Graphite waxes are intended for graphite soles. All black ski soles are graphited. After several uses, these soles lose their graphite load and therefore the hydrophobic capacity is reduced. Waxing with a graphite wax will then recharge the base. These waxes (bases) should be used every 7 to 10 waxings to recharge the base. Graphite bases are used regularly because of the lubricating power of graphite on specific snow.
