Scrape the putty for the second time and let it dry for a few days.

As we all know, after scraping the putty, it is necessary to wait until the putty is completely dry before proceeding to the next step; If the putty is not completely dry, it is easy to crack when brushing latex paint; So how many days do we need to dry before the putty is completely dried for the second time? Next, Bian Xiao will briefly introduce it to you.

1, when we decorate the wall, we usually scrape putty twice and then paint the wall, paste wallpaper, etc. You need to wait until the putty is completely dried for the second time before proceeding to the next process. The drying time of putty for each time is about 2 days. The drying time of putty is related to the type, thickness and weather change of putty. If it is winter construction, it takes about 1 week for the putty to dry completely.

2. After scraping putty, if the weather is fine, you can open the window for ventilation to speed up the drying of putty. If it is raining or foggy, you can't open the window. Opening the window in this weather will easily lead to the problems of moldy, empty drum and cracking of putty. If you want to judge whether the putty is dry, the simple method is to touch the wall with your palm, and the dry wall can hear rustling; If the palm feels wet and stained with a lot of dust, then the putty is not completely dry.

According to experts from Qijia. Com, the number of putty scraping depends on the flatness of the wall. Generally, new houses are scraped twice, and second-hand houses are scraped three times. Putty batch scraping should not be too thick, with a thickness of about 2mm; The putty we choose should meet the national standards. The putty can be thicker for the first time and more delicate for the second time. Before we scrape putty, we need to stick cloth to strengthen the contact between the groove on the wall and the partition.
