Wallpapering the walls during repairs is not the most difficult job, it can be done in a few hours with certain skills. But it requires skill and knowledge of the basic techniques and rules.
Quite often, while gluing walls, you can make minor mistakes, but they will nullify all efforts. For example, this applies to drafts.
It will be a mistake to ventilate the room immediately after all the work performed. You need to know that you need to withstand a certain period of time.
Microclimate
Before gluing the wallpaper, the microclimate of the room should be brought to optimal values.
The temperature should be in the range from +15 to +25 degrees. At higher rates, the glue will dry out very quickly, and high-quality gluing will not work, since you need to constantly glue dry strips and coat the walls again.
Humidity should be at least 50%, and it is better if this figure is raised to 60%. If you are doing repairs in the summer and the air is too dry, then you need to spray water from a spray bottle to humidify the room.
When the windows are located on the sunny side in the room, you can hang a curtain so that the space does not warm up to too high a temperature.
Important! Windows and doors should be kept closed during and after gluing.
How long does wallpaper dry
Different types of wallpaper require a certain amount of time to dry completely.
After sticking paper wallpaper - it takes a short time. In this case, the windows can be opened a day after the completion of work.
Paper based vinyl wallpaper dries in 36 to 48 hours. At this time, you need to open the door as little as possible, not to mention the windows. They must be kept closed for the entire period.
Vinyl on non-woven base dries even longer. They need from three days to a week. Forced drying is better not to use, as there is a chance to spoil your work.
Attention! It is necessary to allow the canvases to dry naturally, without the use of artificial heating or ventilation of the room.
Special care should be taken when gluing non-woven wallpaper for painting. They are allowed to dry for a week before starting to paint, as not completely dry wallpapers, under the weight of their weight and the weight of the paint, can simply slide down the wall.
Non-woven types are usually not a cheap wall covering, so you need to treat them after gluing with special attention. You can not often open the door, chasing air, changing the temperature and humidity of the room, and the windows must be constantly kept closed.
Why you can't open windows
While wallpapering, the windows must be kept closed, since the rapid drying of the glue leads to peeling and unnecessary work on gluing the loose joints, and possibly the entire strip as a whole.
This is especially true of paper and non-woven wallpaper. Vinyl is less sensitive to changes in temperature and humidity, but it also reacts negatively to open windows and doors. It is necessary to close windows and doors for the entire period of drying of glue and wallpaper.
Drafts and sudden changes in temperature can cause blisters to appear on the wall surface, the canvases to partially come off or the piece to peel off completely.
In some cases, the work will have to be completely redone, and the peeled off wallpaper will be unsuitable for new gluing and the material must be purchased again.
Windows must be kept closed for at least 2-3 days. For some species it is better not to open even more.
Glue drying time
It is also necessary to take into account the drying time of the glue. Quick drying formulations are currently being produced. But they must also be dried for at least 36 hours in a room with normal microclimate indicators, and in some cases up to 48 hours.
Wallpaper should dry evenly in natural conditions, so do not turn on heating devices or arrange artificial ventilation.
Important! If repairs are made in the summer, and the temperature difference is not critical, then vinyl, and sometimes non-woven wallpaper, experts allow gluing with open windows.
After watching the video, you can understand why it is impossible to open windows and doors during gluing and for some time after it:
Wall preparation
When preparatory work is underway for gluing, the windows are not only possible, but also necessary to be kept open.
It is necessary to clean all surfaces from former coatings - wallpaper, old glue or paint, putty cracks, remove all bumps on the walls. The putty must dry completely, after which the surface must be sanded with fine sandpaper.
Clean the walls of dust by brushing or collecting it with a vacuum cleaner. After that, apply a primer. It provides better adhesion of the wallpaper to the wall. The primer can be prepared by yourself from the purchased wallpaper glue. It must be diluted with water, taking two to three times more liquid than for preparing an adhesive solution.
It is necessary to coat the wall carefully, without gaps, otherwise the wallpaper may peel off at the joints, from above or below, or the entire canvas may peel off. How well the wallpaper will adhere to the wall depends on a well-primed surface.
Correctly and how well prepared the walls can be checked in a simple way: you need to cut off a strip of electrical tape and stick it on the wall. If, when removed, there are no small particles of plaster left on the tape, then the surface is ready. Wallpapering of walls is carried out only on absolutely dry walls.
What happens if you open windows immediately after wallpapering is shown in the photo:
If the room is equipped with an air conditioning system, a controversial question often arises: is it possible to turn on the air conditioner with the window open? Some open the window and say that it can be done, the second, on the contrary, close all windows and doors and repeat - in no case should this be done! So who to believe? Information about the operation of the air conditioner and an objective judgment will help to understand the issue.

What temperature is considered comfortable for the average person?
A person begins to feel chilly and cold during the cold, and during the heat - to sweat and overheat. At the same time, the ability to work decreases, and during overheating, heat stroke can occur. To prevent this from happening, it is necessary to maintain a temperature regime that is comfortable for the human body from 18 to 25 degrees Celsius.
If in the winter time heating devices help to warm the living space, then in the warm seasons the air conditioner copes with this task.
How does an air conditioner work?
Air conditioning systems can be conditionally divided according to the principle of operation into three types:
- The supply type of air conditioning uses air that is not in this room (or outside).
- Recirculating type - uses air only indoors.
- Recuperative type - can use the air both from outside and inside the room.
All types of air conditioning systems are united by a common mechanism of operation - for cooling, air passes through the system with a cooler. Freon gas is used as a coolant.
Note! The main reason why you want to open a window when the air conditioner is running is the flow of fresh air into the room. Simple air conditioners do not provide this, but this is feasible with air conditioning systems with supply and exhaust ventilation. The supply system supplies fresh air to the room, and the exhaust system removes polluted air from it. But these solutions have a corresponding price.
Open the windows with the air conditioner on. Causes and consequences
Modeling this situation would lead to the following conditions:
Important! The temperature regime is important to observe in the case of refrigerators. An explanation about this is given by the article: "Is it possible to put hot food in the refrigerator."
Will the air conditioner break when the window is on?
The main reason for the breakdown of air conditioners is water hammer. It can appear for several reasons, among which are quite frequent:
- Low temperatures. When the temperature in the room is below zero, the air conditioning system can quickly fail. Of course, few people will open the windows so that the room has a sub-zero temperature, but this must be remembered.
- Clogged filters. The main and quite common reason mentioned above. Polluted "dusty" air from the window can quickly "break" the air conditioner.
Advice! Dust causes windows to become dirty. Learn how to properly clean windows without streaks.
Prolonged operation of the air conditioner with the window open can lead to rapid wear of the compressor and fan.
Advice! If you need to bring fresh air into the room, briefly open the window for ventilation, and turn off the air conditioner. Then close the window and turn on the cooling device again.
In conclusion, I want to say: you are the owner of your equipment and it is up to you to decide how to dispose of it. Air conditioning engineers advise not to open windows while operating this equipment, so as not to void the warranty, reduce service life, or break the air conditioner.
Summertime (especially in the southern regions) can raise temperatures up to + 35, +40 degrees Celsius. Cars with such indicators simply heat up (even if they are not in the sun). How to properly cool the interior of the car? Ventilate or turn on the air conditioner? Or can you open the windows when the air conditioner is on? Let's figure it out? As usual there will be an article + video version ...
There are only a few persistent myths, for example:
- Do not open windows if the air conditioner is on - the latter will break
- Do not open when the cooler is running - because you can get sick
- Open windows use MUCH less fuel
Here, as usual, there is some truth, there are pure myths - let's figure it out.
What should be done?
At the very beginning I will tell you how to do it. If the car is very hot, then you can first open all the windows (or at least the front ones) and drive a few hundred meters there, the oncoming air flow will cool the interior. Excessively heated air will come out of the car - then you can already close the windows and turn on the air conditioner, it will come to its power so corny faster and cool the interior faster.
This is the best way to cool the interior in the heat. It doesn't matter what you have installed, air conditioning or climate control
However, not many do so.
The air conditioner will break - if you open the windows?
Why did so many on the net take this? Why should it break, for what reason? It has worked and will continue to work - it’s just that the energy that goes into cooling the cabin will go to waste.
When you open the windows, cool air will simply fly out the window, and warm air from the street will come in its place.
BUT the air conditioning system worked and will continue to work normally.
If you have climate - control, in the "AUTO" mode (it has a temperature sensor), it can add momentum and will work at full power, trying to catch up with the desired temperature.
However, no damage will occur. The air conditioning system is designed for such loads, withstands them without problems.
So if you want to ride with air conditioning and open windows - RIDE, but there is VERY LITTLE sense in this!
If I open the windows, I'll get sick!
There is such a myth - supposedly cold air from the cabin, mixed with hot air from the environment and all at once a disease.
Is this not clear to me at all? For example, it is + 30 degrees outside, + 22, +23 degrees in the cabin, even if you open the glass, mixing will occur - cold air will come out and warm air will come in, nothing bad will happen. What do you get sick from? YES, and the difference is only + 7 degrees, this is not critical.
You can get sick if you lower the temperature inside the cabin too much, for example, to + 18 degrees and direct the air duct nozzles towards yourself. Sit down hot and there is such an icy air, almost 100% that you will get sick.
It is also worth cleaning the air conditioning system every year (well, at least two years), changing the cabin filter (I advise at least once a year, I personally change it twice a year) - after all, a lot of garbage and all sorts of bad things settle in these systems, up to mold. And then we breathe it, it is this that can provoke various diseases, such as colds.
Increase in fuel consumption
When you turn on the air conditioner (or climate control), some write that fuel consumption increases. This is logical, open windows to ventilate the interior and save money. It's not always worth it! Why?
- Consumption increases by an average of 1-3% under various driving conditions. The slower you move, the less it grows
- On the highway, you may not notice the savings at all, when you are moving at speeds of more than 60 - 70 km / h and the windows are open, a parachute effect is created, which also slows down the car. It turns out that again the same 2 - 3% is spent on this effect, of course this is not comparable with the air conditioner consumption, but it is growing.
Of course, if you are in traffic jams, the expense will be higher here, because you have to pay for comfort. But on the highway there may not be any savings at all
Now a useful video version, watch
In conclusion, is it possible to open the windows when the air conditioner is on? Of course you can, why not? Nothing breaks and you don't get sick. I personally don't see the point in doing this. Because the cold air will evaporate very quickly, and you will waste the energy that was needed for cooling.
Personally, I always move with climate control, my air is directed to the windshield and legs, the cabin windows are closed, usually the temperature is set to +22 degrees Celsius. Very effectively saves from almost any heat.
Using the air conditioner, you can hear that the windows must be closed at the same time. At the same time, some continue to open windows, while arguing that in this way it is possible to ventilate and cool the room faster. It is worth understanding the problem and understanding whether it is worth turning on the air conditioner with the windows wide open?
Increase in air volume
Experts say that with open windows, the volume of air in the room increases significantly. The air conditioner, which at this time cools the air in the room to a certain temperature, is forced to spend more energy and time on cooling the constantly increasing volume of air mass. At the same time, already cooled air will go out the open window, warm air, in turn, will again enter the room. Such air exchange negatively affects the operation of the air conditioner, which constantly increases its power in order to maintain the set temperature. You should also not ignore the unjustified consumption of electricity, which goes to the enhanced operation of the air conditioner, since, in turn, this will lead to unjustified financial expenses.
Rapid clogging of filters
Another reason why it is not recommended to use the air conditioner with the windows open. Air conditioners have filters that tend to get clogged from time to time. Manufacturers recommend cleaning the filters from time to time to avoid problems and interruptions in the operation of the cooling unit. An air conditioner running with the windows open runs the risk of clogging the filters much faster. Which can damage the device.
The risk of catching a cold doubles
Almost everyone knows that under the air conditioner you can easily catch a cold, and therefore they try to stay away from the device at the time of its operation. Also, with open windows, they try not to sit in a draft, as you can imperceptibly harm your health. With the windows open and the air conditioner turned on at the same time, the risk of catching a cold from drafts doubles, so those who practice simultaneous ventilation and cooling often suffer from colds and complications caused by respiratory diseases. Experts recommend cooling the room with air conditioners only if necessary, since, in addition to a cold, you can also earn allergic complications.
Most indoor air conditioners can only reduce the temperature, but they do not supply fresh air. As a result, in rooms where there are many people, there is sometimes a lack of oxygen, which provokes a state of suffocation. That is why many are interested in whether it is possible to open windows while running. The relevance of this topic is also determined by the results of the experiment, that if the windows are closed and the air conditioner is on for a long time, then an excess of carbon dioxide occurs in the room, and this, as you know, is harmful to the general condition of the body. That is why it is worthwhile to understand this situation in as much detail as possible, taking into account all the nuances.
Why can't you turn on the air conditioner with the window open?
If the cooling technique is working, then an open window not only opposes the cooling of the room, and sometimes even makes it pointless, but also causes several negative consequences that cannot be ignored.
Why you shouldn't open windows when the air conditioner is on:
- The volume of air in the room increases, which means that in order to reduce its temperature, the equipment has to work in an enhanced mode, spending more time and energy on cooling the room. In addition, the cooled air goes outside, being replaced by warm air. This mode of operation negatively affects the condition of the air conditioner, and also increases energy consumption, which will affect utility bills.
- Operating with an open window, the air conditioner becomes clogged much faster. To avoid equipment breakdown, you will have to clean the filters more often than usual. This is due to the fact that when the window is open, a large amount of dust, pollen and other debris enters the room. As a result, the air conditioner does not work as efficiently and the air in the room itself is also polluted.
- Many people know that if you sit under the air conditioner for a long time, you can catch a cold. Scientists have proven that the operation of the air conditioner with open windows significantly increases the risk of developing the disease, since in such a situation it will not be possible to avoid drafts. This is especially dangerous for children.
From this we can conclude that air conditioning and an open window in a room are two incompatible concepts. It is best to ventilate the room several times a day, but the equipment must be turned off. In this case, you will receive cooled air saturated with oxygen.
