Step 2: Gather the Material

You will need for this project:

- Baking Soda

Step 3: Get Started

The first step is checking if the piece that you want to fix is clean so that the glue stick to it.

For example if you want to filli a gap, grab the baking soda and filli that gap, if you want you can build up layer by layer.

Then apply the super glue on top of the baking soda, you will notice that the small grains of the baking soda will soak super fast the glue and also cure making a rock solid bond.

Last step will be filing to shape, and if you whant paint also.

You can also use this to cure really fast super glue.

    Gas tank repair? Will baking soda and super glue. Work to repair it

    Answer 6 months ago

    In your place I would make a test. Both original tank material and the glue patch, let it soaked on a gasoline recipient and check it out some days (a month would be ideal) later. It may resist the gasoline, but you must assure that the crack/hole/etc. is held together also. And, the fix must be protected against bending twisting and other mechanical forces over the original damage that is to be fixed. Because unless you use specific, industrial grade glue/repair/weld materials, there is no guarantee that it can withstand the normal use of the fixed part.

    I am used to make similar things using Acrylic resin (polymer and cataliser). Will certainly try that.

    Great info. Rapidfix & Q Bond are super expensive glues that do the same thing. Take a look at their MSDS and you'll see they're just cyanoacrylate (super glue) and some filler material (glass dust or metal oxide). Baking soda seems to work just as good.

    This may be waterproof too ! I fixed an aquarium pump with a 1/16 gap and after 15 minutes, I put it in water for about 10 hours running. After removing it, the glue appeared as solid as ever. Using only superglue had failed to stick but the superglue and baking soda worked great.

    If anyone knows if this is a permanent waterproof solution let me know since I know some things can survive a day but not a month or more in water.

    Great instructable! I've used baking soda & superglue on many projects. It forms a super hard patch that can be sanded and painted. It really does set almost instantly. Thanks again.
