The type of finish that you decide to select will make a slight difference to the overall cost of the project. For the most part, the selected finish is one of personal taste. However the table above will provide you with some of the pro’s and con’s of each finish. In some cases, it is more practical to use different finishes in different rooms. When consulting with you at your premises, we will be able to provide guidance.

For purposes of simplicity, we have provided you with three choices ranging from matt, to medium sheen /satin or to a high-gloss finish.

Grab a friend to help measure the width and height of walls with a metal tape measure and multiply these together to calculate the overall square metre measurement.

Let’s use an example of how to measure a single room.

First, measure the total distance (perimeter) around the room: (3.5m + 4m) x 2 = 15m

This will be the same number that you will use for linear meters of skirting against the walls.

Then, multiply the perimeter number (eg. 15m) by the ceiling height to get the total wall area: 2.3m x 15m = 34.5m² (2.3m is a standard height of most recently built homes).

If you would like a more accurate measurement, you can provide for doors and windows. On average, you can allow around 2m² for each door (let’s assume two for this example): 2m² x 2 = 4m² and windows can vary in size, but assume an average of 1m² a window. We can assume that there are two in this example, so: 1m² x 2 = 2m²

So, now you take the total wall area and subtract the area for the doors and windows to get the wall surface to be painted: 34.5m² (wall area) – 4m² (doors) – 2m² (windows) = 28.5m²

Do this for every internal room and add all of the measurements together to get the total vertical square meters.

- This means that the total wall area to be coated for this room in the example is 28.5m² – keep adding the results to for each room, until you have the total area in square meters of the interior (it is not necessary to deduct for windows and doors as we have made allowance in the system). Use the slider to enter the result in the quote system.

The next step is to select your finish for your ceiling and your cornices. We generally recommend using the same finish, although sometimes wooden cornices last better with a gloss or enamel finish, such as Plascon Velgaglo (option 4).

From this you can calculate the area of the ceiling by multiplying the width by the length: 3.5m x 4m = 14m²

Do this for every room and add the total area of the ceilings together. Our quotes allow for caulking and painting of the cornices as well, so simply input the total area of ceilings using the slider.

Decide whether or not the doors require painting, and if so whether you will just be doing the door frames, or the entire doors and frames.
