Fabric Glue vs Hem Tape: Which One Works Better?
August 22, 2025
🧵 Why Won’t My Wonder Web Stick?
Wonder Web is designed to create strong, no-sew hems — but sometimes, users find the bond doesn’t hold as expected. Don’t worry — this usually comes down to application issues, fabric choice, or heat settings.
Here are the 7 most common causes (and fixes!) for Wonder Web not sticking.
âś… 7 Reasons Why Wonder Web Might Not Stick (and How to Fix It)
1. Not Enough Heat
- Cause: Iron not hot enough to melt the adhesive.
- Fix: Use the cotton/wool setting with a damp pressing cloth. Hold for 10–15 seconds in each section.
2. Iron Moved Instead of Pressed
- Cause: Sliding the iron weakens adhesion.
- Fix: Press firmly, lift, then move to the next section — don’t drag.
3. No Damp Cloth Used
- Cause: The adhesive activates with steam, not dry heat.
- Fix: Always use a damp cloth or tea towel over the fabric.
4. Wrong Fabric Type
- Cause: Wonder Web works best on cotton, polyester, blends, and light denim. It won’t hold well on silk, velvet, or very stretchy fabrics.
- Fix: Check fabric type before applying.
5. Fabric Wasn’t Pre-Washed
- Cause: Fabric finishes or sizing block the adhesive.
- Fix: Wash and dry before hemming.
6. Not Enough Cooling Time
- Cause: Moving fabric before adhesive sets.
- Fix: Let the hem cool completely before wearing or washing.
7. Tape Too Narrow for Heavy Fabric
- Cause: Thin tape won’t support denim or thick curtains.
- Fix: Use 20mm Wonder Web Extra Strong for heavy fabrics.
🎯 Bonus Tip: How to Make Wonder Web Last Longer
- Wash at 30–40°C
- Turn garments inside out
- Avoid bleach and strong detergents
- Air dry or tumble on low
