Hi! I’m Eric with Johnson Drywall. Today, we’re showing you how to install a drywall. In this segment, we’re going to show you how to put the tape and the mud on the joints in the corner bead. This is my technician Adam. He will show you how it’s done.
You’ll want to spread the mud with a 6-inch knife across the joint and you’ll want to fill it up the recess. There is a recess there. You want to fill it up with mud. Then you’ll put the paper tape over top of the joint. Then you want to wipe it down firmly. You don’t want to leave a bunch of mud on it. You want to wipe the edges down tight and push firmly on the tape when you’re wiping it off.
After you do the flat part, you want to do your angles. Then you’ll fold the corner of the tapes as a crease in the middle which will fall right over the corner and you’ll put that and wipe it down tightly, too. Once you get that all taped, you want to block in your corner beads. That will be spreading mud on the corner bead. You want to wipe that down tight too. You don’t want to leave an edge. So, when you spread your mud on, just wipe it down firmly and that will fill up the recess.
Then you want to spot your nails with one coat on your screws and your nails. You’ll wipe down one coat and wipe that down very tight. You don’t want to leave an edge.
Now that we’ve finished our tape coat, we’re going to go into the block coat. We’re going to show you how to spread the mud over the tape. When you start to block coats, you want to put your 10-inch knife on the joint that you taped and let dry and you’re going to see there’s a recess.
All you want to do with the block coat is fill in the recess so you’ll scoop the mud out of your pan and spread it across the joint where you taped and just wipe it down, wipe it at both edges, top and the bottom edge smooth. You do not want to leave a big edge. Then you’ll press down the middle to just fill in that recess, that’s in the drywall.
Once you’ve done that, you’ll go to your angles. You want to run your angle with a 4-inch knife and you’ll do the same thing. You’ll spread the mud over top of the one side of the angle and to wipe further the edge down, take off the edge. Then you’ll wait to do the other side once you go to your skim coat.
So you’ve just run one side of the angle at a time and you’ll whip it another coat of mud on your nails. You’ll spot the nails and screws one more time again. So, that’s your block coat. Now that our block coat is finished and dried, we’re going to go and to show you how to do the skim coat.
