Use a level to determine whether the area where you want your dance floor is perfectly even. If building a dance floor outdoors, rake or shovel the ground until it is level.
Arrange the particleboard sheets over the flat surface or ground and mark with a pencil if they need to be trimmed. Saw to trim.
Determine where to put the strips of particleboard underneath the sheets by marking where each sheet meets on the ground or surface below, using a pencil to draw a line. Remove the particle board sheets and place the strips down on each joint, according to your marks. Place strips around the entire perimeter of the dance floor.
Stack the particle board sheets over the joining strips and drill small holes through both the sheets and strips every 3 inches on both sides of the joints and all the way to the corners of the sheets.
Screw in the 1-inch screws into all of the pre-drilled holes.
Optional: Measure and cut metal or plastic dance floor edging to edge your new dance floor if desired. Screw in place. Finish the floor with wood stain and polish for a smooth and attractive surface.
