Step 1: Cutting the Plywood Strips

Determine the size and layout of your arch walls. Cut vertical strips of plywood according to your measurements. Each strip should be 7 inches wide. If your ceilings are more than 8 feet tall, split the strips into 2 sections each.

Step 2: Cutting the Arch

Cut the plywood down to the size of the arch diameter. Use a string tied around a screw in the center to draw a perfect circle on the plywood. Cut out the circle using a jigsaw. Sand down any imperfections along the edges of the arch.

Repeat the process for the drywall to get matching pieces. Use the plywood arch cutout as a template to trace onto the drywall. Cut along the traced line with a jigsaw.

Step 3: Attaching the Plywood to the Wall

Starting at one end, screw the first vertical strip into the wall. For exterior block walls, regular drywall screws can be used to secure the strips. For interior walls, try to hit the studs whenever possible.

Step 4: Attaching Drywall onto the Plywood

Line up the drywall and screw it into the plywood. Ensure screws are added near the edge of the drywall to avoid gaps between the two pieces.

Step 5: Mudding and Taping Drywall Seams

Use drywall mud and tape to join the seams where two pieces of drywall meet. Patch the screw holes with drywall mud.

For the drywall seam along the inside of the arch, cut notches along a strip of tape to bend it around the curve.

Step 6: Adding Corner Bead

Use flexible corner bead to curve around the outside edge of the arches. Attach the corner bead with nails, screws, staples, or adhesive. Feather out the small lip of the corner bead by adding multiple layers of drywall mud.

Step 7: Sanding and Skim Coating (Optional)

Sand the arches with a sanding block until smooth and even. If your wall texture underneath is textured, consider skim coating for a uniform finish.

Prep the walls by sanding with an orbital sander to knock down raised areas. Apply pre-mixed drywall mud with a large pool trowel in 2-3 coats to cover textured walls. Smooth out the texture with each coat until the surface is even. Allow each coat to dry completely before applying the next.

    Congratulations! Your arched wall looks great, I love the window and ceiling too, it looks like it is going to be a truly inspired room when it is finished, please post pictures when it is done. I do have a question, since your arches go to the floor, I am wondering how you plan to finish the floor. Molding can be removed and then replaced after a new floor is laid but it seems that is not the case for the ends of your arches. I do love the look you have created and am curious about this. Thanks in advance for explaining your flooring idea and how it will 'mesh' with the arches.
