How to calculate the price of wall paint, how to calculate the engineering quantity of wall paint

What should you do if you want to calculate the amount of paint used for an entire wall and budget how much paint you need to buy for the whole room? Many owners don't know how to calculate the construction area and amount of wall paint when buying decoration materials. How do you calculate the amount of wall paint you use?

The following is the calculation method of the wall construction area and paint consumption collected by the Beijing decoration company. 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 in 10 square meters, the area obtained by the calculation method includes the ceiling, the ceiling is not very important to 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.

With the above calculation method, I believe you will not be confused when buying decoration materials. It's easy to get on a budget with pay-as-you-go.

If you buy from the manufacturer, it is normal to calculate the price according to kilograms and liters, and Mingbang Chemical is generally calculated by kilograms.

Calculated according to the opening area of the exhibition wall, calculated in square meters, the engineering quantity = wall length x plastering height of the inner wall, deducting the area occupied by the door and window openings and empty rings.

The area of the baseboard, the hanging mirror line, the inner hole and the junction between the wall and the component is not deducted, and the side wall and top surface of the hole are not increased. The area of the side wall of the wall buttress and the chimney of the attached wall is calculated together with the amount of plastering of the interior wall, and the length of the plastering of the interior wall is calculated by the net length of the diagram between the main walls.

Interior wall plastering height: if there is no wall skirt, it is calculated according to the distance between the indoor ground or floor and the bottom surface of the ceiling; If there is a wall skirt, the distance between the top of the wall skirt and the bottom surface of the ceiling is calculated, and the height of the interior wall plastering of the slatted ceiling is calculated according to the indoor ground or floor to the bottom surface of the ceiling by adding 100mm.

Calculated by area, after deducting the area occupied by doors and windows, it is the area of the wall, and you can analyze how much paint and labor are used by applying the quota of your area.

Quantity of paint: Some paints are calculated by area, and some paints are * coefficient (such as plastering surface paint is calculated according to the plastering area, wooden doors and windows, iron doors are calculated according to the area of doors and windows * coefficient).

Calculated by area.

There is not much on the side walls of doors and windows, and it depends on your discussion with the decoration.

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.

The packaging of paint emulsion paint is basically divided into two specifications: 5 liters and 15 liters. Taking the 5-liter capacity commonly used in the home as an example, the theoretical coating area of 5 liters is 35 square meters for two passes. If you need decoration paint, latex paint, it is recommended to choose Taysher.

Paint emulsion paint is calculated by subtracting the area that does not need to be painted, such as kitchens and bathrooms. The painted area of the ceiling of the house = the usable area of the floor of the house. Calculation of the amount of latex paint:

The painted area of the wall of the house = the usable area of the floor of the house 2. The total painted area of the house = the painted area of the ceiling of the house + the painted area of the wall of the house. According to the amount of latex paint used, calculate the amount of latex paint.

Dosage (number of cans) = total painted area of the house Number of reps (usually 2 reps) Paint consumption per square meter Packing volume. The specific amount needs to be slightly increased or decreased according to the specific situation of the house. [Understand the market prospect of art paints].

The area of a house of 90 square meters, the general wall area is calculated according to or 3 times, which is about 250. If you follow the primer and topcoat on your **. The primer needs to be filled with 5 barrels of 5L.

If you need 2 barrels of more than 20kg of topcoat for 2 times, it is recommended that you buy 2 barrels of 20kg, and then buy 2 barrels of 5L topcoat.

The wall area of your house should be about 320 square to 380 square meters, and one kilogram of topcoat can brush 3-4 square areas (twice), according to this calculation, you need to use about 4 buckets of 20 kg of topcoat, and the amount of primer, one kilogram of primer can brush 10-15 square areas, and your house will use 20 kg of primer 2 barrels!

For a house of 90 square meters, you have to calculate the wall area! To give you a rough calculation, about the area of the wall is about twice (estimated in the southern region), about 350 square meters of refresh area; In general: the primer is better, and the topcoat is used less; Count it out like this:

The primer is basically OK with 4-5 barrels of 5L, and the topcoat is OK with 3 barrels of 5L.

The area of general paint is multiplied by a coefficient of the construction area to obtain the area of painting, this coefficient is generally, it is recommended that the owner of the building use, a total of 225 square meters, the area of the primer is 225 square meters, and the two topcoats are 450 square meters.

Are you decorating yourself? Or find a worker to help you decorate, if you decorate yourself, use a good wall paint, I recommend you buy 3A latex paint, this is the best latex paint, ** in about 150 a bottle, a bottle is about kgIt doesn't take much, and it's more than enough to buy a barrel of a size like yours.

The walls have to be painted. Including the two walls of the window and the door frame, as long as the place where the white cement has been brushed, you must brush it again, note: the tiles do not need to be brushed.

Let me tell you that! If you are 15L, you can theoretically brush 180 square meters! It's actually only 150 square meters! Or so do you! 1 liter can be brushed 12 square meters!

Your primer is 5L, it is estimated that you will have 3 barrels, the worker is estimated to buy you 4 barrels, and the topcoat is 20 kilograms, 1 barrel is enough

If you don't want to waste it, you can calculate it according to the actual area of the wall, and if you don't want to think about it so much, you just ask your fan master and ask him to estimate it.

Calculated by Yuema white closed primer + antibacterial aldehyde removal healthy water paint:

Brushing area = (building area 80%-10) 3 200m ;

The amount of primer required (one pass) = bucket (barrel);

The amount of topcoat required (two passes) = barrel (18kg barrel);

This calculation result is for reference only, the actual consumption depends on the construction environment, it is recommended to buy more paint when buying, to avoid the color difference problem caused by the need to buy new paint is insufficient.

Painting the walls is an indispensable step in the home decoration process. When it comes to decoration, the point that everyone is most concerned about should be the ** part. So how much is the wall painting**?

Generally speaking, the labor cost of painting one square meter of wall is about ten to twenty yuan, and the remaining ** depends on many factors, such as the materials used in painting, and subsequent retouching. Therefore, it is actually quite difficult to calculate the wall painting. Here is an introduction to a method that is suitable for most people to calculate wall painting.

The original condition of the wall is a factor that can not be ignored in calculating the status of the wall painting, if the wall has been renovated and has been decorated, we should take into account the treatment of the wall when making a budget, in addition, if the wall is very dilapidated or uneven, the preparation work before the wall painting, such as finding the equal, needs to cost more.

In fact, everyone generally does not ignore the factor of wall area, so there is no need to say more. The larger the area, the higher the wall painting**, but sometimes the project is very large, the decoration company may give some discounts, you can try to fight for it.

Wall painting material can be said to be the most important factor affecting the wall painting, in the case of the same wall area, the final ** of different stucco materials may be very different.

Everyone's requirements for decoration effects are different, some people live more exquisitely, and the requirements for the wall may be relatively high, which may increase the time for wall painting, and also increase the wall grip surface painting.

Calculating the wall painting ** is a step that cannot be omitted when making a decoration budget, because the cost of demolishing the sparrow for this aspect is still quite high, if you ignore it, it is likely that Duan Yuwei will exceed the budget in the end, leading to a dilemma. This also tells everyone to be careful at every step when decorating.

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

If the area of your house is 143 square meters, then the painted area = (143-23) * 3 = 360 square meters.

According to the calculation of 4 5 square meters of latex paint brush per kilogram twice, you can calculate how many barrels of paint to buy. The primer can be brushed once, so the amount will be less than half that of the topcoat.
