Calculation of exterior wall paint area How to calculate the area of exterior wall paint

Measure the doors and windows first, their area should be fixed (referring to a door and a window), it can't be the same, and the length and height of the exterior wall area should be measured. The total area is out, minus the total area of the door and the total area of the window, and the list of the outer list of the door and window frame should be deducted, and the valuation is calculated according to the actual size.

The fixed rate is calculated in square meters according to the vertical projection area of the exterior wall, the decorative line and greater than 0The paint is calculated in square meters in the dimensions shown in the diagram. The area occupied by the 3 square meter hole.

The special graphics are calculated in square meters according to the illustrated size of the actual design part, and the area of the side wall of the hole is not increased. The plastering area on the side of the attached wall buttresses, beams and columns is incorporated into the calculation of the plastering quantity of the exterior wall.

Calculation method: 1. Measure the doors and windows first, and this area should be fixed (referring to one door and one window).

2. Measure the length and height of the exterior wall. The total area is out.

3. Subtract the total area of the door and the total area of the window, this is the area of the exterior wall coating.

Attached: wall buttresses, beams, column side plastering area into the external wall plastering engineering quantity calculation, paint to the size of the diagram in square meters, special graphics according to the actual design part of the size of the diagram in square meters, others in the area calculation.

The list pricing is calculated according to the actual size The fixed pricing is calculated in square meters according to the vertical projection area of the exterior wall, and the area occupied by the periphery of the door and window frame, the decorative line and the hole larger than the square meter should be deducted, and the area of the side wall of the hole is not increased. The plastering area on the side of the attached wall buttresses, beams and columns is incorporated into the calculation of the plastering quantity of the exterior wall. The paint is calculated in square meters in the dimensions shown in the diagram.

Special graphics are calculated in square meters according to the illustrated dimensions of the actual design parts. Others are calculated in terms of area.

Both interior and exterior walls are the same truth: (wall area + top area - door and window area) and then it depends on how much amount of paint each square to divide the above area to get the amount of paint required.

Calculated by area according to the dimensions shown in the figure.

Summary. Hello dear, glad to answer for you. The area of exterior wall paint is calculated as follows:

Exterior wall paint is mainly calculated in square meters according to the vertical projection area of the exterior wall, and the decorative lines, door and window frames, the area occupied by the holes larger than square meters and some invisible areas are deducted. The total painted area is converted from the ground area to the total painted area: the total painted area of the paint = the paint area of the four walls + the paint area of the ceiling The paint area of the four walls = the ground area The ceiling paint area = The ground area Therefore, the total painted area of the paint (including the ceiling) = the ground area Note:

It will increase or decrease depending on the ceiling height and the number of doors and windows).

Hello dear, glad to answer for you. The calculation method of brushing the area of exterior wall paint is as follows: the exterior wall Zheng Ying paint is mainly calculated in square meters according to the vertical projection area of the exterior wall, and the decorative lines, the periphery of the door and window frames, the area occupied by the hole larger than the square meter and some invisible areas are deducted.

The total painted area is converted from the ground area to the algorithm: the total painted area of the paint = the area of the four walls coated with the sedan + the ceiling paint area of the four walls painted = the ground area The ceiling paint area = the ground area Therefore, the total painted area of the paint (including the ceiling) = the ground area Note: It will increase or decrease due to the height of the ceiling and the number of doors and windows).

Extended information: Some exterior wall paint areas are measured and measured, and the actual area is basically different from the drawings. If there is no modeling, it is a good amount, the elevation is multiplied by the width, the window area is reduced, and the area of the window canopy is added, and the balcony area is calculated if there is a modeling.

Brush wall area = length x width or length x height (the area of doors and windows cannot be counted, and all should be removed). In addition, this measurement method is the most accurate and transparent, but it is only suitable for standard units, and lofts and duplexes are measured according to the actual situation. The process of painting the wall is very simple, first apply 2-3 times with environmentally friendly putty, polish and smooth, then apply 2-3 times of wall paint, then brush 1 time of primer, 2 times of topcoat, and then it is done!

No matter which of the above is chosen, it is recommended that the owner should confirm the area with the construction team in advance and negotiate the price when painting the wall paint, so as to avoid disputes afterwards. Note: Amount of lacquer:

According to the requirements of the construction procedure of the standard section beam, the thickness of the primer is generally 30 microns, and the construction area of the 5-liter 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. As mentioned above: the amount of primer = construction area 70 topcoat amount = construction area: 35

Hello dear, glad to answer for you. How to calculate the exterior wall paint according to the construction area of home decoration, there is some waste. Let's take the area of wall paint painting as an example and take a look at the following calculation method, so that you can save money.

The formula for calculating the area of wall paint painting: 1. The area of wall paint painting = (construction area 80% -10) 3 construction area is the purchase area, the actual utilization rate is generally about 80%, the kitchen and bathroom are generally the use of ceramic tiles, aluminum buckle plate of the pickpocket, the area of this part is mostly in 10 square meters, the area obtained by the calculation method includes the ceiling, the ceiling has a very small impact on the rough area of the wall coating, It can be disregarded (the result of this formula is likely to be the closest to the actual area). 2. The amount of wall paint is in accordance with the requirements of the standard construction procedures, 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 wall paint is 60 70 microns, and the construction area of 5 liters of wall paint is generally 30 to 35 square meters.

3. Primer amount = construction area 70 topcoat amount = construction area 35 building area of 120 square meters of house, the amount of paint required: wall spring bench surface paint area = (120 80%-10) 3 = 258 square meters of primer amount = construction area 80 (coating rate 1 time) = 258 80 = barrel) that is, 4 barrels of topcoat amount = construction area 45 (coating rate 2 times) = 258 45 = barrel) that is, 6 barrels 4, wall paint amount calculation: first of all, calculate the painting area, Once you have the paint area, you can divide the paint area by the area per litre of paint to get the amount of paint you need.

For general interior wall finishing, there is an empirical formula to calculate the painted area: liters of wall paint required to apply a layer = (building area per liter of painted area). For example:

For a new house with two bedrooms and one living room of 80 square meters, the painting area is about 200 square meters of wall, and each liter of Desert Oasis anti-fouling wall paint can be painted with 13-16 square meters, and a bucket of five-liter Desert Oasis anti-fouling wall paint can be painted with about 40 square meters of two layers of wall, then a total of 5 barrels of 5 liters of Desert Oasis anti-fouling latex paint are required to paint this room, including ceiling. In addition, the wall paint painter is generally charged according to the square meter, but the owner often ignores how to charge the door and window area before brushing, and some people will feel that the door and window area is deducted on the line, but it is understood that whether it is a decoration company or a painter, the door and window area will not be removed when the wall paint is painted in the living room pastoral furniture, but there is another charge because of the high technical difficulty of brushing the door and window side wall, but the charging standard is not uniform, and it is recommended that the owner should negotiate the price when painting the wall paint, so as not to cause disputes afterwards. Construction technology Base wall requirements:

The surface of the base layer should be firm and tidy, and there should be no cracks, no peeling, no dust, and no oil stains; The moisture content of the wall should be less than 10

Calculation of exterior wall plastering quantities:

1. The amount of exterior wall plastering is calculated in square meters according to the vertical projection area of the exterior wall.

2. The area occupied by the door and window openings, exterior wall skirts and larger than the holes should be deducted, and the area of the side wall of the hole should not be increased.

3. The plastering area on the side of the attached wall buttresses, beams and columns is incorporated into the exterior wall plastering project.

Wall paint construction area (Floor area 80 10) 3

The construction area is the purchase area, the actual utilization rate is generally about 80, the kitchen, the bathroom is generally made of ceramic tiles, aluminum gusset plates, 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 dosage Construction area 70;The amount of topcoat used in the construction area is 35.

General interior wall calculation, it includes four middle area and top area. Because of this bedroom he has open windows and doors. So in the total area is the area of windows and doors that need to be subtracted.

So the area of the interior wall is the area of the 4 perimeter walls plus the area of the top wall minus the area. So the walls of the interior are calculated like this.

1. Estimation and calculation method: construction area is equal to construction area Example: construction area is 90 square meters, and the actual construction area is equal to square meters.

2. Calculation method of construction area: wall paint construction area = (construction area 80%-10) 3 construction area is the purchase area, the actual utilization rate is generally about 80%, kitchen, bathroom is generally made of ceramic tiles, aluminum buckle plate, this part of the area is mostly in 10 square meters, the area obtained by the calculation method includes ceiling, the ceiling has a very small impact on the construction area of wall paint, can not be considered (the actual measurement has 10---15 square error).

4. The most accurate actual measurement method: length x width, length x height, door and window area are all removed, the above measurement methods are only suitable for standard house types, standard lifting height (attic and retest according to the actual measurement) At present, the calculation method we use is the 4th, which is also the most accurate and transparent.

Summary: The estimation method, the construction area calculation method, the area calculation method and the actual measurement method can all be used as the wall area calculation method, but the actual shared area of the house, the size of the doors and windows, the height, etc., will affect the wall area, so the most accurate and ideal is the actual measurement. Therefore, most of the calculation methods currently used are the fourth, and the actual measurement method is also the most accurate and transparent.

The wall area includes the surrounding area and the top area, because this bedroom has windows and doors, so the windows and the area need to be subtracted. According to the title, it can be obtained:

The area of the four walls:

Area of the top wall:

Window area: Door area:

So the area of the wall = the area of the surrounding wall + the area of the top wall - the area of the window - the area of the door =

So the area of the wall is:

If the drawing has dimensions, it is best to calculate according to the drawing; If calculated based on empirical values, the answer is the floor area of the interior * the area of the interior wall; Of course, in order to get an accurate answer, it is recommended that you find a special home inspection company to come to the site to measure, thank you!

The area of latex paint wall painting is calculated according to the area. Latex enamel worker, I am about 10 yuan manual in Nanning. The wooden paint hand brush is 25 yuan square, and the spray paint is 45 yuan square for your reference, because the labor price is different in different cities. Hope to adopt.

Wall area = indoor perimeter * indoor floor height - (half of the area of doors and windows) door = m Pass = m Generally, this is how it is calculated.

Construction area * 3 * labor unit price, complex modeling addition. Plus wood lacquer artificial.

Chengdu is about 12 square meters.

By area.

The sum of the length of the exterior walls multiplied by the height of the room, this is the first part!

The sum of the length of the interior walls (visible on both sides of the wall) multiplied by the height of the room, this is the second part!

The area of the two parts adds up to the area of the interior wall, which generally has to be painted!

How to calculate the area of wall latex paint.

Look at what latex paint is generally between 15-35!

Formula for calculating the amount of paint:

1. The usable area to be painted = the usable area of the room.

2. The theoretical coating area of a single layer of paint per barrel = the theoretical coating area per liter x the net volume content of each barrel of paint.

3. The amount of paint consumed once painted (i.e., the number of barrels) = the practical area to be painted The theoretical painting area of a single layer of paint per barrel.

4. The total paint consumption of two times (i.e., the number of barrels) = the amount of paint consumed by one brush x 2 times.

In fact, it will be written in the barrel body, because the brand is different, the amount of water added is not the same, but also according to the actual construction situation, such as too hot and too cold, etc., the proportion of water added is different, and the amount of paint consumed is different.

Hello dear, the key to calculating the paint area of the exterior wall is to accurately measure the height and length of each wall. Here are the steps to calculate the exterior paint area:1

Measure wall height: Measure the height of each wall with a ruler and measuring tools, from the floor to the top of the wall. Suppose the wall height is h1, h2,..

Measure the length of the wall: Measure the length of each wall with a ruler and measuring tool, from one end to the other. Suppose the wall length is l1, l2,..

Calculate the wall area: multiply the height and length of each wall of the imaginary finger bridge to get the area of each wall, which is expressed as a1, a2 ,..an。

The formula is ai = hi to calculate the total area of the exterior wall: add the area of all walls to get the paint area of the entire exterior wall, which is expressed as a and the formula is a = a1 + a2 + an. It is important to note that if there are windows or doors in the wall, you need to subtract their area.

If the wall is irregular, you can divide it into regular rectangular areas and add them up to get the total area. In addition, it is also necessary to take into account the coating rate of the paint when calculating the paint area, and the paint coating rate of different brands and models is different, so the amount of paint required should be calculated according to the actual demand when purchasing the paint.
