Waterproof jackets are an essential part of outdoor wear and help to protect you from the weather. Over time, their ability to be waterproof can deteriorate, but there are ways you can reproof your jacket so that you can safely wear it out in the rain again.
Recognising when your jacket needs reproofing
Waterproof coats should be reproofed every three to four months if you frequently wear the coat or every six to twelve months if you wear it less often The most obvious sign that your jacket needs to be reproofed is when it starts to absorb water rather than repel it. This is caused by wear, washing, and exposure to dirt and oils that can affect the waterproof coating.
Preparation for reproofing
Before reproofing, clean your jacket using a specialist technical clothing detergent. Regular household washing liquids or tablets can damage the fabric and block the breathable membrane. Always check the care label first, and always wash your jacket according to the manufacturer’s instructions.
Waterproofing spray method
Using a waterproofing spray is a straightforward way to restore the water-repellent properties of a jacket. First, make sure the jacket is clean and completely dry; next, hang the jacket on a washing line or place it on a flat surface in a well-ventilated area. Spray the coat from a distance of around 15 to 20 centimetres. You may need to add an extra coat on the elbows and shoulders, as they are high-wear areas. After spraying, let the jacket dry naturally.
Wash-in waterproofing treatment
Another method is a wash-in waterproof treatment, which works by adding a liquid to the washing machine. Run the wash cycle at 30ºC or according to the care instructions on the jacket. If you need luxury water resistant fabrics, businesses such as Extex have a wide range.
Important considerations
Always test the product on a small area first to make sure it doesn’t affect the appearance of the fabric. Different materials may need specific reproofing methods, so always check the label first.
