Frequently Asked Questions

Can I use super glue on my motorcycle helmet’s EPS foam liner?

No. Super glue (cyanoacrylate) can melt or dissolve EPS foam, destroying its safety properties. Use foam-safe adhesives like Shoe Goo or specific foam-safe epoxies.

How do I know if my helmet repair is safe or if I should replace it?

If the damage involves the EPS liner (cracks, compression) or the main structural shell has a deep crack from an impact, replace the helmet immediately. Adhesives are for cosmetic repairs, trim, vents, and interior comfort pads only.

What’s the difference between epoxy and super glue for helmet repairs?

Super glue is for quick, tight-fitting bonds on hard materials. Epoxy fills gaps, takes longer to cure, and generally provides a stronger, more durable structural bond suitable for varying temperatures and vibrations.

Will adhesives damage my helmet’s paint or graphics?

Some solvent-based adhesives can soften paint or cloud clear coats. Always use masking tape to protect the area around the repair. If in doubt, test a small drop in an inconspicuous area.

How long should I wait before using my helmet after making a glue repair?

Follow the manufacturer’s “full cure” time, not just the “set” time. For most epoxies and flexible glues like E6000, this is 24 to 72 hours. Riding before a full cure can cause the bond to fail due to wind pressure or vibration.
