Tongue and groove refers to the traditional method of a ‘tongue’ which juts out on one side of the board and an indented ‘groove’ on the other side. The tongue is designed to fit perfectly into the groove and creates a smooth, gapless result. The hardwood surface of the wood is untouched, and the visual appeal of the floor is not compromised.
Your premium quality flooring has been coated with a formaldehyde-free, UV lacquered finish, which is ready for installation and does not require any special treatment directly after installation. However, you should be aware that engineered hardwood flooring will naturally get worn; therefore some regular maintenance is recommended to protect and to preserve your floor’s beautiful surface:
Wood is a living material, which swells when moisture or humidity levels rise and shrinks when moisture or humidity levels fall. These not only show that your floor is a natural product but can also lead to some irreversible deformation of the floor if the room climate and humidity is left too high or too low for an extended period of time. This can particularly happen if, for example during winter, the relative humidity in a heated room falls below the specified 45%. In this case you should install an air humidifier in order to prevent damage to your floor. The same may also be necessary with an air-conditioned room.
