Why do you need to close the doors and windows after the renovation? What is the purpose of this?

After the renovation is completed, the main purpose of closing the doors and windows for the first time is to purify the air and release formaldehyde. During the decoration process, many materials used such as paints, adhesives, and man-made panels will release harmful substances such as formaldehyde. These harmful substances can accumulate in a closed environment and pose a threat to human health.

Therefore, after the decoration, it is necessary to close the doors and windows tightly to allow formaldehyde and other harmful substances to be released quickly in a closed environment.

With the decoration device, you only need to enter the area + city, and calculate the most affordable local market in 3 seconds**: [Tuba Rabbit Big Platform Counts**].

No longer worry about the company's price increase, omission and price increase.

In the Chinese market, the cost of formaldehyde testing and treatment ranges from a few hundred to several thousand yuan, depending on the size of the house and the complexity of the treatment. If it is a newly renovated house, it is recommended to carry out formaldehyde testing and treatment within 1-3 months after the renovation is completed to ensure the safety of the living environment.

At the same time, closing doors and windows can also help protect newly renovated furniture and decorations from dust and moisture, extending their lifespan. For a period of time after the renovation is completed, it is recommended to open the windows regularly for ventilation to help the emission of harmful substances such as formaldehyde and keep the indoor air fresh.

In general, closing the doors and windows after renovation is to protect human health and protect newly renovated furniture, but also to keep the indoor air fresh. After the decoration is completed, formaldehyde detection and treatment should be carried out in time to ensure the safety of the living environment.

Because it is necessary to protect the construction effect, the purpose of this is to prevent weathering of the renovation project and promote the release and discharge of formaldehyde.

After the house is renovated, the doors and windows should be closed tightly for 3 5 days, which is a buffer period, after this buffer period, the window can be opened for ventilation, the main reason for this is to protect the construction effect, because most houses have to brush latex paint and scrape putty when decorating, these raw materials are liquid, it takes a while to completely dry after brushing to the wall, and the same is true for wallpaper. If the windows are opened for ventilation as soon as possible after the construction is completed, it is not conducive to the drying of these construction projects, which will affect its decoration effect, and will also shorten the service life of latex paint and wallpaper.

After the decoration, close the doors and windows in time to maintain the stability of the indoor environment, prevent the humidity from being too high or too low, because the air is too dry or moist, which is not conducive to the drying of wallpaper and latex paint, which will reduce their service life, and will make latex paint and wallpaper appear peeling and cracking and other uncomfortable symptoms, close the doors and windows for 3 5 days, let him dry in a natural environment, and will maintain a better decoration effect.

It is conducive to the release of formaldehyde, and it is also an important purpose for people to close the doors and windows after decoration, because formaldehyde is a harmful gas to the human body, and opening windows for ventilation can reduce the concentration of formaldehyde in the air.

In addition to decoration plates, latex paint and adhesive and other decorative materials contain formaldehyde in the decoration process, formaldehyde may also exist in wallpaper curtains and other items, and its play point is 19 degrees, the higher the temperature, the more conducive to the volatilization of formaldehyde, below this temperature formaldehyde can not volatilize, so the joint doors and windows maintain a relatively high temperature and humidity, which is conducive to the release of formaldehyde in decorative materials. After four or five days, the closed doors and windows will be opened, so that the indoor air will circulate, and the fresh air from the outside can enter the room, which is the concentration of indoor air enhancement will also be significantly reduced.

This is because all the materials are not very stable after the decoration is completed, and the doors and windows can be closed to make the room better dry; The purpose of this is to keep the room dry and better protect the cleanliness of the house.

Formaldehyde as a low boiling point of the substance, its volatile point is about 19 degrees Celsius, if the doors and windows are closed, then the indoor temperature will gradually rise, which is more conducive to the volatilization of formaldehyde, and the indoor formaldehyde content will decline faster.

However, it is not possible to blindly close the window, and the window closure and window opening should be effectively combined.

In this way, the phenomenon of differentiation can be avoided, and the rapid drying of the object can be avoided, which will cause the fission of the house; This is done to keep the house from drying out too much and to prevent cracks in paint, emulsion, etc.

1. Prevent damage to the wall.

The house that has just been renovated, because many materials have not been completely absorbed and condensed, and the house that has just been renovated, and I don't live in it, if it rains, the rain from the window can easily make the floor or wall and background wallFurniture such as paint is damaged, and our new house is flawed, and we must be unhappy to live in it, so we have to close the windows and close the doors so that this does not happen.

2. Windproof.

We close the door and close the window, mainly weatherproof, now there are many decoration materials, such as floors, wall tiles, as well as background wallpaper, curtains, ceilings and other materials are very afraid of differentiation, for example, the wallpaper before the wallpaper is likely to be useless is glue paste harmful to the human body, but now the wallpaper with glue are plant gel, this gel if the coagulation time is longer, is healthy and pollution-free,If you open the door, the moisture in your glue will be air-dried and the adhesion will be ineffective, resulting in wrinkles or deformation of the wallpaper. If we close the doors and windows, the wind comes in from our house, and this will not be the case.

3. Keep the soil moist.

We decorate the house usually with cement mixed with sand, and then with easy cement decoration, this is the use of moisture to increase the degree of solidification, close the doors and windows can make better to maintain the suitability of concrete, easy cement is used to solidify the house decoration finished. We must make sure that the entrance window will keep our room moist and make our house more solid.

After our house is renovated, we must pay attention to the windows and doors, we must let the decoration materials inside solidify, and we can also open the windows and doors, so that the house we decorate will be more solid and beautiful.

Closing doors and windows not only allows the latex paint to dry out, but also helps better with formaldehyde emissions.

If it is winter you need to close the doors and windows to let the walls dry.

I haven't heard of this saying yet, anyway, after the renovation of our house, we opened the windows directly, and there was nothing wrong.

I haven't heard of this statement, we opened the windows directly after the renovation here, nothing happened, some claims to remain skeptical.

The north is going to be like this, but the south is fine, and you can open the windows directly after renovation, because the south is very humid and not easy to crack.

Maybe the paint in the house hasn't dried yet, or the paint on the furniture hasn't dried, and you have to wait until it's all dry before you can open the window and let it out.

Closing doors and windows will make the indoor temperature rise, and when the temperature is high, some formaldehyde can also be removed.

It is to make the floor and walls inside the house dry, otherwise the walls will crack. The ground will also bulge.

It cannot be ventilated, but it cannot be opened. This will not serve too well and will damage the decoration. Here's my 511 ventilation method, which works especially well in the hot summer.

No matter how hot it is, close the windows from Monday to Friday, and the room will be stuffy, the hotter the better, and it will be stuffy for five days. Open all windows on Saturday morning, ventilate, if there is no natural wind, turn on the ** air conditioner with a floor fan, increase air convection, expose all charcoal packets to the outside, close all windows at night, and repeat Saturday's work on Sunday. Moreover, repeated once a week, formaldehyde can be quickly volatilized, and the windows are opened frequently, and sudden bad weather will not cause damage to the decoration.

The biggest benefit of closing doors and windows in a newly renovated house is that indoor formaldehyde can be released quickly. In the case of high temperature and solar terms in summer, you can move in 5 or 6 times every 6 days by closing the doors and windows every time you close the doors and windows. If it is a winter method, the air conditioner should be turned on indoors.

If you renovate the house and ventilate the house, formaldehyde can exist for 10 to 15 years. It's like an obese person** who chooses to go for a walk every day. That will take a long time.

If you keep running every day, I believe it will have a one-month effect. **Sweat burns body fat through exercise. The same goes for the house.

In addition to formaldehyde, sweat at home first. Why should you close your windows in the summer? The indoor temperature rises, the formaldehyde stuffiness in the walls and furniture rises, the temperature rises, so stuffy for 5 or 6 days, and then open all the doors and windows, ventilate for a day, and the fan can be used in the poorly ventilated places, and it is almost not a problem to repeat five or six times, in addition to not using granite at home.

Because granite contains radioactive materials.

I've been a painter for 25 years. This experience is something I have summed up over the years. My method has been uniformly qualified by the second-level authoritative inspection agency in Shanghai.

Among them, the house that I bought for 10 years did not detect excessive formaldehyde after I renovated it, but the granite that was used for 10 years exceeded the standard value at that time. Let me first explain this phenomenon to you. This phenomenon is what we often hear about weathering.

Much of the sand in the desert is weathered. We see that the sand is very dry and all powder, and this is the result of weathering. Wind energy quickly robs objects of moisture, causing them to dry quickly.

Why do you say Fenghua? Because the principle of weathering also applies in my home. For example, my house has just been wallpapered, and when I open the window, it will be very windy.

If the wind is strong, the moisture in the wallpaper will be quickly pumped out, causing the wallpaper adhesive to shrink, and the final result is that the pasted wallpaper swells and wrinkles, and even opens the glue and falls off. Therefore, after the renovation is completed, the doors and windows are closed for a period of time to prevent this weathering phenomenon. It is not to let the indoor air flow, and finally realize the natural drying and solidification of our wall decoration materials.

Achieve the highest decorative effect.

After decoration, close the doors and windows, so that the moisture in the interior decoration materials can evaporate slowly as much as possible, mainly to protect the decoration and avoid drying through quickly, resulting in a series of common quality problems. The windows can be fully opened for ventilation at least three weeks after the renovation of the new house has been completed.

If it is a freshly painted wall, it is not dry through, and if the window is opened for ventilation, the wall is easy to crack.

If the wind blows, it will cause cracks on the wall, so you need to wait for it to dry naturally.

Because the things that have just been renovated have not yet fully solidified, they cannot be blown directly, and if they are blown directly, the decoration may be ruined.

In this way, the style of the decoration can be protected, and the furniture will not be damp due to wind or rain, and this is also the right approach.

Why do you have to close the doors and windows after renovation? The details are too small to ignore! If you get it wrong, it's too late.

When the new home is decorated, the process of treating the base layer on the top surface of the wall, and the process of paving the wall and floor tiles all need to use a lot of water, which is dry on the surface, but it is not completely dry, the latex paint film has not been fully formed, and the cement mortar under the floor tiles has not been completely dried thoroughly, for the following reasons: just like an obese person who wants to choose to walk every day, it takes a long time to do it, if you insist on running every day, I believe that a month will have an effect, and you must rely on exercise and sweating to consume body fat. It's the same with the house, in addition to formaldehyde, the first thing to do is to make the house sweat and <>

If we decorate our homes, we will know such a phenomenon. Many decorators (here mainly refers to the oilman master) will give us advice after the renovation, let us not open the doors and windows for the time being. So many friends wondered, wouldn't opening the window disperse formaldehyde faster?

Indeed, after the renovation, you must close the doors and windows for a few days before opening the windows, but you can't open them for a long time. Windows can be opened during the day and closed at night. However, if the preliminary work is done well, it can also be ventilated.

New house decoration, the first thing we do after buying a house is decoration, decoration is not easy and the cycle is long, even if you invite a professional decoration company and team, but some details of the decoration still need to communicate with yourself, of course, the decoration completed by yourself will make people more satisfied, happy. Why, because the house has just been renovated, in fact, the newly built walls, the putty and latex paint that have just been approved, including the freshly made ceiling, furniture cabinets and other materials are not completely dry, volatile and clean, are still in the stable period, and it takes a period of time when the temperature difference is not large, and the temperature is relatively uniform to make the latex paint

It is the right thing to do to close the doors and windows after the renovation. If the window is opened for ventilation at this time, the humidity in the room will be changed, and the curing reaction time between the building materials and the base layer will be too short, resulting in insufficient bond strength, causing hollowing and blistering. A few years ago, I watched my relatives, friends, and colleagues buy new houses, and I was so envious!

Looking at the old community I live in and the savings in my bank card, I can't make up my mind. Looking at the housing prices going forward vigorously, as some people say, the money earned is not as fast as the housing prices.
