Cut the reclaimed wood boards to countertop height minus 1/2". This will allow a 1/4" gap at the top and bottom. Lay out board widths to determine where the first and last pieces will fall. In this case, a structural and chunky look was desired, so old corner posts were used to flank the front. With the layout determined, start in the center of the wall and plumb the first piece with a level before attaching with construction adhesive and 2” finish nails, shot through the top and base plates of framing. Then install two finish nails in the center of each board. Cut boards that will be placed at corners to the proper width, install and then add corner trim (if needed). Once the cladding is installed, the top and bottom edges will need to be trimmed. In this case, a piece of reclaimed wood was ripped down to create top and base trim and installed with 18 ga. finish nails.
