Additionally, many such floors are multipurpose. For instance, a community hall might be used for play groups and old-age groups, for dances, aerobics and sports, and for seating for plays. The floor may have to support heavy objects like pianos. There may also be requirements for ease of cleaning and maintenance. Cost of repair after damage by vandals or stiletto heels is also a consideration. Note that the necessity to serve multiple purposes can often be eased by the use of a gym floor cover to protect the floor.
