For home decoration paint, due to the large use area and wide application range, the amount of home decoration paint directly affects the amount of home decoration budget. Therefore, when carrying out the home decoration budget, the reasonable calculation of the amount of home decoration paint is the premise of making the home decoration budget and one aspect of saving the budget. Before calculating the amount of home paint, you need to know the following aspects:

I. calculation formula of household paint consumption

1. Calculation formula for construction area of wall paint: construction area of wall paint = (construction area × 80% - floor area of kitchen and toilet) * (3 ~ 3.5)

2. Calculation formula of the amount of wall primer: construction area ÷ 70

3. Calculation formula of wall finish: construction area ÷ 35

II. Calculation method of wall paint consumption

For wall painting construction, the amount of paint is directly related to the area of the wall. In the above formula, we can see. Therefore, we need to know the wall area before calculating the amount of paint

When painting the wall, not all the paint is used in the kitchen and bathroom, especially the floor of the kitchen and bathroom. It is recommended to lay ceramic tiles, so this part needs to be removed during calculation. And the ceiling, ceiling, etc. in the house decoration, the painting area is about 3-3.5 times of the use area of the house, so this part needs to be added in the calculation

III. Calculation Method of amount of wall primer

For the paint, in the home decoration, the painting process is more complex, more painting needs to be painted many times. For the wall primer, according to the modern house painting construction standard, the thickness of the primer needs 30 microns

Professional construction personnel usually brush primer several times, and experience tells them that the construction area of 5-litre primer is about 60-70 square meters, so the calculation method of the amount of wall primer is construction area ÷ 70

IV. painting calculation of doors and windows

When decorating and painting, they pay by square meters. After calculating the amount of paint, many families have a general understanding of the painting area in the family, and can know the budget of painting construction

However, in many cases, due to the fact that the area of the door and window is not considered by the residents, the cost of painting is different, because the construction technology of this part is difficult and requires additional charges. Therefore, when considering the amount of paint, the residents need to calculate the amount of this part

For the calculation of paint consumption, it is necessary to conduct field measurement with the decoration company, and calculate the budget in combination with the paint price, consumption and additional door and window paint cost. The price shall be agreed with the decoration personnel in advance to avoid decoration disputes
