What to Install Shiplap With: A Homeowner's Guide
Discover what to install shiplap with, from fasteners to adhesive. A practical homeowner guide on materials, methods, and finishing for durable, stylish walls.
Shiplap should be installed with corrosion-resistant fasteners and adhesive for best long-term stability. Use finish nails or a nail gun paired with construction adhesive for an extra hold. Ensure a clean wall, locate studs, and maintain a small expansion gap between boards to accommodate seasonal movement. Optionally, prime and seal boards for moisture-prone areas.
What to install shiplap with and why it matters
Shiplap is a timeless wall treatment that creates clean, horizontal lines and subtle shadows. It can dramatically change a room’s character with relatively simple installation. This guide explains what to install shiplap with, from fasteners to sealants, so homeowners and DIY enthusiasts can approach the project confidently. According to Install Manual, selecting the right combination of hardware and materials reduces issues like warping and gaps, delivering a durable finish. The approach you choose—fasteners alone, adhesive alone, or a hybrid—depends on wall condition, board thickness, and your preferred look. In practice, most projects benefit from a hybrid method: mechanical fasteners for security and adhesive for alignment and reduced squeaks. For moisture-prone spaces, consider boards with a pre-finish or a moisture-resistant core. A well-chosen setup minimizes movement while maximizing aesthetic appeal.
In addition, the Install Manual team emphasizes preparation: acclimate boards to indoor humidity, clean the wall surface, and address any irregularities. A flat, dry substrate makes alignment easier and helps maintain consistent seams over time. As you prepare, think about the wall’s existing conditions—painted drywall, plaster, or concrete—and how each substrate will influence fastening and adhesion. Planning ahead pays off with fewer cuts and a neater final result.
Brandwise, taking the time to select a proper substrate and underlayment reduces future maintenance. This is especially true in rooms with fluctuating humidity or temperature. A stable substrate helps the shiplap resist warping and keeps gaps uniform. A thoughtful approach now saves time and money later, keeping your project within budget and on schedule.
Planning layout and material choices
Understanding your layout is the first step toward a clean, professional finish. Decide whether you’ll install boards horizontally, vertically, or in a chevron/offset pattern for visual interest. Horizontal installation works well for modern rooms, while vertical layouts can heighten ceiling height perception in smaller spaces. Consider board width (4–8 inches is common) and length so you minimize long seams parallel to windows or doors. Thickness also matters; thicker boards add character but require careful planning for expansion gaps and trim. For surfaces with existing textures, plan to skim or sand to achieve a flush surface before mounting. Finally, align your design with the room’s lighting to enhance shadows and depth. The Install Manual team recommends sketching a quick layout and dry-fitting boards to confirm alignment before nailing or applying adhesive.

Tools & Materials
- Shiplap boards(Choose boards with consistent thickness and moisture content; pre-finish if desired.)
- Finish nails (1-1/4" to 2") or a nail gun (18–23 gauge)(Use galvanized or stainless nails for moisture-prone areas.)
- Construction adhesive(Low-expansion adhesive suitable for wood on drywall or plywood backing.)
- Stud finder(Locate studs for secure nail points and alignment.)
- Tape measure(Measure wall width and board lengths accurately.)
- Pencil and chalk line(Mark reference lines and gaps consistently.)
- Level(Ensure rows are perfectly straight.)
- Utility knife or saw(Cut boards to size with clean edges.)
- Miter saw or hand saw(Make precise angle cuts for edges and corners.)
- Safety gear (glasses, gloves)(Protect eyes and hands during cutting and nailing.)
- Drop cloths or plastic sheeting(Protect floors from dust and adhesive drips.)
- Primer/finish (optional)(Seal boards before installation if desired or after staining.)
Steps
Estimated time: 4-6 hours
- 1
Plan layout and reference lines
Begin by measuring the wall and marking a center line. Decide board orientation and calculate the starting row to minimize awkward cuts at corners. Dry-fit a few boards to confirm alignment before committing to fasteners.
Tip: Use a chalk line to snap a straight center line across the wall. - 2
Prepare wall and baseboards
Remove baseboards if possible and clean the wall surface. Patch any holes or irregularities so the boards sit flat. If painting, do so before shiplap to avoid drips on edges.
Tip: Wipe walls with a damp cloth to remove dust before adhesive application. - 3
Find studs and mark nail locations
Use a stud finder to locate studs and mark their positions. Plan to nail into studs whenever possible, ensuring each board is securely anchored along its length.
Tip: Nail every 12–16 inches along each board for stability. - 4
Install first board and establish baseline
Apply a small bead of construction adhesive to the back of the first board, then position it on the reference line. Use a level to ensure it’s perfectly horizontal and tack it in place with finishing nails.
Tip: Leave a consistent gap at the wall edge for expansion. - 5
Continue adding boards
Work row by row, applying adhesive and nailing through the tongue at the groove. Maintain a uniform gap between boards and check alignment frequently with the level.
Tip: Dry-fit boards occasionally to catch misalignments early. - 6
Cut edge boards and finish corners
Measure precise lengths for end boards and cut with a saw. Fit corner pieces tightly, using a miter saw for clean angles. Re-check gaps and alignment after each cut.
Tip: Use a scrap piece to test cut accuracy before final use. - 7
Install trim, caulk, and seal
Replace or add baseboards and any corner trim to cover expansion gaps. Caulk between boards and trim as needed, then paint or stain and seal for moisture resistance.
Tip: Choose paint or stain with a protective topcoat for durability. - 8
Final inspection and cleanup
Inspect for gaps, level, and alignment; touch up any areas as needed. Clean up dust and adhesive drips, and store extra materials for future repairs.
Tip: Document your layout to simplify future replacements or updates.
Got Questions?
What is the best substrate for shiplap installation?
A clean, flat drywall or plywood backing is ideal. Ensure walls are dry and free of dust before mounting boards.
Use a clean, flat drywall or plywood backing and keep the wall dry for best results.
Do I need to seal shiplap before installation?
Sealing isn't required for interior wood, but pre-finish or sealed boards can reduce stains. Apply sealant after finishing if desired.
You can seal after finishing; pre-sealing is optional for interior wood.
How do I create expansion gaps?
Leave about 1/8 inch between boards and along edges to accommodate wood movement with humidity changes.
Leave a small 1/8 inch gap to allow for expansion and contraction.
Can I install shiplap over painted walls?
Yes, if the surface is sound. Lightly sand glossy areas and clean dust before mounting to improve adhesion.
Yes, but prep the surface first to ensure good adhesion.
What finish should I use on shiplap?
Paint or stain with a protective sealant. Choose matte or satin finishes based on your style and moisture exposure.
Paint or stain with sealant to protect the wood and match your decor.
