses-filled pores make it far more water-resistant than red oak. Open grain still benefits from grain filler for a smooth film finish. High tannin content reacts strongly with water and iron, which is exactly why it fumes beautifully with ammonia (traditional Arts-and-Crafts finish) and why you should avoid steel wool and use non-reactive fasteners. Excellent under oil, and a good candidate for exterior spar varnish on outdoor pieces.
Glue-up notes
Glues well with standard PVA. Dense and closed-pore, so do not starve the joint, use adequate clamping pressure and fresh glue. Wipe squeeze-out promptly; dried glue resists stain and shows through finish.
