🔎 Why isn’t my Superglue sticking?

5 Common Mistakes (and How to Fix Them with Colle21)

Have you ever bought a Superglue at the supermarket, tried a quick fix… and nothing holds? 😩
It’s frustrating — but don’t worry! In 90% of cases, the problem isn’t you, it’s either the glue itself or how it’s applied.

Here are the 5 most common mistakes – and our solutions with Superglue Colle21, the pro-grade glue you can trust.


❌ 1. You’re using Superglue that’s already dried in the tube

Standard supermarket glues dry quickly… even inside the bottle! The glue gets clumpy, hard to apply, or won’t come out at all.

The Colle21 Solution: Our Cyanoacrylate Superglue won’t dry out in the bottle for up to one year, thanks to its anaerobic formula (it only hardens between two pressed surfaces).


❌ 2. You’re using too much glue

More glue doesn’t mean stronger hold. Too much creates slippery surfaces and weak adhesion.

Colle21’s Solution: With its ultra-fine tip, Colle21 lets you apply tiny drops exactly where needed. No waste, no mess.


❌ 3. You’re not prepping the surface

Dust, oil, moisture… All of these can prevent glue from sticking properly.

With Colle21, always clean and dry the surfaces (a bit of alcohol or acetone works great). It makes a huge difference!


❌ 4. You’re gluing incompatible materials

Some supermarket glues only work on plastic… or only on metal. Not both.

Colle21 bonds it all: plastic, metal, leather, ceramics, wood, resin… One glue to fix everything — much easier!


❌ 5. You’re not holding the parts long enough

Some express glues promise instant bonding… but without pressure, they just don’t hold.

With Colle21, you get a strong bond in just a few seconds under pressure. Hold manually for 10–15 seconds. For complex parts, use clips or our activator to speed it up even more!
