Oil Finish Calculator — Danish Oil, Tung Oil & Linseed
Estimate oil quantities for Danish oil, tung oil, and linseed oil wood finishes.
How We Calculate This
Litres = [ Area × (1 + first-coat boost) ÷ rate + Area × (coats − 1) ÷ rate ] × (1 + waste), rounded up to the nearest 0.1 L.
The raw first coat soaks into dry timber, so it uses extra oil (default +25%); later coats apply at the normal rate. A waste allowance (default +10%) covers spills and touch-ups. Coverage: Danish Oil ~16 m²/L, Tung Oil ~12 m²/L, Linseed Oil ~18 m²/L, Hard Wax Oil ~14 m²/L per coat on smooth sanded interior timber.
Example: 10 m², 3 coats of Danish oil (16 m²/L), +25% first-coat boost, +10% waste → (10 × 1.25 ÷ 16) + (10 × 2 ÷ 16) = 0.78 + 1.25 = 2.03 L, × 1.10 = 2.23 L, rounded up to 2.3 L.
