🔎 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!
