I use Iron Maiden iron dedicated iron for ski. In past I used paraffin from Safeway and a second hand household iron, iron was ok. Now I much prefer Yellow from +5 to -5 n Red from -5 to -15, IT DOES make a diff as temp change , believe it. Also I wax every session n sometime 2 time if over 3 hours, it take less then 5min . after 2.5 hours board doesn't glide the same n I Feel the resistance.
1. put board flat or 45degre as I prefer , I wax one side top down n reverse board. for ski flat on garbage can , use coat hanger to pull back binding.
2 . iron very hot ( around 135degre I guess) , put wax against iron n let fall on ski like 1/4 of the way sparingly.(first time you need way more wax then subsequently as board keep some. don't wait theres none left, it takes longer to redo n way more wax.)
3. apply iron against board n always keep moving circular motion back n forth, do not stop moving to keep from melting deck, don't worry, it can take a lot of heat, but keep moving not too fast or slow. you will visually see where wax is needed. wt board at 45, I skim it down at same time.also add wax if spot needed.
4. as wax is dry(look flat mat),don't wait, use a metal or plastic scraper at close to 90 n scape toward you to remove bumps n do all the deck.i use metal, plastic safer I guess.
5 . finish wt lightly buffing deck wt back of sponge green or blue scrubber to solidify the wax. . Good job. takes less then 5min.
I recommend Briko yellow and red wax from MEC. A step better would be wax wt Fluro, but that is very Super expensive. check a couple U tubes videos .wax when I park car after session. if I change wax color, I just apply over the old one. unless it was waxed n Not ridden, then use paper towel n apply iron against paper against the board to absorb old wax. at Cypress you will use more Yellow then red.
