Before painting, it is necessary to make some calculations on the painting area to roughly estimate how much paint is needed to avoid unnecessary waste.
When performing exterior wall painting, often a building has four sides to be painted, but due to the presence of doors and windows, we often do not need to brush the area of ​​all four walls, so as long as the area of ​​four walls minus the area of ​​doors and windows is We need to paint the actual area, in general, we will set the proportion of the total area of ​​doors and windows to 20% (the data accumulated by the actual experience of Shuanghu Decoration Engineering Co., Ltd. is for reference only), so the painting area of ​​the outer wall coating can be The estimate is (total area of ​​four walls × 0.8).
For interior wall painting, in a standard square room, in addition to the four sides that need to be painted, it also has a roof, so you need to brush five sides, and in this five sides, or more Or there are few doors and windows, so you also need to subtract the area of ​​doors and windows, namely: (Length × width + length × height × 2+ width × height × 2-doors and windows area), simplified: (Length × width + Perimeter × height - window area). Under normal circumstances, the results calculated by the above methods are all about 3.5 times of the floor area (the data accumulated by the actual experience of Shuanghu Decoration Engineering Company is for reference only), so it can be used in practical use (length × width × 3.5) To estimate the brushing area of ​​the interior wall.
