The wall area should be calculated for wall painting, so how to calculate the area of wall painting

House decoration to the last process of painting, in the current high wages of workers, of course, they have to calculate the painting area, so as not to be fooled by the decorators, then the problem comes, many novices for the first time decoration, do not understand how to calculate these areas, and do not know what the industry regulations are, so now let's find out.

Wall painting is calculated by multiplying the perimeter of all your rooms, multiplying by the floor height, minus the area of doors and windows, plus the area of the roofThis is calculated to be the area of painting, the price per square meter is very different due to the difference in each region, it is recommended to know more about a few more to make comparisons.

Now some decoration companies do not deduct doors and windows when calculating the paint area, and the industry regulations generally deduct half of the area where there are doors and windows, which is also determined according to the local situation, because some of the corners of the door holes are also to be painted and painted, so it will also be counted as an area.

In the actual construction process, or when making a budget, we will not calculate so carefully, and there is a rough way to calculate the area of wall painting in the industryWall paint construction area = (building area * 80% - 10) * 3The construction area here is the area you buy, the reason why you want to multiply it by 80% is because the actual utilization rate of the house is only about 80%, minus 10 square meters, mainly the bathroom, the kitchen wall with tiles, about 10 square meters, although the result of the calculation is not very accurate, but the impact on the overall construction area is not large, the general workers do the budget, the paint shop calculates the paint, and also uses this formula.

After knowing the construction area of wall paint, you can calculate the amount of primer and topcoat, there is also a formula, taking the construction area is 120 square meters as an example, according to the above formula can be calculated that the wall construction area is 258 square meters, according to the standard construction degree, the thickness of the primer is 30 microns, 5 liters of primer can generally be constructed 65-70 square meters, the thickness of the topcoat is generally 60-70 microns, and 5 liters of topcoat can be constructed about 30-35 square metersPrimer amount = construction area 80 (coating rate 1 pass) = 258 80 = barrels), i.e. 4 barrels

Topcoat dosage = construction area 45 (coating rate 2 times) = 258 45 = barrels), i.e. 6 barrels

The most important thing is to calculate the length, width and height, and then finally calculate the result, and the final result is the area of the entire wall.

Generally, it will be judged according to the roughness of the wall, and the paint will be used less if the wall is flat, and the thickness of the paint will be painted, and the actual area of the wall will generally be calculated according to the overall area.

The area of the wall should be calculated before the wall is painted, and the wall should be measured before painting, and the size, length and width occupy how many square meters.

The area of the room (square meters) is divided by 4, and the height of the wall to be painted (in decimeters) is divided by 4, and the number of the two is added together to give the kilogram of paint required.

For example, if a room is 20 square meters in size and the wall height is 16 decimeters (except for the 12 decimeter wall skirting), then it takes 9 kg of paint to paint the wall twice.

The area of the wall painted: The length of the wall multiplied by the height from the floor to the top, minus the area of the door and window openings or the projected area of the closet. The formula for calculating the construction area of wall painting: wall paint construction area = (construction area 80%-10) 3.

The construction area is the purchase area, the actual utilization rate is generally about 80%, the kitchen, bathroom is generally made of ceramic tiles, aluminum buckle plate, this part of the area is mostly 10 square meters.

The area derived by this calculation method includes the ceiling, and the ceiling does not have a great impact on the construction area of the wall paint and can be disregarded (the result obtained by this formula may be the closest to the actual area).

Paint consumption: According to the requirements of the standard construction procedure, the thickness of the primer is 30 microns, and the construction area of 5 liters of primer is generally 65 70 square meters;

The recommended thickness of the topcoat is 60 70 microns, and the construction area of 5 liters of topcoat is generally 30 35 square meters. Primer amount = construction area 70;Amount of topcoat = construction area 35.

The budget formula for decorating latex paint walls is calculated like this, and the construction area of wall paint is equal to (construction area 80%-10 3, which is the area of the house we are buying. At present, the usable area ratio is generally around 80%. The kitchen and bathroom are generally made of tiles and aluminum gussets, and the area of this part is about 10 square meters.

The top surface calculation method is length and width, if there is a stacked ceiling, then also need to add the stacked perimeter stacking height, the wall is the perimeter height, deduct the door and window area, plus the door and window side perimeter width.

Don't know how big your house is? For an accurate value, take a room as an example, with five walls (the perimeter of the floor or top multiplied by the height of the room plus the area of the floor or top surface minus the area that is not painted, such as doors and windows).

The formula for calculating the construction area of wall painting: wall paint construction area = (construction area 80%-10) 3.

The construction area is the purchase area, the actual utilization rate is generally about 80%, the kitchen, bathroom is generally made of ceramic tiles, aluminum buckle plate, the area of this part is mostly 10 square meters, the area obtained by the calculation method includes the ceiling, the ceiling has a very small impact on the construction area of the wall paint, can not be considered (the result obtained by this formula may be the closest to the actual area).

Paint consumption: According to the requirements of the standard construction procedure, the thickness of the primer is 30 microns, and the construction area of 5 liters of primer is generally 65 70 square meters; The recommended thickness of the topcoat is 60 70 microns, and the construction area of 5 liters of topcoat is generally 30 35 square meters. Primer amount = construction area 70;Amount of topcoat = construction area 35.

The projection area of the wall, the area of the closet is calculated, and the amount of brush is calculated.

As long as the house is made of red brick and concrete, the walls will definitely be used when decoratingPaintto make your home look neat, clean and bright. However, the area of the wall must be calculated for wall painting, otherwise how much paint to buy and how to calculate the price to the workers do not know. Next, we will share with you the calculation method of wall painting area.

Formula for calculating the area of wall painting:

Wall paint construction area = (building area * 80% - 10) * 3

The construction area is the area that everyone knows about buying a house, and the actual utilization rate of the general house is about 80%. The kitchen and bathroom at home are generally made of ceramic tiles and aluminum gusset materials, and the area of this part is mostly about 10 square meters, plus the ceiling has little impact on the area of wall paint construction, so the result obtained by the above calculation method may be the closest to the actual area.

Paint consumption: According to the standard construction procedures, the thickness of the primer is generally 30 microns, and the construction area of 5 liters of primer is generally 65 70 square meters; The recommended thickness of the topcoat is 60 70 microns, and the construction area of 5 liters of topcoat is generally 30 35 square meters.

To sum up: the amount of primer = construction area 70

Topcoat dosage = construction area 35

Note: Many owners are accustomed to deducting the area of doors and windows when calculating the construction area of wall painting, but it is understood that painters are generally charged by square meters, whether it is a decoration company or a painter, the area of doors and windows is generally not removed when painting wall paint. Some will be charged because of the high technical difficulty of painting doors and windows, but the charging standard is not uniform, it is recommended that the owner should negotiate the price with the construction team when painting the wall paint, so as not to cause disputes afterwards.

The wall painting area is introduced to you here, I hope we can help you! Although the decoration supervision will calculate the construction area during the general decoration, the owners themselves can also know a little more about the elderly.

When it comes to retrofitting, you first need to understand the scope of the retrofit. In this way, the required materials can be calculated at the time of renovation, the construction area is fixed, and it is clear when buying a residence, but the wall area is different, and how to calculate the wall areaThe area of the wall is paintedAnd how much? Let's take a look at itThe area of the wall is paintedimportant calculation formulas.

The area of the wall is painted=(Floor area 80%-10) 3 The construction area is the purchase area, and the actual utilization rate is generally about 80%. Kitchens and bathrooms are generally made of ceramic tiles and aluminum gussets, most of which are 10 square meters, including the area in the calculation method, and the ceiling has a large impact on the engineering area and is not considered (not the actual area of the result of this formula is near).

2. Regarding the amount of wall paint used: according to the requirements of standard engineering procedures, the thickness of the primer is 30 microns, and the project area of 5 liters of primer is generally 65 70 square meters;

The recommended thickness of wall paint is 60 70 microns, and the construction area of 5 liters of wall paint is generally 30 35 square meters.

3. The amount of base material used = construction area 70; The amount of topcoat used = construction area 35.

A house with a floor area of 120 square meters requires the use of paint.

Wall paint area = (120 80% 10) 3 = 258 square meters.

The amount of use at the bottom = 80 of the engineering area (coating rate of 1 time) = 258 80 = barrels), that is, 4 barrels.

The amount of topcoat used = the engineering area 45 (coating rate 2 times) = 258 45 = 5. Seven (barrels) is six barrels.

1. Then calculate firstThe area of the wall is painted, if anyThe area of the wall is paintedThe necessary amount of paint can be obtained by removing the coating area according to the coating area of 1L of paint. Regarding the general interior wall painting, it is calculated that the amount of paint required for 1 layer of painting = (floor area x 2 5) per liter of wall painting area.

2. For example, a new home of 80 square meters in a hall, the wall painting area of the new home is about 200 square meters, each liter can be painted with 5-in-1 paint 13-16 square meters, and each barrel of 5 liters of paint can be painted with 5-in-1 paint about 40 square meters of wall 2 layers, and the painting of this room includes a total of 500 million barrels of 5-liter 1 latex paint in this room.

The above is - how to calculate the area of the wall that brings you stuffy, as wellThe wall is painted with acresThe introduction of important calculation formulas, after reading it, you will definitely believe that there is a lot of knowledge and understanding of wall wall and interior decoration, and the big project of wall decoration, there is a little bit of bad place that is too eye-catching, so you must decorate it well.

Calculation method of wall painting area？After buying a house, start to decorate, there are many items about decoration, wall decoration can be said to be very important, and the decoration of the wall must be to paint the wall, then calculate the area of the wall in advance, and then buy the required materials, with the chainWhat is the calculation method of wall painting area?？Only by budgeting well in advance can you buy more suitable materials, so as not to cause too much waste.

1. The area involved in interior decoration does not exceed the construction area, top surface and wall area. If you only need to estimate it, you can use the following formula: wall area = ground area * 3, for example, you can use the building area to measure the area of latex paint.

Calculate the floor area minus the floor area of the bathroom and kitchen and multiply it by 3, the area of a house with a floor area of 100 square meters and the area of the wall is about 200-220.

2. The number of meters on the side of the door: the standard door is usually 2m * So the door is usually meters, the entrance door is usually 5 meters, and the bathroom and kitchen are usually meters, and the specific number depends on the specific size of the inner door. Window measuring instrument: The specific measurement size of the internal window shall prevail.

3. The estimated general area is the floor area * 85 = more than the internal area, then subtract the bathroom area of the kitchen, and then cut the balcony area by half, it is basically the floor area of the wall to be painted, using this number * 3 is basically the area of the wall. Usually, we usually use it to estimate the size of this engineering quantity, and the actual area is still determined by the measurement.

4. Calculation method of construction area: wall painting construction area = (construction area 80 -10) 3 construction area is the purchase area, the actual construction surface is 80, and the kitchen and bathroom are usually made of tiles and aluminum buckles. The area of the board is mostly 10 square meters.

The area obtained by the calculation method includes the roof, but its influence on the application of wall coatings is not very large and negligible (the actual measurement error is 10 to 15).

Here's what we've introducedCalculation method of wall painting area, aboutCalculation method of wall painting areaQuite simply, we can calculate and estimate how much material we can use before we buy them, so that we don't waste too little and delay the construction period.
