On most gym floors and other wood floors where existing finish has not worn through, excellent results are secured by simply cleaning and re-coating with Gym Finish #40U. Machine-scrub the floor with water and a good detergent using a nylon stripping pad. Lustreen detergent or similar product is recommended. Rinse thoroughly and let dry. Apply Gym Finish #40U with a wool applier. One coat is normally enough.
If worn through to bare wood or last top-coat was moisture-cure urethane, discing or sanding is probably needed. Call for specific recommendations.
