Creating bullnose edging in an archway is a beautiful detailing that will enhance the architectural effect of the space. Bullnose edging comes in primarily 2 finishes, square and rounded. A square bullnose edge will create a clean look with sharp angles, whereas rounded bullnose creates a softer, old world style effect to the archway. You can find both styles in a couple of different types of materials, galvanized steel and PVC. Steel is the most durable and will last the longest, and is the only option when working with curves. Depending on the style of your home and your personal preferences, either will create a beautiful effect to the archway, and will reinforce the corners to last. Here you will find the information needed to install bullnose edging.

Step 1 - Install the Corner Bead

Measure the length of corner bead needed. You may need to use several pieces for each side of the archway. For the curve of the arch, you will want to cut the corner bead along the flat side in 1/2 to 3/4 inch intervals, the length equal to the length that the arch curves. This will enable you to bend the corner bead to accommodate the arching contour. Secure the corner bead with drywall screws in 8 to 10 inch intervals. Put a screw in each section of the cut corner bead. Make sure to drive the screws down tight enough that the flat head lies slightly below the surface level of the rest of the surface.

Step 2 - Cover the Screws

With a small amount of mud(joint compound) on the smaller knife, cover each screw head with mud and smooth it over, working the mud into the depression created by the screw head. Scrape away as much excess as possible.

Step 3 - Mud the Bead

Spread a good amount the drywall joint compound along the vertical edge of the corner bead with the drywall knife and smooth out with the wide knife, blending it away from the doorway. Continue spreading and smoothing, until the edge away from the corner is blended as much as possibly into the drywall of the adjoining wall, and it is as even as possible. Your will want a light coat of the mud over the corner bead too, and you may need to do repeat applications to get the desired effect. Let each coat dry completely between coats, or you will just create gouges in the damp mud.

Step 4 - Sand

With the sander, smooth out any ridges and finish blending the mud into the drywall. Use a dry paintbrush to dust off clinging dust. Again, you may need to do another mud coat, let it dry, and sand again. This is a labor of love and the attention to detail will pay off.

Step 5 - Texture and Paint

The final step is texturing and painting. If the walls are already textured, you will want to texture the archway to match. Let the texture dry completely, and finally, primer, then paint the archway.
