Probably every DIYer or DIYer already knows that if you sprinkle super glue with soda when gluing something together, the joint will be much stronger. But is this really so? What happens to superglue when it gets mixed with baking soda? By the way, you can use finely ground table salt - extra - instead.
Testing baking soda in combination with superglue
Place a small mound of baking soda on the surface. Let's pour super glue on it.
Immediately everything froze. By the way, heat is released and everything heats up. To check the strength, hit the formed tubercle with a hammer.
Quite reliable. No cracking or chipping. If, of course, you strike normally without fanaticism.
Next, pour baking soda into a matchbox and also add super glue.
Let's try to drill and tap the resulting rectangle.
Screw in the bolt.
Holds up pretty securely.
At least you can’t just rip it out with your hands.
Surface gluing
There is a plastic watering can with a crack on the side.
Let's first seal the spill with superglue on the crack.
And then sprinkle with baking soda.
We check the tightness by filling the watering can with water.
Everything is dry, no leaks!
Next, we glue the broken plastic together using the same method.
Spill, sprinkle.
We repeat several times.
In the end, everything is held securely.
Conclusion:
Yes, indeed the connection is much stronger than using just superglue.
Repairs based on such gluing are quite suitable for assemblies and parts where there are no significant loads.
Another huge advantage is that hardening occurs instantly compared to glue based on epoxy resin, although soda and superglue are inferior in hardness. But compared to epoxy, super glue has better adhesion to the surface being glued.
So for quick repairs, I personally don’t know a better and more reliable method yet and I always use it.
