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 Grey Ironbark flooring is like\u003c\/h2\u003e\n\u003cp\u003eGrey ironbark, mainly \u003cem\u003eEucalyptus paniculata\u003c\/em\u003e, is the hardest and heaviest floor we sell: WoodSolutions gives a seasoned hardness of 16 kN at about 1,106 kg\/m³, roughly double Merbau and well above Spotted Gum. The boards run light grey to light chocolate with darker red and brown pieces, a tight interlocked grain, and very little figure, so the floor reads as dense and even rather than lively.\u003c\/p\u003e\n\u003cp\u003eIt is the floor for shops, halls and houses with dogs, dragged furniture and hard use. The heartwood is naturally termite resistant and the sapwood is not susceptible to lyctid borer. The trade-off is in the laying: it is heavy, blunts blades, and needs sharp tooling to cut cleanly.\u003c\/p\u003e\n\u003ch2\u003eGrades for this timber\u003c\/h2\u003e\n\u003cp\u003eFeature grade, the one we stock, shows the full colour range with gum veins and some knots; Standard and Select are progressively cleaner and are ordered in. In ironbark even Feature grade looks even, because the grain is so tight. Grade names vary between suppliers, so ask what each one allows; our \u003ca href=\"\/blogs\/guides\/timber-grades-explained\"\u003etimber grades guide\u003c\/a\u003e explains the system.\u003c\/p\u003e\n\u003ch2\u003eLaying and finishing\u003c\/h2\u003e\n\u003cp\u003eBoards are supplied kiln-dried at 10–12.5% moisture content. If that matches the house, lay them; if the house is noticeably wetter or drier, open the packs and stack them with airflow for a week first. 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).
