How to calculate the large white area of a residential building

Perimeter of the room * clear height of the room - projected area of door and window openings.

It just needs to be shaved white.

area. The side area of the door and window openings is not added, and the baseboard is not reduced.

The area occupied and the area of small openings that are less than squared.

Bathrooms and kitchens do not need to be counted, because bathrooms and kitchens need to be tiled, so this cannot be counted. It is best to refer to the field measurements at the site.

There is also a rough calculation method, multiply the room area by 3 or, the amount of materials calculated in this way is basically reasonable, but if it is to calculate the cost of painting the wall, this calculation is obviously not reasonable, because each house is different, and the wall area is different.

For example, the living room, which is the circumference of the living room x the height of the entire lift. Doorways and windows are basically calculated by subtracting half of the width of the door and window x the height of the entire lifting frame. The area of the top surface is basically the usable area of the residential building, and then subtract the area of the aluminum gusset ceiling in the bathroom and kitchen.

And there is also a general calculation method for the entire area of the big white, that is, the construction area x3It should be noted that if the decoration company proposes to scrape the plaster on the wall, then the top surface does not need to scrape the plaster, so don't spend unjust money.

AbstractThe white places in the city are the roof and the wall, and the house can be approximated as a cube, so the surface area of the house other than the ground can be roughly calculated according to the dimensions of the house.

Take a house of 3 3 meters and a height of 3 meters as an example, the area of scraped white is: 3 3 + 3 3 4 = 45 square meters.

How to calculate the area of indoor scraping, (how many squares)?

The roofs and walls of the houses in the city can be approximated as cubes, so the surface area of the house other than the ground can be calculated according to the dimensions of the house. Take a house of 3 3 meters and a height of 3 meters as an example, the area of scraped white is: 3 3 + 3 3 4 = 45 square meters.

The house is 110 square meters, that's how much area.

You have to look at how much higher.

How wide is it?

There are three ways to calculate the large white area, one is to calculate the area of the wall first, and then multiply the area of the wall by multiplying it. The second is to calculate the area of the wall, including doors, windows, and heating covers. The third is calculated based on multiples of the ground area.

When decorating the room, scraping white has become an indispensable step in indoor wall decoration, and it is also a very important environment. So how to calculate the large white area of the staircase? Let's take a look at it below, I believe it will bring you different insights.

There are two ways to calculate the white area of the staircase, one is to calculate according to the actual scope, and the area of the door and window is not deducted from the communication; The other is calculated according to the floor area. For the amount of paint, the thickness of the primer is mainly 30 microns, and the recommended thickness of the topcoat is 60 to 70 microns; So the amount of primer = construction area 70; Amount of topcoat = construction area 35.

What are the precautions for staircase scraping.

1. The construction wall must be kept dry, the surface moisture must be less than 6%, and the pH value should be lower than 9; At the same time, the construction of new cement generally requires maintenance for 20 to 40 days; The detection method can be touched by hand, if there is no sense of moisture, there is no watermark on visual inspection, it means that it has passed.

2. Before construction, the front bulge should be removed, and at the same time, oil, dust, mildew and loose areas should be removed; In addition, when dehumidifying, you can rinse with dilute acid water, then rinse with clean water, and then brush the paint after drying; When removing mold, first use a shovel blade to remove the mold on the construction surface, and then use wall washing water, spray twice, and wait for drying, before brushing the paint.

3. During construction, it is recommended to add a small amount of water for dilution according to the different weather and painting methods; And when the temperature is lower than 7 °C and the humidity is higher than 85%, it is not suitable for construction; Do not apply when the temperature is lower than 7 °C and the humidity is higher than 85%, and in order to make the paint film durable, color retained, and not harmed by alkaline substances in the wall, use a sealing primer as a primer.

Summary: Well, the above is about the content of how to calculate the large white area of the stairs to introduce Paihu, I hope to provide you with some help, I believe that in the future in the process of understanding how to calculate the large white area of the stairs, friends will be more handy, get their own satisfactory answers.
