Now it’s very easy to do this fast like the pros. Just make sure the edges of the sheetrock are nice and straight and even.
Use 1 1/2 long roofing nails or better yet, drywall nails. Don’t nail the nail in so hard that the corner bead is pushing out around the edges. Just tight.Start with a 6-inch taping knife and then after the first coat dries you can either use the 6 inch again or go right a 10 inch. And that’s how you install a corner bead on a sheetrock edge.
