Ski preparation - Waxing skis
Maintenance of skis and choosing right edge engle
Hello my friends,
Finally we have reached the end of yet another ski season and the end of the ski season . . :)
We are very satisfied with this season, as we have never been before. Weather conditions were good for us skiers and snow-borders, and I hope that we share the same sense of satisfaction.
It is time for us to pack our skis until the next season and this requires a final maintenance.
We have prepared some useful information here for those who are buying new ski equipment this spring.
Prior to leaving the factory, the sliding surface of skis (plastic and edges) is protected by a coating of a thin layer of paraffin. Manufacturers do not imprint this paraffin into the network of channels which extend over the sliding surface. Owners might wax these channels if they want to. It is very important that the sliding surface by waxing is done prior to the first skiing, as otherwise the spaces that were free to receive the wax are significantly reduced. The selected wax must be impressed two to three times at twenty-minute intervals with an iron heated up to around 130 °C. If the impregnation is not done at the same time as the maintenance, it is important to pay attention to the temperature of the iron (if the wax at the iron starts to ‘smoke’, it means the iron is overheated, so the procedure should be discontinued, because we would otherwise impregnate the sliding surface with the remaining wax or rather with this fraction that has a high melting volatility without useful properties. After the skis are cooled down, all the wax from the sliding surface must be removed by a plastic spreader (ruler – a thick piece of plastic) and the remaining wax must be brushed with a nylon brush from fine grooves that make the so-called surface structure. The wax that is forced out in minor quantities under pressure and by friction from the interior while skiing, is quite sufficient to fulfil its function. Impregnation by waxing is necessary for several reasons and primarily due to snow sticking, which makes skiing impossible in some conditions. Skiing on impregnated skis is more comfortable and less tiring. Omission of occasional impregnation, exposure to ultraviolet radiation, the influence of some organic material present at some ski resorts, as well as the effect of oxygen, leads to a process which distorts the structure of sliding surface and it becomes susceptible to abrasion. Spaces for wax storage are also reduced.
At zero service, deformities can be detected, although some may be present at the sliding surface and edges. At zero service, the edges are sharpened at an angle of 88, or 87 degrees for the drivers of S1 category. Edges sharpened this way make skis better in turns, reducing ski sliding, but it is necessary to sharpen them more often than the edges sharpened at 90 degrees.
When the edges become dull, they should only be polished laterally (sideways) and we suggest that the sharpening angle is a 3-degree lateral bevel. The benefits are a better posture on hard surface or ice. In countries of high ski culture, athletes, coaches and the majority of instructors in the days when they work on hard surface check their ski edges daily and run over their lateral sides with a fine grit stone. If necessary they also use a fine holder which ensures the pile is under the angle of 88 or 90 degrees ( 88° or 90° ).
Occasionally, it will also be necessary to adjust the base of the skis and there are two methods for that: Base bevel max 1° and Off-set polishing ( 0,1mm clearance and bevel 1° ).
Always keep in mind that weather conditions on the ground form the snowy surface on the paths and that it can drastically affect the quality of ski base and edges. Wet skis should not be put into the cover as this may cause rusting.
