Paint coverage in India
Emulsion for interior walls typically covers 120–160 sq ft per litre per coat depending on surface porosity. Two coats are standard on new plaster; one coat may suffice on repaints with compatible primer. Ceiling area can be included separately in the tool.
Tile wastage
Use 8% for simple rectangular rooms, 10% for L-shaped layouts, and 15% for diagonal layouts or large-format tiles. Buy tiles from one batch/lot to avoid shade variation.
