Jak vypočítat Paint
Co je Paint?
A paint calculator estimates the number of litres needed to cover walls and ceilings based on room dimensions and paint coverage rates. Most standard emulsions cover 10–14m² per litre; masonry and exterior paints typically cover less (8–10m² per litre).
Průvodce krok za krokem
- 1Calculate wall area: add all wall surfaces (length × height for each wall)
- 2Subtract doors (~2m²) and windows (~1.5m²) from the total
- 3Divide by coverage rate (m² per litre) for the paint type
- 4Multiply by number of coats (typically 2 for fresh colour, 1 for same colour)
