02 · System anatomy
The material is not a single surface.
American black walnut (Juglans nigra) in solid and veneer construction, selected for chocolate heartwood, workable medium density and refined grain; sapwood and natural lightening must be controlled, not hidden in the name.
01Finish system
Layer function
Stain, pore fill, sealer and topcoat create colour, sheen, chemical resistance and repair behaviour.
How to verify
Approve the complete system on production species/veneer with measured sheen.
02Face material
Layer function
Solid timber, natural veneer, engineered veneer, cane or lacquer determines grain continuity and edge strategy.
How to verify
Draw every visible face, grain direction, veneer cut and solid lipping.
03Core / substrate
Layer function
Solid stock, plywood, MDF or particleboard controls stability, screw holding, weight and emissions.
How to verify
Declare board manufacturer/type, density where relevant, thickness and emissions class.
04Joinery / movement
Layer function
Joints, adhesives, fasteners and cross-grain allowance transfer loads while accommodating moisture movement.
How to verify
Prototype high-load joints and show movement allowances in shop drawings.

03Window / solar gain
Conditional- Material response
- UV, heat and uneven drying shift colour and moisture across panels.
- Design control
- Use light/heat control and avoid trapping one panel face against glazing.
04Bathroom / vanity splash
Conditional- Material response
- Water enters joints, cut-outs and unsealed panel edges before face failure is visible.
- Design control
- Use suitable core, sealed cut-outs, raised details and ventilation.

This material-specific application image shows American Walnut Solid Wood on its own product and is not reused by any other material page. Final colour, pattern and finish remain subject to the approved physical sample.
Project notes
From sample to production.
01
What to specify
Define species, solid-versus-veneer construction, visual grade, moisture target, grain match, stain colour, sheen and substrate/emissions requirement. These terms prevent major tender substitutions.
02
Fabrication & detailing
Use kiln-dried components, balanced veneer construction and solid lipping to exposed edges. Coordinate movement allowances, grain direction, hardware clearances and concealed reinforcement in shop drawings.
03
Colour & finish approval
Timber and veneer are natural materials. Colour, figure and grain movement vary; a signed control sample and veneer lay-up establish the visual standard before production.
04
Care & maintenance
Wipe with a soft damp cloth and dry immediately. Use coasters and felt protection; avoid standing water, abrasive cleaners, hot objects and rapid humidity changes.
Specification note
This page is a preliminary specification guide. No value, brand reference or material name constitutes automatic compliance. Current product data, test reports, physical sample or slab and the furniture construction must be approved for each project before ordering or manufacture.
