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