How to End Beadboard on an Outside Corner

Summary: To end beadboard on an outside corner, measure the depth of the beadboard and cut a piece of plywood to that depth. Make a rabbet on one side of the plywood so it fits snugly into the corner. Mark the positions of the screws on the plywood. Drill holes in the plywood at the mark and screw the plywood into the corner.

9 Methods about How to End Beadboard on an Outside Corner

1. Use a Miter Saw 

You need to cut two pieces of beadboard at a 45-degree angle. Place the first piece of beadboard against the outside corner of the wall and nail it. Next, fit the second piece of beadboard against the first piece and fix it.

2. Caulk the Seam

Use a putty knife to apply paintable caulk along the seam between the beadboard and the wall. Smooth out the caulk with your finger. Allow the caulk to dry for 24 hours before painting over it.

Use a tape measure to determine how much beadboard you will need to cut off at the outside corner. Make a pencil mark on the beadboard at this measurement with a level.

4. Install the Beadboard Planks

Use a saw to cut along the marked line. You can use a hand or power saw for this, although a power saw will make the job go faster. Position the first piece of beadboard at the outside corner, ensuring that the top edge is level with the chalk line. Secure the plank in place using nails or screws

5. Install the Beadboard

Install the beadboard as you would normally, starting at the outside corner and working your way in. Ensure that the beadboard’s last piece fits snugly against the inside corner. You may need a trim router to make a clean, flush fit.

 6. Use a Spackle Knife or Putty Knife to Apply Joint Compound

Wipe away any excess compound with a damp cloth. Next, install a corner bead over the joint compound using nails or screws. Apply joint compound to the corners, and wipe away any excess with a damp cloth. Paint or stain the beadboard as desired.

7. Attach the Panel

Secure the Beadboard to an Outside Corner. Add Trim or Molding for a Finished Look. Then caulk and Paint the Outside Corner beadboard Installation. There are only a few when you reach the end of a wall run and must finish the beadboard. Finally, attach the beadboard panel to the studs using screws or nails.

8. Use Trim

Cut a piece of trim molding to fit snugly between the two parts of the beadboard that meet at the corner. Nail the trim molding in place using finishing nails. Use a putty knife to fill nail holes with wood putty, then sand smooth. Paint or stain the trim molding to match the beadboard.

9. Paint or Stain the Beadboard

After the beadboard is installed, you can either paint or stain it. If you plan to paint the beadboard, use a primer first. This will help the paint adhere better and provide an excellent base color.

If you plan to stain the beadboard, test the stain on a small area first to make sure it’s the color you want. Once you’ve decided on the right color, apply the paint with a brush or rag and let it dry completely. Once the beadboard is installed, you can add any trim or molding to finish the look. You may also want to paint or stain the beadboard to match the rest of your trim work.

Step-by-Step Guideline on How to End Beadboard on an Outside Corner

Step 1: Measure the Length of the Corner Trim Molding

Using a measuring tape, measure the length of the corner trim molding you need. Add an extra few inches to your measurement to allow for mistakes.

Step 2: Cut the Corner Trim Molding

Use a miter, coping, jigsaw, or router to cut the corner trim molding to the desired length. If using a hand saw, make sure to use an excellent tooth blade so that your cuts are as accurate as possible.

Step 3: Attach the Corner Trim Molding

Use a nail gun or screws and screwdriver to attach the corner trim molding to the beadboard paneling. Ensure the Trim is level and flush with the rest of the beadboard.

Finish up by caulking any gaps between the Trim and the beadboard. Allow the caulk to dry completely before painting or staining.

4 Ways to End Beadboard on an Outside Corner

1. Using a Coping Saw

Using a coping saw, ensure the blade is tight in the frame and pointed downwards. Start by cutting along the line at a 45-degree angle, then turn the saw so the blade points upwards and finish the cut. Once you’ve made your cuts, use a chisel to remove any rough edges.

2. Use a Jigsaw

Use a tape measure to find the center of the beadboard panel and mark it with a pencil. Draw a line from the top corner of the beadboard panel to the center mark. This will be your cut line. Clamp the beadboard panel to a work surface. Use a jigsaw or coping saw to cut along the line. Sand the edges of the cut beadboard panel with sandpaper to smooth them out.

3. Use a Router

If you’re using a router, make sure to use a fence, so your cuts are consistent. Start by routing the top edge of the beadboard. Then, route the side of the beadboard that will be visible from the front. Finally, finish up by routing the bottom edge of the beadboard.

If you’re not using a router, you can use a jigsaw or other cutting tool to make the cuts. Just be sure to measure carefully and make straight cuts.

Once you’ve cut the beadboard, apply a coat of paint or sealer to protect it from the elements. And that’s it! You’ve now successfully ended the beadboard on an outside corner.

4. Use a Hand Saw

The first step is to mark your cut line. Use a level to ensure your line is perfectly straight, then use a pencil or chalk to mark your cut line. Next, you’ll need to cut your beadboard. You can use a hand saw for a cleaner cut or a power saw if you’re more comfortable. Just be sure to wear eye and ear protection while you’re cutting.

Once your beadboard is cut, you can install it on your wall. Start at the top corner and work your way down, nailing the beadboard into place as you go. Make sure to use finish nails, so they’re flush with the surface of the beadboard.

Beadboard corners are one of the trickier parts of any beadboard project. But with the right tools and a little patience, you can get clean, professional-looking results.

What Do You Put on the Outside Corner of a House?

The outside corner of a house requires a bit of attention as it is a prime location for wear and tear from the elements. Typically, one would install corner trim, also known as corner boards, to cover and protect the seam where the siding meets. These trim pieces can be made from a variety of building materials, such as vinyl, aluminum, wood, or fiber cement. They give your house a finished look and protect the outside corners from water, wind, and other weather-related damage.

Corner trim also allows for proper sealing and insulation at the corners, protecting them from water, insects, and other undesirable weather conditions. Additionally, the corner trim provides a great opportunity to add a decorative touch to the house design, allowing the homeowner to add personal touches to their home’s overall look and feel.

How Do You Join Beadboard Corners?

Joining beadboard corners is a relatively simple process that can be done with a few basic tools and some attention to detail. Beadboard is a type of paneling commonly used for interior walls, ceilings, and other applications. It often features a tongue-and-groove design that allows the panels to fit together snugly.

To join beadboard corners, begin by measuring the length of each panel that will meet at the corner. Use these measurements to cut two pieces of trim that will fit along the corner and hide the joint between the panels. These pieces can be cut from wood or PVC and should be the same width as the panels themselves.


Always use a level to ensure the top of the beadboard is even. If you have a helper, it will make the process much easier. First, use a saw to cut the board to size and then attach it using finish nails or construction adhesive. Finally, caulk along the seams between boards if you’re ready to paint or stain your beadboard paneling for an updated look on your exterior corner.
