How to Paint an Arch on a Wall
A painted arch accent wall is easy to create and adds character, a nice retro vibe, and soft curves to any room. This interior painting trend continues to make waves in many living spaces. Discover how to make your own in just a few simple steps!
Select a Design
- 1.1 - The number of arches depends on the space, the area to be covered, and the desired look. For example, a single arch can accentuate a piece of furniture (such as a desk, nightstand, or dresser). On the other hand, a combination of arches will create a trendy accent wall.
- 1.2 - When it comes to height, we recommend not going over the door frames (7’ height). When creating your design, keep in mind that to get a perfect arch, the height of the semicircle must be exactly half the width. For example, if you want an arch that’s 6’ tall and 2’ wide, you’ll need to trace the two vertical lines all the way up to 5’ from the floor. However, there are other less traditional types of curves.
- 1.3 - Either way, preparation is key! It’s always a good idea to draw a line on the wall before you start. You can also take a photo and use an online drawing tool to sketch it and see the effect.
Trace the Vertical Lines
- 2.1 - Starting from the floor, measure the space from side to side and divide by the desired number of arch strips.
- 2.2 - Mark each section with a small piece of tape or a pencil, making sure to space the arches evenly (unless you’re looking for that overlapping look).
- 2.3 - Using a level, mark all vertical lines at a few spots with a pencil.
- 2.4 - Once all vertical lines are marked, apply masking tape outside the arches that will be painted first (here, arches 1 and 3).
Trace the Semicircles
- 3.1 - Measure the width of the first arch strip and divide that number by 2 to find the centre. Mark it with a pencil.
- 3.2 - Cut a string to the length identified above, plus 1-2” extra.
- 3.3 - Tie one end of the string around the tip of a pencil.
- 3.4 - Tape or thumbtack the other end at the centre point of the arch (previously marked).
- 3.5 - Place the tip of the pencil on the wall at the end of the first vertical line then slowly move the pencil up and over the centre point, making sure the string is extra taut at all times, until you reach the end of the other vertical line.
- 3.6 - Repeat this step for the other arch strips.
- 3.7 - Contour the semicircles of arches 1 and 3 with masking tape.
- 3.8 - Using an all-purpose knife, lightly trace over the pencil line then peel away the bits of tape.
Paint Arches 1 and 3
- 4.1 - Place a drop cloth on the floor and add masking tape to protect the baseboard.
- 4.2 - Use a paint brush to trim along the baseboard.
- 4.3 - Use a roller to fill in the inside of arches 1 and 3.
- 4.4 - Repeat the steps above for second coat and let dry completely.
- 4.5 - Remove the tape around arches 1 and 3, then allow the paint to dry.
Paint Arches 2 and 4
- 5.1 - Apply tape to protect arches 1 and 3.
- 5.2 - Repeat steps 4.2 to 4.5 for arches 2 and 4.
