A Calculate the area of ​​paint

Formula one: Total brushing area converted from floor area

Algorithm: Total paint area = four walls painted + ceiling paint

Four-sided wall painting area = floor area multiplied by 2.5

Ceiling painting area = floor area

Therefore, the total painted area (including ceilings) = floor area times 3.5 (note: due to ceiling height and the number of doors and windows have increased or decreased)

Formula 2: Estimated paint volume for repainted walls = total painted area divided by unit area painted

For example, if the area to be painted is 10 square meters, the total painting area is 35 square meters, then the estimated amount of paint on the repainted wall is: 35 square meters divided by 3.5 (3.5 square meters per kilogram)=10. Therefore, the required paint weight is 10 kg. (Note: The actual amount of paint will increase or decrease depending on the condition of the wall and the method of painting.)

B Alternative methods for estimating paint usage

How many topcoats (calculated by 2 passes) are appropriate? More waste, less but not enough. There is also a simple calculation formula for reference: room total area (square meters) &spanide; 4 + wall painting height (meters) &spanide; 0.4, which is the number of kilograms of the required topcoat. For example, the total area of ​​the room is 16 square meters, the height of the wall painting is 1.6 meters, according to the formula above, you can buy 8 kg of topcoat. According to the experiment, it was enough to coat it twice, no more and no less, just right.
