The wood floor for sports has the following advantages: 1. beautiful appearance, 2. comfort and 3 safety. However, the wood floor for sports also has the following disadvantages: 1. the wood floor for sports cannot be exposed to moisture because of being made of pure wood, so the ground shall be kept dry, and the wood floor for sports is prone to bulking and deformation if exposed to moisture. 2. The wood floor for sports cannot be directly exposed to sunlight, and the wood floor of any kind cannot be radiated by direct sunlight, which easily results in the expansion of the wood floor for sports to crack. 3. The wood floor for sports are vulnerable to termites, and in the case of high moisture content or in a humid environment, the wood floor for sports are prone to termites and will be eaten, which further accelerates the decay and damage of the wood floor for sports. 4. The cost of daily maintenance is high; in summer, the air humidity is high, and the gymnasium needs regular ventilation to ensure the balance of indoor air humidity; in winter, the gymnasium shall be regularly ventilated through a ventilating fan, and doors and windows shall be closed in rainy and snowy days to prevent rainwater from infiltrating the gymnasium through window seams to damage the wood floor; and in summer or in the intense sun, the curtains shall be drawn to protect the wood floor for sports from the sun, and the cleaning workers shall clean the wood floor for sports at least twice a day to treat the water stains on the wood floor for sports in time.
