Place two caps on top of the wall, spaced so a third cap will fit tightly between their widest point
Mark the overlap on the bottom of the center cap
Cut cap on marks to fit between caps
Capping a curved wall takes a bit of cutting and fitting, but produces a beautiful finish. Be sure to wear safety glasses when cutting, and operate power saws carefully.
Measure the distance of the gap between the 2 caps (x) at the front of the wall
- Place two caps on top of the wall spaced so a third cap will fit tightly between their widest point.
- Set another cap on top of the first two caps and mark where they overlap on the bottom of the center cap.
- Remove the center cap and cut along the marks.
- Set the middle cap back in place so the three fit tightly together.
- Repeat as often as needed to cap the entire curve.
- It's a good idea to secure caps with a high strength construction adhesive once they are all cut.
- On tighter curves both caps equally will give a cleaner look.
