10 Best Glues to Stick Metal and Plastic — Ultimate Guide for Unbreakable Bonds
Ever Tried Gluing Metal and Plastic? Here’s the Truth…
You grab your favorite super glue, fix your broken handle, and — snap! — it falls apart in minutes.
Sound familiar?
That’s because metal and plastic aren’t meant to bond easily. They expand differently, repel each other’s surfaces, and most ordinary glues simply don’t grip well enough.
But don’t give up just yet.
With the right adhesive, you can create a bond so strong that it feels welded — waterproof, heat-resistant, and long-lasting. Whether you’re repairing, crafting, or building something from scratch, this guide reveals the 10 best glues for sticking metal to plastic that actually work.

How to Stick Plastic to Metal Like a Pro
Even the world’s best adhesive won’t help if you skip the basics. To get an unbreakable bond, follow these pro tips:
1. Clean the Surfaces
Oil, grease, and dirt ruin adhesion. Wipe both metal and plastic with alcohol or acetone before applying glue.
2. Roughen the Surfaces
Use sandpaper to lightly scuff both surfaces — it gives the glue more texture to grip.
3. Apply Evenly
A thin, uniform layer is better than a blob. Too much glue weakens the joint.
4. Clamp or Press Firmly
Hold both parts together tightly while curing. Use clamps or tape if possible.
5. Give It Time
Fast-setting doesn’t mean instant strength. Let it cure fully (typically 12–24 hours) before testing the bond.
