🔎 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!
