The 12 and 13 mm boards (85 × 12, 112 × 13 and 133 × 12) are overlay floors that must be glued or nailed to a continuous subfloor or direct-stuck to a slab over a moisture barrier. All are tongue-and-groove and end-matched, and all are sanded and coated after laying.\u003c\/p\u003e\n\u003ch2\u003eWhat Tasmanian Oak flooring is like\u003c\/h2\u003e\n\u003cp\u003eTasmanian Oak is not one tree but three sold together: alpine ash (\u003cem\u003eEucalyptus delegatensis\u003c\/em\u003e), mountain ash (\u003cem\u003eE. regnans\u003c\/em\u003e) and messmate (\u003cem\u003eE. obliqua\u003c\/em\u003e), cut in Tasmania and Victoria. The boards are pale, from straw through cream and pink to a light reddish brown, with a straight, even grain and almost no gum vein in Prime grade, which is why it is the floor people choose when they want the room to feel light.\u003c\/p\u003e\n\u003cp\u003eIt is the softest floor on this list, with a seasoned hardness of 4.9 kN in the WoodSolutions table (Tasmanian Timber quotes 5.5), at about 650 kg\/m³, so it marks more easily than Blackbutt or Spotted Gum under stiletto heels and dragged chairs. In exchange it is the most stable: unit movement of 0.23% radial and 0.36% tangential per 1% change in moisture, which is why wide boards and underfloor heating are usually done in Tasmanian Oak. It takes stains and clear coats evenly and sands cleanly.\u003c\/p\u003e\n\u003ch2\u003eGrades for this timber\u003c\/h2\u003e\n\u003cp\u003eOur Tasmanian Oak is Prime grade, the cleanest grade: few gum veins, knots or marks, and an even colour across the pack. It is the grade to use when the floor is meant to read as one pale surface. 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.
