Yes a polyurethane finished hardwood floor may have additional coats of polyurethane applied. Difficult to repair if pre finished hardwood flooring gets scratched or dented during installation you have no option but to replace the entire floorboard.

Can prefinished hardwood be sealed to avoid this problem. There is no way you can ever manually duplicate the factory coating.
