When cutting outside corner molding, there are a few steps you can follow:
1. Measure the length of the wall where the molding will be installed.
2. Cut the molding at a 45-degree angle using a miter saw or miter box.
3. Hold the molding against the wall to check the fit.
4. If needed, make adjustments to the angle of the cut until the molding fits snugly.
5. Once the cut is accurate, apply adhesive to the back of the molding and press it firmly against the wall.
6. Use finishing nails to secure the molding in place.
7. Repeat the process for any additional corners.
When it comes to installing trim molding, an “outside corner” refers to a corner that protrudes into a room, such as the edge of a chimney or cabinet. Cutting an outside corner in trim molding is similar to cutting an inside corner, where two pieces are cut at 45-degree angles to form a 90-degree angle. The main difference is that the 45-degree cuts for an outside corner are in the opposite direction compared to those for an inside corner.
Step 1
Using a measuring tape, measure from the outer edge of the corner along the wall to the end. Mark this measurement on a piece of trim molding using a pencil.
Step 2
Place the trim molding on a miter saw in the position it will be installed. Position the first end of the molding under the blade.
Step 3
Adjust the blade to a 45-degree angle pointing away from the section of trim you measured. Activate the saw and bring it down through the wood.
Step 4
Measure from the same outside corner along the other wall. Repeat the process by marking and mitering the trim with a 45-degree angle that points away from the measured section of the trim.
Step 5
Cut the opposite ends of each piece of trim based on the situation at the other end of the wall. If it ends on an outside corner, miter it so it points away from the trim. If it ends at an inside corner, miter it so it points towards the trim. If it ends flush against a wall, cut it straight across.
Step 6
Align the two pieces of trim on the wall, with the outside miter cuts meeting at the outside corner. Use a trim nailer to secure them by shooting nails every foot or so along the top and bottom edges of both pieces.
