what glue works on metal
What glue works on metal?
The short answer: **epoxy** is usually the strongest all-around choice for metal, while **super glue (cyanoacrylate)** is best for fast, small repairs. Metal surfaces are non-porous, so the best results usually come from an adhesive made for metal rather than a generic household glue.Best options
- Epoxy: Best for strong, durable bonds and larger repairs; it’s a top pick when you need gap-filling and toughness.
- Super glue: Good for quick fixes and small metal-to-metal joins, but it does not fill gaps well.
- Polyurethane glue: Works on metal in some mixed-material jobs, but it’s usually not the first choice for metal-only repairs.
- Contact adhesive or hybrid construction adhesive: Useful for certain project types, especially if you’re bonding metal to another material and need some flexibility.
What to choose
If you want the strongest practical option for most DIY metal repairs, go with a metal-rated epoxy. If you need a quick bond on a small, clean, tight- fitting part, super glue gel is often enough.
Quick tips
- Clean the metal well.
- Dry it completely.
- Lightly roughen smooth surfaces if possible.
- Clamp or hold the pieces still until cured.
Simple rule
- Fast fix: super glue.
- Strong repair: epoxy.
- Mixed materials: hybrid or polyurethane adhesive.
