Black Walnut Flooring
Premium black walnut flooring boards for residential and commercial projects
Overview
Black Walnut is the most luxurious domestic hardwood floor. Its rich, dark chocolate brown color — which deepens and develops warmer tones over time — creates dramatic, high-end interiors that are impossible to replicate with stain on lighter woods. Walnut's straight grain with occasional swirls and figure, combined with its excellent workability and stability, make it a premier choice for custom homes, executive offices, and upscale commercial spaces. At 1,010 lbf Janka, it's moderately hard — best suited for spaces with moderate traffic.

Installation Tips
Acclimate for 5-7 days before installation.
Nail-down, staple, or glue-down depending on application.
Maintain 3/8" expansion gap at all walls.
Mix boards from multiple bundles to blend sapwood/heartwood variation.
Walnut is softer than Oak — consider area rugs in high-traffic zones.
Use water-based poly for a natural look or oil-based for warmth.
Maintenance
Sweep or vacuum regularly to prevent scratching from grit. Use felt pads under all furniture. Clean with a hardwood floor cleaner — avoid excess water. Area rugs protect high-traffic zones. Refinish every 7-10 years. Walnut develops a richer, warmer patina over time — embrace the natural aging process.
