What is the basis for calculating decorative engineering materials such as paints?

Algorithm: Total paint area Four-sided wall paint area Ceiling paint area. However, estimates are generally used.

Estimated painting area = room floor area * including walls and ceilings), and the amount of spraying is about one-third more. (Note: The actual amount of paint used will increase or decrease depending on the condition of the wall and the painting method).

At present, most of the decoration owners are constructed through professional construction personnel, so problems such as this can be avoided by carefully selecting high-quality decoration companies as long as they are grasped in general. In fact, when buying paint, what everyone is more concerned about or want is its decorative effect.

Generally speaking, there will be some differences in the engineering quantity calculation rules of decoration materials, depending on different decoration projects and regions, and the following is a brief list of several aspects that may be different:

1.Wallpaper: When measuring wallpaper, some areas will be calculated according to the area of the wall, while others will be calculated according to the number of wallpaper rolls, that is, taking into account different wallpaper specifications and losses.

2.Flooring: The same is the problem of quantity calculation, in some areas, the engineering quantity of the floor is calculated according to the number of the whole floor, while in some areas it is calculated according to the actual laying area.

In addition, the engineering quantity calculation rules for different types of flooring materials (such as laminate flooring, solid wood flooring, etc.) are also different.

3.Tiles: In the construction, some areas will use the "leftover material calculation method", that is, the tile corners that do not meet the standard specifications are measured and calculated according to a certain proportion to the number of tiles needed, while other areas do not use this calculation method.

4.Paint: The rules for calculating quantities of paint may also vary from region to region. For example, in the southern region of China, the amount of paint engineering is generally calculated according to the actual brushing area, while in the northern region, it may be calculated according to the wall area, also taking into account different loss rates.

In short, the engineering quantity calculation rules of decorative materials are very flexible and changeable, and need to be selected and adjusted according to the specific situation. For consumers, when choosing a decoration company or material company, it is necessary to pay attention to understanding the local engineering quantity calculation rules and related cost issues, so as to better control the decoration budget.

Generally speaking, the calculation rules of engineering quantities of decorative materials will be different from different industries, standards and regions, and the following are some decorative materials that may be different:

1.Wallpaper: Wallpaper is generally calculated based on the area or length of the wall, but different countries or regions may use different calculation standards, such as meters in Europe and feet in North America.

2.Flooring: Different types and materials of flooring will have different calculation methods, for example, the calculation of blind wood flooring is generally measured in square meters, while the calculation of carpet is generally measured in square feet.

3.Tiles: The calculation of ceramic tiles is generally based on the area or length of the wall, but the size of the tiles, the way they are placed, the gaps and other factors need to be taken into account when calculating.

In addition, the calculation of the engineering quantity of decoration materials will also be affected by factors such as construction methods, equipment, and labor, so it must be calculated according to the actual situation when decorating. It is recommended that you consult a professional renovation company or a design and grinding technician, who can give you more detailed advice.

Answer]: A This question examines the calculation rules and methods of paint and coating engineering.

1) Spray paint on the wall and cherry blossom paint on the ceiling. According to the size shown in the design drawing, calculated in area, unit: m2.

2) Empty lattice, fence quietly return to the rod brush paint. According to the size shown in the design drawing, the single-sided peripheral area is calculated, unit: m2.

3) Line brush paint. According to the size shown in the design drawing, the length is calculated, unit: m.

4) Brush fire retardant coating on metal components. It can be calculated by mass according to the size shown in the design drawing, and the bridge position can be transported in a single way; t；or calculated according to the design area, in m2. (5) Wood components are sprayed with fireproof coatings. The engineering quantity is calculated by area according to the design drawing, unit: m2.

Answer]: A2021 textbook p422

This question examines paints, coatings, and pasted land stove projects. Option B is wrong, the fireproof coating of metal components can be calculated by mass or by design area according to the size shown in the design drawing; Option C is wrong, the empty lattice, railing brush paint according to the size of the design diagram is calculated by the single-sided peripheral surface Wang rock volume; Option D is wrong, the line brushing is trapped and the imperial material is calculated by length according to the size shown in the design drawing.

Is the actual amount of paint applied to the same as the amount used by the above method? What is the relationship between the two?

Hello, Xiaohai, a home expert, is happy to rent you a solution or a trillion answer. The actual amount of paint is obtained on the basis of the actual coating rate, and the formula is as follows: actual amount of paint = area core product x dry film thickness 10 * volume solid content * 100 * (1-loss %) For example:

There is a storage tank inner wall of 2000m2, spraying 2 layers of phenolic epoxy paint with a volume solid content of 76%, each 150 microns, the estimated loss is 40%, and the total amount of phenolic epoxy paint to be used is calculated. Actual amount of paint = area x dry film thickness 10 * volume solid content * 100 * (1-loss %) = 2000 x 150 10 x 76 x 100 x = total 658 * 2 = 1320l If my answer is helpful to you, please give a thumbs up (in the lower left corner), I look forward to your like, your efforts are very important to me, and your support is also the motivation for my progress.
