Embracing the farmhouse aesthetic? A horizontal shiplap half wall is a stunning way to add texture, warmth, and character to your space. This versatile accent wall can transform living rooms, kitchens, or bathrooms, creating a striking focal point. Here's a comprehensive, step-by-step guide to help you achieve this look, complete with expert tips and tricks.
Gather Your Tools and Materials
Before you dive into the installation process, ensure you have all the necessary tools and materials. Here's a list to help you get started:
- Plywood or engineered wood planks (ensure they're shiplap-style with grooves and tongues)
- Circular saw or miter saw
- Jigsaw
- Hammer or nail gun
- Finishing nails (1-1/4" or 1-1/2")
- Level
- Tape measure
- Pencil
- Sandpaper (120-grit)
- Wood filler
- Primer and paint (optional)
Plan Your Shiplap Half Wall
Before you start cutting and nailing, plan your half wall's layout. Measure the wall's height and width, then determine the desired height of your half wall. Common heights range from 36" to 48". Mark the top and bottom of your half wall using a level and pencil.

Calculate Plank Widths
Measure the width of your wall and subtract the width of your planks' grooves. This will give you the maximum width of your planks. For example, if your wall is 96" wide and your planks have a 1/4" groove, your maximum plank width would be 95-3/4".
Prepare Your Planks
Using your circular saw or miter saw, cut your planks to the desired width. Sand any rough edges or surfaces, and fill any holes with wood filler. Allow the filler to dry, then sand it smooth. If you plan to paint your shiplap, apply a coat of primer to seal the wood and help paint adhere.
Install the Bottom Plank
Starting at the bottom of your half wall, install the first plank. Use a level to ensure it's straight, then secure it to the wall using finishing nails. If your wall is not perfectly level, you may need to shim the plank to achieve a straight line.

Install Subsequent Planks
Install the remaining planks, working your way up the wall. Use the tongue-and-groove system to connect each plank to the one below it. Ensure each plank is level and flush with the one below it. Use a scrap piece of wood as a spacer between planks to maintain consistent gaps.
Finishing Touches
Once all your planks are installed, fill any nail holes with wood filler. Allow the filler to dry, then sand it smooth. If you primed your planks, apply a coat of paint in your desired color. If you're leaving your shiplap natural, apply a clear sealant to protect the wood.
Add Trim (Optional)
For a polished look, add trim around the edges of your half wall. This can include baseboard, crown molding, or simple trim pieces. Paint or stain the trim to match your wall and planks.
Enjoy Your New Shiplap Half Wall
