Top 5 Mistakes People Make When Reproofing Waterproof Gear (and How to Avoid Them)

Top 5 Mistakes People Make When Reproofing Waterproof Gear (and How to Avoid Them)

When your waterproof gear stops repelling water, it’s time to reproof; however, doing it incorrectly can leave you just as wet as before. Whether it’s your hiking jacket, tent, horse cover, or boots, restoring water repellency isn’t difficult, but it’s easy to get wrong.

1. Using Regular Detergent Before Reproofing

 

Why this ruins waterproofing:

Most people throw their gear in the wash with regular laundry detergent, but supermarket washing powders and detergents leave behind residues that can interfere with durable water repellent (DWR) coatings. These residues attract water and oils, clog the fabric’s pores, and stop water beading on the surface.

What to do instead:

Use a specialised cleaner for waterproof gear. Nikwax cleaners remove particles that inhibit the DWR on your gear, such as dirt, smoke, sunscreen, and body oils, without leaving residue. This wash will restore breathability and prep the fabric for effective reproofing.

 

2. Reproofing Dirty Gear

 

Why it doesn’t work:
Applying waterproofing treatment to a dirty jacket or tent is like painting over a muddy wall. The waterproofing won’t bond properly, and performance will be patchy at best.

Fix it first:
Unless an item or garment is brand new, always clean your gear before applying a DWR treatment. Even if it looks clean, microscopic grime can block the waterproofing from absorbing evenly.

Pro tip: Clean → Then proof. Every time.

 

3. Using the Wrong Waterproofing Product

 

Why this causes damage or failure:
Not all waterproofing sprays or wash-in treatments are suitable for all fabrics. Using the wrong product can clog breathable membranes or leave your gear feeling greasy or stiff.

The right tool for the job

Using the correct product means long-lasting waterproofing that won’t compromise breathability.

 

4. Applying Waterproofing Unevenly or Incorrectly

 

Why this leads to poor results:
Slapping on waterproofing too quickly or in the wrong way can result in patchy coverage, stiff fabric or missed areas that still soak through. 

The correct approach:

Take your time and follow product instructions carefully (whether using a spray-on or wash-in formula).

  • For wash-in treatments like TX.Direct Wash-In, use the correct dosage and spin cycle
  • For spray-on treatments, hang the item up and apply evenly, paying attention to seams, shoulders and high-wear zones
  • Remove any excess with a clean cloth for even coverage

 

5. Expecting Waterproofing to Last Forever

 

Why this leads to disappointment:
Even the best waterproofing treatments wear off over time due to abrasion, exposure to rain, mud, UV rays, and regular use. If you expect one treatment to last for years, you’ll likely find yourself cold, wet and frustrated.

Best practice:
Check your gear regularly. If water stops beading on the surface, it’s time to clean and reproof. With regular maintenance, you’ll get far more life and performance from your gear.

 

Waterproofing Done Right

Don’t let small mistakes undo your efforts. Cleaning and waterproofing your outdoor gear properly keeps you dry, comfortable and protected, whether you’re hiking through the backcountry or just walking the dog in the rain.

By avoiding these common reproofing mistakes and using trusted products like Nikwax Tech Wash and TX.Direct, you can easily revive the waterproof performance of your jackets, trousers, boots and more, without damaging the gear you rely on.
