Fire & Finish — Intumescent DFT & Litres
Intumescent DFT & Litres for steel fire protection and finishing.
Intumescent is fire protection sold by the micron — 1,200 µm is twelve coats of ordinary paint, applied in 2–4 passes with film-gauge checks at every column. It exists for steel the architect wants SEEN; the per-litre price makes the SFRM alternative's ugliness look affordable.
Formula
Note: Erection-planning estimate only. Member weights, connection capacities and tolerances for execution must come from the issued drawings, the EOR and the erection engineer — never from a generic calculator.

About Fire & Finish — Intumescent DFT & Litres
Fire & Finish — Intumescent DFT & Litres computes the governing relationship L = A×DFT/(10×solids) × (1+loss) live as you type. Intumescent is fire protection sold by the micron — 1,200 µm is twelve coats of ordinary paint, applied in 2–4 passes with film-gauge checks at every column. It exists for steel the architect wants SEEN; the per-litre price makes the SFRM alternative's ugliness look affordable. Defaults are pre-filled with realistic values for this exact scenario, and the worked example substitutes your numbers step by step so the math is never a black box.
How to use Fire & Finish — Intumescent DFT & Litres
- 1Enter your values — AESS steel area, Required DFT, Volume solids, Application loss (sensible defaults are pre-filled).
- 2Read the live results: Paint required.
- 3Check the "with your numbers" line to see L = A×DFT/(10×solids) × (1+loss) substituted step by step.
- 4Adjust inputs until the scenario matches yours, then copy or share the result.
