A half-circle arch derives its name from its shape. This style of arch is reminiscent of Spanish and Tuscan architecture that is often related to bring a warm cozy feel to a home.

How to Drywall a Half-Circle Arch Kit
Drywalling a half-circle arch is comprised of measuring the curvature of the arch, cutting the drywall to the curvature and depth, forming and fastening in place.
- Wetting the back of the drywall (as shown in the video) will make the drywall easier to bend.
- For tighter radius half-circle archways, consider using a double layer of either ¼” or ¼” flex drywall.
How to Finish Half-Circle Archways
Drywall, plaster, wood veneer, brick veneer, trim, tile … the list is seemingly endless. Whether you want your half-circle archway to have a simple or an ornate finish, the choice is yours.
Half-Circle Archways Specifications
|Material||Medium Density Fiberboard (MDF)(High Grade Moisture Resistant)|
|Thickness (in.)||1” – 1 ½” (depending on width)|
|Depth (in.)||1” to 5 ½” Depths over 5 ½” will be made as a 2 piece split. A 2 piece split is a 5 ½” deep arch with a split cut down the center. When installing, finish the split cut and put one 2 ¾” piece on the front and the other 2 ¾” piece on the back of the opening.|
Finding Your Half-Circle Arch Rise
To find the rise of a half-circle arch, simply divide the width of the opening by 2. For example, a 74 ½” wide opening would have a 37 ¼” rise (74 ½” / 2 = 37 ¼”).
