Introduction #

Chevron is one of the four ways to run shiplap, and the boldest one on a wall. Mirrored boards meet end to end at a center line and form one continuous, unbroken V. People confuse it with herringbone constantly, so get the difference straight first: herringbone boards butt against the side of their neighbor, building a stepped, broken zigzag, while chevron boards meet end to end at a shared center seam, mirrored at the same angle, reading as one continuous point instead of a step. Shiplap itself is a form of wall trim, and if you want a general primer on trim and moulding technique beyond this shiplap chevron variant, the This Old House trim guide is a good supplement.

The boards themselves go together the same way they do on a horizontal wall. Today’s shiplap is tongue and groove, or sometimes a flat, square-edge board run with a consistent gap, never a rabbeted lap joint. What is different here is the layout: striking a true center line, holding one miter angle on every cut, and keeping that seam tight for the full height of the wall.

We do not use a plywood backer on chevron, or any shiplap orientation, ever. We glue instead, construction adhesive on the back of every board, face nailed on top - call it out to the customer or GC up front. This is a reference variant guide and covers only what changes for chevron: it is the most demanding orientation to run, every board takes an angled cut on both ends, waste runs high, and a miter off by even half a degree shows at the center seam. Order more material than the square footage suggests.

Before You Begin #

Before you start, make sure these things are ready, and read through what is different about chevron below.

Prerequisites #

• Wall surface ready, almost always drywall (occasionally OSB, if the GC hung it - their call)
• No backer needed - we plan for drywall, so boards glue and face nail directly to the wall. If the customer has sheeted it in OSB or plywood, take the win: fasten straight to it and skip the glue
• Boards on hand are tongue and groove, or square-edge with spacers for a consistent gap
• If prefinished, common for chevron, confirm every board is from the same finish lot before you cut
• Extra material ordered - the most cut-heavy and waste-heavy orientation, less forgiving than herringbone
• Material acclimated to room humidity for 48 hours, stacked flat with spacers between layers
• Center line roughed out and the wall measured for it (Step 1)
• Outlet and switch locations marked, and power killed at the breaker before any cutting near a box

What You Need To Know #

• The center line is the whole job - every V point stacks on the one below it, and drift shows as a jog with no hiding it
• Every board gets the same angle cut on both ends. That is the real difference from herringbone: mirrored boards meet at the center line as one continuous point, not a butted step
• We glue every board. Adhesive is what holds the wall up over time, since there is no backer and no reliable stud hit at these angles - face nails just hold the board while the glue sets
• We almost always face nail, same 18-gauge brad as any shiplap orientation. Keep nail placement consistent - a stray head catching the light stands out fast
• Smooth, painted shiplap is almost always MDF. It does not split at a sharp mitered point the way solid wood can, and it fills and sands easily

Tools Required #

Power Tools #

• Miter saw with a reliable, positive stop
• 18-gauge brad nailer, for face nailing the field
• 15-gauge finish nailer, for the edge trim
• Table saw, for square-edge boards and the last-piece fit (Step 5)
• Stud finder, to note what is behind the wall before you glue
• Jigsaw or oscillating multi-tool, for outlet and switch cutouts

Hand Tools #

• Tape measure
• Pencil
• Chalk line, for striking the center line
• 6-foot level for most of this job, with a 4-foot, 2-foot, or 8-foot on hand for whatever else comes up
• Speed square or T-bevel gauge, for checking your saw’s angle against scrap
• Caulk gun, for the construction adhesive
• Utility knife

Supplies #

• 18-gauge brad nails, 1-1/2″ to 2″
• Construction adhesive - carries the wall instead of a backer board
• Wood glue, for the mitered center seams - puttied and sanded once cured, that part is ours
• Spacers (nickels or 1/8″ shims), for square-edge boards

Materials #

• Shiplap boards, tongue and groove or square-edge, prefinished if that is the spec
• Construction adhesive and wood glue (see Supplies)
• Edge trim or casing stock, for the boundary where the pattern meets the ceiling, floor, and side walls

How to Install Chevron Shiplap #

Chevron comes together in five stages: strike the center line, dial in the angle, set the first pair, run the field, fit the edges. Spend your time on the first two.

Step 1: Prepare the Wall and Strike the Center Line #

Confirm your wall surface - almost always drywall, occasionally OSB if the GC hung it. No plywood backer, no furring strips. Find true center by measuring the wall’s width at a few heights, since walls are not always square. Mark the center point top and bottom, strike a plumb chalk line between them, and check it with a level. This line is where every board meets its mirror.

Pro Tip: A chalk line covers the full height in one snap and stays straighter over distance than walking a level up in sections.

Step 2: Dial In Your Miter Angle #

A classic chevron uses a 45° cut on each end, forming a 90° point. Whatever angle you pick, it must be identical on every cut, both ends, every board - that is what makes a chevron a chevron and not a herringbone. Cut several test pairs from scrap, flip one, and check the joint. Dial in the saw until pairs meet with no gap, then leave the angle alone for the rest of the wall.

Step 3: Set the First Pair at the Bottom Center #

Start at the bottom of your center line. Cut a mirrored left and right board and dry fit the pair to confirm a tight point with no gap. Run construction adhesive on the back of each board, this holds the wall over time, then press both into place and face nail to hold them tight while the glue sets. You will not hit a stud on every nail at this angle, and that is fine. Glue the mitered seam itself too, not just the backs, for a joint that stays tight as the wood moves.

Step 4: Work Up the Wall in Mirrored Pairs #

Engage the tongue and groove the same way you would on a horizontal wall, or hold your gap with spacers on square-edge stock. Glue and nail every board, keeping nail placement consistent. Check point-to-point alignment every row or two - drift shows up as a jog almost as soon as it happens, and it is far easier to correct one row than to pull five.

Step 5: Fit the Final Pieces at Each Wall Edge #

The wall-edge end of each board runs long while you cut the pattern, then gets trimmed flush once you reach the actual ceiling, floor, or side wall - snap a line and trim with a straight edge guide. Some pieces, especially the last one, will not have room to angle into their groove. Take a few measurements across the gap first, since it is rarely a consistent width. Rip the back edge off the groove on a table saw so the piece drops straight in, then bevel that edge back about 10° so the face sits tight. Cover the trimmed edges with trim.

Close-Out After You Install Chevron Shiplap #

Close out a chevron wall the same way as any other shiplap orientation, with a couple of things specific to this pattern.

• Set every nail head below the surface. Angled cuts hide a proud head easily, and they catch raking light fast on a bold pattern.
• Putty and sand the center seams. Once the glue cures, putty any hairline gaps in each mitered V-joint and sand flush - a wood-to-wood joint, ours to close clean, not the painter’s.
• Wipe glue squeeze-out while it is still wet, both the adhesive on the back and the wood glue at the seam.
• Sweep up - cutoffs collected, dust off the floor and sill.
• Install trim at every edge where the pattern meets the ceiling, floor, or side wall.

If this wall is paint-grade, the handoff is the same as always: nails set, glue cleaned off, trim installed, floor swept, filling nail holes is the painter’s scope. If prefinished, which is common for chevron, there is no paint coat coming to blend a filled hole. Flag that with the customer or GC before you set the first nail - prefinished holes need color-matched putty crayons or wax sticks, not standard filler.

Quality Check After You Install Chevron Shiplap #

• Center V-seam glued, puttied, and sanded flush, no gaps down the wall
• V-points stacked directly above each other, plumb, top to bottom
• Left and right boards in every pair match in width and angle
• Every board glued to the wall, no hollow spots when you press on it
• Nail heads set below the surface and not catching raking light
• Wall-edge ends trimmed flush and covered by trim
• Prefinished boards consistent in sheen and color across the wall

Troubleshooting #

Even careful layout runs into problems. Here is what usually causes them on a chevron wall.

Center seam has gaps at the V-point #

Your miter angle is off - even 0.5° of error shows at the point. Re-test the saw on scrap and recalibrate before cutting anything else. Re-cut and reset the affected boards rather than filling the gap; a filled V-joint opens back up as the wall moves, and it is the most visible spot in the pattern.

The pattern is drifting off center #

The center line was not truly plumb, or small errors compounded over several rows. Stop as soon as you notice it - every row you add while it drifts makes the fix bigger. Re-check the line with a level and expect to pull a few rows to get back on line.

Boards split at the mitered point #

A sharp miter point splits easily when you nail near it, especially in solid wood. Drill a pilot hole before nailing within 2″ of any angled end, or use a shorter brad. Painted shiplap is likely MDF, which resists this on its own.

Nail heads show in raking light #

Usually inconsistent placement board to board, or a head that is not quite set below the surface. Keep your nailing line consistent, set every head fully, and check the wall in the light it will actually be seen in before you call it done.
