Calculation method of putty powder dosage

During the decoration process, people often ask how much putty powder is needed for 1 square meter? Or how many squares can be scraped in 1 bag of putty powder? Today we will talk to you about the calculation method of the approximate amount of putty powder, and help owners and friends provide a reference for data calculation when choosing the amount of putty powder!

In fact, there are many factors that affect the amount of putty, such as the type of putty (different thickness), construction technology, etc., will affect the specific amount of putty powder, but the flatness of the base surface and the thickness of the scraping are particularly important. .

1. If the base surface is not smooth, it is recommended to use cement mortar first to roughly level the base surface for the first time, control the error of the base layer within 3-5mm, and then use putty products for fine leveling.

This has two advantages. First, it saves costs. If the error of the base surface is more than a few centimeters, a large amount of putty is required, and the cost is much higher than that of cement sand;

Second, the performance of the putty itself determines that it is not suitable for rough leveling. After a certain thickness is exceeded, the putty layer may crack and so on.

2. The thickness of batch scraping should also be well controlled . For different types of putty, there are also different requirements for the scraping thickness.

Therefore, we suggest that the complete putty scraping process should first check the flatness of the base surface. If the flatness exceeds 3-5mm, first use cement sand for rough leveling to control the flatness within 3-5mm; The putty on the bottom layer of the wall is used for fine leveling; finally, the putty on the inner wall surface is used for fine leveling.

Calculation method of batch brushing area points:

Batch brushing area = use area × 3 (generally 2-3 times of batch scraping)

1KG putty powder can batch out an area of ​​about 0.8 square meters

(According to the different types of putty, the flatness of the wall surface, the construction situation, and the thickness of the putty, there are some errors, and the data are for reference only!)

Note: If the scraping area of ​​a house is 100 square meters (not the indoor area), it is usually necessary to scrape putty 2-3 times. Get about 250 square meters (200-300 square meters, take the median value of about 250 square meters to calculate), 250 square meters/0.8 get 310KG, each bag is 20kg, and about 16 bags of putty powder are obtained.

Note: The actual amount will vary due to the different construction environment, substrate and construction process, and it is for reference only.
