Recently, consumers have reported that many paint workers in order to eat business rebates, introducing the paint brand is secondary, and even more estimates the amount of wall paint, causing unnecessary waste and deceiving consumers. In view of the appeal situation, today's Xiaobian provides professional estimation methods to prevent being deceived or wasted in the future.
The most common application in the family belongs to latex paint. The calculation method for the amount of latex paint is introduced below:
First of all, it is necessary to clarify the concept of the use area of ​​houses. The average residential building use area is 85% of the building area of ​​the house. In the residential decoration, the total surface area of ​​the wall and the ceiling is 3 to 3.5 times the area of ​​the house. Said, a wall painting area = (building area * 85% - kitchen, bathroom floor area) * (3 ~ 3.5). Knowing the area that needs to be painted, what is the next step?
Next, the amount of latex paint is calculated. Generally 1 kilogram of latex paint can be counted as 10 square meters of wall. In other words, 1/10 kg of latex paint is needed per square meter of wall.
The amount of paint used in general wall paint (L, L) = wall painting area * single pass theoretical coating rate (m2 / liter). (General household rough room is painted 2-3 times)
Paint amount on the wall (barrel) = paint amount on the wall paint (L, L) / number of drums.
Case Study: Take a house with a floor area of ​​120 square meters. The kitchen floor area is 30 square meters:
Wall painting area = (120 * 85% - 30) * 3.2 = 230 square meters (about)
Paint for wall paint = 230 square meters * 1/10 kg = 23 kg
(Note: It is necessary to read the detailed instructions for the purchase of latex paint. Whether the high concentration needs to be used with water, or it can be used directly)
In summary, the calculation of general paints is to estimate the quantity, and the results will not get an integer bucket. Generally, the number of barrels is calculated by rounding off. Calculating the amount of household paint is very complicated, but as long as you master the skills, according to the formula provided by China's new paint network, I believe that you will be better estimated in daily home decoration, no waste and deception in the decoration.
