Graf Engineered White Oak
A versatile white oak foundation
The character of white oak comes from its grain as much as its color. Graf's standard engineered white oak pairs a real oak surface with a plywood structure, giving you a way to carry the same species through a carefully planned interior. Select the grade and grain pattern before judging the final look: a cleaner Select + Better mix and a more expressive Character mix are different aesthetic choices. Neither should be inferred from one attractive board in a room photograph.
Is this GRAFCORE construction?
No. This family lists a nine-ply Baltic birch core. GRAFCORE is a separate engineered construction and should be specified by name.
What is the published wear layer?
The standard 5/8-inch sample is listed with a 4 mm real-wood wear layer.
Does a sample show the final stained color?
An unfinished sample shows the wood before the final finish system. Test your chosen stain and coating on matching material.
Can I use it over concrete?
Use only a manufacturer-approved installation assembly after the slab has been assessed and moisture conditions confirmed.
Are all listed widths in stock?
The sample selector is not a full-floor stock feed. Confirm the chosen width and complete flooring quantity before ordering.
How long are the flooring boards?
Sample pieces and full-length flooring are different. Request the length range and average applicable to your quoted order.
What should I compare beside the sample?
Cabinetry, stone, paint, trim, and adjoining flooring help reveal the oak's undertone in your own light.
Compare the construction
The details that matter
The published sample specification describes 5/8-inch engineered white oak with a 4 mm wear layer and nine-ply Baltic birch. This is a different construction from GRAFCORE. Confirm the exact board thickness and core on the flooring quotation, particularly where transitions meet tile, existing wood, or stair nosings. A sample's short length is for evaluation; it is not the length specification for the eventual flooring order.
Choose width, grade and grain together
The manufacturer's sample selector includes width, grade, and grain-pattern choices. Its sample menu does not establish current stock of full-length boards. Bring your preferred combination to the project quotation and have dimensions, pack coverage, lengths, and availability confirmed together. If you are comparing rift, quartered, and plain-sawn appearances, request the matching grain samples instead of expecting one piece to represent all three.
Plan the finish and installation
Unfinished wood allows the color and protective finish to be selected as part of the installation. Include on-site preparation, sanding, coating, and curing in the project schedule. Ask the installer to review the full assembly and moisture conditions before fixing the installation method. The real-wood surface should be cared for as hardwood, not treated as a waterproof floor. Protect the finished surface from grit and standing water, and use the cleaner approved for the final coating.
