Analysis & guidance

  • Method

    Calculate net requirements, waste allowance and whole packages. Paint: area times coats divided by product coverage. Flooring: area. Concrete: area times depth in metres.

  • Example

    An area of 5 × 4 m, two coats and 10 m²/l needs 4 litres of paint. With 10% waste it needs 4.4 litres. Three-litre tins mean two tins, 6 litres purchased and 1.6 litres left after waste.

  • Limitations

    Enter the product’s stated coverage and package size. Units are litres for paint, m² for flooring and m³ for concrete. Set waste in advanced options. Surface and technique affect actual usage. This tool does not design load-bearing structures.
