1. Surface Area

Take a measurement of the surface to be painted. This can be in square metres or square feet, but keep a note of which. This includes all walls, doors, trims, windows, and other surfaces to be painted.

2. Type of Paint

The type of paint you choose will depend upon various factors such as your budget and the surface being painted. Exterior or interior, glossy or matte, textured paint - there are different types of paints available to choose from.

3. Coverage Rate Of Paint

Coverage rate of paint depends on the thickness or viscosity of the paint. Most paint buckets come with instructions printed that will help you determine the coverage rate per litre. This can help you estimate the amount of paint required.

4. Number Of Coats Required

Are you simply refreshing your walls or doing an all out paint job? This will help determine if you need one coat, two coats, or even more. This will further impact the amount of paint required.

5. Price Of The Paint

Paint is priced per litre, and is sold in different sized buckets. The cost per litre varies according to the type of paint and this information can be determined in store or on the manufacturer’s website.

6. Cost Of Labour

The cost of labour can depend on various factors such as your location, the skill of the labourer, do they work hourly/daily or on a project basis, and the complexity of your project. It is best to predetermine this so that there are no surprises in the future.

8. Cost Of Equipment

Painting the space involves some basic equipment such as rollers, brushes, tapes and cleaner liquids. The cost of such equipment should be accounted for when budgeting the cost of painting.

Once all this information has been gathered, you can calculate the cost of painting using the following paint calculation formula:

Painting Cost = (Surface Area to Be Covered / Coverage Area of Paint) x Number of Coats Required x Paint Price

Add to this Cost of Labour and Cost of Additional Material (if any)

It is important to note that this is a very basic and straightforward way of estimating the rough cost – the actual costs may differ. It is best to invite quotes from professionals to determine a more accurate cost.

Paint

Paint is usually a liquid substance that is used as a final coat on surfaces as a decorative and protective element. On average, 1 litre of paint can cover almost 100 sq. feet of paintable surface.

Putty

Putty is a paste prepared to fill in the gaps and minor dents in order to create a level surface. Often, a putty covered surface needs to be coated with a primer before you can paint it. The amount of putty depends on the surface area that is being painted.

Coverage Area

• Spray-painting a surface can cover more area than using a roller or a brush.
• To know the exact coverage area of your paint, refer to the manufacturer’s instructions – each paint bucket usually has the coverage area written on it.
