Securing the Corners
Once the corner molding has been cut and prepared, there are several ways to secure it in place:
Using Nails
Nails are a simple and effective way to secure corner molding. Use nails that are long enough to penetrate through the molding and into the wall studs by at least 1 inch.
Using Screws
Screws provide a stronger hold than nails, making them a good choice for heavier or more delicate molding. Use screws that are slightly longer than the thickness of the molding.
Using Adhesive
Adhesive can be used to supplement nails or screws, or even as a standalone method for securing corner molding. Apply a bead of adhesive to the back of the molding before pressing it into place.
Using a Corner Clamp
A corner clamp is a specialized tool designed to hold mitered corners together while the adhesive dries. It can be a useful addition for ensuring a tight and secure fit.
Choosing the Right Hardware
The choice of hardware for securing corner molding depends on the weight of the molding, the condition of the walls, and personal preference. The following table provides a summary of the different options:
| Hardware |
Pros |
Cons |
| Nails |
Easy to use, inexpensive |
Can damage molding if not driven properly |
| Screws |
Strong hold, less damage to molding |
More difficult to install, requires pre-drilling |
| Adhesive |
Invisible, no damage to molding |
Can be messy, may not hold heavy molding securely |
| Corner Clamp |
Ensures a tight fit, prevents gaps |
Specialized tool, may not be necessary for all projects |
Filling and Finishing the Joint
Once the molding pieces are cut and fitted, it’s important to fill and finish the joint to create a smooth and professional-looking transition. Here are the steps to do so:
1. Apply Wood Filler
Squeeze a thin bead of wood filler into the joint along the entire length of the molding. Use a putty knife to smooth and shape the filler, ensuring there are no voids or excess material.
2. Sand the Joint
Once the wood filler has dried completely, use fine-grit sandpaper to smooth the surface, removing any ridges or bumps. Sand in the direction of the grain to avoid damaging the wood.
3. Apply Primer
Apply a thin coat of primer to the joint area, including the wood filler. This will help to seal the surface and prevent the wood grain from showing through the paint.
4. Paint the Joint
Use a brush or roller to apply two coats of paint to the joint area in the same color as the surrounding molding. Allow each coat to dry completely before applying the next.
5. Touch Up the Joint
After the paint has dried, inspect the joint for any imperfections. If necessary, apply additional wood filler, sand, prime, and paint again to ensure a flawless finish.
6. Seal the Joint
To protect the joint from moisture and wear, apply a clear caulk or sealant along the length of the joint. This will help to prevent water damage and keep the joint looking its best.
7. Sand and Clean the Surface
If desired, lightly sand the sealed joint with fine-grit sandpaper to smooth out any rough edges. Then, wipe the surface with a clean cloth to remove any dust or debris.
8. Consider Using a Joint Tape
For a stronger and more durable joint, consider using a joint tape or mesh before applying wood filler. This provides additional support and helps to prevent the joint from cracking or breaking over time. A joint tape is a thin, self-adhesive strip of paper or mesh that is applied over the joint before the wood filler. It helps to reinforce the joint and prevents cracking.
| Pros of Using a Joint Tape |
Cons of Using a Joint Tape |
- Strengthens the joint
- Prevents cracking
- Easy to apply
|
- Additional material cost
- May require more sanding to achieve a smooth finish

Tool Selection
For mitering outside corner molding, a miter saw is essential. Ensure you have a sharp blade for clean, precise cuts.
Measuring and Marking
Determine the length of the molding for each side of the corner. Transfer these measurements onto the molding and mark the cut lines carefully.
Adjusting the Angle
Set the miter saw to a 45-degree angle. Ensure the angle is accurate to avoid gaps or overlaps when joining the pieces.
Cutting the First Side
Secure the molding in the miter saw and align the marked cut line with the saw blade. Make a clean, smooth cut by pressing down steadily.
Positioning for the Second Cut
Flip the molding over and place the freshly cut end flush against the fence of the saw. Ensure the molding is well-supported to prevent it from moving.
Cutting the Second Side
Align the second cut line with the saw blade and make another clean cut. The resulting piece should have a perfect 45-degree miter.
Tips for a Perfect Cut
- Use a sharp blade to ensure clean cuts.
- Secure the molding firmly in the saw to prevent movement.
- Double-check the angle setting to ensure accuracy.
- Align the cut line precisely with the saw blade.
- Press down steadily when making the cut.
- Make sure the molding is well-supported when cutting the second side.
- Dry fit the pieces together before installing them to ensure they fit correctly.
- If necessary, use a sanding block to smooth any rough edges.
- Use a brad nailer or wood glue to securely join the pieces.
Coating and Finishing
Once the molding is installed, apply a coat of paint or stain to match the surrounding trim. This will enhance the appearance and protect the wood from damage.
Coping Crown Molding
Coping crown molding involves cutting the molding at an angle to fit around corners. To ensure a precise fit, measure the distance between the walls at the corner and transfer this measurement to the molding. Use a miter saw to cut the molding at the measured angle, then hold the two pieces together and trace the profile of the molding onto the second piece. Cut out the profile using a coping saw, and the two pieces should fit together perfectly.
Installing Outside Corner Molding
Outside corner molding is installed by first measuring and cutting the molding to fit the length of the corner. Apply adhesive to the back of the molding and press it into place, aligning it with the corner. Use a nail gun to secure the molding, driving nails every few inches. Repeat the process for the other molding piece, overlapping the two pieces at the corner. Secure the overlap with nails, and fill any nail holes with wood filler.
Troubleshooting Common Issues
10. Difficulty Coping Crown Molding
If you encounter difficulties coping crown molding, check the following:
10.1. Ensure that you are using a sharp coping saw. A dull saw blade will make it difficult to cut clean, precise lines.
10.2. Make sure that the molding is held securely in place while you are cutting. A loose molding can result in inaccurate cuts.
10.3. Practice coping on scrap pieces of molding before attempting to cut the actual molding. This will help you develop the necessary skills and avoid potential mistakes.
10.4. Use a coping block to guide the coping saw. A coping block can help to ensure that the cuts are accurate and consistent.
10.5. If you are still having difficulty, consult a professional carpenter or woodworker for assistance.
