For example, if you are living in a house with a living space of 100 m², the ceiling area is calculated as 100 x 0.85 = 85 m² and the wall area is calculated as 100 x 2.2 = 220 m². Based on these figures, you can determine the amount of paint you will need by looking at the consumption values per square meter given on the label of the paint you selected.
In paint consumption, the condition of the surface and the number of coats will affect the amount of paint that will be needed.
