How to Install Wall Frames

Using a chip brush, apply wood glue to the mitered ends of two adjoining pieces of molding and position them around the jig. Line up the corner so that the edges are flush and square, tight to the jig. Clamp the molding in place to the jig. Using a brad nailer and 2-inch nails, secure the mitered corner of the frame by shooting two nails into the fattest part of the molding. Continue assembling the frame corner by corner until complete. Make all the frames and set them aside.
