Super Glue + Baking Soda = Instant Filler That’s Rock Hard
Another handyman secret weapon. When you mix super glue with baking soda, the baking soda acts as an accelerator — the glue cures almost instantly and becomes incredibly hard. Harder than most plastics. You can sand it, drill it, and paint it.
The Technique
- Apply super glue to the repair area
- Sprinkle baking soda over the wet glue
- The combination hardens almost instantly
- Build up layers as needed — glue, baking soda, glue, baking soda
- Sand smooth once fully cured
What It’s Good For
- Filling gaps and cracks in wood, plastic, and metal
- Rebuilding broken screw holes
- Repairing chipped corners on furniture
- Bonding pieces where regular glue doesn’t hold
- Creating custom filler that matches sanded surfaces
Tips
- Use thin super glue (not gel) for best penetration
- Build up in thin layers rather than one thick application
- The bond is stronger than many of the materials it’s repairing
- Can be sanded, drilled, and painted once cured
