What do you think about cracking of original wooden doors? Is it really a quality issue?

I have a friend who bought a raw wooden door for his home. Originally, the wooden door was solid, thick, beautiful and elegant, and could show his identity. However, after using it for a period of time, he found that there were some small cracks on the wooden door. Why? Will the door encounter cracking or deformation problems? Is there something wrong with the quality?

1. The original wooden door is cracked and has quality problems?

Many friends believe that if the original wooden door cracks, The original wooden door must be fake. In fact, this is not the case. Even if it is a real wooden door, cracking is inevitable. Even priceless rosewood furniture cracks when on display in the Forbidden City, and the Forbidden City needs restoration. Nowadays, almost all famous brands stipulate this in terms of after-sales service: It turns out that cracking of wooden doors is a natural characteristic, and it should be repaired as much as possible rather than replaced.

2. Three real causes of cracking of original wooden doors

Reason 1: Moisture content of logs

If the moisture content of the original wooden door is not well controlled, quality problems such as cracking and deformation will occur. After the door is made, the moisture content and drying stress of the wood determine whether the shape and material of the door will be re-opened. Therefore, it is very important to control the moisture content of the original wooden door. The balanced moisture content will not be affected by sunlight, overcooling, Cracking and deformation due to environmental factors such as overheating. The natural properties of the log curve determine its variability after the product is made. Wooden door companies cannot solve this phenomenon, but they can reasonably control it in some aspects. Cracked.

Reason 2: Weather

The moisture content of original wooden doors is required to be 1 to 2 percentage points lower than the actual average air moisture content. Due to the groundDepending on the geographical location, my country\’s climate and weather are also different, so the moisture content requirements for original wooden doors are also different. For example, the annual average moisture content in Beijing is 11.4%, so the moisture content of original wooden doors should be controlled at 10.4% or 9.4%; the average moisture content of air in the south is 14%, and in the north it is 12% to 13%. Therefore, some wooden doors produced in the south will crack after being shipped to the north, while wooden doors produced in the north will swell and cannot be closed after being shipped to the south.

Reason 3: Transportation damage

The original wooden door will inevitably be bumped during transportation, so be careful during transportation. Although original wooden doors are \”sturdier\” than doors made of other materials, it is difficult to avoid them if they are not properly maintained.

3. How to rescue a cracked wooden door?

If no cracks are found with the naked eye, it is easy to solve this problem. Use 502 glue to drip along the gap, and then gently scrape off the excess glue with a blade, but be careful not to damage the paint of the car door with the blade

If it is a small crack that has already opened, the treatment will be more complicated. We provide you with two emergency remedies for reference only.

1. Cut old books and newspapers into pieces, add an appropriate amount of alum and water to make a paste, carefully embed them in the gaps and wait for solidification.

2. Mix the white glue and sawdust evenly, insert it into the gap, and sand it with sandpaper after a day and night.

When choosing wooden doors , pay attention to the following points:

First: Choose qualified products from qualified manufacturers. Some wooden door manufacturers who have mastered the technical essentials have in-depth research and prevention not only on high temperature and high humidity climates and conditions, but also on more severe environments. .

Second: Pay attention to the thickness of the wooden door. The thinner and lighter the wooden door is, the better., the suitable thickness of wooden doors is 45mm, such doors are not easy to deform.

Third: Pay attention to the material of the wooden door. Use tapping to listen to the sound. The sound of good wood is mellow and textured.

Fourth: Pay attention to the paint craftsmanship on wooden doors, good paint The craftsmanship has good feel, luster and uniform color, and its strength and luster are comparable to the metallic paint of a car.
