Thinking of repainting your home? There are certain factors you must determine before you buy paint and start the job-and one of these factors is the right amount of paint. It’s important to take time to calculate for the amount you need to prevent waste or the hassle of running out of paint in the middle of a job. Here are some quick and simple steps to calculate how much paint you’ll need for your project:

- Measure the room – Measure all the walls that will be painted so you can figure out the average amount you need for one coat of paint. To begin with, measure the room’s surface area, measuring from floor to ceiling and from wall to wall (discounting the floor and ceiling). The total of the width of the walls must be multiplied by the height of the room so you can determine the surface area in square metres.

When determining the surface area, don’t include the doors and windows in the total. Once you have the total size in square metres, subtract approximately 1.85 square metres for the doors. Measure the windows to determine their size and remove that number from the total to find the surface area of the room.

- Determine the number of coats you will make – An average four-litre bucket should be able to cover roughly 32 square metres of wall with a single coat. Before you buy paint, think about the number of coats you want to make and the type and viscosity of paint you intend to use.
- Do not forget the primer – A primer will help the actual paint stick longer to the wall and appear more vibrant in the long run. Calculate the number of primer coats you will need for every room.
- Consider using a paint calculator – You can minimise the guesswork by using an online paint calculator.
- Hire experts – Save yourself from the trouble of having to do all the numbers and the painting yourself by hiring professional painters and decorators. This is the best way to ensure that job will be accomplished quickly and efficiently-and that you never have to worry about cleaning up on your own.
