Creating a half shiplap wall is a transformative project that adds texture, dimension, and a touch of rustic charm to any room. Unlike a full shiplap installation that covers an entire wall, this method focuses on the upper portion, creating a striking visual focal point that draws the eye upward. This guide will walk you through the entire process, from initial planning to the final paint application, ensuring a professional-looking result.
The concept is simple: you install horizontal boards on the bottom two-thirds of the wall and leave the top third smooth. This contrast allows you to retain the classic shiplap aesthetic—characterized by its overlapping "T" or "V" shaped joints—without overwhelming the space. It is an ideal solution for bedrooms, living rooms, or entryways where you want character without the commitment of a full wall makeover.
Planning Your Half Shiplap Layout
Before pulling a single nail, meticulous planning is essential to ensure your half shiplap wall aligns perfectly. Start by determining the height of the shiplap section. A common guideline is to install it approximately two-thirds of the way up the wall, but you should adjust this based on your ceiling height and personal preference. For standard 8-foot ceilings, this usually means finishing the shiplap around 5 feet from the floor, leaving a 3-foot smooth plaster or drywall section above.
Next, you must decide the orientation of the boards. While shiplap is traditionally installed vertically to make a room feel taller, half walls look stunning when run horizontally. Horizontal lines create a sense of stability and make a room feel cozier. If you choose vertical installation for the bottom section, ensure the overlapping joints are staggered with the joints in the smooth top section to avoid a static and repetitive look.
Tools and Material Checklist
Gathering the right materials ensures a smooth installation process. You will need shiplap boards (real wood or high-quality engineered wood), a miter saw for precise angle cuts, a power drill with appropriate bits, finishing nails or a nail gun, a level, measuring tape, and construction adhesive. Depending on your wall condition, you might also require thin-set mortar for very smooth surfaces or backer board if you are installing over tile.

Preparing the Wall Surface
A flawless finish starts with a prepared surface. Inspect the wall for any holes, cracks, or unevenness. If you are working over drywall, fill any imperfections with spackle and sand them smooth once dry. If you are installing over existing paneling or tile, the shiplap may require a flat base to adhere correctly; in this case, install a layer of 1/4-inch plywood backer board using construction adhesive and screws.
Crucially, you must locate the wall studs. Use a stud finder to mark the vertical wooden frames behind the drywall. Marking the studs is vital because the shiplap boards need to be secured directly into them for maximum holding power. While you can use adhesive, nailing directly into the studs prevents sagging and ensures the wall remains sturdy for years to come.
Installing the Bottom Row
Begin the installation at the bottom of the wall, where the floor meets the drywall. Cut your first board to length, ensuring it extends slightly past the final stud. Apply a bead of construction adhesive to the back of the board and align it with the floor. Use your level to confirm that it is perfectly horizontal, then nail the board into the first stud on the left and right sides.
Maintaining consistent gaps is the hallmark of professional shiplap work. Use plastic shiplap spacers—typically 1/16th of an inch—placed at the top and bottom of each board to ensure uniform spacing for expansion and contraction. As you move across the wall, cut subsequent boards to fit the remaining space, remembering that the boards will overlap the previous one. Always stagger the vertical joints by at least 12 inches to create a visually pleasing pattern.
Finishing the Transition
As you approach the top of your designated shiplap zone, you will likely encounter the row that sits directly under the smooth wall section. This is where precision is critical. Measure the remaining gap carefully and cut your final board to fit snugly. If the gap is irregular, you may need to rip the board to the exact width using a table saw or circular saw with a guide.
Before painting, double-check that all boards are secure and the gaps are even. Fill the nail heads with wood filler and sand them flush. This step is critical because the top section of the wall will likely be painted a contrasting color, and any visible nail heads or imperfections will be starkly obvious against the smooth surface.
Painting and Final Touches
The final step in achieving a stunning half shiplap wall is the paint selection. Lighter colors like white, cream, or soft grays create a bright, airy feel and make the texture of the wood pop. Darker tones, such as deep greys or navy, offer a dramatic, sophisticated look that pairs well with modern decor.
Apply painter’s tape to protect the adjacent smooth wall and floor. Cut in with a brush along the edges and corners, then use a high-quality roller to cover the shiplap boards. Avoid overloading the roller to prevent paint from pooling in the gaps. Once the paint is dry, remove the tape cleanly to reveal a crisp, professional finish that highlights the unique geometry of your half shiplap design.
