The thought of cutting corners on molding may seem like an oxymoron to some. After all, molding is typically used to create clean, crisp lines and angles. However, there are times when it is necessary to cut corners on molding, such as when you are working with a curved wall or when you need to create a mitered corner. This guide will show you how to cut corners on molding in a way that is both accurate and professional-looking.
Miters are everywhere. Every time the inside or outside corner of a wall is finished with molding, two pieces of molding must be joined at an angle of 45 degrees. Corners are not always perfect 90 degrees, and walls are not always straight. It is possible to make small adjustments to a miter to account for these discrepancies. You can use a miter saw and a miter box to cut miters. You can also use a power miter saw, but it is important to make sure that the saw is properly calibrated so that the cuts are accurate.
No matter which method you choose, it is important to take the time to make sure that the cuts are as accurate as possible. The better the cuts, the better the miters will look when they are joined together. Additionally, it is important to use the appropriate type of molding for the job. Some moldings are better suited for mitering than others. If you are not sure which type of molding to use, consult with a professional.
Assess the Molding’s Condition
Before attempting to cut corners on molding, it is crucial to thoroughly assess its condition. Proper evaluation ensures that the molding is suitable for mitering and prevents potential issues during the process.
1. Inspect the Molding’s Profile and Material
| Molding Profile | Considerations |
|---|---|
| Simple profiles (e.g., crown, base, casing) | Generally suitable for mitering. |
| Complex profiles (e.g., intricate moldings with multiple curves) | May require special tools or techniques for accurate miters. |
| Material | Considerations |
| Softwood (e.g., pine, fir) | Easy to cut, but prone to chipping and splintering. |
| Hardwood (e.g., oak, mahogany) | More challenging to cut, but less likely to chip or splinter. |
| Laminates (e.g., MDF) | Can be brittle, requiring careful cutting to avoid damage. |
Determine the Location of Studs
Identify Studs Using a Stud Finder
Utilize a stud finder, an electronic device that detects changes in density within walls, to locate the studs. Gently glide the stud finder along the wall surface, listening for an audible signal indicating the presence of a stud. Mark the center of each identified stud with a pencil or marker.
Measure the Distance Between Studs
Determine the distance between studs by measuring the distance between the centers of the marked studs. Common distances range from 16 to 24 inches on center (OC), meaning the centers of the studs are 16 to 24 inches apart.
Use a Magnetic Stud Finder (Optional)
If you encounter difficulties with an electronic stud finder, consider using a magnetic stud finder. This type of stud finder utilizes a magnet that is attracted to nails or screws used to secure studs. Slowly sweep the magnetic stud finder along the wall surface, feeling for the magnetic pull indicating the presence of studs. Note that magnetic stud finders may not be as reliable as electronic stud finders, especially in walls with multiple layers of drywall.
| Stud Location Method | Advantages | Disadvantages |
|---|---|---|
| Electronic Stud Finder | – Fast and easy to use – Detects studs through multiple layers |
– May give false readings on dense or uneven walls |
| Magnetic Stud Finder | – Works on all types of walls – Inexpensive |
– Not as precise as electronic stud finders – May be difficult to use on walls with multiple layers of drywall |
Measure and Mark the Molding
To accurately cut the molding, it’s crucial to measure and mark it precisely. Here’s a detailed guide on how to do it:
Step 1: Measure the Distance between the Walls
Step 2: Mark the Cut Length on the Molding
Step 3: Determine the Cut Angle
Step 4: Mark the Miter Angle
Cut the Molding with a Miter Saw
Using a miter saw is the most common and precise method for cutting molding. Here’s how to do it step by step:
1. Measure and Mark the Molding
Determine the length and angle of each piece of molding you need. Mark the measurements on the molding using a pencil and measuring tape.
2. Set Up the Miter Saw
Adjust the saw blade to a 45-degree angle. If you’re cutting inside corners, set the saw to a 45-degree bevel angle; for outside corners, set it to a 45-degree miter angle.
3. Position the Molding
Place the molding against the saw’s fence, ensuring the marked line is aligned with the saw blade. Hold the molding securely with your non-dominant hand.
4. Cut the Molding
Slowly and carefully guide the molding through the saw blade, keeping your fingers well away from the blade. Be patient and avoid rushing the cut for a clean and precise finish.

5. Repeat for Other Pieces
Repeat steps 1-4 for each piece of molding, ensuring that the angles and lengths match.
Secure the Molding to the Wall
Once the molding is cut, it’s time to secure it to the wall. This can be done with either nails or screws, depending on the type of molding and the surface you’re attaching it to. If you’re using nails, choose nails that are long enough to penetrate the molding and into the wall stud. If you’re using screws, choose screws that are long enough to penetrate the molding and into the wall stud twice.
To secure the molding, start by driving a nail or screw into the center of the molding. Then, work your way out towards the ends, driving a nail or screw into the molding every 12-18 inches. Be sure to countersink the nails or screws so that they’re flush with the surface of the molding.
Once the molding is secured to the wall, you can finish it by caulking the seams and painting it. Caulking the seams will help to seal out drafts and moisture, and painting the molding will give it a finished look.
Here are some additional tips for securing the molding to the wall:
- Use a level to make sure that the molding is level before you secure it to the wall.
- Use a nail set to countersink the nails or screws so that they’re flush with the surface of the molding.
- Caulk the seams between the molding and the wall to seal out drafts and moisture.
- Paint the molding to give it a finished look.
Table of Recommended Nail and Screw Sizes for Securing Molding
| Molding Type | Nail Size | Screw Size |
|---|---|---|
| Baseboard | 1-1/2 inch | #8 x 1-1/2 inch |
| Casing | 1-1/4 inch | #6 x 1-1/4 inch |
| Crown | 1-3/4 inch | #8 x 1-3/4 inch |
