How to Finish a Dance Floor


The last step to installing a dance floor is applying the finish, which can be a very labor-intensive process. Done correctly, your floor should last anywhere from 20 to 30 years, but if your floor is done incorrectly, you'll have to start the three-day process of finishing it all over again. The floor should look good, but it should also be functional. It's recommended that you don't use finishes with polyurethane, which will not hold up to the stress of rigorous dancing conditions.

Things You'll Need

  • Hard wood finish
  • 100-grit sandpaper
  • Knee pads (optional)
  • Prep the floor by sanding and thoroughly cleaning it without using any liquid.

  • Apply the first coat of sealant to the floor in accordance with the directions on your product. This coat should be the thickest, as it will be the first of three.

  • Allow the first coat 24 hours of drying time.

  • Sand the floor with 100-grit sandpaper to remove any extra sealant from the surface of the floor.

  • Apply the second coat of sealant. Allow 8 to 12 hours of drying time.

  • Sand the floor again, removing any thick layers of sealant.

  • Apply the third and final layer of sealant, and allow 12 hours of drying time.

  • Sand the entire floor for the last time, checking with your bare hand for rough patches and thick sealant spots.

Tips & Warnings

  • If you don't sand properly between coats, the wood floor will feel sticky to the dancer.
