How do you calculate the area of scraping putty powder? On what basis?

Now many qualified people will choose to buy a house, unless they buy fine decoration, otherwise most of them need to be decorated, then the decoration is of course inseparable from the putty.

Try to calculate it according to the actual area

In many places, the charge for scraping putty is calculated according to the construction area, but the construction area is sometimes not as accurate as we think, so it is more reasonable to calculate it according to the actual area of putty.

Negotiate with the workers about the cost of scraping doors and windows

Some people's doors and windows are not scraped putty, so the cost is not counted in it, but the workers will feel that it is more troublesome to close the doors and windows, so they will calculate the entire area of the doors and windows, and all this should be discussed before construction.

3. Try to measure the place where the putty is scraped before construction

There are many construction teams in the process of construction will falsely report the area of some putty, which is also unfavorable to the owner, so we have to measure the area of scraping putty before construction.

In addition, the charge for scraping putty is also a headache.

Many people are also afraid of being pitted, so let's talk about the precautions about charging.

(1) It is calculated according to the local price

There are many places where the charges are more reasonable, if it is said that it can be calculated according to the construction area of about 20 yuan a square meter, then this ** is still more affordable, so it is convenient to calculate, but this needs to be decided according to the price charges in various places, not unified, for reference only.

(2) Pay attention to the number of times you scrape putty

The number of times to scrape putty should be made clear to the workers before construction, some people collect ** once, some people say three times, this ** is to say good, can not be cheap.

(3) Understand the included fees

In some places, the reported putty scraping ** is not counted as grinding, so it is necessary to understand the cost of scraping putty before letting workers construct, so as to avoid losses.

(4) Refer to other owners who have been renovated

Generally speaking, there are many new communities with model homes.

You can refer to their owner's scraping putty**, and then consider whether to count the doors and windows, which is also more affordable.

It should be calculated according to the construction area or the area in the suite, or the most accurate actual measurement method can be used to calculate; In fact, when scraping putty powder, it is necessary to calculate according to the accurate measurement of the room, which is the most cost-effective and can calculate the actual amount of construction.

The area of scraping putty powder can be calculated using the standard formula, the construction area multiplied by 3 = the total area of putty powder, but there are still openings such as doors and windows indoors, and then the area of the doors and windows is calculated, and the area of the hole is subtracted from the total area *, which is a more accurate area of scraping putty powder.

The standard formula will be used to calculate, the area of the building multiplied by 3 is the area of putty powder, under normal circumstances, the master is calculated in this way.

Scrape putty. The area of the powder can be calculated using the standard formula, the construction area multiplied by 3 = the total area of putty powder, but there are still openings such as doors and windows in the interior, and then the area of the doors and windows is calculated, and the area of the hole is subtracted from the total area *, which is the area of the putty powder that is more accurate.

What are the standards for wall scraping putty powder?

The standards for wall scraping putty include wall flatness and yin and yang angles.

Verticality, construction materials and proportions, etc., among which polyvinyl chloride is selected as the material for scraping putty.

Particle blending agent, double fly powder, water-based putty powder, etc., water-based putty powder requires fineness to pass through the sieve hole of more than 380, whiteness greater than 97%, glue, double fly powder, putty powder ratio of 1::.

What is the construction process of scraping putty?

First of all, the base layer needs to be cleaned: the base layer needs to be treated before scraping putty, including plastering the wall.

The position of the top plate, column, plate joint, etc.

It should be cleaned up to avoid dust, slime, splashing, oil, etc., which affect the scraping effect of putty. Then the base scraping: the putty powder can not be scraped immediately after mixing evenly, you need to use the putty batch knife to scrape the putty to the base layer thinly, scrape it flat, do not need to scrape, keep the joints flat, and dry for a day after scraping.

The last scraping: the next day after the putty scraping, you can carry out large-scale scraping construction, first scrape a thin layer on the surface, and when the surface is slightly solidified and still wet, you can continue to use the putty batch to select repeated sticky water scraping, and the putty layer that is required to be scraped is free of scratches, joints, bubbling, potholes, penetration, porosity, etc., and the surface should be kept smooth and clean.

Putty powder should be appropriately proportioned when decorating, if it is too much or too thin, it will lead to a bad effect, when choosing putty powder, you should choose environmentally friendly products, choose a regular big brand, putty powder is not high, but the amount of decoration of the whole house is very large, but for the sake of family safety, you must choose a big brand, remember to ventilate after decoration, because putty powder will have some smell.

Based on the actual area, workers will directly measure the area of the wall, generally multiplying the length by the width to calculate an approximate figure. Then add up the area of all the walls to get the area of the wall that needs to be scraped. For example, the area of scraping putty in the kitchen is 10 square meters, while the bathroom is 12 square meters, the bedroom is 20 square meters, and the living room is 25 square meters, so the total area is about 67 square meters.

In the case of general home decoration, the length of the house is multiplied by the width and height of the house, which is the area of scraping putty in the set.

It can be calculated using a standard formula. Floor area multiplied by 3 = total area of putty powder.

How is the area of scraping putty powder calculated, and what is the area factor? Today is a long time to see.

Answer: According to the construction area of the house given by the developer multiplied by the fixed coefficient value, taking a house with a construction area of 90 square meters as an example, if you apply the formula to calculate, you can get that the area of this house is 225 square meters. However, the coefficient of multiplication of the formula is too large, so the accuracy of the formula for calculating the area of this kind of scraping putty is not high, and there are some differences.

It is easy to cause the calculated area to be larger than the actual scraping putty area, increasing the expenditure of decoration costs, but some painters will use the fixed coefficient to calculate, so that the scraping putty area is similar to the actual painting.

When scraping putty powder, how to calculate the area?

The charging method of blowing stuffy children is usually calculated according to the construction area, which is relatively simple and convenient, and there is no deception in blowing boring! There are also owners who require that when calculated according to the actual area, it is the most standard charging method for doors and windows to be divided into half empty, and it is still decided according to the actual unit price of the blowing fuer.

Some people will think that the charge for scraping putty is unreasonable, like which doors and windows should be completely reduced, and it seems reasonable to not charge where you don't need to blow, but you have to know that it is more troublesome when you don't know how to deal with a door and window, we would rather reduce the good scraping of doors and windows The actual situation is that there are more than half of the air, or the area discussed by both parties, and the doors and windows are halved manually or not reduced, in fact, the final result is basically the same, and the gap is not big.

The putty we built a house made was 6 yuan per square (triple putty), which was very cheap! However, if you want to remove all the doors and windows, you have to remove them first. First of all, the empty package calculation, that is, the virtual square billing does not exclude the door or the window, polishes 3 blocks of one square, and brushes 5 blocks of one square, all of which are calculated by the empty area.

I guess it's the flattest ** in the world?

If the calculation of the construction area is simple and convenient, how much trouble is saved, and the owner is worried about the pit, the worker is worried about the small amount in vain, and the owner is unwilling to do so. Calculated according to the construction area can save these troubles, our charging standard is 18 25 yuan a square meter, converted into the actual square calculation is about 6 pieces of a square, so according to the construction area is a reasonable 1kg putty powder can be batch square area (according to different types of putty thickness, wall flatness, construction, putty scraping thickness, etc., there is an error cavity dry, data for reference only) Note: If a house scrapes an area of 100 square meters (not an indoor surface round convolution), Generally, you need to scrape the putty 2-3 times.

Get about 250 square meters (200-300 square meters, take the median value of about 250 square meters), 250 square meters is 310kg, each bag is 20kg, and get about 16 bags of putty powder.

What should I do if the color difference occurs <> putty powder? Putty powder is often used in ingots paint, its adhesion to ingots is very firm, and it is not expensive, so it has entered the market for many years and has a high utilization rate, but in the process of scraping putty construction, we will encounter such a situation - scraping putty appears color difference, putty appears color difference, what is going on?

Scraping putty powder can be said to be a necessary project when we carry out interior decoration, mainly to do the bottom bottom treatment of the wall, and then the surface can be pasted with wallpaper or whitewashed latex paint, so it also plays a major role, but I believe that many owners are in the process, the general decoration company or construction workers, calculate the area of the wall scraping putty, the formal algorithm is according to the perimeter of each space The height of the house (if the door opening and the window are not covered) The area of the window and the door opening is halved, such as the area of the door opening is 2 square meters, If the owner calculates according to the usable area, then as a scraping master, he is still multiplied by the construction area by 3 times how much money per square meter, how much is the specific amount of money, depending on what you do, the scraping master is counting how many jobs are needed for this job, <>

For example, if the floor area of a house is 100 square meters, according to this formula, the construction area of the workers is 250 square meters. This algorithm is obviously beneficial to workers, mainly because the coefficient is too large, so that the calculated construction area is significantly larger than the actual decoration The most important thing is to scrape putty, paint, because carpenters do ugly work, scraping putty can be covered, now it is not easy for young people to make money, the house decoration is deep, many of them are buying materials to find workers to do, but they don't know the price of work in the trouser field. Our side is generally calculated according to the ground area multiplied by four, the kitchen and bathroom are removed, that is, the position of the non-scraping is removed, scraped three times, once the exterior wall putty is twice the interior wall putty, after polishing, the type is simple with latex paint, the price is not high six yuan and one flat, if there is a gypsum ceiling or.

For decoration whites, there is a problem that will inevitably be encountered, that is, how to scientifically estimate the amount of putty, buy more, return and exchange trouble, buy less, and fear of delaying the construction period. I don't know how to calculate the hail product of the surface in other regions, so let's talk about our place. The algorithm here is the empty side calculation, that is, the circumference of the room is added up and multiplied by the room height, and the door opening and window are also counted, which is the empty square calculation, <>

If you calculate, then you can use the Wang Mo formula of chemistry to calculate, the effect is very good, and the final calculation result is also very clear, which can contain enough to achieve a very good ideal effect of Tan Lingchun.

The calculation method is very simple, just add up the area of each wall and remove the area of the doors and windows.

In fact, if the square area of scraping putty powder is calculated, we can calculate it according to a formula for missing with a trillion yuan, that is, the construction area x3 is the total area of scraping putty powder, but we still have doors, windows and other openings in the room, and then we need to calculate the rolling area of doors, windows and other openings, and then use (total area - hole area), this is a more accurate area of interior wall scraping putty powder, if we don't know, you can directly use this formula to calculate the rent.

1. The floor area of the house is calculated as the surplus of ants.

You can multiply the coefficient value according to the building area given by the developer, and the area of scraping putty = construction area. For example, for a house with a floor area of 90, the area of scraping putty is 225. However, the accuracy of the calculation formula of this kind of scraping putty area is low, which is easy to cause the calculation area to be too large, and at the same time increases the expenditure of decoration costs.

2. Calculated according to the actual area of the suite.

If it is not calculated according to the construction area, you can also use the area in the set to multiply the coefficient value, and the formula is the area of scraping putty = the area in the set. For example, the floor area of the stuffy land is 90, the common area is 20, and the actual area of the suite is 70. Applying the formula to calculate, the scraping putty area is 245, which is relatively closer to the actual scraping putty area.

3. Calculated according to the area of the interior wall.

Multiply the building area of the house by the fixed coefficient value, if the area of the doors and windows of the house is not deducted, the multiplication coefficient is 3, and the area of scraping putty = the area of the interior wall is 3. If you deduct the area of all doors and windows, the area of putty scraping = the area of the interior wall.

4. The area at the top of the wall is calculated.

The formula is relatively simple, calculating the size of the top surface of the wall of the house space, that is, the length, width and height, according to the actual measured area of the damage difference. At the same time, it is necessary to subtract the area of doors and windows, which is more accurate in calculation, but it is more suitable for using a regular standard house space.

How many times do you need to scrape putty on the wall?

Under normal circumstances, the wall needs to be scraped three times, the thickness of the first putty is between 4 mm and 5 mm, and the thickness of the second and third putty is between 2 mm and 3 mm.

Some people may have a certain misunderstanding of the thickness of putty, thinking that the thicker the scrape, the higher the flatness of the wall, in fact, the putty scraping too thick has a certain impact on the later wall coating, which may make the wall paint fall off or bulge.

What preparations do you need to make for the wall before scraping putty?

First of all, it is necessary to see if there is any crack in the wall, and if there is, then the cracked part of the wall needs to be repaired with kraft paper; Then use cleaning tools to clean the dust on the wall; Finally, apply the interface agent to the wall again, and only scrape the putty after the interface agent is dry.

What is the cause of cracking, blistering and depowdering of the putty layer?

The main reason may be that the base layer is not completely dry before scraping the putty, or the construction speed is relatively fast when scraping the putty, or even the thickness of the putty layer has exceeded 2 mm after scraping.
