Many consumers will have such doubts:
Why is the color of the floor at home different from when it was first installed?
Some even think that the quality problem has repeatedly found the merchant accountable, and the merchant is suffering no matter how to explain it, and cannot convince the consumer, so it is very depressed.
So why does the newly paved floor change color?
The reason for this problem can be explained from the following aspects.
1. Internal factors
The discoloration of wood is mainly caused by the absorption of ultraviolet light. The sapwood and heartwood of wood have different degrees of discoloration after absorbing ultraviolet light, which will cause a certain color difference in the paved floor.
The wooden floor is natural wood, which possesses the natural properties of wood, and the resulting light discoloration is normal and not a product quality problem.
The color change reaction of most woods is from light to dark, and only a few woods are from dark to light. The color change on the same floor is basically the same.
Therefore, the paved floor should not be exposed to sunlight for a long time, and the necessary shading measures should be taken appropriately.
2. External factors
Before the geothermal floor paving, the moisture content of most floors is around 20%. During the floor paving process, if the moisture-proof film is damaged, a large amount of moisture will enter the floor from the damaged area during geothermal heating, resulting in a rapid increase in the floor moisture content The dissolution of some soluble substances and the effect of some color-changing bacteria cause the wood to become exhausted or blue. In some cases, in wet areas such as toilets and kitchens, the influence of external moisture can also cause the floor to become discolored in some places.
3. Pavement factors
The above-mentioned discoloration of the floor occurs in the wet area of the floor. The interface between the discolored area and the uncolored area is very obvious, and it is continuously distributed among several floors. There are also some discoloration of the floor that are caused by the pavement.
1. The ground is uneven, and there are small pits with unevenness. After the floor is paved, the moisture-proof film is broken by the pad, causing ventilation. Therefore, scrape the ground before installing the floor.
2. When paving, there are sand particles on the ground, which are not cleaned, and the moisture-proof membrane pad is broken, resulting in ventilation. Therefore, clean the ground before paving.
3. The connection of the moisture-proof film is not sticky during paving, which causes ventilation. The moisture-proof film should be tightly taped, preferably plastic tape with a width of more than 60mm to ensure that the moisture-proof film is not breathable.
4. Geothermal heating is used in the area. Some users turn on the geothermal equipment and adjust the indoor temperature to 27 ～ 30 ℃. The surface temperature reaches nearly 100 ℃ in a short period of time, causing damage to the moisture-proof film, producing ventilation, and discoloring and deforming the floor.
This violates the requirements of geothermal heating (surface temperature controlled at around 40 ° C).
5. When the floor is paved to the connection with the wet interface, such as: toilets, kitchens, shaded balconies, etc., the moisture-proof film should be returned upward, and the edge of the floor should be wrapped with the moisture-proof film to prevent moisture from entering and reducing and avoiding this area The discoloration and deformation of the floor.
Tips
The cause of the discoloration of the floor is not related to the quality of the floor itself.
In order to avoid this situation, the floor should not be exposed to sunlight in the usual time, pay attention to moisture, and the surface temperature should not be too high when using floor heating, it should be controlled at about 40 ℃.
