Dark Black Wood Shiplap Siding Boards for Interior

Dark Black Wood Shiplap Siding Boards for Interior and Exterior Walls

Classic Shiplap Profile. Deep Black Stain. Bold, Dramatic, Ready to Install.

Make a statement with our Dark Black Wood Shiplap Siding Boards. Crafted from solid fir and finished with a deep, rich black stain, these boards bring a bold, contemporary edge to the classic shiplap profile. The dark finish transforms the familiar horizontal-board look into something dramatically modern — the kind of wall that commands a room and reads as designed rather than decorated. Against white trim, light walls, and natural materials like stone or concrete, Dark Black shiplap creates a striking, high-contrast effect. Against darker surroundings, it adds depth and dimension without competing for attention. The interlocking shiplap profile keeps installation clean and the result seamless, with a subtle shadow line between each row that adds texture without breaking the bold, unified look of the dark finish.

Available in 94" length with 6 boards per box covering 21.05 sq ft. Install with adhesive, nails, or screws. For exterior use, a UV/weather-resistant polyurethane sealer is recommended.

Why Dark Black

Black is the most decisive finish in the shiplap lineup. There is no ambiguity about what a Dark Black shiplap wall is doing — it is a focal point, a statement, and a design decision that defines the entire room. The deep stain enhances the natural grain of the fir beneath, so the surface is rich and textured rather than flat, and the shiplap profile adds a geometric rhythm that keeps the wall visually interesting up close and from a distance. Used on a single feature wall, Dark Black shiplap creates a bold contrast that makes everything in front of it pop. Used throughout a room, it creates a dramatic, enveloping environment that reads as contemporary, industrial, or refined depending on the surrounding materials. This is the finish for spaces where a white or neutral wall simply is not enough.

• Feature walls and accent walls — the boldest focal point in the lineup
• Home offices — dramatic, focused, and commanding
• Dining rooms and bar areas — moody, sophisticated backdrop
• Bathrooms — high-contrast, spa-like drama
• Exterior facades — bold curb appeal, especially against light siding or trim
• Commercial interiors — restaurants, retail, hotels — a striking, memorable finish
• Modern, industrial, and Scandinavian interiors — a natural fit for dark, minimal design

How to Install Dark Black Wood Shiplap Siding Boards

Installation is straightforward and can be completed by most DIY homeowners and contractors in a few hours. For exterior applications, apply sealer before installation.

Step 1: Prepare the Surface

The wall must be clean, dry, and structurally sound. For interior walls, fill any holes or cracks and let patched areas dry fully. For exterior installations, ensure proper moisture barriers and framing are in place before beginning.

Step 2: Apply Sealer (Exterior Use)

For exterior installations, apply a UV/weather-resistant polyurethane sealer to all surfaces of each board — face, back, and edges — before mounting. Allow to fully cure per the sealer manufacturer's instructions.

Step 3: Measure and Plan Layout

Measure the wall area to calculate how many boxes you need, adding 10% for cuts and waste. Mark a level starting line at the bottom of the installation area to keep all rows level from the first board up.

Step 4: Dry Fit

Before fastening, lay out the boards against the wall to confirm your layout and identify where cuts are needed around windows, doors, outlets, and corners.

Step 5: Install the First Row

Start at the bottom with the rabbet groove facing up. Apply construction adhesive to the back, or fasten with nails or screws into wall studs. Use a level to confirm the first row is perfectly level — all subsequent rows depend on it.

Step 6: Continue Row by Row

Slide each subsequent board's tongue into the groove of the board below, creating the interlocking shiplap joint. Fasten each row and check level periodically as you work up the wall.

Step 7: Cut to Fit

At wall edges, corners, windows, doors, and outlets, trim boards with a miter saw, circular saw, or jigsaw. For exterior installations, seal all cut edges before mounting. Touch up any cut edges with matching black stain to maintain the finished look.

Step 8: Final Inspection

Confirm all boards are firmly attached, level, and aligned. The pre-finished Dark Black surface requires no additional staining or painting — the installation is complete.

Frequently Asked Questions

Q: What does Dark Black look like?

A: Dark Black is a deep, rich black stain that enhances the natural grain of the fir wood beneath. The surface has texture and depth — it reads as genuine wood rather than painted drywall. Order a 6" swatch to see it in your actual space under your lighting before committing to full boxes.

Q: Is this panel pre-finished?

A: Yes — these boards arrive pre-finished in Dark Black stain and are ready to install straight from the box. No staining or painting required for interior use.

Q: Can these be used on exterior walls?

A: Yes — suitable for interior and exterior use. For exterior applications, apply a UV/weather-resistant polyurethane sealer to all surfaces including edges before installation.

Q: What is shiplap?

A: Shiplap is a type of wooden board milled with a rabbet (notch) cut into the top and bottom edges. The boards interlock, creating tight, seamless rows with a consistent shadow line between each course. Originally used as exterior siding, shiplap has become one of the most popular interior wall treatments for modern, industrial, and contemporary designs.

Q: How is this installed?

A: These boards can be installed with construction adhesive, nails, or screws. For most interior walls, face-nailing into studs is the most secure method. For exterior use, exterior-grade fasteners are required.

Q: Can these be painted?

A: Yes — lightly sand the surface and apply a primer coat before your topcoat for best adhesion.

Q: Can these be installed on ceilings?

A: Yes. Fasten with screws directly into ceiling joists for a secure overhead installation.

Q: Do these panels help with sound?

A: These are cladding boards, not acoustic panels. The wood surface helps diffuse sound reflections compared to a flat hard wall. For dedicated acoustic performance, see our Acoustic Wall Panel collection.

Q: Is free shipping included?

A: Yes — free shipping within the contiguous United States.

Q: Do you have a showroom?

A: Yes — 10926 Woodside Ave Suite A, Santee, CA 92071. Monday–Friday, 8am–4pm.
