How To Store Caulk []


I was wondering if there were any tricks to keep tubed caulk and other such things from drying up, when you don't use the whole tube but want to reuse the rest?


The proper way to store caulk – open or not yet opened – is in the upright position. Once opened, the caulk material is designed to cure with the presence of air, and an opened caulk tube lasts a short time depending upon ambient temperature.

To seal an opened tube, squeeze some caulk out of the end of the tube about 1/4″ of an inch, then slide a nail or wire into the tube with an abundance of caulk around the nail to minimize air leak into the tube, then store the tube upright. The caulk seals the tube spout and the nail provides a handle to pull out the cured “slug” of caulk when later use is desired. This is the best storage method I have found.
