What are the reasons for the solid wood floor to swell and arch?

One of the most common problems of solid wood flooring is the wet expansion of the arch, which is mainly manifested in the partial upward arching of the wood floor surface, or the upward arching of some pieces of wood flooring, so what are the reasons for the wet expansion and arching of the solid wood floor? Peace of mind flooring gives you a distraction analysis. Cause Analysis:

1. In continuous rainy weather, the relative humidity in the air is high, and no dehumidification measures are taken, and the moisture in the air is absorbed by the wooden floor and then absorbs moisture and expands; 2. The wooden floor is hygroscopic and expands after being flooded; 3. The house is empty for a long time, uninhabited, poorly ventilated, and there is nowhere to emit after the medium moisture of the stucco layer evaporates, and is absorbed by the wooden floor after moisture absorption and expansion; 4. The moisture content of the base concrete is too high, and the moisture-proof isolation layer is not sealed and the moisture absorption expands; 5. When the wooden floor is paved, the extension joints between the adjacent plates are not reserved as required, and the moisture absorption expands and arches after being exposed to humid air, and even the paint surface is squeezed; 6. The structural expansion joints between the wooden floor and the wall are not reserved enough; 7. The installation area of the wooden floor is large or wide, and no sectional measures have been taken. Precautionary measures: In fact, the occurrence of these situations is due to the failure to take preventive measures at ordinary times.

In ordinary life, according to the weather conditions, you can often open the windows for ventilation. When cleaning hardwood floors, do not use a wet mop. Solution:

The problem has come out, and the owners should not blame themselves too much or be angry, the key is to solve the problem. Under the condition that the use function is not affected, it can be left for a long time, and after the moisture content of the solid wood floor is balanced with the relative humidity in the air, the dismantling and resurfacing scheme will be adopted according to the situation; Or disassemble and resurveil them all, adjust the segmented joints and the reserved extension joints of adjacent plates.
