Step-by-Step Guide to Cutting Skirting Boards

Now that you have your tools and materials ready, let’s dive into the step-by-step process of cutting skirting boards.

1. Accurate Measuring is Key

The foundation of a successful skirting board installation lies in accurate measurements. Measure each wall carefully, paying close attention to corners and any irregularities. It’s always better to measure twice and cut once. Remember that inside corners require a different approach than outside corners.

* **Straight Walls:** Measure the length of the wall where the skirting board will be installed. Record these measurements accurately.
* **Inside Corners:** Inside corners are where two walls meet inward. You will need to create a cope joint or a mitered joint. More on this later.
* **Outside Corners:** Outside corners are where two walls meet outward. These require a mitered joint.

2. Understanding Miter Angles

The most common angles you’ll encounter are 45-degree angles for 90-degree corners. However, not all corners are perfectly square. Use a combination square or protractor to determine the exact angle of the corner. Divide the corner angle by two to determine the miter angle for each piece of skirting board. For example, if the corner is 90 degrees, each piece of skirting board will be cut at a 45-degree angle.

* **Perfect 90-Degree Corners:** Divide 90 by 2, resulting in 45 degrees for each piece.
* **Corners Greater than 90 Degrees:** If you measure a corner at 95 degrees, divide that by 2. Each piece would need a 47.5-degree cut.
* **Corners Less than 90 Degrees:** Conversely, if the corner is 85 degrees, each piece requires a 42.5-degree cut.

3. Cutting Inside Corners: Coping vs. Mitering

There are two primary methods for joining skirting boards at inside corners: coping and mitering. While mitering is simpler, coping provides a tighter, more professional-looking joint, especially in corners that aren’t perfectly square.

a. Mitering Inside Corners

Mitering involves cutting both pieces of skirting board at the calculated angle (usually 45 degrees for a 90-degree corner). The two pieces are then joined to form the corner.

* **Set Up:** Set your miter saw to the appropriate angle (e.g., 45 degrees). Ensure the saw is locked securely at the desired angle.
* **First Cut:** Place the first piece of skirting board against the fence of the miter saw. The back of the skirting board should be facing the fence. Make the cut.
* **Second Cut:** Rotate the miter saw to the opposite angle (e.g., -45 degrees). Place the second piece of skirting board against the fence, again with the back facing the fence. Make the cut.
* **Test Fit:** Bring the two pieces together to check the fit. If the corner is not perfectly square, you may need to adjust the angles slightly.

b. Coping Inside Corners

Coping involves mitering one piece of skirting board and then using a coping saw to remove the back portion of the second piece, allowing it to conform perfectly to the shape of the first piece.

* **Miter the First Piece:** Cut the first piece of skirting board at a 45-degree angle (or the appropriate angle based on your corner measurement) as described above.
* **Miter the Second Piece (For Marking):** Cut the second piece of skirting board at the same angle, but in the opposite direction. This mitered cut is only for marking the cope line.
* **Trace the Cope Line:** Place the mitered end of the second piece against the face of the first piece (the piece already installed). Trace the profile of the mitered cut onto the second piece. This line is your cope line.
* **Coping the Second Piece:** Use a coping saw to carefully cut along the cope line. Angle the saw slightly backward, removing the material behind the face of the skirting board. This creates a slight back-cut that allows the piece to fit snugly against the first piece, even if the corner isn’t perfectly square.
* **Fine-Tune the Fit:** Use sandpaper or a utility knife to fine-tune the fit of the cope joint. The goal is to create a seamless transition between the two pieces.

4. Cutting Outside Corners

Cutting outside corners requires mitering both pieces of skirting board. The process is similar to mitering inside corners, but the angles are oriented differently.

* **Set Up:** Set your miter saw to the appropriate angle (e.g., 45 degrees). Ensure the saw is locked securely at the desired angle.
* **First Cut:** Place the first piece of skirting board against the fence of the miter saw. The *front* of the skirting board should be facing the fence for outside corner cuts. Make the cut.
* **Second Cut:** Rotate the miter saw to the opposite angle (e.g., -45 degrees). Place the second piece of skirting board against the fence, again with the *front* facing the fence. Make the cut.
* **Test Fit:** Bring the two pieces together to check the fit. Adjust the angles slightly if necessary.

5. Cutting Straight Lengths

Cutting straight lengths is the simplest of all. Simply measure the required length and make a straight cut using your miter saw.

* **Measure and Mark:** Measure the wall and mark the length on the skirting board using a pencil.
* **Set Up:** Set your miter saw to 0 degrees for a straight cut.
* **Make the Cut:** Align the marked line with the blade and make the cut. Ensure the skirting board is held securely in place during the cut.

6. Dealing with Uneven Walls and Floors

In older homes, walls and floors are often uneven. This can make installing skirting boards challenging. Here are some tips for dealing with these issues:

* **Scribing:** If the floor is uneven, you can scribe the skirting board to match the contour of the floor. Place the skirting board against the wall and use a compass to trace the floor’s outline onto the back of the skirting board. Then, use a jigsaw to cut along the line.
* **Using Shims:** For gaps between the skirting board and the wall, use shims to fill the space. Shims are thin pieces of wood that can be inserted behind the skirting board to provide support and create a flush surface. After installation, you can caulk the gaps to conceal the shims.
* **Flexible Caulk:** Use flexible caulk to fill any small gaps along the top edge of the skirting board where it meets the wall. This will create a clean, finished look and prevent drafts.

7. Safety First!

Working with power tools can be dangerous if proper safety precautions are not followed. Always wear safety glasses and ear protection when using a miter saw. Keep your hands away from the blade and ensure the skirting board is securely clamped in place. Never rush the job, and take breaks when needed.

Tips for Achieving Professional Results

Here are some additional tips to help you achieve professional-looking results:

* **Sharp Blades:** Use a sharp blade on your miter saw. A dull blade can cause splintering and inaccurate cuts. Replace the blade regularly to maintain optimal performance.
* **Practice Cuts:** Before cutting your actual skirting boards, practice on scrap pieces of wood. This will help you get a feel for the saw and ensure your cuts are accurate.
* **Consistent Pressure:** Apply consistent pressure when cutting. Avoid pushing or pulling the skirting board too hard, as this can cause the saw to bind or kick back.
* **Smooth Edges:** After cutting, use sandpaper to smooth any rough edges. This will prevent splinters and create a more polished look.
* **Fill Gaps:** Use wood filler or caulk to fill any small gaps or imperfections. Sand the filler smooth and paint or stain to match the skirting board.
* **Proper Installation:** Use construction adhesive and nails to securely attach the skirting boards to the wall. Locate studs using a stud finder for maximum holding power.
* **Consistent Finish:** Apply a consistent finish to the skirting boards. Whether you choose to paint, stain, or varnish, ensure the finish is even and smooth.

Installing the Skirting Boards

Now that you’ve cut all your skirting boards, it’s time to install them. This process involves adhering the boards to the wall securely.

1. **Locate Wall Studs:** Use a stud finder to mark the location of the wall studs. This will provide a secure point for nailing the skirting boards.
2. **Apply Adhesive:** Apply a bead of construction adhesive to the back of the skirting board. Focus on areas that will make contact with the wall.
3. **Position and Press:** Position the skirting board against the wall, aligning it with your desired placement. Press firmly along the entire length to ensure good contact with the adhesive.
4. **Nail into Studs:** Use a nail gun or hammer and nails to secure the skirting board to the wall studs. Space the nails evenly, about 12-16 inches apart.
5. **Check for Level:** Use a level to ensure the skirting board is straight, particularly on longer runs. Make adjustments as needed before the adhesive sets.
6. **Clean Excess Adhesive:** Wipe away any excess adhesive that squeezes out from behind the skirting board.
7. **Repeat:** Repeat steps 2-6 for all remaining sections of skirting board.

Finishing Touches

After installing the skirting boards, there are a few finishing touches to complete the project and create a professional look.

1. **Fill Nail Holes:** Use wood filler to fill the nail holes. Allow the filler to dry completely.
2. **Sand Smooth:** Sand the filled nail holes smooth with fine-grit sandpaper.
3. **Caulk the Top Edge:** Apply a bead of paintable caulk along the top edge of the skirting board where it meets the wall. This will seal any gaps and create a clean, finished look.
4. **Paint or Stain:** Paint or stain the skirting boards to match your desired color or finish. Apply multiple coats for a durable and even finish.

Troubleshooting Common Problems

Even with careful planning and execution, you may encounter some common problems during the skirting board installation process. Here are some solutions:

* **Gaps Between Skirting Board and Wall:** Use shims to fill the gaps and then caulk the edges.
* **Uneven Corners:** Adjust the miter angles slightly or use a coping saw to create a tighter fit.
* **Splintering Wood:** Use a sharp blade and make slow, controlled cuts.
* **Skirting Board Not Staying Attached:** Ensure you are using enough adhesive and nails. Locate and nail into wall studs.
