Using infrared heat to wax skis and snowboards 

Remember ROYGBIV, the colors of the rainbow? Well, light is composed of electromagnetic radiation having various wavelengths. The red color has the longest wavelength of the visible spectrum (the distance between the peak of one wave to that of the next). There are other types of electromagnetic radiation that we cannot see.  For example, microwave, which has a relatively long wavelength compared to visible light. This radiation is used for cooking, thus the name microwave ovens. Wavelengths in between the red color and microwaves are called infrared. These wavelengths are usually emitted by heat producing objects such as outdoor heat lamps found at bars and restaurants.

Infrared (IR) technology is used in night vision, heating, cooking, wireless communication such as garage door openers and weather forecasting. Recently, doctors have suggested using IR lamps to help alleviate joint pain, muscle strains, skin rashes and other issues relating to eyes, nose, ears and sinuses. “This heat and other light frequencies improve circulation, hydration, oxygenation and often disable or weaken harmful microorganisms.”¹ IR heat penetrates deeply below the skin making it a highly effective technique.

For some time, ski technicians have been investigating and discussing the use of IR heating to apply wax. In fact, Reichmann (manufacturer of tuning and wax equipment) has introduced the Wall Speed system. It is a compact waxing machine which utilizes infrared heaters to insure a gentile but also intensive treatment. They claim the base is able to absorb more wax, which penetrates deeper and therefore increases service life.²

The GI team has investigated using IR heat instead of an iron using the follow method:

Equipment:

 A standard 250 watt reddish heat lamp by FEIT $10-15 and clamp on lamp socket $10 -$20

Procedure:

Apply the wax to a previously cleaned ski by rubbing the wax on the base making sure the entire ski wax covered. Remove the excess wax with a soft clean cloth.

Turn on the lamp and allow it to heat up. Hold the lamp approximately 2-3 inches above the wax applied base. Allow the wax to melt and flow. As the wax melts move the lamp down the ski until the whole ski surface was treated.

Allow the wax to harden and cool.

Brush with a nylon and horsehair brush.

Observations:

The temperature of the base did not exceed the melt temperature of the wax. In this case 120°F as measured with an Infrared thermometer.

Some advantages noted were that the base temperature could not overheat as the wax flowed evenly and was allowed to penetrate deeply. The temperature was consistent unlike like that of an iron’s temperature which fluctuates during application. Also since the lamp is held over the base, there is no contact and thus no chance to compromise the base material. The technique is fast as scrapping is not required and is safe because the wax does not fume.

 

This technique is not commonly used yet and is still under investigation as to its performance and durability. However, based on the experience of the GI team, it is worth further investigation and has promise as a clear choice for waxing skis and snowboards in the future. Green Ice Wax is an excellent of wax for infrared application as it has a low melting point and excellent flow characteristics.

Rocker Skis and Boards

As early as 2003, rocker skis and boards were introduced to the ski world. However, this technology is nothing new, as water skis and wake boards have taken advantage of the rocker design for many years. Recently, these skis/boards became increasingly popular. Now what is it that makes a rocker design and why is it effective?

1. Camber

First we must look at the traditional shapes available. Since the parabolic shape has become the standard, consider this ski/board as our basis. To describe rocker, a concept of camber must be understood. The traditional ski has a camber. While laying a ski/board riding side down on a flat surface, it can be seen that the center (under the binding) does not touch the underlying surface. Once pushed downward, the flex allows the board to touch. This upward curvature is called camber. It is the camber, in conjunction with the parabolic shape, which allows the rider to carve turns once on edge.

2. Rocker

The newer design for skis/boards is rocker or reverse camber. Now if we do the same thing as with our traditional ski/boards and lay a rocker flat on the surface, the board will touch the underlying surface in the center. The ski/board will flare up at the tip and/or tail. Ski manufactures have produced many variations of rocker skis. The degree of rocker can be from extreme to moderate.

All skis including camber and rocker produce a rocker shape when pressure is applied while turning on edge. A traditional camber board puts more pressure on the tip and tail in the curve as it must flex in order to turn. A rocker ski/board requires less energy to initiate a turn. With the shape of the ski already in a “flexed” position, the ski engages more quickly and effortlessly.

By combining these technologies, manufactures have produced skis and boards that fit all types of terrain and riders abilities.

Reason to Wax: New Skis

New skis need an initial tune up. Certain aspects of the ski need to be checked or modified before skiing. First, check to see if the polyethylene bases are square. A True-bar can aid in checking to see if the bases are concave or convex. Ideally, the bases should be completely flat. If not, you might need to scrape or file to get the bases flat. Next, you will need to tune the edges. Check with the manufacturer to determine the factory angle settings, and then tune to your desired angle if necessary.

Finally, the bases must be tuned (Reason to Wax: Base Construction). Typically, it is not necessary to alter the ski structure, as the manufactures apply structure to the base quite well. However, it is important to scrub the base with Fibertex (resembles a Scotch Brite pad) and stiff brass brush; alternate between rubbing the pad and brush for about 100 passes. Through this process, you will remove the microscopic polyethylene hairs, which could drag on the snow or melt into the ski base when applying hot wax.

Additionally prior to first use, the skis should already contain wax.  If wax already saturates the ski, you do not need to worry should the top layer wear off over the course of daily use. This embedded layer of wax provides extended protection for the base to prevent oxidizing, or turning chalky white, as well as damage from UV Light. This embedded layer also protects against dirt that tends to stick to the base over time.

So now it is time to wax. First, hot-scrape the base in order to clean any fibers and dirt left from brushing. Next, apply a hydrocarbon wax such as Green Ice Ski Wax GIHC warm. Soft waxes are recommended as they penetrate the base more easily (visit How to Hot Wax for an instructional video). Now, some experts prefer to have their skis placed in a hot box for 2-4 hours. Temperature for the hot box ranges from 50-55˚C depending on the wax’s melting point. During the process, the wax slowly and deeply penetrates the pores of the base, allowing it to become saturated with the molten wax. If a hot box is not available or desired, simply repeat the process of applying thin layers of GI HC warm, followed by a cold-scrape and brush. Repeating this process multiple times will better prepare the base for a final wax application of a performance wax such as GI-1000 or GI-2000 available at Green Ice Ski Wax.

Now go hit the slopes, have fun and enjoy your new skis!
