Better Way to Save Caulking

About: I like making food and trying food!

This is a quick Instructable to show you a better way to save open caulking. Typically tubes of caulking dry out after a few weeks if not stored properly. The old way was to plug the end of the nozzle with a nail and it works for a few days but if the caulking is stored any amount of time the nozzle will dry out and the tube of caulking basically is useless. I have used this technique on both acrylic and silicone caulking and works for both.

Step 1: Materials and Process

You will need:

  • Rubber band
  • Piece of plastic


  • Wrap the end of the nozzle with the piece of plastic, leaving some room at the very end.
  • Wrap the rubber band around the plastic around the nozzle.
  • Squeeze some caulking into the void that was created when wrapping the plastic over the nozzle.
  • Store the tube somewhere cool.

    I use a hot glue gun to seal the opening with. A copious amount of melted glue, and the tube will keep for months.
