– Hey everyone, welcome to part two of how to tape and mud drywall joints, or mud and tape. How to tape the joints, it’s called sometimes. First part of our video we talked about how to do beveled joints and how to do sanding. Dustless sanding, actually. There’s a link at the end of this show to watch the first show, or there’s a link right below here as well. This is part two, we’re gonna be talking about butt joints and corners. So to do an inside corner like this, we’re going to use paper tape. I like to use fiber tape on regular joints. Corners, inside corners, I like to use paper tape. And it has a built-in crease in it here, you can see that.
You can just pinch it like this and it creases like that. Nice, huh? So we’re gonna put that crease in there. You wanna make this the length of your corner. And then this is one of those controversial tape jointing things. I like to moisten the paper tape a little bit, I just like it to be a little wet like that. That was our sponge, our magic sponge. The other tool we’re gonna use is a corner knife. These aren’t cheap, they’re not real expensive, but they’re a time saver and a labor saver. So go buy one, or borrow one, maybe one of your friends has this. ‘Cause you use it maybe once every five years, okay? Corner tool, really nice.
Okay, we have our joint compound. Again, it’s the consistency of cupcake frosting or really thick mayonnaise maybe. But we’re gonna, essentially like with brick laying, we’re gonna butter the joint. So we’re gonna put it on both sides of the corner like that. And then we’re gonna take our paper tape and lay it in. By the way, I like these gloves when working with this. And then I’m gonna add some more mud on top of that joint.
I might’ve put a little too much mud below the tape. So there you go. Probably should’ve put a little less on the first base coat. Lay this in, press in. Hold it at an angle and go down like that. It took off quite a bit. After this first patch, you can go back and just knock down that edge. This is what’s called an outside corner.
That is an inside corner, we talked about that with the tape. Outside corners, I like to use metal corner bead. It’s held in somewhere here. Alright, some drywall screws, not too many. You want those flat as you can get them. I like this because if you dig into this with the vacuum or your dog or moving furniture, it’s metal, and this gets painted and it goes white or whatever color your wall is.
But if you just use paper here, it would crack and you’d have joint compound and have to do a repair. The metal is more resilient. So this stuff comes in, like, ten-foot lengths. It’s really sharp edges, okay? Be careful. Learn from me. So I’m gonna do a side shot here to kind of show you how this works. I don’t know if it’ll work in the camera, we’ll find out. Bring this up. Put on more than you think you need, it’s always okay. The cool thing about joint compound is you can always redo it. If it doesn’t look right you can pull it off and do it over. It’s kind of like with, there’s a big, what’s that called? The “undo” button on your computer. Joint compound is the big “undo” button, alright? Clean blade, pull this up and over.
Well, just pull it up. And this stuff on the side, just scoop it off. The really small stuff, when it dries, you can just knock it down. See how it just covers right up those drywall screws that are in there? Then you just take your blade. And again, one part of your blade rests right on the metal edge there. (whispers) Oh, that’s really cool. Clean your blade, and you can fix this little extra part here. Just kind of favor, you wanna feather this, so pressure on the sheet rock side and just angle it slightly, like that. Corners, pretty straightforward with that corner tool there. Butt joints is another story. This is typical here, we had some existing sheet rock, we added new sheet rock, and you and your friends maybe didn’t get it perfect.
You know, the ideal is they line up like this, but it might’ve been a little off like that. You get the idea here. So we wanna make this a little more accepting, so we’re gonna do a little trick I’ve learned, and that is to cut a bevel. Much like the sheet rock ends are pressed in a little bit, we’re gonna cut a little bevel in here. You wanna get the sharpest blade you have, utility knife. These are a little less reliable, these don’t slip as much. But we’re going to cut these edges, and we’re gonna cut an angle on them. So we have a really sharp blade. So instead of having these hard right angles here, we’ve cut this bevel, so it’s gonna be a little smoother going across. So I’m gonna lay in some mud in there, doesn’t have to be beautiful.
And then I’m gonna lay in this tape. And I’m gonna lay some more mud on top, and that’s our first coat. So here’s our butt joint that we did the bevel on and we put the fiber tape in. Just gonna knock down the high points here. So for our additional coats, we go beyond the feather. You know, we went from here to here, now we’re gonna go from here to here.
So we bring out more junk. Take out the junk and throw it away. Then bring our blade up. So there you go.
