A - Following a few simple rules when stacking and storing a portable gym floor can prolong the appearance and performance of the floor, as well as the finish used to protect the wood. We recommend a minimum of two weeks, three if possible, curing time prior to stacking. Proper stacking is very important! Follow a sequence in which the coated panels are laid face-to-face followed by two panels placed back-to-back, and then two panels laid face-toface. Repeat this sequence so that all finished sides are laid in contact with a finished side of flooring. This requires the persons disassembling the floor to flip panels as they are stacked. As the panels are being stacked, the finished sides are to be separated by brown construction paper or Masonite* panels. Corrugated cardboard may leave a pattern in the finish and certain plastics may stick to the finish due to plasticizer migration.
