Skis and snowboards should be waxed regularly, especially when they have been used in the softer, slushy snow of springtime. Experts from the German Ski Association (DSV) warn that the damp snow pulls the wax out of the pores and the surface becomes less glossy.
To prevent your equipment from losing its all-important gliding properties, you should wax the bottom surfaces at least every second day of skiing. You don't have to go to a specialist ski shop every time - you can also treat them yourself with shop-bought liquid wax.
In spring, while the slopes might still be hard and smooth in the early mornings, as temperatures rise the quality of the snow often deteriorates considerably, particularly in the afternoon.
Sharp edges provide the necessary grip for a safe descent, but at this time of year the hard abrasive surfaces are very wearing, so you will need to sharpen them regularly. As with waxing, this does not always require a visit to the ski service centre. The DSV experts say you can also remove the burr on the edges yourself using sandpaper.
However, a professional ski service is recommended at least once a year, before your skiing holiday. More frequent skiers should also get their equipment professionally serviced during the season, and also when the time comes to store it over the summer and autumn.
