As you can see in the picture below, adding the trim work to the top of our wood plank walls made a huge difference.

It was SUPER easy to do.

You only need three trim pieces.

* 1×4 wood trim piece

* stool trim piece

* base cap trim piece

We purchased all of our trim pieces from Lowe’s.  I took pictures of the two smaller trim pieces for you…

First, nail the 1×4 trim piece to the top edge of the wood plank wall.

Secondly, nail the “stool” trim piece on top of the 1×4 trim piece.

Lastly, nail the base cap {upside down} underneath the “stool” trim piece.

Be sure to fill in all the nail holes with wood filler and sand if needed.

Then paint the trim work, and you are finished!



It’s the little finishing details that can make a big difference!  It definitely gives the space a more custom look.

  1. Thank you so much for this in formation. I’ve had an unfinished beadboard half-wall in my laundry room for more than 2 years now and I’m ready to cap it off. This is the perfect solution. Well done. Jo @ Let’s Face the Music

  2. You have saved me a lot of hassle by sharing those simple instructions! I am using thicker beaded board in my bathroom and was stressing out about how to trim it (it’s too thick for a “cap”)
    Thank you for sharing :)
