Paint latex paint usage calculation method

Coating latex paint is basically divided into 5 liters and 15 liters of two specifications. Taking the 5 liters capacity commonly used in households as an example, the theoretical brushing area of ​​5 liters is 35 square meters twice.

A rough calculation method: ground area × 2.5 ÷ 35 = number of barrels used.

Accurate calculation method: (length + width) × 2 × room height = wall area. Length × width = top surface area (wall area + top surface area - door and window area) ÷ 35 = number of barrels used.

Taking a room with a length of 5 meters, a width of 3 meters and a height of 2.9 meters as an example, the indoor wall and top brush area are calculated as follows:

Wall area: (5 meters + 3 meters) × 2 × 2.9 meters = 46.4 square meters

Top area: (5 meters x 3 meters) = 15 square meters

Coating amount: (46.4+15) ÷ 35 square meters = 1.7 barrels
