we did a dance floor for one night bat mitzah with oracal 631 matte black 30" and a die cut ESPN knock off logo in ij35 + gloss lam. unfortunately no one was injured.
we just used an extra wide 3M power grip CPA-1 felt squeegee and some knee pads.
we've also done a 20x20 floor for a Latin TV show set. high traffic so we used high tack vinyl 3105HT + 10mil polycarb textured laminate. they had a band and three ladies dancing salsa on it at at every commercial break. unfortunately no one was injured either. Although we did have to do a repair. One of the ladies high heels lost the pad on the tip and it was just a metal nail sticking out the bottom of the shoe. but the show must go on. tore up the floor covering in that section and we printed a patch for it.
if its for a permanent install use ASTM rated laminate and a base vinyl with permanent adhesive.
