How The Calculation Works
Formulas, material coverage assumptions, waste buffers, and rounding standards.
Paint is calculated in litres, with coverage stated per litre per coat — Indian emulsion typically covers 10-12m² (110-130 sq ft) per litre depending on surface porosity.
Indian walls are usually cement plaster finished with wall putty rather than gypsum plaster, and putty consumption is estimated separately because it materially affects paint coverage.
Tins are sold in 1L, 4L, 10L and 20L, so quantities round to those sizes rather than to gallons.
