How to Reproof Your Waxed Cotton Raincoat

Depending on how much you wear your trevor nathan raincoat, sooner or later you will need to reproof it. The raincoat’s ability to repel water comes from the wax-infused fabric. The great thing about waxed cotton is you don’t need to buy a new raincoat to regain that “like new” performance. It’s a few easy steps to reproof your waxed cotton raincoat!

To start you will need:
1. A trevor nathan waxed cotton raincoat in need of reproofing
2. A trevor nathan wax bar (if you don’t have one you can buy one here)
3. A blow dryer

Rubbing the wax bar onto your raincoat may seem daunting, but don’t worry! Only certain parts will need reproofing, usually the parts the experience the most wear, or get the most direct rain (such as the shoulders, or the base of the hood). I like to reproof the shoulder seams, since they get direct rainfall.

After you have decided on where to reproof, put the raincoat down in one layer on a flat, smooth surface. Use one hand to hold the wax bar, and the other to keep the fabric slightly stretched.

In a long pulling motion, rub the wax bar along the area you wish to reproof. Use a pulling motion only, do not push the wax bar forward. Rubbing too hard back and forth can damage the fabric. Also, when reproofing seams, do not try to pull the seams open to apply the wax. The wax will infuse when it is heated with the blow dryer.

You shouldn’t need to use too much pressure to apply the wax to the fabric. Apply to all the areas you need before moving on to the blow dryer. After you rub on the wax, the fabric will look look whiter, and feel slightly rough and sticky, like in photo 2.

The next step is to use the blow dryer to melt the wax and infuse it into the fabric. This will create a “like new” look. Before using the blow dryer, pull the outer wax shell away from the lining. Heating the waxed cotton directly on top of the lining will cause the wax to bleed onto the lining. Be especially careful if you have a light-colored lining.

Holding the waxed cotton up and away from the lining, use the blow dryer to melt the wax onto the fabric. You will probably need the “high” setting to properly melt the wax. Hold the blow dryer about a foot away to start, and blow over the whole area. Get closer as needed. You will see the wax melt and soak into the fabric. It will look like photo 4.

Once the wax is completely melted, turn off the blow dryer, but continue to hold the fabric up until it cools down. Let the wax get to room temperature and harder before letting it touch the lining (about a minute).

Once cool, your raincoat is ready to go! If you want, you can test it out by running some water on it. You can add more wax, or blow dry it again if it didn’t fully absorb. The reproofed raincoat will look like photo 5.

Enjoy the rain!
