The 14 mm board is an overlay: it must be glued or nailed to a continuous subfloor, or direct-stuck to a concrete slab over a moisture barrier, and cannot span joists. Both are tongue-and-groove and end-matched, and both are sanded and coated after laying, so the finished floor looks the same; the 14 mm board is cheaper per square metre and sits lower at doorways.\u003c\/p\u003e\n\u003ch2\u003eWhat NSW Spotted Gum flooring is like\u003c\/h2\u003e\n\u003cp\u003eNSW Spotted Gum (\u003cem\u003eCorymbia maculata\u003c\/em\u003e) is the hardest floor we stock: WoodSolutions puts the seasoned hardness at 10.1 kN at about 990 kg\/m³. The colour is the point of it. Boards run from pale brown through chocolate to a dark red-brown, often with a wavy grain, so no two packs are alike and the finished floor has movement in it.

Leave 10–12 mm expansion gaps at walls and fixed points, more across a wide room. Leave the laid floor about two weeks before sanding and coating so it settles (WoodSolutions).

It is considered one of the darkest brown species found in Australia. Additionally, QLD Spotted Gum is truly hard-wearing and its strong nature makes it highly resistant to scratches and dints. It has a Janka hardness rating of 11.0, which places it among the tougher hardwoods commonly used in residential and commercial spaces. That level of hardness means it resists dents and wears well, even in high-traffic areas.\u003c\/p\u003e\n\u003cp\u003eIt’s also rated BAL 29, making it suitable for use in areas exposed to moderate bushfire risk.

It is a group of three closely related trees, \u003cem\u003eCorymbia maculata\u003c\/em\u003e, \u003cem\u003eC. citriodora\u003c\/em\u003e and \u003cem\u003eC. henryi\u003c\/em\u003e, cut from Queensland down to the NSW south coast. The boards run from pale brown to a dark red-brown, often in the same pack, with a wavy grain that shows the figure once it is oiled. At about 990 kg\/m³ seasoned it is heavy; a 5.4 m length of 135 × 19 weighs around 14 kg.\u003c\/p\u003e\n\u003cp\u003eWoodSolutions puts its seasoned hardness at 10.1 kN, above Blackbutt (8.9) and Merbau (8.5), and rates the heartwood durability Class 1 above ground and Class 2 in the ground, with natural termite resistance. It is also the lowest-bleed hardwood we sell: WoodSolutions describes it as less prone to tannin bleed than other species, so it is the safer pick next to pale paving or render. The sapwood can be attacked by lyctid borer, which is why decking is cut from heartwood.\u003c\/p\u003e\n\u003ch2\u003eWhere it suits\u003c\/h2\u003e\n\u003cp\u003eSpotted Gum is on the AS 3959 list of bushfire-resisting timbers, so at 19 mm it can be used for decking up to BAL-29 without any treatment; BAL-40 and Flame Zone need a tested system. That, the hardness and the low bleed make it the all-round choice: house decks, pool surrounds, steps and commercial outdoor areas. The one place we would steer you elsewhere is a deck that stays wet and shaded most of the year, where grey ironbark or Grey Box, both Class 1 in the ground as well, give more margin.\u003c\/p\u003e\n\u003ch2\u003eFixing and finishing\u003c\/h2\u003e\n\u003cp\u003ePre-drill every fixing: at this density screws will snap or split the board end otherwise. Use two stainless or Class 3 galvanised screws per board at each joist, 450 mm joist centres, and a 4–5 mm gap on the 135 mm board (3–4 mm on 86 mm).

With a Janka hardness of 11.0, it resists dents, holds up under heavy use, and stays stable once laid.
