What to Expect
Each board will have natural variation in grain and color. Red Oak is known for its pronounced grain pattern, which can vary in intensity from board to board. Thickness is listed as 4/4 nominal, with a finished thickness of approximately 7/8" after surfacing and sanding. Boards are milled square and straight, but slight movement can occur with changes in humidity.
Important Notes on Movement
Wood is a natural material and will move with changes in humidity. We recommend allowing boards to acclimate before final milling or installation.
Finishing Tips
Red Oak accepts stain and finish very well due to its open grain.
For most projects:
- Sand to desired smoothness
- Apply stain if desired, then finish with polyurethane or similar
