What Is Shiplap
Definition: Horizontal (or vertical) wood boards with a rabbeted edge that creates a uniform gap between boards. Originally used as exterior siding on barns and houses. Now popular as interior decorative wall and ceiling treatment. Creates the iconic farmhouse, coastal, and modern look.
Gap (shadow line): The rabbeted (notched) edges overlap to create a consistent gap. Standard gap: 1/16 to 1/8 inch (nickel-width). This shadow line creates the distinctive shiplap look.
Types
Solid wood shiplap: Pine (most common): $2-$5/sq ft. Cedar: $4-$8/sq ft. Poplar: $3-$6/sq ft. Available in 1/2 or 3/4 inch thickness. Can be stained or painted. Most authentic look and feel.
MDF shiplap: Pre-primed, ready for paint. Cost: $1.50-$3/sq ft. Lightweight, easy to cut. Cannot be stained. Smooth, consistent surface. Most affordable option.
PVC/vinyl shiplap: Moisture-proof (great for bathrooms). Cost: $3-$7/sq ft. No painting or maintenance needed. Comes in white and limited colors. Best for wet areas.
Plywood shiplap (budget hack): Rip 1/4 or 1/2 inch plywood into 6-8 inch strips. Cost: $0.50-$1.50/sq ft. Budget-friendly DIY option. Requires more work (ripping strips, spacing). Less consistent than pre-milled.
Design Ideas
Accent wall: Most popular application. Behind bed (headboard wall). Living room fireplace wall. Bathroom vanity wall. Entryway or hallway feature wall.
Full room: All four walls for complete farmhouse look. Can feel overwhelming in small rooms. Works best in white or light colors for full rooms.
Ceiling: Dramatic overhead treatment. Makes rooms feel more finished. Popular in bedrooms and covered porches.
Direction: Horizontal: most traditional, makes rooms feel wider. Vertical: more modern, makes ceilings feel higher. Diagonal: bold statement, more cutting waste.
Color: White: classic, clean, most popular. Natural wood: warm, rustic. Gray: modern farmhouse. Dark (black, navy): dramatic accent wall. Two-tone: different color above and below chair rail.

DIY Installation
Tools: Brad nailer (18 gauge). Level. Tape measure. Miter saw or circular saw. Stud finder. Caulk gun.
Steps: Find and mark studs. Start with a level bottom board (use level line, not baseboard as reference). Apply construction adhesive to back of board. Nail into studs with brad nails (18 gauge, 1.5-2 inch). Use nickels or spacers for consistent gap between boards. Stagger seams (don't align end joints). Continue up the wall. Rip the final board to fit at ceiling. Caulk any gaps at edges. Paint (2 coats, use roller for faces and small brush for gaps).
Tips: Acclimate wood 48 hours in room. Paint boards before installation (faster, better coverage in gaps). Remove outlet covers and extend boxes with box extenders. Start from the bottom and work up.
