Installing Vertical Shiplap Over Drywall: A Comprehensive Guide

Embracing the rustic charm of shiplap has become a popular trend in home decor, and installing it vertically over drywall can add a unique touch to your space. This step-by-step guide will walk you through the process, ensuring a professional finish that's both functional and aesthetically pleasing.

Gather Your Tools and Materials
Before you begin, make sure you have the following tools and materials on hand:

- Tape measure
- Level
- Circular saw
- Jigsaw
- Hammer
- Nail gun or finish hammer
- Staple gun (for installing house wrap)
- Caulk gun
- Sandpaper (120-grit)
- Primer and paint (optional)
- Shiplap boards (ensure they're straight and free of knots)
- House wrap ( Tyvek or similar)
- Furring strips (1x3 or 1x4)
- Construction adhesive
- Finishing nails (1-1/4" or 1-1/2")
Prepare Your Wall Surface

Start by ensuring your drywall is in good condition. Repair any cracks or holes, and sand the surface smooth. Next, install house wrap over the drywall to create a barrier against moisture. Secure it with a staple gun, overlapping the seams and securing them with tape.
Install Furring Strips
Furring strips provide a surface to attach the shiplap boards and create a small gap between the wall and the shiplap for better ventilation. Cut the strips to the desired height of your shiplap installation, then secure them horizontally to the wall using construction adhesive and finishing nails, spacing them approximately 16" apart.

Measure and Cut Your Shiplap Boards
Measure the width of your wall and subtract the width of the first furring strip to determine the starting point for your shiplap boards. Cut the boards to the desired height, ensuring they overlap the furring strips by at least 1/2". Use a circular saw or jigsaw to make the cuts, and remember to account for the shiplap's tongue and groove when measuring.
Install the Shiplap Boards

Begin installing the shiplap boards at the bottom of the wall, using the first furring strip as a guide. Apply construction adhesive to the back of each board and set it in place, ensuring the tongue fits snugly into the groove of the board below. Secure the board with a finish nail gun or finish hammer, driving nails into the furring strips. Continue this process, working your way up the wall and using a level to ensure each board is straight.
Finishing Touches




















Once you've installed all the shiplap boards, use a nail set to countersink any protruding nails and fill the holes with wood filler. Allow the filler to dry, then sand the surface smooth. If desired, apply a coat of primer and paint to match your decor. Finally, caulk any gaps between the shiplap boards and the ceiling or floor to create a seamless finish.
Tips for a Professional Finish
To achieve a professional-looking result, consider the following tips:
- Choose shiplap boards with a consistent width and minimal imperfections.
- Stagger the joints between boards for added strength and a more attractive appearance.
- Use a nail set with a larger head to create a slight recess for easier countersinking.
- Apply painter's tape along the edges of the shiplap before caulking to create clean lines.
By following this comprehensive guide, you'll be well on your way to installing vertical shiplap over drywall like a pro. Enjoy the process, and happy building!
