Waterproof Shells: Best Treatments & How to Restore

Technical outerwear, particularly shells made from materials like Gore-Tex, eVent, and other waterproof-breathable membranes, is a significant investment. These jackets and pants are designed to keep you dry and comfortable in challenging conditions, but their performance degrades over time. Dirt, body oils, and repeated use can clog the pores of the fabric, reducing its ability to breathe and repel water. Fortunately, regular care and the right waterproofing treatments can restore and maintain their protective qualities.

This article will explore the best waterproofing treatments available, how to determine if your shell needs treatment, and a step-by-step guide to restoring its water repellency. We’ll cover different types of treatments, application methods, and preventative measures to extend the life of your valuable gear.

Understanding Waterproofing and Breathability

Before diving into treatments, it’s crucial to understand how waterproof shells work. Most rely on two key properties: a waterproof membrane and a Durable Water Repellent (DWR) finish. The membrane prevents water from entering, while the DWR coating causes water to bead up and roll off the surface, preventing the fabric from becoming saturated. When water saturates the outer fabric, it reduces breathability, as the membrane struggles to move moisture vapor away from your body.

DWR isn’t permanent. It wears off with use and washing. When water stops beading and starts to soak into the fabric, it’s a clear sign that the DWR needs to be refreshed. Ignoring this can lead to a ‘wet-out’ effect, where the outer fabric becomes saturated, compromising both waterproofing and breathability. You might find yourself feeling damp even without rain, as the jacket struggles to manage internal moisture.

Types of Waterproofing Treatments

Several types of waterproofing treatments are available, each with its pros and cons:

• Spray-on DWR: These are easy to apply and generally affordable. They’re suitable for spot treatments or refreshing the entire garment. However, they may not provide as durable a finish as wash-in treatments.
• Wash-in DWR: Added to the washing machine during the rinse cycle, these treatments offer more even coverage and tend to last longer. They’re a good option for a thorough restoration.
• Nikwax Tech Wash & TX.Direct: Nikwax is a popular brand specializing in outdoor gear care. Tech Wash cleans the garment, preparing it for the TX.Direct waterproofing treatment, which restores DWR.
• Grangers Performance Wash & Repel: Similar to Nikwax, Grangers offers a two-step system for cleaning and re-waterproofing.
• Revivex: Another well-regarded brand, Revivex offers both wash-in and spray-on options.

How to Tell if Your Shell Needs Treatment

The “water bead test” is the simplest way to assess your shell’s water repellency. Sprinkle a small amount of water onto the surface of the fabric. If the water beads up and rolls off, the DWR is still functioning effectively. If the water soaks in, leaving a dark patch, it’s time for a treatment. Pay attention to areas that experience the most wear, such as the shoulders, hood, and cuffs.

Another indicator is a noticeable decrease in breathability. If you find yourself feeling clammy or damp during activity, even in cool conditions, the fabric may be saturated, hindering its ability to vent moisture. Consider checking your clothing care labels for specific recommendations from the manufacturer.

Step-by-Step Guide to Waterproofing Your Shell

1. Clean the Garment: Use a technical wash specifically designed for waterproof fabrics (like Nikwax Tech Wash or Grangers Performance Wash). Regular detergents can leave residues that reduce performance.
2. Rinse Thoroughly: Ensure all traces of detergent are removed.
3. Apply Waterproofing Treatment: Follow the instructions on the product label. For spray-on treatments, apply evenly to a clean, dry garment. For wash-in treatments, add the product to the rinse cycle.
4. Dry the Garment: Heat can help activate the DWR finish. Tumble dry on low heat (check the garment’s care label first) or iron on a low setting with a towel between the iron and the fabric.
5. Re-test: Once dry, repeat the water bead test to confirm the treatment was successful.

Preventative Measures to Extend Waterproofing

Beyond regular treatments, several preventative measures can help prolong the life of your waterproof shell:

• Wash Sparingly: Only wash your shell when necessary. Frequent washing accelerates the breakdown of the DWR finish.
• Use Technical Detergents: Always use detergents specifically designed for waterproof fabrics.
• Avoid Fabric Softeners and Dryer Sheets: These leave residues that can clog the fabric’s pores.
• Store Properly: Store your shell in a cool, dry place, away from direct sunlight.
• Avoid Abrasive Surfaces: Be mindful of surfaces that could wear down the DWR finish, such as rough rocks or backpacks.

Choosing the Right Treatment for Your Shell

The best treatment depends on the fabric of your shell and your personal preferences. For Gore-Tex garments, Nikwax and Grangers are often recommended. Always check the garment’s care label for specific instructions. If you’re unsure, test the treatment on a small, inconspicuous area first. Understanding the material composition of your shell can help you make an informed decision. For example, some treatments are better suited for nylon shells, while others work best on polyester.

Conclusion

Maintaining the waterproof performance of your technical shell is essential for staying dry and comfortable in the outdoors. By understanding how waterproofing works, recognizing the signs of wear, and applying the appropriate treatments, you can extend the life of your investment and enjoy years of reliable protection. Regular cleaning and preventative care are also crucial for maximizing the effectiveness of waterproofing treatments. Don't let a worn-out DWR ruin your next adventure – a little maintenance can go a long way.

Frequently Asked Questions

• Question: How often should I re-waterproof my jacket?
• Answer: It depends on how often you use it and the conditions you expose it to. As a general guideline, re-waterproof your jacket every few months of regular use, or whenever you notice water is no longer beading up on the surface.
• Question: Can I use a regular detergent to wash my waterproof jacket?
• Answer: No, regular detergents contain chemicals that can damage the waterproof membrane and DWR finish. Always use a technical wash specifically designed for waterproof fabrics.
• Question: Will waterproofing treatments affect the breathability of my jacket?
• Answer: When applied correctly, waterproofing treatments should not significantly affect breathability. In fact, restoring the DWR finish can actually *improve* breathability by preventing the outer fabric from becoming saturated.
• Question: What’s the difference between a spray-on and wash-in DWR treatment?
• Answer: Spray-on treatments are easier to apply for spot treatments, while wash-in treatments provide more even coverage and generally last longer. Wash-in treatments are ideal for a full restoration.
• Question: Can I repair a damaged waterproof membrane?
• Answer: Minor tears or punctures in the membrane can sometimes be repaired with specialized patches designed for waterproof fabrics. However, significant damage may require professional repair or replacement of the garment.
