To re-waterproof a North Face jacket, you'll primarily want to revive or replenish the Durable Water Repellent (DWR) finish. Here's how:
Reviving the Existing DWR
Often, the DWR finish just needs a little boost. Dirt and oils can reduce its effectiveness.
- Wash the Jacket: Use a technical wash specifically designed for waterproof garments. Follow the manufacturer's instructions on the garment's care label and the wash product.
- Dry the Jacket: This is key! Heat reactivates the DWR. Tumble dry on a low or medium heat setting for the time specified on the care label. If you don't have a dryer, you can iron the jacket on a low setting (no steam), placing a towel between the iron and the jacket.
Replenishing the DWR (If Reviving Doesn't Work)
If the water repellency is still poor after washing and drying, you'll need to apply a new DWR finish.
-
Wash the Jacket (Again): Make sure the jacket is clean before applying a new DWR.
-
Apply a DWR Reproofing Product: You have two main options:
- Wash-In Reproofers: Add the reproofer to your washing machine during the wash cycle. Follow the product's instructions carefully. Nikwax and Grangers are popular brands.
- Spray-On Reproofers: Spray the reproofer evenly onto the clean, damp jacket. Pay attention to high-wear areas like shoulders and cuffs. Allow the jacket to air dry, then tumble dry on low heat to activate the finish (again, following product instructions).
Important Considerations:
- Read the Care Label: Always check the care label on your North Face jacket for specific instructions.
- Use Technical Washes: Avoid regular detergents, fabric softeners, and bleach, as they can damage the waterproof membrane and DWR finish.
- Test the Water Repellency: After reproofing, test the jacket's water repellency by sprinkling water on the surface. The water should bead up and roll off. If it soaks in, you may need to reapply the DWR.
- Ventilation: Ensure the area you are working in is well ventilated, especially when using spray-on reproofers.
By following these steps, you can effectively re-waterproof your North Face jacket and extend its lifespan.
