The cause of wood warping
If you notice, for any reason, that the surface of your wood has problems such as warping, swelling, distortion, or deformation, it's time to think about fixing it. But before anything else, you should know why wooden construction doors may be warped. Causes such as:
The desired door is located in an environment with bad weather conditions
The main reason that may lead to Wooden door warping is that it has been exposed to weather conditions. For example, this problem is probably more in the northern cities of Iran because there is a high level of humidity in these areas. Or, for example, a sudden decrease and increase in air temperature can damage the wooden texture of the doors. In the cold seasons of the year, the wood of the construction door shrinks and in the hot season, it expands. It is natural for wooden doors to crack or at best become warped in such conditions.
This is also true for wood products such as mdf.
The wood used in the door is of poor quality
Another reason that may lead to warping of the door is the low quality of the wood. As you probably know, different woods are used in the construction of building doors. Some of these woods are not of sufficient quality and their fiber connection is not strong enough. In fact, the main reason for the warping of the doors is that quality and resistant wood was not used in their construction.
The quality of these doors will be determined over time. For example, one of the doors that usually suffer from this problem are doors made of Russian wood. This wood will decrease in quality over time.
Failure to take care of building doors
Another reason that may end up warping the door is that the doors are not properly cared for. All wooden doors and doors made of wood products, if they are exposed to harmful factors such as water or sunlight, they become warped. Therefore, it is better to choose the desired door according to the environment conditions. The best humidity level for maintaining wooden doors is 8 to 10 percent.

The invasion of insects and corrosive creatures into the wood
One of the main places where insects and corrosive creatures can live is wood. In fact, the main enemy of wooden doors is the invasion of insects, which eventually leads to warping of the door. If ants, termites or carpenter bees penetrate into the wood tissue, after some time they can destroy the fiber connection of the wood. So if you know that your door has been attacked by these insects, try to destroy them immediately.
Failure to comply with the principles of preparation during wood processing!
You should know that many construction doors are currently made of industrial wood or wood products such as fiberglass, MDF or HDF. Therefore, if the basic principles are not observed in their construction, they will become warped very quickly. If the edges of wooden products are distorted, you can no longer prevent them from warping.

- The wood should never be left half dry. Rather, it should be dried to the right humidity.

Use an iron
One of the great ways to fix the Wooden door warping problem without damaging the door itself is to use an iron. To do this, cover the lid with wet towels. Do not forget that none of the parts of the door should be left without a towel cover.
Be careful to go for towels or fabrics that are resistant to the heat of the iron and do not get burned. Also, the moisture level of these towels should not be too high. It is enough that they are not visible.
In the next step, it is better to place the convex surface of the door upwards. Set the iron to its highest temperature. If you have a steamer, your work will be much easier. When the iron is completely hot, press it on the warped surface and drag it on the surface. Be careful that the level of pressure you apply on the door should be uniform.
Each time you press the iron, it is better to hold it for 5 to 10 seconds.
Don't forget to iron all parts of the door and don't just stick to the curved parts. If necessary, do the ironing step several times.
In the last step, open the towels around the door and let the door completely dry and cool.
Be careful that this method may not be useful for all wooden construction doors. So if you tried once or twice but did not get results, it is better to look for another method.

Use sandpaper
Another method that is used to fix wood warping and usually has a good response is using sandpaper. Of course, this method is difficult and complicated and may require professional help.
To do this, you need to remove the door from its frame and place it on a flat surface. Then sand the uneven surface. Of course, during this process, part of the door color may be scratched by the sandpaper. For this reason, it is usually necessary to have a painting operation as well.
Check the bumper and door lock
Sometimes the main reason for the door to warp is that the bumper and the door lock are not in the right place or they are not fastened together well. In this way, the door is slightly tilted and seems to be warped.
In such a situation, it is better to change the position of the bumper a little and then check the condition of the door again.
To do this, you must open the bumper first. Then, put the screwdriver in the upper holes and hit it with a hammer. The pressure caused by the impact causes the bumper to move slightly downwards and the problem of the door is also eliminated.
