YOGYAKARTA Calculating the need for wall paint needs to be done so that the need for paint is not lacking or more when buying home paint. How to calculate the need for wall paint is done by utilizing the mathematical formula, namely looking for the area of the wall and the distribution of paint. For more details, see the following article.
The step to calculate the needs of paint is carried out with several stages. In order for the results to be precise, follow the following calculation steps.
The first step that must be taken is to calculate the surface area of the wall to be painted. To find the area, you need a meter to measure the height and width of the side. After that, use the Widest (m2) = Tinggi (m) x Lebar (m) formula.
For example, you plan to paint a wall covering an area of 4 x 5 meters. Thus the area of the wall is 20 m2 (square meter). Adjust also to how many sides of the wall you want to paint.
If the wall has doors, windows, ventilation, or anything that does not include a paint object, you also need to look for its area so as not to count the area of the wall. This area can be calculated with the same formula, namely (m2) = Tinggi (m) x Lebar (m).
For example, you plan to paint a wall with a door. You need to calculate the area of the door so that the paint needs can be calculated accurately.
This step is necessary to eliminate the area of the wall after deducting the door area. For example, you plan to paint a wall covering an area of 20 m2, but the installed door is not painted. The door has an area of 2 m2. That way you can calculate it with the Wall Area formula The Door area, which is 20 m2 - 2 m2 = 18 m2.
Each paint has a different spread power, depending on many things, including the thickness. Generally, 1 liter of paint can be used to paint at least 10 m2 (1 layer). This means that if you buy a 5 liter paint, the paint can be used to paint a 50 m2 wall.
At this stage, you can use a formula for the area of the wall that is painted / paint propagating with a stratum of 18 m2 / 10 m2 = 1.8 (liter). Thus, the need for paint for a wall with an area of m2 with 1 layer of paint is 1.8 liters. If you don't know how long the wall paint lives, and you want a longer color, it is recommended to paint as much as 2 layers.
