Most modern board and batten sidings use wood as their primary material. This is also the same material that classic barns and country homes use.

Wood is a great material for board and batten because it is durable and it is widely available. However, more recent variations of board and batten siding use other kinds of materials that you might also want to consider for your home.

Board and batten siding is also available in vinyl, fiber cement, engineered wood, or steel. Most modern homes like the look of vinyl and steel because they are paintable and lend a more modern look to the siding.

However, those who prefer the classic look of wood prefer to use fiber cement or engineered wood. These materials mimic the appearance and feel of real wood, with better durability and strength. These materials are popular because of their weather- and rot-resistant qualities.

Installing a board and batten accent wall for your house is very easy. In most examples of these walls, DIYers also add shelving to the top of the board and batten walls for extra storage. Of course, you can simply remove this shelf if you'd rather the board and batten panels as the room's main focal point.

This video will give you a quick rundown on how to make a DIY board and batten accent wall. For this example, only the battens are added, and they use the blank wall of the room as the "boards" of the board and batten wall.

Materials Needed:

  • Tape measure
  • Level
  • Construction adhesive
  • Caulk
  • Brad nailer
  • Miter saw
  • Wood boards
  • Painter's tape
  • Primer and paint
  • Paint brushes or foam roller


1. Measure 

To begin this project, start by measuring the height that you want for your board and batten accent wall. Don't forget to consider the height of your baseboard if your walls have them.

Measure the width of the wall. If you have windows in that wall, make sure to measure each space individually. For the width, you need to add the width of the batten planks that you will use and subtract it from the width of the wall so you can space them properly.

Mark the areas where you plan to install the battens. The best way to do this is to start from the center, working your way outwards so that you'll have enough space to work with when you're spacing out the planks.

2. Cut The Boards

After measuring the wall, you need to cut the boards into the appropriate sizes. Separate the boards you will use for your horizontal and vertical battens. Mark the correct measurements on the board you will be using.

Using a miter saw, cut the boards according to size. Make sure that all the boards are of the same size to prevent boards from having an improper fit when installing them.

Cut the boards that you will use for the horizontal batten, as well as the vertical battens of your wall. If necessary, bevel the edges of the battens so that they will fit.

3. Install The Board And Batten

The first plank that you should install should be the horizontal batten of your wall. Apply a generous amount of wood glue on the back of the plank. Place it against the wall, and with a level, make sure that the plank is straight on both ends.

Secure the plank to the wall by using a brad nailer. Use nails on both the top and the bottom of the plank and wait for the glue to dry.

Do the same procedure for the vertical battens of your wall. After installing all of the planks, wait for the glue to set and dry completely before doing the next step.

4. Caulk All The Gaps

After installation, you will notice that the planks will have some spaces in between. Cover this up by applying a long bead of caulk to the sides of the board. Using your finger, drag the caulk down so that it will fill the gaps behind the planks.

Grab this caulk on Amazon.

Don't forget to caulk the joints and gaps in between the horizontal and vertical battens. Make sure to smoothen them so that they will not appear when you paint over the boards.,

5. Paint The Board And Batten Wall

After installing and caulking the boards, it is now time to paint them in your preferred color. Using a foam roller, apply a primer before putting down a layer of your chosen color. Wait for the paint to cure and you can now enjoy your new board and batten accent wall!
