Measuring and Marking Techniques

First, measure the wall for the molding length. Then, mark the back of the molding where you’ll cut. Remember, accurate measuring is crucial for a perfect fit.

Cutting Techniques: Miter Cuts and Coping Cuts

For outside corners, use miter cuts. Set your saw to the correct angle, usually 45 degrees, and cut. For inside corners, coping cuts work best. Cut one piece at a straight angle to fit flat against the wall. Then, use a coping saw to shape the end of the other piece, ensuring a tight joint.
