Build a Shiplap Feature Wall

Shiplap has become the go-to move for anyone wanting to add texture and visual interest to a living room without knocking down walls or calling a contractor. The magic is in the shadow line—that deliberate gap between boards that catches light and makes the wall feel alive. What makes shiplap doable for a home owner isn't complexity; it's that the boards overlap by design, hiding imperfect cuts and installation mistakes naturally. A well-executed feature wall can anchor a room, frame a sofa, or draw the eye exactly where you want it. Done badly, it looks like something slapped on. Done right, it looks intentional and built to last. The difference comes down to starting level, cutting straight, and taking time with spacing.

1. Map Your Wall First. Measure the height and width of your chosen wall using a tape measure. Note any obstacles: outlets, light switches, windows, doors, baseboards. Sketch a quick layout on paper showing the full width and height. Calculate how many boards you'll need by dividing the total width by the coverage width of each board (usually 5.5 inches for standard shiplap). Add 10 percent for waste and mistakes. Check the wall for level using a 4-foot level in multiple spots—note any high or low areas. This mapping prevents surprises mid-project.
2. Clear and Clean the Wall. Turn off power to any outlets or switches on this wall at the breaker panel. Remove any wall art, outlet covers, or switch plates. Fill nail holes or damage with spackling compound and sand smooth when dry. Wash the wall with a damp cloth to remove dust, then let it dry completely. This gives your fasteners something clean and solid to bite into.
3. Build the Nailing Base. Furring strips (1x2 boards) create a nailing base and help compensate for wall irregularities. Mark the wall 16 inches apart vertically with a chalk line. Install the first furring strip at the base (above the baseboard) using a level as your guide. Fasten it to the wall studs with 2.5-inch screws every 16 inches. Work your way up the wall, installing strips level at each 16-inch mark. Use shims behind strips where the wall dips to maintain plane. The goal is a flat, rigid base for your shiplap.
4. Cut All Boards to Length. Measure the width of your wall precisely. Set up a miter saw on a sawhorse and cut your first board to exact length. Use a stop block clamped to the saw fence to ensure every subsequent board is cut to the same length—this eliminates measuring guesswork and saves time. Stack cut boards neatly nearby. If you have obstacles like outlets, mark them on the board and cut around them with a jigsaw before installation.
5. Start Perfectly Level. Install the first board horizontally along the baseboard, the tongue-side facing down so the groove faces up. Align it perfectly level using your 4-foot level. Use 1.5-inch finish nails or 18-gauge brad nails every 16 inches, driving nails through the furring strips into the studs. Nail through the top (hidden edge) of the board to avoid leaving visible holes. Check level every few fasteners to keep the row straight.
6. Lock in Shadow Lines. The second board slides up and over the first, lapping by roughly half an inch to create the signature shadow line. Before nailing, ensure the overlap is even across the entire board—use a spacer block if needed to maintain consistent spacing. Once satisfied with positioning, nail through the top edge of the lower board (into the furring strips) to lock the next board down. This overlap hides the fasteners and creates the visual rhythm.
7. Maintain Plumb as You Climb. Continue installing rows, maintaining consistent overlap and level as you climb. Every third or fourth row, stop and check that the wall remains plumb using a long level. If rows are creeping out of plumb, adjust the overlap slightly on the next few boards to correct course. This prevents the cascade effect where small errors compound toward the ceiling. Install boards until you reach the point where you need to cut boards to height for the top row.
8. Rip and Finish the Top. Measure the gap between the last full row and the ceiling. Use a table saw to rip shiplap boards to that width (rip along the length, not across). Install the top row just as you did the others, maintaining the same overlap and nailing through furring strips into studs. If the gap is less than 2 inches, consider removing the ceiling trim and allowing the top shiplap to butt directly against the ceiling for a cleaner look.
9. Fit Around Obstacles. For outlets or switches, measure the location carefully and mark it on the board before installation. Cut openings using a jigsaw, test-fit the board, and adjust as needed. For window or door frames, scribe the shiplap to fit tight against the trim using a scrap as a spacer. Install around the obstacle the same way as the rest of the wall—overlap, level, nail.
10. Fill and Feather Smoothly. Once all boards are installed, go over the wall with spackling compound, filling any visible nail holes. Use a putty knife to feather the edges. For the shadow lines between boards, some installers apply paintable caulk if they want a sealed, more formal appearance; others leave gaps raw for texture. Let spackling dry, then sand lightly with 120-grit paper to blend with the wall.
11. Prime, Then Paint Strategically. Apply one coat of primer formulated for wood (Benjamin Moore or Sherwin-Williams wood primer are solid choices). Prime all boards, including the edges and shadow lines. Once primer is dry, apply two coats of finish paint or stain according to manufacturer instructions. Use a brush for detail work in the grooves and a roller for the flat surfaces. Paint the edges of shiplap slightly darker or lighter than the field to emphasize texture, or keep it uniform for a modern look.
12. Reconnect and Test. Once paint is fully cured (check the can), turn power back on. Install electrical outlet and switch boxes in the cut openings, securing them to the shiplap or furring strips. Install new cover plates—choose plates that coordinate with your wall color or go neutral. Test all outlets to ensure power is restored and working properly.
