In fact structures created with stone-grinding machines or manual rillers do not normally touch the snow surface. After the ski base is structured, it is normally cleaned chemically (to remove the cooling and greasing agent residues) and mechanically (to remove the grinding solid residues and unwanted hair) and hot waxed (to create protection film and modify ski base surface for respective snow and weather conditions).
Hot-wax-approach consists of several steps:
1. wax is applied on the clean ski base surface (melted wax can be applied with wax applicator, solid wax can be rubbed on the ski base, wax can be melted on the iron and dropped as liquid on the ski base etc.),
2. wax is ironed with recommended ironing temperature for recommended ironing time (normally from tip to tail with the target to make the wax penetrate to cavities inside amorphous ski base regions where wax molecules can be retained mechanically after ski base and wax cooled down to solid state),
3. ski base with ironed wax layer is allowed to cool down for ca. 20 minutes at mediate temperature,
4. excess wax is removed with scrapers first, from tip to tail, with sharp plastic scrapers carry-fully in flat ski base areas,
5. after excess wax was removed from flat ski base areas, excess wax is removed out of water drainage gutter or gutters with oval plastic scrapers,
6. removing wax out of flat ski base areas with help of scrapers pushed more wax into grooves of structures which are now completely filled with excess wax which was compacted by scrapping,
7. grooves of the structure created with stone-grinding machines or manual rillers need to be restored, i.e. excess wax need to be removed out of the grooves, to remove excess wax out of the grooves brushes are used, normally fine steel or bronze brushes are used to remove excess wax out of the grooves,
8. fine steel or bronze ski brushes have normally hair 25 mm long, with bristles 0,1 mm thin which is bundled to bristle bundles with diameter of ca. 6 mm
9. if the grooves are 0,5 mm wide and ca. 0,05 mm deep (which is a middle fine structure pattern) it is quite obvious, that bristles 0,1 mm thin cannot reach the very bottom of the grooves, or in other words: remove all the excess wax out of the grooves,
10. it can be estimated that the lower 1/3 of the grooves remain filled with wax which is again compacted by the brush bristles
11. wax application makes the originally manufactured structures shallower and more rounded.
Unlike the hot-wax-approach ISANTIN covers the ski base surface with a very thin layer which is ca. 1 to 2 microns thin and thus copying the structure relief almost perfectly, in other words: after ISANTIN application the originally manufactured structure with help of stone-grinding machines or manual rillers remain more or less the same, only covered with an ultra-thin ISANTIN layer.
In fact the good performance of structures is tested and approved for waxed skis, not for plane = unwaxed skis which means the shallower and more rounded structure shapes after wax application are a part of the structure success.
If ISANTIN does not change the structures similarly to waxes, it is needed to change the structures in fabrication process = make them shallower and more rounded in stone-grinding process for ISANTIN.
