Vaulted ceilings can be simple or ornate.
Cathedral, or vaulted, ceilings are raised on the inside to give more headroom and an ornamental look to the room. The edges around the room may be finished with crown molding, which complements the look of the raised ceiling. Crown molding is tricky to install because it is nailed on at an angle. With vaulted ceilings you can install crown molding around the inside of the ceiling so you only have 45-degree angles to cut. You can also cover the sloped edges that lead up to the vaulted ceiling, depending on the look you are trying to achieve.
Instructions
1. Calculate the length of each wall section where you want to install the molding with a measuring tape. For outside corners, the longer part of the mitered edge will be at the top of the molding. For inside corners, the longer edge is on the bottom. Keep this in mind when you cut the molding later.
2. Measure the slopes on the walls leading to the vaulted ceiling with an angle measuring tool. These tools are designed specifically for measuring crown molding angles. Note the angle for each corner you are going to cover with molding.
3. Lay your molding upside down in the miter saw with the saw set to the angle you are cutting. For example, if you are cutting a square corner, set the molding to a 45-degree angle. Align the edge of molding so it fits as it would on the wall. The middle of the crown molding will be exactly opposite the 90-degree corner of the saw. Each edge of the crown molding will sit flush against the walls of the saw.
4. Cut the molding with the power miter saw. If you are working on an inside corner, keep the measurements so the bottom edge is the full length of the molding. Remember that the molding is upside down in the saw.
5. Hold the corner pieces together after you make the cuts to ensure they fit nicely.
6. Install the molding at an angle in the vaulted ceiling so the edges are flush against the ceiling and wall. Align the molding so the miter joints fit snugly together.
7. Drive nails into the top and bottom of the molding with a nail gun every 2 feet. Add extra nails on the studs. Drive the nails deep into the wood so the head can't be seen from the outside.
