The present invention concerns an adhesive bonded thermoplastic coating for the underside of a floor that will add significant moisture resistance, wear resistance, transverse crack resistance, and make a better looking, more marketable product. The plastic coated vehicular trailer floor has a plurality of wood planks having a top surface, a bottom surface and a first and second side surfaces, the plank having a width that is less than the lateral width of the floor, each plank being formed by a plurality of boards arranged side-by-side, each board being formed of a plurality of segments joined end-to-end to one another by shaped coupling portions. The planks are arranged side by side such that at least one of the first and second side surfaces faces one of the second or first side surfaces of adjacent planks. Each of the planks has a planar polymer layer formed of an un-reinforced polymer, being bonded to the bottom surface of the planks with an adhesive layer. The adhesive is an epoxy or reactive hot-melt urethane adhesive (but could be any adhesive including urethane, acrylic, hot melt, polyester, vinyl-ester, reactive hot-melt urethane or other equivalent) and the polymer is a PVC thermoplastic sheet (could be any thermoplastic sheet including PET, Polyurethane, Polyurea, Polyethylene, polypropylene, ABS or other equivalent).
