Leave it inside the room it will be installed in, with the boxes open, for at least five to seven days. This way the floor gets used to conditions in the room before it is used. In rooms where there are extreme humidity issues, it may be necessary to install a system such as a humidifier or a dehumidifier to control the environment in the room.
Also, there are many tropical wood species that evaporate moisture at faster rates than domestic species. Also, the resins and oils in tropical woods can interfere with moisture content readings, which can make it difficult to determine if it’s time to acclimate them.
The rule of thumb is to keep relative humidity between 30 and 50 per cent year-round. The temperature should be kept between 60° and 80° Fahrenheit. There are geographic exceptions to these guidelines, so ask your flooring professional and check product specifications from the product guide for further assistance.
