As part of a full ski tune, waxing your bases is the last step. Many racers wax their skis every time they go out, using special waxes that perform best at different temperatures. Temperature waxes outperform universal waxes, but universal waxes are less labor-intensive--you don't need to wax every time the weather changes. Before waxing, have your bases prepared with a stone grind and P-tex (gouge) repair.
Buy a ski wax iron. While it is possible to wax skis with a basic household iron, it will ruin the iron for any other use and it won't be as effective as a true ski wax iron, which has fine temperature controls. Preheat the iron for about 15 minutes before applying wax to your skis.
Choose Your Wax
Choosing your wax can be difficult. Alpine skiers want a glide wax, as opposed to a grip wax. Universal waxes are designed to work well in all types of snow, but they excel in none. If you are taking the time to get a waxing iron and wax your skis yourself, chances are you won't mind a little extra labor now and again to maintain your skis, so shop for waxes based on temperature. Manufacturers offers waxes for different snow conditions and temperatures. A wax designed for the conditions you are skiing in will significantly improve the ski's performance.
Set Up a Wax Station
Set up a wax station in your home to significantly improve the experience of waxing your skis. The best option is to attach a pair of vise grips to a work bench to hold the skis in place while you wax them. This can also be set up on a table.
Drip the Wax
Hold the wax to the preheated iron and drizzle a thin layer of wax on your bases from tip to tail. Use the iron to apply the wax to your ski bases, going from tip to tail. Let the wax cool.
Scrape Away Wax
Use a plastic scraper to remove excess wax. Hold the scraper at a 45-degree angle to the ski base and work the scraper over the wax from tip to tail. Leave only a fine layer of wax on the ski. Finish the waxing job by using a nylon brush on the base to remove any remaining excess wax. Lastly, use a microfiber cloth to polish the ski base.
