Wooden floors are favored by consumers due to their aesthetics, warmth and practicality, but due to improper construction and temperature conditions, wooden floors will swell and arch during use. What causes the problem? How to solve these problems? The editor will learn about it with you.
The solution to the wet swelling and arching of wooden floors
Problem:
Surface phenomenon:
Wood floor panels are partially arched upwards, or some wooden floors are arched upwards.
Cause analysis:
1. Continuous rainy weather, the relative humidity in the air is high, and no moisture removal measures are taken. The moisture in the air is absorbed by the wooden floor and then hygroscopic expansion;
2. The wooden floor is hygroscopic expansion after being immersed by the water;
3. The house is closed for a long time, uninhabited, poor ventilation, and the medium moisture in the paint layer has nowhere to evaporate after being absorbed by the wooden floor and then hygroscopic expansion;
4. The moisture content of the base concrete is too high, and the moisture-proof isolation layer is not sealed and hygroscopic expansion;
5. When paving wooden floors, no extension joints are reserved as required, and after being moist air, it absorbs and expands arches, and even the paint surface is cracked;
6. The paving area of the wooden floor is large or wide, and no segmentation measures are taken.
Preventive measures:
Open windows frequently for ventilation; and reserve structural extension joints, segmented joints and adjust the reserved extension joints between adjacent plates according to regulations.
Solution: When
does not affect the use function, you can wait for a long time to balance the moisture content of the wooden floor with the relative humidity in the air, and adopt a dismantling and repaving plan as appropriate; or dismantling and repaving all, adjust the segmented joints and adjacent plates to reserve extension joints.
