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 Blackbutt flooring is like\u003c\/h2\u003e\n\u003cp\u003eBlackbutt, \u003cem\u003eEucalyptus pilularis\u003c\/em\u003e, comes from the NSW and southern Queensland coast and is the pale, straight-grained hardwood that suits most modern interiors: cream to pale honey brown, with a fine, even grain and far less colour swing from board to board than Spotted Gum. At about 900 kg\/m³ seasoned, with a WoodSolutions hardness of 8.9 kN, it is a proper hard floor without being difficult to cut or sand.\u003c\/p\u003e\n\u003cp\u003eIt takes a water-based coat well and stays pale under it; an oil-based polyurethane warms it to honey. The same species is on the AS 3959 bushfire-resisting timber list, which matters for decks and cladding rather than an interior floor.\u003c\/p\u003e\n\u003ch2\u003eGrades for this timber\u003c\/h2\u003e\n\u003cp\u003eSelect is the cleaner board, with few gum veins or knots and an even colour; Standard allows gum veins, small knots and more colour variation and costs about 20% less. Both are the same timber, kiln-dried and machined the same way. 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). Allow 5–10% extra for cuts and the odd board you set aside.
