No, but some ski waxes require the use of a waxing iron.
To melt in the hard glide wax and base mount, you need a waxing iron. A good waxing iron will keep the temperature even as you guide it over the ski. Use a good waxing iron for glide waxes and a lower priced variant for base grips. If you use the same waxing iron for both the glide wax and the base grip, make sure that it is cleaned well between each use.
