Here’s the short, direct explanation of super glue + baking soda:
Super glue + baking soda = instant hardening + strong filler
When you combine:
-
Super glue (cyanoacrylate)
-
Baking soda (sodium bicarbonate)
They react instantly and form a very hard, rock-like material within seconds.
What it does
✔ Fills gaps
✔ Repairs cracks
✔ Strengthens weak joints
✔ Rebuilds missing corners
✔ Works great on many plastics (except PE/PP)
It becomes hard enough to sand, drill, and shape.
How to use
Method:
-
Sprinkle baking soda on the area.
-
Drop super glue onto it.
-
It solidifies immediately.
-
Repeat to build up layers.
