Measure, Mark and Cut the Beadboard
Use a stud sensor to locate and mark the wall framing. Plan the installation to start at a left-side corner and work outward across the wall to the right. In a conventionally framed room with wall studs 16” on-center, each 4x8 ft. panel should end (and begin) on a stud.
If you are installing over an existing wall surface, trim a piece off the left edge of the starter panel to allow for the thickness of the existing material. Don’t make this cut on the right edge – panels are made with lap joints on the side edges, and the joint on the right edge is needed to hide the first seam (Image 1).
Measure and cut the beadboard panels with a circular saw to the required height and width, if necessary.
Also carefully measure and mark any openings for electrical boxes or other penetrations. Use an electrical box as a template to transfer the cutout dimensions onto the panel, and use a 1/4" drill bit to bore pilot holes in the corners. Make the cut with a jig saw (Image 2).
