At Home Owners Association, we understand the importance of keeping your outdoor gear in top condition.

Waterproofing your jacket is a simple yet effective way to extend its life and maintain its performance.

In this guide, we’ll walk you through the process of using waterproofing spray for jackets, ensuring you stay dry and comfortable during your outdoor adventures.

Which Waterproofing Spray Is Best for Your Jacket?

Selecting the right waterproofing spray for your jacket is essential for maintaining its water-repellent properties. Let’s explore the options and factors to consider when making your choice.

Types of Waterproofing Sprays

Waterproofing sprays fall into two main categories: silicone-based and fluoropolymer-based. Silicone sprays offer an affordable option and work well on natural fabrics like cotton and leather. Silicone coatings actually increase the tear strength of the fabric to which they are applied. Fluoropolymer sprays, while more expensive, provide superior performance on synthetic materials and breathable fabrics (such as Gore-Tex).

Factors to Consider

When selecting a spray, you should take into account your jacket’s material, intended use, and environmental impact. For a high-performance hiking jacket, choose a fluoropolymer spray that won’t compromise breathability. For everyday wear, a silicone-based product might suffice.

Environmental consciousness plays an increasingly important role in product selection. Many brands now offer PFC-free formulations that reduce harm to the environment. PFCs are mainly used for waterproofing jackets, walking boots and tents.

Top Brands and Recommendations

For synthetic fabrics, Nikwax TX.Direct Spray-On receives high marks from users. It’s PFC-free and easy to apply. Grangers Performance Repel Plus is another excellent choice, especially for technical outerwear.

If you need to treat leather or suede, consider Scotchgard Suede & Nubuck Protector. This product is specifically formulated for these materials and provides long-lasting protection.

For those seeking an all-rounder, Kiwi Camp Dry Heavy Duty Water Repellent performs well on various fabrics and offers a budget-friendly option.

Application Tips

The effectiveness of any spray depends on proper application. Always follow the manufacturer’s instructions carefully. Users who take the time to apply the product correctly see significantly better results.

As you prepare to waterproof your jacket, the next step involves getting your garment ready for the treatment process. Let’s move on to the essential steps you need to take before applying your chosen waterproofing spray.

How to Prep Your Jacket for Waterproofing

Clean Your Jacket Thoroughly

Start with a deep clean of your jacket. Use a specialised cleaner for outdoor gear like Sportsuds or Nikwax soap to avoid residues that might interfere with waterproofing. Focus on areas that collect dirt, such as cuffs and collars. For stubborn stains, use a soft brush to gently scrub. Rinse the jacket thoroughly to remove all soap residues.

Ensure Complete Drying

After washing, dry your jacket completely. Hang it in a well-ventilated area away from direct sunlight or heat sources. Don’t use a dryer unless the care label specifically allows it. Moisture trapped in the fabric can prevent the waterproofing spray from bonding properly. To speed up the process, you can use a fan, but patience is key. Drying can take anywhere from a few hours to a full day (depending on the material).

Protect Sensitive Areas

Identify areas of your jacket that shouldn’t come into contact with the waterproofing solution. These typically include zips, elastic cuffs, and any parts with a different material or finish. Use masking tape to cover these areas carefully. This step protects these parts from potential damage and ensures the spray is applied only where needed, maximising its effectiveness.

Inspect for Damage

Before applying any waterproofing treatment, inspect your jacket for tears, loose seams, or other damage. Repair any issues you find, as waterproofing won’t be effective on damaged areas. Small tears can often be fixed with a patch kit designed for outdoor gear.

Create an Ideal Application Environment

Choose a well-ventilated area for the application process. If possible, work outdoors or in a garage with open doors. The area should be clean and free from dust or debris that could stick to the wet spray. Try to maintain a consistent temperature (around 70°F or 21°C) during application, as extreme temperatures can affect how the spray adheres to the fabric.

Now that your jacket is prepped and ready, it’s time to move on to the actual application of the waterproofing spray. The next section will guide you through this process step-by-step, ensuring you achieve the best possible results.

How to Apply Waterproofing Spray Effectively

Set Up Your Workspace

Choose an area with good ventilation for your application process. Work outdoors or in a well-ventilated garage if possible. If you must work indoors, open all windows and use fans to circulate air. Maintain a temperature of about 21°C (70°F) for optimal results. Protect surfaces from overspray by laying down a drop cloth or old newspapers.

Master the Spraying Technique

Hold the spray can 15-20 cm (6-8 inches) away from the jacket. Spray in a steady, sweeping motion, moving horizontally across the fabric. Overlap each pass slightly to ensure full coverage. Focus extra attention on high-wear areas like shoulders, elbows, and cuffs, as these spots often require more product.

To achieve even distribution, spray in a crisscross pattern. After your horizontal passes, cover the jacket again with vertical strokes. This method helps the product penetrate the fabric more effectively.

Apply the Right Number of Coats

Most jackets need two coats for optimal waterproofing. Wait 10-15 minutes after applying the first coat for it to dry to the touch. Then, apply a second coat using the same technique. Some heavy-duty outdoor jackets might benefit from a third coat, especially in areas prone to high water exposure.

Between coats, gently pat down any areas where the spray might have pooled. This action prevents uneven application and ensures the product bonds properly with the fabric.

Allow Proper Drying Time

After the final coat, let the jacket dry completely before use. This process typically takes 24 to 72 hours as specified by most manufacturers. Avoid wearing or compressing the jacket during this time to allow the waterproofing treatment to set properly.

Test the Waterproofing

Once the jacket is completely dry, test its water repellency. Sprinkle some water on the surface and observe how it beads up and rolls off. If water soaks into the fabric, you might need to apply an additional coat of waterproofing spray.

Final Thoughts

Waterproofing spray for jackets offers a simple yet effective way to protect your outdoor gear. The process involves selecting the right product, preparing your jacket, and applying the spray with care. You will extend the life of your gear and enhance its performance in wet conditions through these steps.

Regular maintenance of your newly waterproofed jacket will ensure its longevity. Wash it sparingly with a gentle detergent designed for technical fabrics. Reapply the waterproofing treatment as needed, typically every few months or after heavy use in wet conditions (depending on the product instructions).
