Scraping putty is a technical job, and it is really troublesome to encounter an unprofessional master. Here, I strongly recommend that if you encounter a putty scraper who has any of the following behaviors, please do not hesitate to let him go.
First of all, what is absolutely intolerable is that the master directly scrapes putty without dealing with the base layer. If the plastering layer of the base layer is serious and the sand is serious, or the flatness of the wall is poor, direct scraping of putty will lead to cracking of the putty layer, uneven thickness, and seriously affect the appearance and durability.
Secondly, the thickness of the putty batch scraping cannot be ignored. If the batch scraping is too thick, the putty is easy to separate from the floor slab after solidification. Generally speaking, the putty should be scraped three times, and the thickness of each time should be strictly controlled, and the total thickness of the three times should not exceed 1.2mm, and the thickness of the first batch scraping should not exceed 0.5mm.
Also, make sure that the putty is dry each time before scraping the next one. If the first putty is not dry and the second time is rushed, it will lead to cracking and hollowing between the putty layer and the wall, which will seriously affect the quality of decoration.

In addition, be wary of the master adding glue to the putty. Although this makes the putty easier to apply, the glue contains formaldehyde, which can lead to increased indoor pollution and pose a threat to the health of your family. Moreover, after the putty is sealed, it is not breathable, which can easily lead to mold of latex paint and wallpaper.
Therefore, when decorating, it is necessary to require the master to use a good water-resistant putty, which can be used directly with water without glue, which is not only firm and durable, but also moisture-proof. At the same time, the freshly blown putty should be avoided from blowing directly by cold wind to prevent it from drying out.
In short, decoration is no trivial matter, and every detail is related to the quality of the home and the health of the family. For technical work such as scraping putty, we must strictly control to ensure the quality of decoration.
