Temperature: Air -10°C to -18°C (14°F to 0°F) PS5 is the hardest wax in the range and is an excellent choice in cold conditions, due to its high durability and its dry friction properties. It's a great choice for both downhill and cross-country skiing. Although it is a wax for cold conditions, the melting point makes it easier to apply than many competitors in this field, without sacrificing excellent gliding properties. For fresh, old or artificial snow. The speed of the iron should be approx. 8 to 10 sec. on a skating ski. The wax can be reheated after cooling to room temperature (10 min) for better durability. Scraping after appr. one minute. Important to have a good iron to get an efficient melting of the wax. Replaces CH5X.PS5 can be used as a racing wax on its own or as a base for topcoats.Recommended iron temperature: 150°C (311°F)
