Super glue is a really versatile and useful product, perfect for a quick fix. It’s only downfall is that it is quite thin and so cannot be built up around joints or cracks for additional support, this hack addresses that problem.

Enter baking soda! Mixing baking soda and super glue create an hard, drillable and sandable filler. It sets and hardens to its full strength really quickly so you’ll need to plan ahead and work quickly.

What You Will Need

  • Super Glue
  • Baking Soda
  • A Small Brush

Endless Applications For Super Glue

Brush or pour the baking soda dust into the crack or around the edges of the joint you are trying to mend then drop some super glue onto the baking soda. The baking soda absorbs the glue and in a few seconds forms a strong reinforced seam. You can add multiple layers if needed.

If you are filling larger cracks or gaps, alternate layers of glue and baking soda until the crack is filled. Allow a couple of minutes between layers for the glue to fully harden. Make sure that the glue fully soaks into the baking soda with each layer without and excess glue or baking soda as seams of of glue without baking soda become brittle and seams of baking soda without glue create voids which weaken the joint.

Allow the glue to fully cure for about an hour or so before sanding or filing.

This glue and baking soda mix is really versatile and can be used to repair models, cars, boats, household items or for crafts.

Acetone or nail polish remover can be used to clean up any excess glue.
