How to Finish an Archway Between Two Rooms

In many modern homes, the doorways or entranceways between rooms often have a rectangular shape. Some people choose to improve this by installing an arch in the doorway. This is done by constructing the frame of an archway with wood and attaching it to the doorway. After this is done, you must finish the archway by applying drywall and painting it.

  1. 1

    Lift a 1/2-inch drywall sheet into position over the frame. Have an assistant trace the outline of the arch onto the back of the drywall sheet. Repeat this until you have marked sheets for the entire archway.

  2. 2

    Cut the drywall sheets with a jigsaw along the trace lines.

  3. 3

    Lift the sheets into position and screw them into the framing with a drywall screw every 6 inches. Drive the screws deep enough that the screwheads are slightly below the surface of the drywall.

  4. 4

    Measure the length and width of the bottom of the arch. Cut a strip of 1/4-inch drywall to fit.

  5. 5

    Spray the strip with water until it becomes pliable, then attach it to the bottom of the archway with drywall screws. Enlist the help of an assistant for this.

  6. 6

    Connect flexible corner beads to the edges of the archway, using a staple gun every 3 inches.

  7. 7

    Apply joint compound to the bottom and sides of the archway with a 12-inch putty knife. Smooth the surface, and allow it to dry for the time specified on the packaging.

  8. 8

    Add two more coats of joint compound to the archway, allowing each coat to dry for the necessary time.

  9. 9

    Sand the archway smooth with a fine-grit sanding block or sandpaper.

  10. 10

    Wipe the surface down with a dry rag to remove the dust.

  11. 11

    Paint the archway with a coat of primer and allow it to dry. Add a second coat and allow that to dry, as well.

  12. 12

    Paint the archway to match the surrounding walls.
