I admit it, I am frugal. That is one way of saying that I really despise waste. A standard construction tube of caulking often contains way more material then a typical home owner project will use at one time. So the remainder of the tube becomes waste if it sits around too long.
I have tried every trick in the book to preserve the life of caulk tube remnants. I have put electrical tape over the nozzle. I have tried to embed nails and screws so that there is a channel when I come back to it. I have cut the nozzle shorter to pull the plug of dried caulk out. I have used large, screw on electrical connectors to act as a cap. They all suck.
Caulking is a love hate relationship. You want to believe that it is an ideal solution to a less than ideal situation. That being said, I find about a five year or less life with it in an outdoor application. My personal preference is to use as little as possible because if you are at the point where your hopes are on caulk, you are waiting to fail.

Certain projects typically can use quite a bit of caulk. I am thinking back to siding replacement I did a couple of years ago. In those cases, it seemed like I was going through it as fast as I could blink. But, because I despise waste, I want to make sure that I am purchasing the exact amount I need. Caulk will even dry up in an unopened tube and when you only use a squirt at a time, it doesn’t pay to keep it around.
Recently, I was doing a quick cleaning to get ready for a house showing. I hadn’t really spent any time in the apartment since the tenant moved out. It looked like it was in the need of TLC and when I looked at the vanity, I could see a gap between the top and the tile backsplash. I can’t remember if I ever mentioned this but we had to replace the entire floor a couple of years ago. The shower had leaked and it had rotted the structure. So, the vanity had to be removed and I suspect it shrank.
I thought that I would just quickly put a bead down. The more I can spruce up, the better the chances the buyer will be wowed, or at least not turned off. I had an open tube of kitchen/bath caulk. The best application for this is 100% silicone, that is not wholly important other than to say it is not water based. It requires mineral spirits to clean up.
In fact, I had two tubes. One was clear and the other is white, see picture above. The clear one had clearly given up the ghost. I determine that by forcing a nail into the small opening at the nozzle. If and when I pull the nail out and I get some still wet material, then I consider the tube viable. I would then set about trying to get at the good material.
The clear was clearly dried out, but the white was not. So, I set about poking and squeezing until it was flowing. If I can get away with it, I will cut half the nozzle off but that amount of opening causes a very wide bead. That tactic is not really suitable for a for a bath job unless you are OK with it all over the place. I was not.
Twenty minutes of poking and cleaning my hands and tools off with mineral spirits, I finally got it to flow at an adequate rate. Believe me, more than once I had this thought that I am spending way more money in time than just going to purchase a replacement tube. The nagging problem in my head is that this perpetuates the cycle all over again. I had to get it done quickly because I had 30 minutes before the showing so I persisted. Fortunately, I felt like the smell of bleach that I poured around the shower to try and subdue the mildew significantly overwhelmed the pungent, vinegary smell of silicone caulk or the petroleum smell of ‘Odorless’ Mineral Spirits.
The job got done and I screwed the electrical wire nut back on the nozzle. I know full well that the next time I want to do something like this again that this tube is likely shot at 3/4 full. I was lucky to get a second project out of this one as it is.
End Your Programming Routine: I used to keep a small tube of hand squeezable caulk. However, it also dried up. Just like we are buying half gallons of milk now, these things can almost cost as much as a standard tube. But, at least there is not so much waste. Now that we are moving to a newer house, I am expecting less home improvement projects. Maybe it is time to go back to the smaller tube?
