How to Iron On Patches
Iron on patches are easy to apply at home with a normal household iron, or in seconds with a heat press. Follow these steps for a patch that stays put wash after wash.
What you need
- Your iron on patch
- A household iron with the steam turned off, or a heat press
- A thin cotton cloth or pillowcase
- A firm, flat surface such as a table with a towel on it (an ironing board is often too soft)
How to iron on a patch with a household iron
- Prepare the garment. Wash and dry it without fabric softener, then iron the area flat.
- Heat the iron. Use the cotton setting with no steam and let it heat up fully.
- Place the patch. Put it adhesive side down exactly where you want it.
- Cover and press. Lay the cloth over the patch and press down firmly for about 30 seconds. Hold the iron still. Do not slide it, or the patch can move.
- Press the back. Turn the garment inside out and press the back of the patch area for another 20 to 30 seconds.
- Let it cool. Leave it flat until it is completely cool. The glue sets as it cools.
- Check the edges. If an edge lifts, cover it and press that spot again.
How to apply a patch with a heat press
A heat press gives the most even heat and pressure. As a general guide for iron on fabric patches, use 150 to 160°C (302 to 320°F) with medium pressure for about 15 to 20 seconds, then press the back for a few seconds. Some products need different settings, for example:
- 3D silicone patches: 150 to 160°C for 25 to 30 seconds with medium pressure.
- Flock patches: 150 to 160°C for about 10 seconds, peel the film when cool.
- Heat transfers: 150 to 160°C for about 10 seconds, peel the film when cool.
Always follow the instructions that come with your order, and test on a spare piece of fabric first if you can.
Fabrics to avoid
Do not iron patches onto nylon, polyester with a waterproof coating, leather, vinyl, rayon or very stretchy sportswear. The heat can melt or mark the fabric, and the glue will not bond well. For these, choose sew on or Velcro backing. See patch backing types explained.
Common mistakes
- Using steam, which stops the glue from bonding.
- Pressing for too short a time or too lightly.
- Moving the garment before the patch has cooled.
- Ironing onto a curved surface such as a cap. Sew hat patches on instead.
- Washing too soon. Wait at least 24 hours before the first wash.
Make it last
Wash inside out on a cool cycle and avoid tumble drying. For items that are washed very often, add a few stitches around the border for a permanent hold. Ready to order? Browse our custom iron on patches.
Frequently asked questions
How long do you iron on a patch?
With a household iron, press for about 30 seconds on the front through a cloth, then 20 to 30 seconds on the back. With a heat press, about 15 to 20 seconds at 150 to 160°C for most fabric patches.
Should I use steam?
No. Turn the steam off, because moisture stops the glue from bonding properly.
Why did my iron on patch fall off?
Usually the heat or pressure was too low, the iron was moved, the fabric was unsuitable, or it was washed too soon. Press it again, or add a few stitches.
Can I iron on a patch twice?
Yes. If an edge lifts, cover it with a cloth and press that area again.
Can I iron a patch onto a hat?
It is not recommended because a curved crown does not get flat, even heat. Sew it on instead.
