Stain the bead board to match your kitchen cabinets. Use oak stain, for example. Add the bead board to an existing surface by using a nail gun stapler. Glue the bead board as another option, especially if the underlying surface is curved. Install bead board sheeting on a peninsula wall that is curved or rounded by gluing it on and then nailing it in place.
Paint the bead board and all trim white to match white kitchen cabinets. Cut the bead board to fit just under the lip of the countertop. Nail up narrow sections of wood trim to cover any gaps if you don’t wish to add crown molding.
Dress up any section of the bead board paneling with crown molding to give the peninsula a high-end look. Use heavy crown molding on straight surfaces. Nail crown molding along the floor, for example, and paint it with high gloss paint so it can be wiped down easily to remove scuff marks.
Cut the bead board on a diagonal as one option. Nail up sections of bead board with lines running at a 45-degree angle instead of having vertical or horizontal lines. Use this method on peninsulas with straight surfaces only. Don’t try to install paneling on a diagonal if the bar surface is curved in any way.
Add pre-made cabinet doors over bead board. Use wood trim to cover an opening in the bar peninsula. Install hardware over the bead board. Paint or stain cabinet doors to match the bead board exactly. Leave openings for shelving without doors when using bead board, but fit molding around the raw edges to give shelving areas a finished look.
