Should I close the doors and windows after the house is renovated? What is the purpose of closing the doors and windows after the house is renovated?

We all know that there are many things to pay attention to when decorating a house, whether before or after the decoration. Many people will open the doors and windows for ventilation after decorating the house, so that formaldehyde can be better removed. In fact, this is incorrect. Generally, the doors and windows should be closed after the decoration is completed. So why should the doors and windows be closed first after the decoration is completed? Let's take a closer look!

Should I close the doors and windows after the renovation?

It is generally best to close the doors and windows first, and then start opening the windows for ventilation after about a week.

1. First of all, the latex paint in the newly renovated house has not dried yet. If you open the window for ventilation immediately, it will speed up the drying of the latex paint. Isn't it better for latex paint to dry faster? In fact, it is not. The characteristic of latex paint is to let it dry naturally. Opening the window for ventilation will play a role in weathering.

2. Latex paint that is ventilated with windows open is prone to peeling, cracking, and bubbling in the later stage. The correct approach is to close the windows for a few days to let it dry naturally.

3. The reason why everyone is so anxious to open windows for ventilation is simply to remove formaldehyde as soon as possible. In fact, if the formaldehyde content in the home exceeds the standard, just opening windows for ventilation will not be effective. The only way to prevent the formaldehyde content from exceeding the standard is to start with the decoration materials. Among the decoration materials, the materials that are likely to cause formaldehyde content to exceed the standard include paint, wood boards, wallpaper glue, etc. Therefore, when purchasing decoration materials, you must ask the merchant to provide the product's factory inspection report and purchase it from a qualified store.

What is the purpose of closing doors and windows after renovation?

Protect decoration

The house has just been renovated, and many new materials are in a damp and unstable state. For example, newly painted latex paint, wallpaper, and some glass glue, etc., need to be naturally dried before they can be exposed to the outside environment. If you open the window directly, dust may be blown on it, affecting the appearance and may also damage the wall. Too dry or too humid wind is not good.

Accelerate formaldehyde discharge

The main reason why people are eager to open windows for ventilation is to expel harmful gases such as formaldehyde produced by decoration. The higher the temperature, the more active the formaldehyde is and the faster it evaporates. Therefore, the newly decorated house should be kept sealed for two days to increase the indoor temperature, and then open the windows for ventilation. This will help to expel more formaldehyde gas faster. Formaldehyde pollution is the most common problem in decoration, and the most effective and simple way is to open windows for ventilation.

Reasons for closing windows after renovation

1. Most customers use latex paint for home decoration, but after the decoration is completed, some latex paint has not dried yet. If you open the windows for ventilation at this time, the latex paint will dry quickly; in fact, this is a wrong method. If you open the windows for ventilation at this time, it is very likely to cause the latex paint to crack, bulge and fall off, which is what we call latex paint weathering.

2. After the wallpaper and wall cloth are installed, it is also recommended to close the windows and doors for about a day; this will allow the glue in the wallpaper and wall cloth to dry naturally without weathering.

3. The main thing is to ensure that the air in the room is not circulating, and the moisture will not be carried away by the air or temperature, so as to ensure that our wall and floor decoration materials dry naturally, so as not to waste our hard-earned money, and at the same time, it can also achieve better decoration effects.
