How To Restore Dwr

Water Repellent Durable (DWR) coating is an essential feature of many outdoor garments and gear, helping to keep you dry by causing water to bead up and roll off the fabric. Over time, however, DWR coatings can wear off due to washing, abrasion, or exposure to the elements, leading to reduced water resistance. Restoring DWR effectively can prolong the life of your gear and maintain its performance in wet conditions. In this comprehensive guide, we will walk you through the steps to restore DWR, the best products to use, and tips to ensure long-lasting water repellency.

Understanding DWR and Its Importance

Durable Water Repellent (DWR) is a coating applied to the outer fabric of outdoor apparel and gear, such as jackets, tents, and backpacks. Its primary function is to cause water to bead up and roll off the surface, preventing the fabric from becoming saturated and maintaining breathability. This feature is crucial for outdoor enthusiasts, hikers, and travelers seeking to stay dry and comfortable during their adventures.

Despite its durability, DWR can degrade over time due to several factors:

• Frequent washing
• Use of harsh detergents
• Exposure to UV rays and environmental elements
• Physical abrasion and dirt buildup

When DWR wears off, fabrics tend to absorb water, leading to increased weight, decreased breathability, and reduced overall performance. Restoring DWR is a simple yet effective way to renew your gear’s water-repelling capabilities.

Signs That Your Gear Needs DWR Restoration

Identifying when to restore DWR is essential for maintaining optimal performance. Look for these common signs:

• Water no longer beads on the surface but soaks into the fabric
• Gear feels heavier when wet
• Water absorption causes discomfort or slows drying time
• Visible areas of wear or dirt buildup that hinder water repellency

If you notice any of these indicators, it’s time to restore or reapply DWR coating to your gear.

Preparing Your Gear for DWR Restoration

Proper preparation ensures the best results when restoring DWR. Follow these steps to prepare your gear:

• Clean thoroughly: Remove dirt, oils, and residues that can interfere with DWR application. Use a specialized technical cleaner or a gentle, non-detergent soap formulated for outdoor gear.
• Check for damage: Inspect your gear for tears, rips, or worn areas. Repair any damage before applying DWR to prevent further deterioration.
• Dry completely: Ensure your gear is fully dry before applying DWR treatment. Most products require a clean, dry surface for optimal adhesion.

Note: Avoid using regular household detergents or fabric softeners, as they can strip or diminish the DWR coating.

Choosing the Right DWR Restoration Product

There are several options available for restoring DWR, including sprays, wash-in treatments, and professional re-coating services. Your choice depends on the type of gear, personal preference, and level of restoration needed.

• Spray-on DWR treatments: Easy to apply and suitable for spot treatment or full coverage. Examples include Nikwax TX.Direct Spray-On, Gear Aid ReviveX, and Grangers Performance Repel.
• Wash-in DWR treatments: Added during laundry, providing a uniform coating. Popular options include Nikwax TX.Direct Wash-In and Grangers Performance Wash.
• Professional re-coating services: For extensive damage or high-performance gear, professional re-coating may be advisable.

Always check compatibility with your gear’s fabric and follow manufacturer instructions for best results.

Step-by-Step Guide to Restoring DWR Using Spray Treatments

Applying a spray-on DWR is straightforward and effective. Follow these steps:

1. Clean your gear: As discussed earlier, thoroughly wash and dry your gear.
2. Prepare a well-ventilated workspace: Apply treatments outdoors or in a well-ventilated area to avoid inhaling fumes.
3. Apply the treatment: Hold the spray bottle about 6-8 inches from the fabric and evenly spray over the entire surface, including seams and hems. Use a light, consistent coat.
4. Allow to dry: Let the treated gear air dry completely, following the product’s recommended drying time.
5. Optional heat activation: Some products recommend a tumble dry or warm iron to activate the DWR coating. Refer to the product instructions for specific details.

By following these steps, you will effectively restore water repellency to your gear.

Restoring DWR with Wash-In Treatments

Wash-in treatments are convenient for treating multiple items simultaneously or re-coating entire garments. Here’s how to do it:

1. Wash your gear: Use a specialized outdoor gear cleaner and rinse thoroughly.
2. Prepare your washing machine: Set to a gentle cycle with cold water.
3. Add the DWR treatment: Follow the product’s instructions to add the recommended amount to the wash cycle.
4. Complete the wash: Run the cycle and then air dry or tumble dry as directed.

Wash-in treatments tend to provide a more uniform application and are particularly effective for waterproof jackets, tents, and other gear that requires full coverage.

Additional Tips for Maintaining DWR Coatings

Restoring DWR is only part of maintaining your gear’s water resistance. Follow these tips to extend the lifespan of your DWR coating:

• Wash gear only when necessary: Frequent washing can accelerate DWR wear. Spot clean when possible.
• Use appropriate cleaners: Always opt for cleaners designed for technical outdoor gear.
• Avoid fabric softeners and bleach: These can strip DWR coatings and damage fabrics.
• Store gear properly: Keep your gear in a cool, dry place away from direct sunlight.
• Reapply DWR regularly: Depending on usage, reapply DWR treatments every 20-30 washes or when water no longer beads.

Conclusion

Restoring DWR is a simple yet crucial maintenance step that can significantly enhance the performance and lifespan of your outdoor gear. By understanding the signs of DWR degradation, preparing your gear properly, selecting the right product, and applying it correctly, you can ensure your gear remains water-resistant and comfortable in wet conditions. Remember that proper care and regular maintenance are key to preserving the effectiveness of DWR coatings over time. With these tips and techniques, you'll be well-equipped to keep your outdoor equipment in top shape and ready for any adventure.
