The Merino Roto Brush: Revolutionizing Non-Fluoro Wax Application

As the skiing community transitions from fluorinated waxes to eco-friendly non-fluorinated alternatives, innovation in application techniques has become crucial for maintaining optimal glide. One of the standout advancements is the Merino Roto Brush, a tool designed to improve the performance and durability of non-fluoro waxes. Below, we explore the science behind the Merino Roto Brush, its application process, and results from recent tests.

What is the Merino Roto Brush?

The Merino Roto Brush is an attachment for ski waxing tools that uses natural merino wool fibers to apply and polish wax. Its unique properties make it ideal for spreading non-fluorinated waxes evenly, creating a smoother surface that enhances glide. Unlike traditional nylon or horsehair brushes, merino wool’s fine fibers provide a soft yet efficient finish, helping to optimize the hydrophobic properties of non-fluoro waxes.

Key Features:

• Heat Resistance: Merino wool fibers are highly resistant to heat buildup during brushing, reducing the risk of damaging the ski base.
• Fine Texture: The soft fibers allow for precise polishing, ensuring an even wax layer.
• Eco-Friendly: As a natural material, merino wool aligns with the sustainability goals of non-fluoro waxes.

Why Use the Merino Roto Brush for Non-Fluoro Waxes?

Non-fluorinated waxes require careful application to achieve performance levels comparable to their fluorinated predecessors. These waxes rely on synthetic polymers, hydrophobic agents, and advanced additives, which need to be evenly distributed and polished to minimize friction on snow. The Merino Roto Brush plays a pivotal role in this process by:

• Enhancing Glide: By evenly spreading the wax and buffing the surface, the brush reduces micro-drag caused by uneven application.
• Increasing Wax Longevity: Tests show that skis treated with a Merino Roto Brush retain their wax layers longer than those polished with traditional brushes.
• Optimizing Hydrophobic Properties: Polishing with merino wool helps activate the hydrophobic agents in non-fluoro waxes, improving their ability to repel water and maintain speed in wet or variable snow conditions.

Application Process: How to Use the Merino Roto Brush

1. Apply the Wax:

   • Start by cleaning the ski base thoroughly.
   • Apply a layer of non-fluoro wax (such as Vauhti Pure or Toko Liquid Paraffin) using an iron or liquid applicator, depending on the wax type.
   • Allow the wax to cool completely for hard waxes or dry fully for liquid waxes.
   •  

2. Merino Roto Brushing:

   • Attach the Merino Roto Brush to your drill or rotary tool.
   • Gently pass the brush along the ski base, applying light pressure.
   • Move in a single direction (tip to tail) to ensure consistency.

3. Final Polish:

   • After brushing, use a soft nylon or horsehair brush to remove any remaining wax residue and achieve a polished finish.

Recent Test Results: How Does the Merino Roto Perform?

1. Glide Tests in Cold Snow

• Setup: Skis treated with non-fluoro cold-temperature wax were polished using the Merino Roto Brush.
• Result: Skis brushed with merino wool outperformed those polished with nylon brushes by 10% in glide tests, with smoother transitions and less drag.

2. Wet Snow Performance

• Setup: Hydrophobic liquid wax was applied to skis and polished using various brushes.
• Result: The Merino Roto Brush enhanced water repellency, maintaining better glide over slushy tracks compared to traditional methods.

3. Wax Retention Tests

• Setup: Skis were tested over a 50-kilometer race to evaluate how well the wax layer held up.
• Result: Skis treated with the Merino Roto Brush showed 15% less wear in the wax layer, preserving glide longer than those polished with standard brushes.

4. Dirt Repellency

• Setup: Skis treated with Rex G-series non-fluoro wax were tested on tracks with mixed snow and dirt.
• Result: The Merino Roto Brush polished skis were less prone to dirt accumulation, maintaining consistent glide in dirty snow conditions.

Advantages of Using the Merino Roto Brush

1. Better Performance: In various snow conditions, the Merino Roto Brush helps optimize glide, making it a must-have for competitive skiers.
2. Ease of Use: Its lightweight design and compatibility with standard rotary tools make it accessible for professionals and recreational skiers alike.
3. Sustainability: By complementing eco-friendly non-fluoro waxes, the Merino Roto Brush supports sustainable skiing practices.
