Hi guys, after a hiatus from this forum I've come back to ask for advice on constructing a dance floor at home. The room my girlfriend and I are planning to use currently has a very un-level concrete floor. I think we'll try some bags of self-leveling concrete compound to take care of that issue...but I need to know what sort of flooring is best to lay down once we have the room leveled off. The dance floor will be mostly used for West Coast Swing. I've seen buzz words like floating floor and sprung floor thrown around elsewhere but nothing very explicit on what they are or how to construct such floors...specifically for swing and ballroom sort of dancing. Any help is appreciated. Thanks.
