Consider the type of covering material you use as protection while other trades work on the floor. Be especially aware of radiant heat. Any thick protective covering, such as plywood or Gyproc, will insulate the floor, causing it to overheat. The resulting damage can be difficult and expensive to repair.
Pre-finished floors can be damaged beyond repair in these conditions. Builders paper, laid throughout the hardwood areas, is recommended. DO NOT tape the paper to fresh finish, as you may damage the finish. Overlap the seams and tape the paper to itself. Always cover the floor wall to wall.
