Shiplap Installation: A Step-by-Step DIY Guide for Walls That Look Pro

A weekend of shiplap installation can transform a bland room into the kind of space that feels custom-built. The popularity exploded after Joanna Gaines put it in every Magnolia project, and a decade later it still works in farmhouse, coastal, and modern interiors. The trick is treating it like a real carpentry project rather than slapping boards on a wall. Tight reveals, level courses, and proper nailing make the difference between a feature wall and a sloppy DIY mess.

I have installed shiplap in dining rooms, bathrooms, mudrooms, and entire ceilings. The process is the same regardless of room. Plan the layout, prep the wall, work top to bottom or bottom to top with consistent reveals, and finish with caulk and paint. A 100-square-foot wall takes one person about six hours including paint.

Choose Your Shiplap Material

Real tongue-and-groove shiplap from a lumberyard is the premium option but costs $4 to $8 per square foot in primed pine. Most homeowners use one of three more affordable alternatives.

• True shiplap boards: Pine, cedar, or poplar with a milled rabbet that creates the iconic gap. Best look, highest cost
• Nickel-gap MDF panels: Pre-primed 4×8 panels with a built-in reveal. From Metrie or PrimedRX. About $40 to $60 per panel ($1.50 to $2 per sq ft)
• Plywood ripped into planks: Buy 4×8 sheets of 1/2-inch sanded plywood ($45 each), rip into 6-inch strips on a table saw. About $0.80 per square foot
• Pre-made shiplap from Home Depot: UFP-Edge sells primed pine shiplap for $1 to $2 per square foot. Decent quality, fast install

For most homeowners, the UFP-Edge boards or nickel-gap MDF panels offer the best balance of look, ease, and cost. Plywood-rip is the cheapest if you have a table saw and patience.

Tools and Materials You Need

• Brad nailer or finish nailer with 1.5 to 2-inch nails (rent for $35 a day if you do not own one)
• Compressor or cordless equivalent (the Ryobi 18V brad nailer is $200 and skips the hose)
• 4-foot level
• Stud finder
• Pencil, tape measure, chalk line
• Miter saw or circular saw with a square
• Caulk gun and paintable caulk
• Spackle for nail holes
• Pre-mixed primer (if not using pre-primed boards)
• Two coats of paint in your chosen color
• Nickels or 1/8-inch spacers for reveals (if using boards without built-in spacing)

Step 1: Prep the Wall

Remove baseboards, crown molding, and outlet covers. Patch any major holes with spackle. You do not need to remove existing paint or wallpaper unless it is peeling.

Find and mark every stud with a vertical pencil line from floor to ceiling. Studs are typically 16 inches apart, but in older homes they can vary. Most shiplap installations require nailing into studs, not just drywall.

Step 2: Plan the Layout

Measure the wall height and divide by your board width plus the reveal. For 6-inch boards with a 1/8-inch gap, each course covers 6.125 inches. A 96-inch wall needs about 16 courses. If the math leaves a sliver less than 2 inches at the top or bottom, adjust by ripping the first or last board narrower so the top and bottom courses look balanced.

Decide on horizontal or vertical orientation. Horizontal is the classic look and visually widens a room. Vertical adds height and works better in small bathrooms and entryways.

Step 3: Snap a Reference Line

Use a 4-foot level to find the lowest point on the floor. Measure up the height of one board plus 1/8 inch and snap a chalk line across the wall. This is your reference for the first course. Floors are rarely level, so trust the chalk line, not the floor.

For ceilings, measure down from the highest point of the ceiling instead.

Step 4: Install the First Course

Cut the first board to length. Hold it in place with the top edge on the chalk line. Verify it is level (it almost never will be perfectly with the floor underneath). If there is a gap at the bottom, you can hide it later with baseboard.

Nail the board into every stud at the top and bottom. Use two nails per stud, angled slightly inward, about 3/4 inch from each edge. Tongue-and-groove shiplap can be blind-nailed through the tongue at a 45-degree angle so the next board hides the nail.

Step 5: Continue Course by Course

Place the next board with the bottom edge resting on the top edge of the first board. Use 1/8-inch spacers (nickels work) at multiple points along the length to maintain consistent gap if your boards do not have built-in nickel-gap reveals. Nail off into studs.

Stagger the seams. End butt joints should not stack vertically; offset them by at least 16 inches between courses. This looks more natural and is structurally stronger.

Step 6: Cut Around Outlets and Obstacles

Mark outlet locations with a pencil on the back of the board before installing. Use a jigsaw or oscillating multi-tool to cut. Outlet boxes need to be extended out with plastic outlet box extenders ($1 each) so the receptacle sits flush with the new shiplap surface. This is a code requirement, not optional.

For windows and door trim, scribe the board edge to fit around the casing. Take your time; visible gaps next to trim look amateur.

Step 7: Finish the Top Course

Measure the remaining wall height and rip the final board to fit. Set the rip cut against the ceiling so the cut edge is hidden by crown molding (if you are using crown) or caulk.

Step 8: Fill, Caulk, and Paint

Fill nail holes with spackle. Sand smooth. Caulk all corners, around windows, around outlets, and along the ceiling and baseboard with paintable caulk. Do NOT caulk the reveals between boards; that is the whole point of the look.

Prime any unprimed boards. Then apply two coats of paint with a 4-inch foam mini roller for the flat surface and a 2-inch angled brush for the reveals. Pure White (Sherwin-Williams 7005) and Simply White (Benjamin Moore OC-117) are the most popular shiplap colors. Hale Navy and Iron Ore (SW 7069) make stunning dark shiplap walls.

Common Mistakes to Avoid

• Not removing baseboards first; the result looks unfinished
• Inconsistent reveal width across courses
• Stacking butt joints vertically instead of staggering
• Caulking the reveals (eliminates the entire shiplap look)
• Skipping the outlet box extenders
• Nailing into drywall instead of studs
• Using wood that has not acclimated to the room for 48 hours (causes gaps and warping)

Cost Per Square Foot

Material costs depend heavily on your choice of board.

• Plywood-rip: $0.80 to $1.20 per sq ft
• UFP-Edge primed pine: $1 to $2 per sq ft
• Nickel-gap MDF panels: $1.50 to $2.50 per sq ft
• Premium tongue-and-groove pine: $4 to $8 per sq ft
• Add $0.50 to $1 per sq ft for paint, caulk, and nails

A typical 100-square-foot accent wall costs $150 to $400 in materials. Hiring a carpenter adds $400 to $1,200 in labor.

Where Shiplap Works Best

Shiplap shines in entryways, dining rooms, mudrooms, and bathroom accent walls. Avoid it in bathrooms with poor ventilation (the gaps trap moisture) and in modern minimalist homes where the texture clashes with clean architecture. Ceilings are an underrated application that adds character without dominating the room.

FAQ

How hard is shiplap installation for a beginner?

Moderately easy. A first-time DIYer can install a 100-square-foot accent wall in a weekend with a brad nailer and basic carpentry skills. The trickiest part is keeping reveals consistent and cutting around outlets cleanly.

Do you nail shiplap to drywall or studs?

Always nail into studs. Drywall alone will not hold the boards securely. Use a stud finder and mark stud locations with a pencil line from floor to ceiling before installing.

Should you caulk between shiplap boards?

No. The reveal between boards is the defining feature of shiplap. Only caulk corners, edges, around windows, and at the ceiling and baseboard.

What is the best paint for shiplap?

Use a high-quality acrylic enamel in satin or eggshell. Sherwin-Williams Emerald and Benjamin Moore Aura both produce a smooth, durable finish that highlights the texture without showing brush marks.

How much does it cost to install shiplap on a wall?

DIY material costs run $1 to $4 per square foot. A 100-square-foot wall costs $150 to $400 in materials. Professional installation adds $400 to $1,200 in labor for the same wall.
