How to square the stairs by scraping the big white? What should I pay attention to when the stairs a

Many friends do not have a special understanding of the area calculation method of the staircase, and the staircase is white.

It also costs a sum of money, but how to calculate the area of the staircase scraped white? Are there some common formulas? The above two questions will be answered for you.

1. How to square the large white area of the staircase.

The area of the staircase is basically calculated by (length and width) 2 height, and the area of the top of the staircase is actually the long multiplication.

Wide. However, the specific area of scraping depends on whether there is an agreement in the contract, if there is an agreement, then we need to calculate according to the agreement, and if there is no agreed area, we need to calculate according to the area.

Second, what are the matters that need to be paid attention to when the stairs are scraped.

1. When scraping the staircase wall, it is also necessary to ensure that the wall is in a dry state, if the residual moisture on the surface is higher than 6%, it will also cause a certain quality impact on the construction surface.

2. In addition, before the construction of the staircase wall, it is also necessary to remove the debris and bulging places on the wall to ensure that the wall is in a flat state and then scrape the wall.

3. In order not to affect the construction process of scraping white, we will normally choose to construct when the temperature is higher than 7, the temperature is too low will lead to too high humidity, and the humidity will be too high in the case of the wall damp is more serious, and it will also have a certain impact on the service life of the wall.

3. Scrape putty on the wall.

After that, you can directly apply latex paint.

? After scraping putty on the wall, it is not possible to directly paint latex paint, because of putty powder.

There are many alkaline substances in it, and if you directly paint latex paint, it will lead to serious alkali reversal and wall peeling off of the wall in the future, which is also a matter that needs to be paid attention to during construction.

Stairs scrape the big white want to be a good amount, this square should be measured from the wide direction, and finally calculate it, the first point should be noted is that you must choose the kind of white, the quality of the big white is very good, so that the scraping effect is very perfect, the second point should also be noted when scraping, the wall should be very flat, scraped out of the big white is more beautiful.

The length and width is not calculated as the land area, what does x2 mean.

1. Method 1: stairwell wall area = stairwell net length * net height (or net width * net height) - deduct the area of door and window openings (this method is recommended) 2, method 2: stairwell wall area = stairwell perimeter judgment circle * (floor height - 2 * ladder height), subtract one step height when the top floor 3, stairwell wall plastering engineering quantity calculation, calculated according to the horizontal projection area, do not deduct the wall area occupied by the base land staircase 4, if you still don't understand, or the excavation collapse will not be calculated, do not want or have no time to calculate, It is recommended to find someone to calculate on behalf of you, there are agency companies, there are also agency individuals, and you can also go to the platform to entrust, and the cost varies.

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.

Summary. According to the provisions of the "Bill of Quantities of Construction Works", this kind of project should be calculated in the measure project, and the cost of the measure is generally borne by the construction unit or the construction unit. In the bill of quantities, measures refer to measures that do not belong to a single project quantity, but must be taken to ensure the quality and safety of the project, such as installing scaffolding, erecting protective nets, carrying out temporary electricity, carrying out temporary lighting, carrying out indoor protection, etc.

Therefore, the cost of measures for such projects as stairwell scraping needs to be calculated in the project cost.

How to calculate the cost of measures for stairwell scraping.

According to the provisions of the "Bill of Quantities of Construction Works", this kind of project should be calculated in the measure project, and the cost of the measure is generally borne by the construction unit or the construction unit. In the list of imitation quantities, the measures refer to the measures that do not belong to a single project quantity, but must be taken to ensure the quality and safety of the project, such as the installation of scaffolding and disturbance, the erection of protective nets, the use of temporary electricity, the temporary lighting, the protection of indoor buildings, etc. Therefore, the cost of measures for such projects as stairwell scraping needs to be calculated in the project cost.

Thank you. How to calculate the cost of measures for stairwell scraping.

Hello, stairwell scraping is an indoor wall repair project, which belongs to the measure project in the building decoration, so the cost of the measure needs to be calculated. The cost of measures refers to the cost of measures that do not belong to the scope of a single project quantity, but must be taken to ensure the quality of the project and the safety of the construction. The cost of measures to scrape the stairwell mainly includes the following aspects:

1.Installation of scaffolding: In order to ensure the safety and efficiency of construction, scaffolding needs to be installed in the stairwell, and this part of the cost needs to be calculated in the cost of the measure.

2.Indoor protection: During the construction process, it is necessary to protect the items around the stairwell to avoid damage to other items during the construction process, and this part of the cost also needs to be calculated in the cost of the measure.

3.Garbage removal: During the construction process, some garbage and waste will be generated, which needs to be cleaned up and disposed of, and this part of the cost also needs to be calculated in the cost of the measure.

4.Other measures: Depending on the circumstances, measures such as temporary electricity and temporary lighting may also be required, and these costs will also need to be included in the cost of the measures.

In short, the cost of measures to bury and scrape the stairwell is composed of many aspects, which need to be calculated according to the specific situation, and reasonable calculation and management are carried out in the project cost.
