Examine Different Types of Air Bubbles

going to show you what i'm talking about you might be wondering what the heck are you talking about air bubbles in my caulking and i'd have to say like probably 10 years ago this was never an issue it's really rare that you would get an air bubble in a tube of caulking and as a professional painter you know we're accustomed to using the terminology a pop and an air bubble in a tube of caulking is what we call a pop i'm going to show you a um tuba caulking and this is dap and you know this is probably one of the cheapest tubes of caulking you'll ever buy um it's cheap inexpensive not very good it doesn't bond stick it cracks really easy but it's affordable and a lot of people want it because it's affordable here's what we call an air bubble now these are tubes of caulking we cut them open brand new wet and they're dried now but here's an air bubble inside this tube of caulking that's a very large air bubble when you take in um when you're uh pulling the trigger on your caulking gun it's pushing on this air bubble and it's causing it to compress it's pushing caulking out and expelling caulking out of the tube but this air bubble inside the caulking is gonna it's gonna continue to expel caulking out of the tube and it's gonna make the dripless caulking gun not function so air bubbles are very annoying now this tube of caulking the air bubble is all the way in the back it will continue to drip caulking until that air bubble comes out here's another tuba caulking here's a tube of nr4000 it's got not quite as big of um air bubble but there's an air bubble right there it also has an air bubble at the top that that air bubble is going to get expelled right away and if that was the only air bubble in there it would discontinue dripping or expelling caulking you know out of the tube when that air bubble comes out one of the very annoying things about these air bubbles is when they do come out that's where the term pop comes you'll be squeezing the trigger and it goes pop and it splatters caulking out the tube sometimes in your face sometimes on the floor it invariably it goes where you don't want it to go so you got tubes in the top or um bubbles in the top and bottom which is kind of the double whammy you know with that tuba caulking i've got another tuba caulking that i cut open right here so this one's got there's no air bubble in the bottom but we got an air bubble in the top so as soon as it expels that air bubble it's going to function properly in a dripless…
