Add your trim boards
Now it is time to bring your design to life! I got all my trim boards from 84 Lumber. They are super high quality and the ones I got were pre-primed which saves a ton of time if your plan is to paint! My boards are all 1×4 dimension.
The best part of having 84 Lumber supply my wood for this project was that they delivered it to my front door (garage, really)! It was super easy and way better than going to pick up in person. That said, if you need to go in person, they also have a lot of locations to choose from so be sure to look them up!
Quick tip: If your baseboard has a tapered top like mine, you have two options.
With this design, I recommend starting with the top and bottom horizontal boards.
Once the top (ceiling) and bottom (baseboard) trim boards are cut, it is time to hang them! Make sure they are level and nail into the wall. I don’t recommend using glue because that will tear up your drywall if you decide to remove the trim down the road.
Now it is time to cut and hang your vertical boards.
Quick tip: make a spacer board the size of your wainscoting space between boards (see the board spacing from the calculator referenced in step 3). The spacer makes it super easy to get the exact same spacing between your trim boards every time, without having to continually check and measure.
When the vertical boards are all up and spaced appropriately, you will begin adding your horizontal boards. These will actually be the same size as your spacer used above! So, if you’d like, you can use a trim board as a spacer and then as your template for the other horizontal boards. This design has one square at the top and one larger rectangle at the bottom. Again, you can use your spacer board from before to determine the spacing for the horizontal board. You will just nail in place the same as before.
Add Details
Ok, your wall is already gorgeous, but if you want to take it to another level consider adding some additional base cap trim inside your wainscoting panels. These will need to have mitered or angled edges so they will meet up in the corner of your piece. They do take a little practice but once you get the dimensions right it goes super quickly. And don’t worry if they are 100% perfect. Caulk can conceal any imperfections.
So, speaking of caulk, now it is time to caulk all of your mitered trim corners and all along the edges of where the trim meets the wall. This creates a nice clean look and eliminates any gaps. I like to add a thin line of caulk, smooth it with my finger, and go over it with a damp paper towel to remove any excess. Also be sure to fill all your nail holes with spackle and either wipe away excess with a damp cloth or sand it gently once it is dry for a smooth finish.
Lastly, it is time to paint all the trim! Using a paint brush, paint all of your added trim with two coats of paint matching your wall color. Now is a good time to do any additional touch ups to the wall if need be as well. Once the paint is dry, stand back and admire your feature wall because this one is GORGEOUS! You will not be disappointed in the work you put in for this incredible project.
