How to Waterproof a Hat
How to waterproof a hat. Clean and dry it first, then apply a spray-on water repellent made for the fabric, let it cure, and reapply periodically. Speedy Pros Hats, family-owned in Brandon, FL since 2009, makes and decorates hats and can help you keep them protected.
You can make most fabric hats water-resistant with a spray-on repellent, the kind sold for jackets, shoes, and outdoor gear. It will not make a cap fully waterproof, but it helps rain and spills bead up and roll off instead of soaking in. The key steps are cleaning first, matching the spray to the fabric, and reapplying over time.

- Clean and dry first. Spray bonds to a clean surface.
- Use a fabric-matched spray. Water repellent for the material.
- Apply evenly, let it cure. Test a hidden spot first.
- Reapply over time. Repellent wears off with use.
How to Waterproof a Hat
Start clean. A water-repellent spray bonds best to a clean, dry surface, so wash or spot-clean the hat first and let it dry fully, our how to clean a hat guide covers this. Applying repellent over dirt or oils traps them and weakens the coating, so this step matters more than it seems. Pick a spray made for your hat’s fabric: a general fabric or outdoor-gear water repellent for cotton and poly caps, and a suede-and-nubuck protector for a suede hat.
Then apply it evenly. Working outdoors or in a well-ventilated space, hold the can a few inches away and mist the hat in light, even passes so the whole surface is lightly coated, not soaked, then let it cure fully (often a few hours, per the product) before wearing. Test on a hidden spot first to check it does not darken or spot the fabric, especially on light colors. A second light coat after the first cures usually improves the beading.
Then maintain it. Water repellent wears off with use, washing, and time, so reapply periodically, when you notice water no longer beading up. Remember this makes a hat water-resistant, not submarine-proof: it sheds rain and spills far better, but heavy, prolonged soaking will still get through. If you want true weather protection, buying a hat built to be waterproof may suit better than treating a standard cap. To protect color while you are at it, see how to keep a hat from fading.
Waterproofing, Step by Step
Here is the method.
| Step | What to do |
|---|---|
| 1. Clean and dry | Repellent bonds to a clean surface |
| 2. Match the spray | Fabric or suede-specific repellent |
| 3. Test | Check a hidden spot first |
| 4. Apply | Light, even passes, then cure |
| 5. Reapply | When water stops beading |
Clean and dry the hat, match the repellent to the fabric, test a hidden spot, apply in light even passes and let it cure, then reapply as it wears off.
So clean, match, test, apply, and reapply makes a cap shed water, water-resistant, not fully waterproof. For the clean-first step and suede, our how to clean a hat and suede care guides help.
Water-Resistant vs Waterproof
It is worth setting expectations. A spray-on repellent makes a hat water-resistant, rain and spills bead up and roll off, and light showers are no problem, but it does not seal the fabric like a rubber rain hat. In a heavy, prolonged downpour, water will eventually work through, and the coating wears off over time, so it needs reapplying. For everyday rain protection and keeping a favorite cap from soaking, that is usually plenty. If you truly need to stay dry in serious weather, a purpose-built waterproof hat is the better tool.

Waterproofing a Decorated Hat
A light, even repellent coat does not harm an embroidered logo, just avoid soaking any one area.
For a patch, especially leather, use a protector suited to that material and test first.
Applied evenly and cured, the coating is invisible and the logo stays crisp, just as it looked on your proof.
Always test first. Before coating the whole hat, mist a hidden spot and let it dry to be sure the repellent does not darken or spot the fabric, especially on light colors.
Who Waterproofs a Hat

What to Send and What You Get
Send your logo as a vector file when you can — an AI, EPS, or PDF — and we set it up for decoration. A high-resolution PNG works too, and if the art needs cleanup we handle it. Free artwork setup is included on orders of 12 or more, so most orders start with no setup cost at all.
We match your brand colors on the free digital proof, where you see the cap and the logo together before anything is made. Nothing goes into production until you approve that proof, so the first hats off the line is the one you signed off on — colors, size, and placement included.
Reordering is simple. Your setup stays on file, so a repeat run comes back consistent with the first. With no minimums you can start with a single piece or a small batch to confirm the look, then scale up once the design is proven, all from the same shop and the same quick order page.
Every order includes that free proof and our help getting the art right, so you are never guessing at the result. If something is off on our end, we make it right or remake the order on a production error — that is the whole point of proofing before production, to catch anything before a hat is made rather than after.
