What should we do for solid wood flooring when it encounters the "millennium extreme cold"? Whether it's layers of fog or heavy snowfall in December and January, winter is always the peak season when solid wood flooring is prone to problems. Since the beginning of winter, various regions across the country have experienced strong cooling and rainy and snowy weather to varying degrees, which greatly increases the likelihood of problems with solid wood flooring in homes. Although we were very careful when cleaning the floor, we still inadvertently noticed that the floor had shrunk, deformed, or warped. Regarding this issue, the person in charge of Bijia Flooring, one of the "Top 10 Chinese Flooring Brands," told us that even if the flooring is installed firmly, it is still easy to occur in cold winter conditions. Solid wood flooring is "three parts paving, seven parts maintenance". In situations where weather changes cannot be controlled and the natural properties of solid wood cannot be overturned, proper and sufficient maintenance of solid wood flooring is the effective way to reduce the probability of problems with solid wood flooring. Due to the natural properties of solid wood, it exchanges moisture with the outside world. With changes in environmental temperature and humidity, solid wood flooring will experience expansion or contraction. If the range of expansion or contraction is too large, problems such as floor deformation, end cracking, and dry shrinkage joints may occur. Controlling indoor humidity and proper maintenance are scientific and effective methods to prevent deformation of solid wood flooring. Of course, this method is also applicable to reinforced composite flooring, multi-layer solid wood composite flooring, antique solid wood composite flooring, and underfloor heating flooring. Nowadays, many thermometers in shopping malls can display humidity simultaneously. Indoor humidity control within the range of 50% -70% is suitable for the human body, which is also suitable for the humidity environment of solid wood flooring. Internationally, it is stipulated that the relative humidity of the consumer's usage environment is 40% -80%. Only by controlling the indoor humidity within this range can the relative stability of the original characteristics of solid wood flooring be ensured. So, when blowing air conditioning at home in winter, it is important to pay attention to controlling indoor humidity and temperature. Bijia Flooring also suggests that when the humidity is below 40%, we can use a non dripping mop to mop the floor and directly humidify it, or use a humidifier to humidify it appropriately. Of course, solid wood not only has problems such as moisture deformation, but it may also be "poisoned". So when choosing a flooring brand, it is necessary to choose one that meets the national standard for formaldehyde emissions, and also to choose a brand with excellent quality. The top ten flooring brands such as Shengxiang, Bijia, and Nature are all feasible. A room with solid wood flooring should be regularly cleaned and kept ventilated.
