Zhongshan hardware paint latest consumption calculation method

method 1:

rough calculation method: ground area × 3 ÷ theoretical painting area of glue paint is twice = accurate calculation method of the number of barrels used: (wall area + ceiling area - door and window area) ÷ theoretical painting area of glue paint is twice = number of barrels used note: (room length + room width) × two × Room height = wall area (including door and window area)

simple calculation of glue paint bubble bag recycling cost very high coating amount: room area (square meters)/4+ wall height (decimeters)/4 = required glue paint coating kilograms (kg) Note: it can be brushed twice, and 6kg glue paint coating is equivalent to 5L method 2:

calculation formula of hardware painting construction area: wall paint construction area = (building area × 80%-10) × 3. The building area is the area of house purchase. The current actual utilization rate is generally about 80%. The kitchen and bathroom are generally made of ceramic tiles and aluminum gusset plates.

the area of this part is mostly 10 square meters. The area obtained by this calculation method includes the ceiling. The ceiling does not have a great impact on the construction area of hardware paint, so it can be ignored (the result obtained by this formula may be the closest to the actual area)

paint consumption: according to the requirements of standard construction procedures, the thickness of ul1005 primer is 30 microns, and the construction area of 5-liter primer is generally 65 ~ 70 square meters; The recommended thickness of finish coat is 60 ~ 70 microns, and the construction area of 5 liters of finish coat is generally 30 ~ 35 square meters

primer dosage (5l/barrel) = construction area ÷ 70; Dosage of finish paint (5l/barrel) = construction area ÷ 35:

18 liters. The construction area of primer is generally 250 square meters; The construction area of 18 liters of finish paint is generally 125 square meters

primer dosage (18l/barrel) = construction area ÷ 250 finish coat dosage (18l/barrel) = construction area ÷ 125 note: for paint construction, one coat of primer and two coats of finish coat

for example, for a room with a building area of 120 square meters, the amount of paint required (take 5L installation as an example):

wall paint construction area = (120 × 80%-10) × 3=258 square meters primer dosage = construction area ÷ 70=258/70=3.7 (barrels), that is, 4 barrels of finish paint dosage = construction area ÷ 35=258/35=7.7 (barrels), that is, 8 barrels can be calculated. The paint consumption in 18L:

primer dosage =3.7 × 5/18=1.02 (barrel)

amount of finish coat =7.7x5/18=2.13 to ensure the accuracy of measurement data; (barrel)
