To re-waterproof your waterproof jacket, you need to clean it, prepare it, apply a durable water repellent (DWR) treatment, and then dry it properly. Here's a step-by-step guide:
Steps to Re-Waterproof Your Jacket
-
Clean Your Jacket:
- It's essential to start with a clean jacket. Dirt and oils can prevent the DWR treatment from bonding correctly.
- Use a specialized technical wash designed for waterproof clothing, such as Nikwax Tech Wash or Grangers Performance Wash. Regular detergents can damage the waterproof membrane.
- Follow the garment's care label and the wash product's instructions carefully.
- Close all zippers and Velcro closures before washing.
-
Prepare Your Jacket:
- Ensure all pockets are empty.
- Zip up all zippers and close any flaps or closures.
- Loosen any drawcords. This helps the spray reach all areas.
-
Apply a DWR Treatment:
- Wash-In Treatment: You can use a wash-in DWR treatment like Nikwax TX.Direct or Grangers Performance Repel. Follow the instructions on the product label, typically involving washing the clean jacket with the DWR treatment.
- Spray-On Treatment: Alternatively, you can use a spray-on DWR treatment like Nikwax TX.Direct Spray-On or Grangers Performance Repel Plus.
- Hang the clean, damp jacket on a hanger.
- Spray the DWR treatment evenly over the entire outer surface of the jacket, holding the nozzle about 6-8 inches away.
- Pay attention to high-wear areas like shoulders, cuffs, and around zippers.
- Wipe away any excess DWR treatment with a clean cloth to prevent streaks.
-
Dry Your Jacket:
- Drip Dry: Let the jacket drip dry in a well-ventilated area until it's no longer dripping.
- Tumble Dry (If Allowed): Check the garment's care label. Many waterproof jackets benefit from tumble drying on a low or medium heat setting, as the heat helps to activate the DWR treatment. If tumble drying, do so for about 20-30 minutes. Avoid over-drying.
Important Considerations:
- Care Label: Always check the manufacturer's care label on your jacket for specific washing and drying instructions.
- Membrane Type: Be aware of the type of waterproof membrane your jacket has (e.g., Gore-Tex, eVent, proprietary membranes). Choose a DWR treatment compatible with that membrane.
- Regular Maintenance: Re-waterproof your jacket regularly, especially after heavy use or washing, to maintain its performance. The frequency depends on how often you use the jacket and how exposed it is to the elements.
By following these steps, you can effectively restore the waterproofness of your jacket and keep it performing at its best.
