Paint Amount

[SPP]

I got the following dimensions for the area I need to paint: 

1) Ceiling Area: 50 sqm 
2) Wall Area: 68 sqm

The ceiling is plasterboard, the walls are VJ. 

I have attached photos of what paint I am using for walls and ceiling. How do I calculate how much paint I need and how much this will cost? 

Ceiling Plan: 
1) One Coat of Primer
2) One or Two coats of Ceiling Whit

Walls: 
1) Two coats of wall paint (VJ is already primed!) 




Also, been preparing the VJ by sandpapering places where I had to use Gap Filler. See below. Some of the bare wood is exposed. Do I need to go over this with Primer?

Hi @SPP,

According to Taubmans website, Taubmans Ceiling White Interior Paint has a coverage rate of up to 16m2/litre and Taubmans Endure Interior Paint has a coverage rate of up to 12m2/litre.

As your ceiling area is 50 square meters and you'll need two coats, we should treat it as 100 square metres, meaning you would need 6.25L if you absolutely maximise its coverage. Your best option would be to grab 2 x 4L Taubmans Ceiling Brilliant White, at a cost of $125.80.

Again, your walls would need two coats, so you'd need 136 square metres. With the coverage rate of 12m2/litre, you would need 11.33L if you maximised coverage. Your best option would be to grab a Taubmans 15L White Low Sheen Endure Interior Walls Paint at a cost of $249.00.

For primer, you would follow the same process of checking the manufacturer's website for the coverage rate, then compare that coverage rate with how much area you need to cover to work out how much you'll need.

With the areas that were sanded and filled, it would definitely be worthwhile applying a coat of primer.

Let me know if you have any further questions.
