When scraping putty, it is generally necessary to scrape 2 times, and each time a time interval is required, and at this time, it is necessary to pay attention to the time of the interval, so the putty can be scraped twice in a few daysWhat should I pay attention to when scraping putty?
The putty can be scraped a second time in a few days, depending on how dry the putty is the first time.
Generally speaking, putty needs to be scraped a second time after an interval of about two or three days. If it is a wet day or a rainy day, the interval can be appropriately extendedIf it is winter, due to the low weather temperature, the putty will dry for a relatively long time, and it generally takes about a week;In summer, the weather temperature is high, and it is generally enough for two to three days.
If the first putty is not dry, scraping the second putty is easy to cause dryness and shrinkage, and the interval between two putties is too short, which is also easy to cause peeling and peeling. Therefore, when scraping the putty for the second time, you need to check the dryness of the putty for the first time to ensure that it is dry before scraping the second putty.
What should I pay attention to when scraping putty?
1. Tool selection: appropriate scrapers should be used, and the size and model of the scrapers should be selected according to the construction area and needs.
2. Surface treatment: Before construction, the surface to be scraped should be cleaned and treated. If necessary, it should be sanded to ensure that the construction result is smoother.
3. Putty dosage: Putty should be evenly applied during the construction process, and should not be over-scraped, otherwise it is easy to cause problems such as uneven surface and cracking.
4. Construction skills: carry out the scraping operation in a certain order, do not repeat the scraping, and prevent the phenomenon of scraping. In the construction process, it is necessary to do a good job of environmental protection and avoid dirtying the surrounding environment.
5. Construction environment: pay attention to temperature and humidity during construction, and choose appropriate construction conditions according to different putty materials.
6. Construction time: The putty needs to be fully dried after application, and during this period, avoid other construction operations to avoid damage to the surface.
7. Wall base treatment: pay attention to the flatness of the wall base before scraping putty, if the wall potholes are large, you should first use gypsum putty to level it, and then scrape the putty.
