1、 Wet bulging arch phenomenon: the face of wooden floor is partially arched up, or some wooden floor is arched up.
Cause: the reason for this may be that the weather is too wet and cold, and the floor is to make moisture removal measures, resulting in the moisture in the air being absorbed and expanded by the wooden floor.
Preventive measures: open windows frequently for ventilation, and reserve structural extension joints, sectional joints and adjust the reserved extension joints between adjacent plates according to regulations. Solution: after the moisture content of the wood floor is balanced with the relative humidity in the air, it can be removed and repaved according to the situation, and the sectional joints and the reserved extension joints of the adjacent blocks can be adjusted.
2、 Floor cracking phenomenon: small cracks appear on the wooden floor, which can also cause the phenomenon of paint peeling.
Cause: climate change, wood floor moisture content is too high or too low, wood floor appears dry shrinkage or wet expansion, resulting in paint cracking. Or because of long-term exposure to the sun blowing, leading to shrinkage phenomenon.
Preventive measures: select good quality wood floor, the film adhesion, elasticity, wear resistance can be guaranteed.
Solution: a small amount of paint film cracking, can be repaired. If there is a large area of cracking, it can be polished and repainted. If only a single wooden floor cracks at the end of the period, the single wooden floor can be replaced.
Three. Sound phenomenon of walking wood floor: after the wood floor is paved, the walking will make creaking friction sound, or single sound extrusion burst sound, etc.
Cause: when paving the floor, the concrete base is not smooth, which leads to the reduction of moisture content of wood floor, the reduction of nail holding force of wood, and the loosening of keel installation.
Preventive measures: when laying wooden floor, it is necessary to check whether the concrete base is smooth. When the keel is paved, the larger the area contacting the concrete base is, the firmer the installation is. The more the cushion part is, the higher the cushion is, and the easier the looseness is.
