Solution: Use Scarf Joints When Joining Lengths The key to a clean splice is a “scarf ” joint. Cut the first trim board about 1 in. short of a stud with a 30-degree bevel facing the room. Nail it into all the studs, then cut the second board with the same 30-degree bevel but in the opposite direction. Assemble the joint (no glue) to check the fit and recut a slightly greater or lesser angle as needed for a perfect joint. Smear wood glue on both bevels. Push the joint together, and then nail the overlapping piece into the stud near the joint. The overlapping bevel will clamp the one behind it against the wall. Wipe off the glue squeeze-out with a damp rag right away. If you’re installing clear finished baseboards with a prominent grain pattern, select two pieces that match as closely as possible.
