How to Apply a Vinyl Decal: A Beginner’s Guide
Vinyl decals are a simple way to jazz up an otherwise plain-looking hat. They're a bit like stickers, but more durable, made from a non-removable vinyl material that can be applied to pretty much any item of clothing or accessory, from hats and bags to t-shirts and jackets.
If you've never applied a vinyl decal to fabric before, you need to know the basics so you can get it right the first time. Applying vinyl decals isn't something you get to do over if you make a mistake! In this step-by-step guide, we're walking you through the process of applying a vinyl decal to a hat or fabric.

What You Need Before Applying a Vinyl Decal
Before you get started, you'll need to get your hands on the right tools, including:
-
The vinyl decal itself
-
Transfer tape or backing paper (if it’s not already attached)
-
A squeegee or credit card
-
Rubbing alcohol
-
A lint-free cloth
-
Either a heat press or an iron
You'll also need to do a bit of prep before you apply the vinyl sticker, including cleaning the surface thoroughly. If you're applying the decal to a hat that's already been worn, it's a good idea to wipe the area with rubbing alcohol to remove any sweat or residue.
Applying vinyl decals to cotton or polyester fabric? Wash and dry the material without fabric softener first, so the decal sticks better.
How to Apply a Vinyl Decal to a Hat or Fabric
Follow this easy step-by-step process for a successful vinyl decal application on a hat or fabric:
-
Start by positioning the decal exactly where you want it. You could always mark the material with a fabric pen if you want to be really precise.
-
Slowly peel the backing off, keeping the vinyl on the transfer tape.
-
Press the decal down onto the hat or fabric with firm pressure.
-
Smooth the decal from the center outward and use your fingers or a squeegee to push out any air bubbles.
If you're using a heat press or iron, follow these instructions instead:
-
Set the heat press to around 305°F (if you're using an iron, set it to the cotton setting with no steam).
-
Cover the decal with a bit of parchment paper or a Teflon sheet to protect it.
-
Press the decal for 10 to 15 seconds.
-
If your iron doesn’t cover the entire decal in one go, lift it up, relocate, and press again.
Once the decal has cooled slightly, peel off the transfer paper, starting at a corner and pulling back slowly at a sharp angle. If any part of the decal lifts, that means it needs to be pressed again for a few more seconds.
If you're looking to apply a vinyl decal on hats specifically, you'll need to apply firm, curved pressure and pay more attention to keeping everything flat and even.

Common Mistakes to Avoid When Applying Decals
Make sure you avoid making the following mistakes when you're applying vinyl stickers to your hats or clothes:
Rushing the Prep
It's totally understandable if you want to get your sticker in place as soon as possible, but don't let this be at the expense of getting the transfer just right. If you don't prep the surface properly in advance, your decal might end up with weak spots (meaning it's more likely to peel, especially after a few wears and washes).
Not Using Enough Pressure
Another mistake that's easy to make is not using enough pressure when you're applying the decal. You need to press it in firmly, especially at the edges, so it'll bond properly. Again, failing to do this will likely cause the sticker to peel away from the material. On a similar note, don't move the iron while you're pressing, as this can cause the decal to move slightly and wrinkle.
Using Steam or Too Much Heat
Heat is often necessary when you're applying adhesive vinyl decals, but too much can warp or melt your stickers, which obviously isn't the effect you want. It's best to check the temperature guide for your specific vinyl type so you know you're getting it right. As for steam, you should never use this, since it adds moisture that can break the adhesive bond.
If you're learning how to apply vinyl decal for the first time, it's best to start easy with a smooth, flat surface. Once you're confident with how the process works, that's when you can move on to trickier items with a curved or flexible design, like hats.
Tips for Long-Lasting Vinyl Decals
So, once it's been expertly applied, how can you keep your vinyl decal looking great for as long as possible? There are a few tips that we recommend to achieve this.
Our key piece of advice is to use high-quality vinyl that's designed for fabric (not all vinyls work well on textiles!). Check that you've bought a heat transfer vinyl before you apply it. Avoid using outdoor vinyl, like the kind you might see on a car window or a mug, as this won’t hold up on fabric.
Once you've applied it to your item, it's wise to let the decal sit for at least 24 hours before you think about washing or stretching the fabric, so the adhesive has time to cure. And speaking of washing, when you do need to clean your decalled clothes or hats, the safest option is to wash them inside out in cold water and air dry them. Strictly no fabric softener, bleach, or high heat in the dryer, since these all wear down the adhesive faster.
Now you know how to apply a vinyl decal in a way that lasts, you might be in the mood to shop for some new decals for your gear. Check out our selection of decals at Notch Gear—we're sure you'll find something you'll love.
