1. Measure and mark: Measure the baseboard length for each wall section leading to the outside corner and mark the cut location. 2. Set the miter saw: Set your miter saw to a 45-degree angle for a standard 90-degree corner. 3. Position the baseboard: Place the baseboard on the saw, ensuring the bottom face is against the fence and the back is against the table. 4. Make the cut: Cut through the marked line. 5. Repeat for the other side: Cut the adjoining baseboard piece at the opposite 45-degree angle.

The process for cutting trim outside corners is similar to cutting baseboard outside corners: 1. Measure and mark: Measure and mark the trim pieces. 2. Set the miter saw: Set the miter saw to 45 degrees. 3. Position the trim: Place the trim on the saw, ensuring proper alignment. 4. Make the cut: Cut through the marked line. 5. Repeat for the other side: Cut the adjoining trim piece at the opposite 45-degree angle.

Mitering outside corners involves cutting the ends of two adjoining pieces at an angle so they fit together seamlessly. The most common angle for mitering outside corners is 45 degrees, resulting in a 90-degree corner when joined.

1. Measure and mark: Measure the molding length for each side of the corner and mark the cut location. 2. Set the miter saw: Set the miter saw to 45 degrees. 3. Position the molding: Place the molding on the saw, ensuring proper alignment. 4. Make the cut: Cut through the marked line. 5. Repeat for the other side: Cut the adjoining molding piece at the opposite 45-degree angle.

While the term "moulding" often refers to decorative elements, the process for cutting outside corners on functional moulding (like baseboards or trim) is the same as cutting any other outside corner. Here's a breakdown: 1. Precise Measurement: Accurately measure the length of moulding needed for each wall section leading to the outside corner. Mark the moulding precisely where the cut needs to be made. 2. Miter Saw Setup: For a standard 90-degree corner, adjust your miter saw to a 45-degree angle. Double-check the angle setting for accuracy. 3. Secure Positioning: Place the moulding on the miter saw table, ensuring the bottom face is firmly against the fence and the back is flush against the table. This prevents shifting during the cut. 4. Execute the Cut: Activate the saw and make a smooth, controlled cut through the marked line on the moulding. 5. Mirror the Cut: For the adjoining piece of moulding, adjust the miter saw to the opposite 45-degree angle and repeat the cutting process. Key Considerations: Coping Technique: For walls that aren't perfectly square, the coping method can create a tighter fit. This involves cutting one piece at a 45-degree angle and then carefully shaping the mating piece to match its contours. Dry Fit is Crucial: Before applying any adhesive, always dry-fit the two mitered pieces together to ensure a seamless and gap-free joint. Account for Expansion: In areas with high humidity, slightly undercut the edges of the moulding to allow for expansion and prevent buckling over time.
