What is the best material(polyurethane or other) to use when finishing a dance floor?

Question:

Answers:
Try "Dura-seal"


Steps:

1. Sand floors remove all of the old finish. Use a drum sander for
the major part of the work and an edge sander for the rest.

2. Throughly clean the floor. But, don't use a liquid, it will cause
you to loose a whole day.

3. Apply the first coat of Dura-seal. There will be three. This should
be the thickest coat. Application instructions are provided on the can
you can follow these for the product. I also recommend the Quart size of
Dura-seal. The gallon size is a different formula which takes longer to
dry.

4. Allow 24 hrs for the first coat to dry.

5. With 100 (00) sand paper remove ALL the dura-seal on the SURFACE
of the floor.

6. apply a second and third coat of dura-seal. Allow 8-12 hrs of
dry time between coats.

7. Remove ALL dura-seal from the surface of the floor. If any dura-seal
remains on the surface of the floor it will feel sticky in dance shoes.

You REALLY want to dance right on the wood of the floor.

Once you have completed this process the floor should last about 20-30
years. If you plan ahead you should be able to finish a floor in about
3 days (depending on the size of the floor). I finished 2600 sq ft.
in three days with one helper.
