To wax a snowboard you will need an iron, board wax, a flat scraper and a buffer pad. First, use the iron to melt the wax. The iron should be hot enough to cause the wax to quickly drip but not hot enough to produce smoke. Iron the wax onto the snowboard by using small concentric circles to melt the wax evenly. Go over spots several times, if necessary. Be sure to use wax that is appropriate for your riding conditions. Scrape the excess wax off of the board. Use a buffer pad like the rough side of a sponge to buff the snowboard. Buff in small, tight circles to even out the uneven spots.
