During the drywall process, we get ready to do the next application and that can vary from each individual to each individual. The next thing we're going to be talking about is a tool that will be used before painting. This item here is called a caulk gun. A caulk gun holds tubes of caulk, liquid nail, many different styles of tubing are designed for this type of gun for many different applications. If you're putting down subfloors, you might want to use a bigger gun and that comes with more sufficient size tubes for the application that you're using. This here is a very standard caulk gun. The caulk gun opens by pushing the back of it and then you pull the handle and it opens like this. Here you turn around and you have a cutter. With this cutter you take and put your tube in, you cut your piece and off it goes. Some tubes need to be pushed in with a metal pin that's sticking out here which helps puncture the seal inside the tube. Other tubes don't. A lot of the painting tubes that you come across nowadays don't have the foam on the inside, all you have to do is just cut it, insert it, snug this up to where you need it and then apply pressure as needed. Some guns you will have to press the button to release the pressure off of it, otherwise the stuff will keep squirting out. So out of habit on all guns, I turn around and when I get finished, I hit the button regardless of what type of gun that it is so that I do not have the pressure or the mess afterwards.
