Paint, primer and putty calculator.
Estimate paintable area, two-coat paint, primer and putty after subtracting openings.
Paint, primer and putty inputs
Use the actual product data sheet for coverage. Surface condition, texture, colour change and application method can materially change consumption.
Method: Net paintable area equals wall area minus openings. Paint and primer divide by separate entered coverage rates; paint multiplies by coat count.
Inputs used: Gross wall area = 1,000 sq ft; Doors and windows = 100 sq ft; Paint coats = 2 coats; Paint coverage = 100 sq ft/L; Primer coverage = 120 sq ft/L; Putty consumption = 0.03 kg/sq ft
Assumptions: Site and equipment inputs are planning assumptions supplied by the user or displayed by the calculator.
Scope and warnings: Use the actual product data sheet for coverage. Surface condition, texture, colour change and application method can materially change consumption. Obtain site-specific engineering and equipment checks before purchase or installation.
How this paint, primer and putty calculator works
Net paintable area equals wall area minus openings. Paint and primer divide by separate entered coverage rates; paint multiplies by coat count.
A worked example
For 1,000 sq ft net area, two coats at 100 sq ft/L need 20 L before touch-up allowance.
Why should coverage remain editable?
Surface porosity, texture, colour, product data sheet and application method change coverage.
Calculations run on your device. Review your results before exporting or sharing them.
Use the product data sheet
Coverage is not a universal number. Enter the manufacturer coverage for the surface and coating system, then use the calculated litres as an order screen.
Two coats can improve finish but do not solve dampness, surface failure or preparation. Include primer and putty only where the selected system calls for them.
