How to Shiplap Walls: Complete DIY Guide for Stunning Interior Design
Shiplap walls have transformed from a humble exterior building material into one of today's most beloved interior design elements, gracing homes from cozy farmhouses to sleek modern apartments. This distinctive wooden paneling, characterized by its overlapping horizontal boards and subtle shadow lines, creates an instant sense of warmth and architectural interest that few other wall treatments can match. Whether you're dreaming of a rustic accent wall in your living room or planning to embrace the full farmhouse aesthetic throughout your home, installing shiplap yourself is not only achievable but surprisingly rewarding. In this comprehensive guide, you'll discover everything from selecting the right materials and tools to mastering professional installation techniques, plus design inspiration to help you create a space that reflects your personal style.
What is Shiplap?
Shiplap refers to a type of wooden board traditionally used in exterior construction, where each plank features a rabbet cut along the top and bottom edges. This clever design allows the boards to overlap slightly, creating a tight seal that was originally intended to keep weather out of ships and barns—hence the name "shiplap."
Modern shiplap paneling maintains this classic overlapping profile but has evolved significantly from its utilitarian roots. Today's interior shiplap often uses tongue-and-groove joints or simple butt joints with spacing between boards to create the signature shadow lines that add depth and texture to walls.
Traditional vs. Modern Shiplap:
- Traditional shiplap features true rabbet joints with tight overlaps
- Modern decorative shiplap may use spacing between boards for visual effect
- Contemporary versions come pre-primed or finished for easier installation
- Some modern options use MDF or engineered materials instead of solid wood
Pros of Using Shiplap:
- Adds instant character and texture to any room
- Relatively affordable compared to other wall treatments
- Can hide imperfections in existing walls
- Timeless appeal that works with multiple design styles
- DIY-friendly installation process
Cons to Consider:
- Can make small rooms feel smaller if overused
- Requires regular maintenance in high-moisture areas
- Horizontal lines may show dust accumulation
- May date your home if trends shift dramatically
Tools and Materials You'll Need
Success with any shiplap project starts with having the right tools and materials. Here's your complete shopping list:
Essential Tools:
- Nail gun (18-gauge brad nailer recommended) or hammer
- Level (4-foot minimum, 6-foot preferred)
- Measuring tape
- Circular saw or miter saw
- Stud finder
- Pencil for marking
- Chalk line for long walls
- Safety glasses and ear protection
- Caulk gun
- Spacers (nickels work perfectly for 1/8-inch gaps)
Materials:
- Shiplap boards (see material options below)
- 2-inch finishing nails or 1.25-inch brad nails
- Wood filler
- Sandpaper (120 and 220 grit)
- Primer and paint or wood stain
- Caulk for seams and corners
- Drop cloths for floor protection
Shiplap Board Options:
- Pine: Traditional choice, affordable, easy to work with, takes paint and stain well
- MDF (Medium Density Fiberboard): Smooth finish, consistent quality, budget-friendly, but not suitable for humid areas
- Plywood: More expensive but extremely durable, good for high-traffic areas
- Pre-finished options: Higher upfront cost but saves time on painting
Planning Your Shiplap Wall Project
Proper planning makes the difference between a professional-looking result and a frustrating DIY disaster. Start by selecting the right location for maximum impact.
Choosing Your Wall: The most effective shiplap installations often focus on creating an accent wall rather than covering entire rooms. Consider walls behind beds, sofas, or dining areas where the texture will be most appreciated. Avoid walls with numerous obstacles like light switches, outlets, or built-in furniture that will require complex cutting.
Measuring and Calculating Materials: Measure your wall's width and height, then multiply to find square footage. Add 10-15% extra material for mistakes and future repairs. For example, a 12-foot by 8-foot wall equals 96 square feet, so order 110 square feet of shiplap.
Wall Preparation Steps:
- Remove all wall decorations and switch plates
- Clean the wall surface thoroughly
- Fill any holes or cracks with spackle
- Prime the wall if you're painting the shiplap a light color
- Use a stud finder to locate and mark all wall studs—you'll need these for secure nailing
Horizontal vs. Vertical Installation: Horizontal shiplap is traditional and makes rooms appear wider, while vertical installation can make ceilings seem higher. Horizontal installation is generally easier for beginners since it requires fewer cuts around obstacles.
Step-by-Step Guide: How to Shiplap Walls
Step 1: Prepare and Cut Boards
Start by acclimating your shiplap boards to your home's humidity for at least 48 hours before installation. This prevents warping after installation.
Measure each board carefully before cutting. For walls longer than your board length, plan your joints to fall on wall studs for the strongest connection. Stagger joints between rows so they don't line up vertically—this creates a more natural appearance.
Step 2: Mark and Level Your Starting Line
This step is crucial for professional results. If you're installing horizontal shiplap, start from the bottom and work up. Use your level to draw a perfectly straight line across the wall where your first board will go. Even if your floor isn't level, this line should be—you can hide any gaps at the bottom with baseboard trim later.
Step 3: Install the First Board
Position your first board along your level line and secure it with finishing nails every 16 inches, hitting wall studs when possible. This bottom board bears the weight of all boards above it, so don't skimp on fasteners.
If you're creating gaps between boards for a more modern look, place spacers (nickels work perfectly) along the top edge before installing the next board.
Step 4: Continue with Proper Alignment
Install each subsequent board, checking for level every few rows. Small adjustments are easier to make early than trying to correct major problems later. Use your spacers consistently to maintain even gaps between boards.
Step 5: Nail and Secure Boards
For hidden fastening, nail through the tongue of tongue-and-groove shiplap or along the top edge where the next board will cover the nails. For visible nailing, use a nail set to countersink nails slightly below the surface—you'll fill these holes with wood filler later.
Step 6: Finishing Touches
Once all boards are installed, fill nail holes with wood filler and let dry completely. Sand smooth with 120-grit sandpaper, then 220-grit for a perfect finish. Caulk all seams where shiplap meets trim, ceilings, or corners. Finally, apply primer and paint or your chosen stain finish.
Design and Styling Ideas
Creating the Perfect Shiplap Accent Wall: Focus on walls that naturally draw the eye—behind headboards, sofas, or dining tables. In living rooms, consider the wall where your TV or fireplace is mounted. The texture and visual interest of shiplap makes these focal points even more dramatic.
White Painted Shiplap: Classic white shiplap remains the most popular choice for good reason. It brightens spaces, works with any color scheme, and provides that fresh, clean farmhouse aesthetic. Use a semi-gloss or satin finish for easier cleaning.
Dark and Stained Options: For a more sophisticated look, consider dark-painted shiplap in navy, charcoal, or black. Natural wood stains in rich walnut or cherry tones create warmth and work beautifully in bedrooms or dining rooms.
Mixing Textures: Combine shiplap with other materials for added visual interest. Pair white shiplap with exposed brick for industrial charm, or use it alongside stone veneer for a rustic cabin feel. Even combining shiplap with regular painted walls creates nice contrast.
Common Mistakes to Avoid
Uneven Spacing: Inconsistent gaps between boards immediately telegraph amateur installation. Use consistent spacers throughout the project.
Poor Wall Preparation: Skipping cleaning, priming, or stud-marking steps leads to problems later. Shiplap installed over dirty or unprepared surfaces won't adhere properly and may warp.
Wrong Materials for the Space: Using MDF shiplap in bathrooms or other high-moisture areas leads to swelling and damage. Choose solid wood or moisture-resistant options for these locations.
Rushing the Finish Work: The difference between DIY-looking and professional-quality results often comes down to properly filling nail holes, caulking seams, and applying quality paint or stain.
Cost and Time Considerations
Budget Breakdown:
- Pine shiplap: $2-4 per square foot
- MDF shiplap: $1.50-3 per square foot
- Pre-finished options: $4-8 per square foot
- Tools and supplies (if you don't own them): $150-300
- Professional installation: $8-15 per square foot including materials
DIY Project Timeline:
- Planning and measuring: 2-3 hours
- Wall preparation: 3-4 hours
- Installation: 6-12 hours depending on wall size
- Finishing (filling, sanding, painting): 4-6 hours plus drying time
Most DIYers can complete a typical accent wall over a weekend, though allowing extra time for the finishing process ensures better results.
Maintenance and Care Tips
Choosing Durable Finishes: Semi-gloss or satin paint finishes resist moisture and clean more easily than flat paint. For stained shiplap, apply a clear polyurethane topcoat for protection.
Cleaning Methods: Regular dusting with a microfiber cloth prevents buildup in the shadow lines between boards. For deeper cleaning, use a slightly damp cloth with mild soap, working in the direction of the wood grain.
Repairing Minor Damage: Small dents can often be raised with a damp cloth and iron—the steam swells the wood fibers. For deeper gouges, use matching wood filler, sand smooth when dry, and touch up with paint or stain.
Conclusion
Installing DIY shiplap walls transforms ordinary rooms into spaces with genuine character and warmth. The combination of natural wood texture, interesting shadow lines, and timeless appeal makes shiplap an investment in your home's beauty and value. While the project requires patience and attention to detail, the techniques are straightforward enough for most homeowners to master.
The key to success lies in careful planning, proper preparation, and taking time with the finishing details that separate amateur work from professional results.
