How can I make a jacket waterproof?

There are several solutions available to make a jacket waterproof. HG offers products suitable for both 100% synthetic textiles and cotton, linen, wool and mixed fabric blends. These make the jacket water and dirt repellent and can be used by hand wash or in the washing machine. In addition, there are household remedies such as a mixture of water and vinegar, beeswax, petroleum jelly or natural water-repellent sprays. Do note that these may affect the lifespan or quality of the jacket. Regular maintenance, such as treating with water-repellent sprays and correct washing, helps maintain waterproofing.

HG solutions for waterproofing jackets

If you want to make your raincoat or other clothing waterproof again, HG products offer the answer. Depending on the material your jacket is made from, there are different options:

• For jackets made from 100% synthetic textiles, such as polyamide, polyester and nylon, HG waterproof for clothes and fabrics is the best choice. This product makes your ski and rain clothing, as well as garden furniture covers, water and dirt repellent.
• For jackets made from cotton, linen, wool and mixed fabric blends, we recommend HG waterproof for clothes and fabrics. This product is suitable for children's clothing, rainwear, denim and more.

Both products can be used either by hand wash method or in the washing machine. For the best results, it is important that the clothing is clean and dry before you start. After treatment, it is best to iron the clothing before it is completely dry to enhance the effect of the HG products, if the care label allows ironing.

Solutions for waterproofing jackets

There are various household solutions you can try to make your jacket water-resistant or restore its water repellency after washing. While these solutions are not always as effective as professional products and sometimes carry risks, they may be worth trying if you do not have access to purpose-designed products:

• Use a mixture of equal parts water and vinegar, and spray it onto the jacket. Allow the jacket to air dry.
• Apply a layer of beeswax to the fabric. Gently heat the wax with a hairdryer so it spreads evenly across the jacket.
• Rub a very thin layer of petroleum jelly into the jacket. Work it carefully across the surface, but be aware that it may leave a greasy finish or affect breathability.
• Use a water-repellent spray made from natural ingredients, if suitable for your jacket fabric.

Bear in mind that these methods may affect the lifespan, breathability or quality of your jacket. Always test first on a small, inconspicuous area before treating the whole jacket.

Causes of a jacket losing its waterproofing

A jacket can lose its waterproofing for various reasons:

• Fabric wear: Through regular use and friction, the water-repellent layer on the fabric can wear away, allowing water to penetrate more easily.
• Dirt and greasiness: Build-up of dirt, oil and other greasy substances on the fabric can reduce water-repellent properties.
• Incorrect washing: Washing a jacket at too high a temperature or with the wrong detergent can damage the water-repellent layer.
• Damage: Tears, holes or other damage to the fabric can allow water to penetrate, even if the water-repellent layer is still intact.

To prevent your jacket from losing its waterproofing, you can take the following steps:

• Treat the jacket regularly with a water-repellent product, especially after washing.
• Wash the jacket according to the instructions on the label and use a specialist detergent for outdoor clothing if required.
• Avoid excessive wear by using the jacket carefully and storing it properly.
• Repair any damage promptly to prevent it from getting worse and affecting waterproofing further.
