Introduction
The HeatnBond Hem Iron-On Adhesive is a double-sided, heat-activated adhesive designed for permanently hemming garments and home decor items without the need for sewing.

Setup
- Pre-wash Fabrics: For best results, pre-wash all materials without using fabric softeners. This ensures optimal adhesion.
- Pre-test Adhesive: Before starting your main project, it is recommended to pre-test the adhesive on a small, inconspicuous area of your fabric to ensure compatibility and desired results.
- Preheat Iron: Set your iron to medium heat. Ensure the steam function is turned OFF.
Operating Instructions
Follow these steps to apply HeatnBond Hem Iron-On Adhesive:
- Prepare Hem: Turn the garment or fabric item inside out. Measure and press the new hemline into the fabric using your preheated iron. This creates a crisp fold for the adhesive.
- Apply Adhesive: Place the HeatnBond Hem tape inside the newly folded hem. Ensure it is positioned evenly along the edge.
- Bonding Process: Place your iron directly onto the fabric over the tape. Hold the iron in place for 3-5 seconds on each section. Slightly overlap sections as you move along the hem to ensure continuous bonding. Avoid moving the iron back and forth.
- Final Press: Once the entire surface is bonded, turn the item right side out and iron the fabric for an additional 1-3 seconds to ensure a smooth, finished appearance.

- Bleach: Do not bleach.

Troubleshooting
If the adhesive does not bond properly, consider the following:
- Iron Temperature: Ensure your iron is set to the correct medium heat setting and that the steam function is off. Insufficient heat will prevent proper activation of the adhesive.
- Pressure and Time: Apply firm, even pressure with the iron for the recommended 3-5 seconds per section. Holding the iron for too short a duration or with too little pressure may result in a weak bond.
- Fabric Compatibility: This regular weight adhesive is best for light fabrics. For heavier fabrics like denim or corduroy, consider using HeatnBond Hem Super Weight adhesive.
- Fabric Softener: Ensure fabrics were pre-washed without fabric softeners, as these can interfere with adhesion.
