Hot Tip for Caulk Tubes

Sealing an open tube with hot-melt glue provides a quick fix to a pesky problem.

By Charles Miller Issue 305 - Feb/March 2022

Saving partially used tubes of caulk used to be a problem for me. I would try to seal the spout with a nail or even a dedicated cap, but inevitably the unused caulk would solidify over time and become unusable. I now seal the open spout with a dab of hot-melt glue. It conforms to the opening and hardens quickly, providing an airtight seal. The resulting plug can be removed easily for the next caulk application.
