How to Build an Archway

An archway is a common passageway in Mediterranean architecture. An archway is a standard passage between rooms that has an arched top. Archways may seem difficult to create, but they are relatively simple to complete if you are familiar with working with drywall. This task can be completed in less than 24 hours.

Things You'll Need

• Tape measure
• Template paper
• Pencil
• Push pin
• String
• Scissors
• Drywall saw
• Drywall mesh
• Drywall tape
• Drywall plaster
• Drywall trowel
• Drywall sanding block

Instructions

1. Measure the width of the door opening where you want to create the arch. Use the tape measure to get an accurate measurement.

2. Tie one end of the string around the pencil and the opposite end of the string around the push pin. Wrap the string around the pencil until the length between the two ends is half of the width of the opening. For example, if the door opening measures 36 inches, wrap the string around the pencil until it is 18 inches from pencil to pin.

3. Lay the template paper on a flat surface. Stick the push pin through the center of the template paper and draw a circle. Use the string to guide the pencil around the template paper in a true circle. Remove the pin and cut the circle from the template.

4. Fold the circle in half to create a half-moon template. Place the center fold over the top edge of the door opening and trace the half circle onto the wall with a pencil. Remove the template and repeat this drawing process on the opposite wall in the opening.

5. Cut out the half circle traced on the wall with a drywall saw. Cut slowly to avoid breaking the drywall during this process.

6. Apply drywall plaster with a drywall trowel around the arch cut into the wall. Apply drywall mesh over the opening and tape it down on each end with drywall tape. Apply drywall plaster over the tape and mesh to seal it in place. Allow the drywall to set for 2 to 4 hours or until hard.

7. Sand away excess drywall plaster using a drywall sanding block. Apply a second coat of drywall plaster if mesh or tape shows through the remaining layer of plaster. Sand away gently to avoid exposing tape and mesh. Paint over the arch area when finished.
