When referring to a dance floor, the terms "sprung" and "floating" have become nearly synonymous. They both refer to the quality of a dance floor that gives it a little extra spring to absorb the shock of a dancer's foot hitting the floor. In modern floor,s the bounce is provided by rubber feet, or EVA foam squares, spaced out underneath the floor to give it a cushion, rather than the mechanically sprang floors used in the past.
Buy enough cabinet grade ¾-inch plywood panels to fill the area for your dance floor. Cabinet grade plywood is lighter weight and has fewer voids than coarser versions of plywood, making it flex more evenly.
Use construction adhesive to attach 48-inch long, 1-by-2 inch lumber strips to the bottom of each plywood panel running from side to side every 12 inches. Drive 1 ¼ inch drywall screws through the strips into the bottom of the plywood to reinforce the joint about every 18 inches. Construction adhesive, plywood and screws are sold at lumber yards and home centres.
Cut 2-inch squares of ¾ inch EVA foam, available from retail and online upholstery suppliers. Make enough squares to attach one every 12 inches to each 1-by-2 strip on every panel. Attach the foam squares using an air stapler and ¾ -inch narrow crown staples.
Lay out your panels to cover the dance floor area with the foam blocks on the bottom against the floor. Cut down any panels needed to fit along the edges using a circular saw. Leave a ½-inch gap along all walls. Make sure that panels rest snugly side by side. Use gaffer's tape or cloth duct tape along the edges between panels to attach them together.
Cut enough rubberised vinyl flooring to cover your floor panels and lay it out taping the seams between pieces with gaffers tape. Rubberised vinyl dance floor surface typically comes in 4-foot wide rolls. Cut your strips long enough to run the width of the floor. Tape the floor down to the plywood along the edges to keep it from buckling up. Dance floor and gaffer's tape are available from retail and online dance supply stores.
Install a strip of 1-by-2 wood along the edges of the floor where they meet the wall to cover the ½- gap. Do not attach to the wall or caulk the joint. The floor needs to be able to move freely. The 1-by-2 strip can be painted to match the colour of the floor. Paint the strips before installing them to avoid getting paint on the dance surface.
Clean the dance floor by mopping with clear water and a gentle detergent, such as dish soap.
