In summer, the window is not opened after the putty has been scraped on the wall, and it is inevitable that the wall will grow hair.

Answering a question from an owner today, the owner said that it has been half a month since the putty was shaved at home, and the windows have not been opened for a week. Now there are hairs growing on the walls. What is the cause? What should be done to remedy it?

It is normal for this problem to appear in the current season. Now the temperature is very high and the humidity is very high.

After shaving the putty, the putty contains a lot of water vapor. If the doors and windows of the house are closed tightly, the house is like a sauna, which will lead to long hairs in some parts of the wall.

Now this season, after shaving the putty, don’t close all the windows, at least open one inside to maintain a natural air circulation, so that the water vapor generated in the house can be drained in time. In this way, although the putty will dry slowly, it can ensure that the putty will not grow hair.

The wall has grown hair for this reason, what should I do?

If this happens, don’t worry, take measures to let the house dry as soon as possible, such as opening the window or blowing it through a high-power fan. After the wall is dry, you can polish these long hairs. , and then continue to scrape the putty down.

This treatment method should only be used for small areas. If the area is relatively large, it is recommended to shovel all the putty, and then re-scrape.

Some owners may say that there are many people on the Internet who say that the doors and windows should be closed after scraping the putty to prevent the putty from cracking.

This statement is not rigorous. Scraping putty is different from brushing latex paint. The water content in the putty is quite large. After scraping, it will inevitably cause problems if it is not drained in time.

And opening the windows is the best solution. It is not advisable to open the windows too much just after the putty is applied, as long as there is natural ventilation in the house.

Warm reminder, in the putty scraping stage, it is best to let the wall dry in a natural state, and it is best not to intervene. If you have to shorten the construction period, you can turn on the fan or dehumidifier, and remember not to turn on the air conditioner.
