Don Veino mentioned the Montpelier Grange Hall (actually the
"Capital City Grange"). We do have a maple hardwood floor, on a wood-joist
supported subfloor. This has been an excellent dance floor, with good
resilience though not a "sprung" floor. Our Hall is a multi-purpose
facility, used for everything from church services, to meetings, to
birthday & retirement parties. We had to replace the original maple floor
in 2012, after a 60-year lifespan, because it wore down to the
tongue-and-groove joints. After doing some tests, we had the new floor
finished with "Waterlox Original", a modified tung oil varnish. This
finish is largely absorbed into the wood, leaving minimal film on top of
the floor. This has worked pretty well to protect the floor, and provide
the right amount of friction for contra, square and waltz social dancing.
While this works well for these dance events, the wood floor and Waterlox
would certainly not be appropriate if the space is used for basketball or
other athletic events, which require considerably more friction--as anyone
who has contra-danced on a gym floor knows. We did not test the Bona
"Traffic" finish which Don describes.
We did decide to protect the new-in-2012 dance floor with vinyl "gym
floor" mats, which are left in place *except *when dance events happen.
Dance groups roll up the mats onto PVC pipe "cores", which store on a cart
under the stage. For our mix of events, these maps have worked well,
protecting the wood floor from food & drink spills, rain/mud/snow tracked
in from the parking lot, etc. Dancers are well-trained to change shoes
before coming onto the dance floor. We don't have any paid staff to roll
up the mats for an event; dance organizers have to arrange for their groups
to roll up the mats, and then roll them back out after the dance events.
We dust-mop the dance floor, using a light coat of a mop treatment to help
pick up dust from the floor, before dancing and afterward before the mats
are unrolled.
I also agree that we would never recommend dancing on wood flooring
laid over a concrete floor, for the sake of dancers' knees. I do not have
experience with the floor systems that Jim Thaxter links to; I would
certainly recommend visiting facilities with those types of floors and
"test-dancing" on them before planning on using them for
contra/square/waltz/social "folk" dancing.
