How to cut coving external corners
Coving, also known as crown molding, is a decorative trim that is used to add a finishing touch to the corners of a room. It not only enhances the appearance of the space, but it also helps to create a smooth transition between the wall and ceiling. One of the most challenging aspects of installing coving is cutting the external corners. This requires precision and careful measurements to ensure a perfect fit.
To cut coving for external corners, you will need a few tools, including a coving mitre box, a coping saw, and a pencil. Before cutting, it is essential to mark the correct angle on the coving using a pencil. This will serve as a guide when using the coving mitre box to make the cut. Make sure to hold the coving securely in place inside the mitre box and cut along the marked line with a coping saw. It is crucial to take your time and make precise, controlled cuts to achieve the desired result.
When cutting coving for external corners, it is important to remember that the angle may not always be a perfect 90 degrees. It is common for walls to have some degree of deviation from a right angle, so it is essential to measure and adjust accordingly. By using a protractor or an adjustable bevel, you can determine the exact angle of the corner and make the necessary adjustments to cut the coving correctly.
Cutting coving for external corners can be a challenging task, but with the right tools and techniques, it is possible to achieve a professional finish. Remember to measure, mark, and cut with precision, and take your time to ensure a perfect fit. By following these steps, you will be able to create visually appealing corners that add elegance and character to any room.
Best techniques for cutting coving external corners
Cutting coving for external corners can be a bit challenging, but with the right techniques, you can achieve a professional and seamless finish. Here are some tips to help you cut coving for external corners:
1. Measure and mark:
Before cutting the coving, measure the length of the wall and mark the appropriate length on the coving. Use a straightedge and a pencil to ensure an accurate measurement and mark.
2. Cut at a 45-degree angle:
To create a neat corner, you need to cut the coving at a 45-degree angle. Use a miter box or a coving mitre tool to make precise and consistent angle cuts. Hold the coving firmly in place and saw through the marked line with a tenon saw.
3. Fit the cut coving:
After cutting the coving, dry fit it to ensure the corner fits properly. If there are any gaps or irregularities, you may need to make additional adjustments to the angle or length of the cut.
4. Seal the coving joints:
Once you are satisfied with the fit, it’s important to seal the joints properly. Apply a thin layer of flexible filler to the joints and smooth it out with a filling knife or a wet finger. Allow the filler to dry completely before continuing with the installation.
5. Secure the coving:
Using the appropriate adhesive, fix the coving to the wall by applying the adhesive to the back of the coving. Press the coving firmly against the wall, making sure it aligns perfectly with the corner. Use pins or temporary braces to hold the coving in place until the adhesive dries.
6. Sand and paint:
Once the adhesive has dried, gently sand any rough edges or imperfections on the coving. Wipe away any dust and apply a coat of primer followed by your chosen paint or finish.
By following these techniques, you can achieve a professional and seamless finish on your coving external corners. Remember to take your time and double-check your measurements and cuts for the best results.
Measure and mark the coving
Before cutting the coving for external corners, it is important to measure and mark the coving accurately to ensure a precise fit.
1. Find the angle
Use a protractor or an angle finder to measure the angle of the external corner. Place the tool against the wall and ceiling, aligning it with the corner. Read the measurement shown on the tool to determine the angle.
2. Transfer the angle
Once you have determined the angle, transfer it onto the coving. Use a pencil or a marker to mark the angle on the back of the coving.
Note: Make sure to mark both ends of the coving to ensure a symmetrical fit.
Alternatively, you can use a template or a miter box to transfer the angle onto the coving.
Ensure that the markings are clear, visible, and accurate. Double-check the measurements before proceeding to cut the coving.
Remember to wear appropriate safety gear, such as protective gloves and goggles, while measuring and marking the coving.
Use a backsaw or coping saw for curved corners
When it comes to cutting coving for curved external corners, using a backsaw or coping saw is the best approach. The shape and angle of the curved corner makes it impossible to use a regular miter saw or a miter box, so a finer-cutting tool is required.
Here are the steps to cut coving for curved corners using a backsaw or coping saw:
- Measure the length of the coving required for the curved corner.
- Using a pencil, mark the top section of the coving with the measured length.
- Carefully secure the coving in a vise to keep it stable while cutting.
- Hold the coping saw or backsaw at a slight angle to match the curvature of the corner and start cutting.
- Move the saw slowly and steadily along the marked line, making sure to follow the curve of the corner.
- Regularly check the fit of the cut coving against the curved corner to ensure a precise fit.
- Once you’re satisfied with the fit, you can install the cut coving onto the curved corner using the appropriate adhesive or fixing method.
Tips:
- Take your time and be patient while cutting the coving for a curved corner, as it requires more precision than cutting for straight corners.
- Ensure that the saw is sharp and in good condition, as a dull or damaged tool can lead to an uneven and rough cut.
- Practice cutting on a spare piece of coving or scrap wood before attempting to cut the final piece for the actual curved corner.
By using a backsaw or coping saw for cutting coving for curved corners, you’ll be able to achieve a professional and precise finish that complements the overall aesthetic of your space.
Tips for achieving seamless coving external corners
Installing coving can add a touch of elegance to any room, but achieving seamless external corners can be a bit tricky. Here are some tips to help you achieve professional results:
1. Careful measuring and cutting
The key to achieving a seamless external corner is precise measuring and cutting of the coving. Use a tape measure to accurately measure the length of each section, ensuring they fit together snugly. When cutting, be precise and eliminate any gaps between the sections.
2. Make use of corner pieces
In order to achieve a seamless corner, consider using corner pieces made specifically for coving. These pieces are designed to fit perfectly and provide a seamless transition between the sections. They can simplify the installation process and ensure a smooth finish.
3. Use a coping saw for complex corners
If you have complex corners that cannot be easily accommodated with standard cuts, a coping saw can be your best friend. Instead of an angled cut, use a coping saw to create a profile that perfectly matches the shape of the corner. This will result in a seamless join and a professional appearance.
4. Use a good quality adhesive
To ensure that your coving stays in place and the corners remain seamless, it’s important to use a high-quality adhesive. Choose an adhesive specifically designed for coving, and follow the manufacturer’s instructions for application. This will provide a strong bond and ensure a lasting finish.
5. Sand and fill imperfections
Even with careful installation, there may still be some imperfections in the corners. To achieve a seamless look, use a sanding block to smooth out any rough edges or uneven areas. Fill any gaps or cracks with a suitable filler, then sand again for a perfect finish.

Sand and smooth the edges of the coving
After the coving has been cut and installed on the external corners, it’s important to sand and smooth the edges to ensure a seamless appearance. This process will not only remove any roughness or imperfections but also help to blend the coving with the surrounding walls.
To sand the edges of the coving, you will need sandpaper with a fine grit. Start by folding the sandpaper into a small square or using a sanding block for better control. Gently rub the sandpaper along the cut edges, using smooth back-and-forth motions. Be careful not to apply too much pressure or sand too aggressively, as this may damage the coving.
Pay special attention to any rough or sharp areas on the edges. Aim to smoothen them out completely. It’s also a good idea to lightly sand the adjacent wall surface to ensure a seamless transition.
Once you are satisfied with the smoothness of the edges, wipe away any dust or debris with a clean, damp cloth. This will help to ensure a clean finish when you come to paint or finish the coving.
Tips:
- Test the sandpaper on a small, inconspicuous area of the coving first to make sure it doesn’t cause any damage.
- Wear a dust mask to protect your lungs from any airborne particles while sanding.
