What you get
Calculate paintable area, litres and tins from coverage and number of coats.
How to use it
Enter only the requested values and check the unit shown beside each field. The main result gives the figure to use first. Details explain conversions, secondary quantities and rounding. Change any value to compare another situation without starting again.
Before using the result
Measure the finished area and use the coverage or pack size stated on the product you will buy. An allowance helps cover cuts and waste, but does not replace the manufacturer’s instructions.
