Simply insert the nozzle tip of the caulk tube into the wax several times until a good seal has formed inside of the nozzle. Wipe off any excess wax from the outside of the caulk tip and store the tube in a cool dry place for later use.

​

To reuse the caulk tube, just place it back into the gun and squeeze the trigger until the wax seal is pushed out and the caulk begins to flow.
