The process of finishing a room is filled with many steps that most people never knew existed, and includes the process of installing something called drywall corner beads. Most people take for granted the fact that their corners are seamless, and do not realize the effort that went into creating them. Corner bead is a thin piece of steel bent at a 90 degree angle down it’s length which covers the gap between sheets of drywall where they meet at an outer corner.
If you are building a house or finishing the basement, you should be able to properly apply drywall corner bead. It will make your rooms look better and more professional. So here are a few ways you can apply drywall corner bead like a pro.
Cut the drywall corner bead to the exact length that you will need. It is not a good idea to use more than one length per wall, so purchase long pieces and use a new one for each corner. It does not matter if you have some leftover scraps at the end.
Measure with an accurate tape measure, then cut it with a pair of metal shears so that you get a clean cut and no fraying at the end. Hold it up to the wall and make sure that it is exact and that it fits how it should (with a nice and tight right angle). If it all fits together perfectly, then you are ready to affix it to the wall.
To hold the drywall corner bead in place for a moment, simply use a tack or pin to affix it. Make sure that you are happy with everything about it before you make it permanent. If it does not fit right, it will be visible for the rest of the existence of the room.
This is not the sort of permanent blemish that you want attributed to your shoddy workmanship, so be sure to take your time and get it right. You should tack the paper down every foot or so all the way down the length of the wall before you begin to apply the mud.
Applying the Mud for Drywall Corner Bead
Applying the mud is the messy part of installing drywall corner bead. It might have come with the bead itself, or you may have had to buy it separately. Using a large, flat putty knife you can spread the mud onto all of the places where the drywall corner bead transitions into wall.
You should slather it on rather thick with the putty knife, and then scrape the bulk of it off. You will end up with a thin, smooth layer of mud to hold on the drywall corner bead.
After you have the drywall corner bead applied to the wall with mud, you have to wait for it to dry. Remove all of the tacks you used to keep the bead in place. Now you will have a slightly unsightly feature on your wall. Therefore, as soon as the mud has dried properly and the drywall corner bead is not going to fall off at all, sand it smotth so it blends well and then it is ready for painting along with the rest of the room.
If done correctly, the bead will be completely indistinguishable from the rest of the wall once you are done. If you have any problems with getting the bead to look good, or problems applying the mud, then consult someone who has had experience with the steps of drywalling a room.
