Bold Colour, Striking Figure, Exceptional Hardness
Spotted Gum (Corymbia maculata and related species) grows along the east coast of Australia from Victoria to Queensland. Its heartwood spans an unusually wide and attractive range — pale greyish-honey, warm mid-browns, reddish tones and deep chocolate — frequently within the same piece, and its wavy, interlocked grain produces the prized fiddleback figure that architects and furniture makers seek out. The texture is moderately coarse and even. Spotted Gum is also one of the harder commercial hardwoods, with a Janka hardness around 11 kN and a density near 950 to 1,010 kg/m³. For joinery, that means exceptional resistance to dents and wear — ideal for benchtops and high-use furniture — along with genuine presence and weight. Its density rewards sharp, carbide tooling and pre-drilling, and the sapwood is lyctid-susceptible, so heartwood (or treated sapwood) should be specified.

Grades, Selection & Movement
Spotted Gum can be supplied in different grades to suit the look you are after — cleaner, lower-feature selections for a calm, uniform appearance, or character grades that showcase the natural colour variation, grain and markings that make the timber distinctive. Because timber is a natural product, every board is unique, so for visible work it pays to lay boards out and select and arrange them for colour and grain before machining, composing the piece so that tops, doors and panels read the way you intend. We can supply to your preferred grade and, where possible, provide a sample so you know what to expect. Timber movement is the other key consideration in joinery. Spotted Gum should be allowed to acclimatise to the conditions of the room or workshop where it will live before it is machined and assembled, so that it reaches a stable moisture content first. Design and detail joints, frames and panels to accommodate the small seasonal movement that all solid timber undergoes, and finish all faces and edges — including undersides and backs — so moisture is taken up and released evenly and components stay flat and true. These simple habits are the difference between joinery that lasts and joinery that twists or splits. Finally, store and handle Spotted Gum well before and during the build. Keep boards flat, evenly supported and off the floor in a dry, well-ventilated space out of direct sun, and protect machined components and finished surfaces from knocks and moisture until installation. A little care in storage keeps the timber straight and the finished joinery looking its best.

Working With and Finishing Spotted Gum
Spotted Gum is very dense, so let it acclimatise, work with sharp carbide tooling and pre-drill near ends and edges to prevent splitting; keep blades sharp for clean cuts and crisp profiles. Use adhesives suited to dense hardwoods and clamp well. Specify heartwood, or treated sapwood, given the sapwood’s lyctid susceptibility. Spotted Gum finishes superbly, its colour and fiddleback figure coming alive under oils and clear coatings; UV-stabilised finishes help hold colour where light exposure is high. Finish all faces and edges to balance moisture movement and keep tops and panels stable. For any exterior joinery, use a durable, maintained exterior coating.
