The Different Ways of Finishing Shiplap Edges
If you’ve read my blog for a while, you know I like to give the info at the top for an easy read and then go into further detail, so here we go, the different ways to finish shiplap edges:
- Paintable Caulk
- Corner Trim
- Trim Boards for the along the Ceiling and Floor
- Half Wall or Accent wall trim
Using Caulk on Shiplap Edges
The easiest way to trim shiplap edges doesn’t involve any trim at all. It’s Caulk! Caulk will give your shiplap edges a professional quality and make them look clean and polished. It’s the best way to hide seams in your shiplap walls as well.
Make sure to get paintable caulk. It can be used on any gap or blemish, and is really forgiving to help hide mistakes. It helps hide seams in wallpaper as well.
I have certainly made SEVERAL mistakes for sure when installing shiplap, especially when painting shiplap.

First, load your caulk gun and run a bead along the shiplap edge or corner.
Then, this is my favorite part, take a baby wipe and smooth the caulk into the groove between the shiplap edge and the wall and just watch the magic. If you don’t have baby wipes on hand, just wet your finger with some water and repeat the same process.
Next, while the caulk is still wet, check along all the shiplap edges and cracks for large globs or excess caulk and wipe that away. It is a lot harder to remove it once it dries.
After the caulk is dry, you can paint your shiplap!
Trim Boards for Shiplap Edges
Trim is another way shiplap edges can be finished. It is a great way to give the shiplap wall or walls different personalities and distinguish between different styles.
I like using very simple and classic trim so the shiplap feature walls have the spotlight, while you may prefer a cleaner, more modern trim.

Whatever kind of trim you used on the sides, the installation process is the same.
First, Measure your sides and cut trim to length. Depending on the size of trim for the shiplap, use a miter saw, miter box, or miter shears to cut it.
Next, Nail on your trim. You can use construction adhesive or some kind of glue on the back of the trim, but I change my mind with feature walls so often I just nail them in with my nail gun.
Finally, fill any holes in the shiplap trim with wood filler and let dry. Once dry, sand it smooth before painting. Caulk the shiplap corner edges also before painting.
Different Trim Styles to Finish Your Shiplap
Here are a few different options for shiplap trim in pictures


Inside and Outside Shiplap Corner Trim Recommendations
Adding shiplap to a room is one of my favorite ways to add character and charm to a space. If you are anything like me, your installation is not going to be perfect.
A great way to conceal any gaps or mistakes in the corners is to install corner trim. For outside corners, install this trim on outside corner, for inside corners, install this one.


Trim Boards for Shiplap Walls Along Ceilings and Floors
For the ceiling, crown molding is my favorite option. It is a classic option and will instantly lift the look of the your shiplap walls. If you are doing a single wall of shiplap, a wide flat trim along the ceiling and the sides of the shiplap edges will finish it off nicely too.
When choosing a baseboard for your shiplap accent walls, choose your preferred style before purchasing your shiplap boards or trim boards.
Once you’ve chosen your baseboards, grab shiplap boards that are the same thickness or slightly thinner than the baseboard.
We chose to do a contrasting color here on the baseboards in Stone Hearth by Benjamin Moore.


Other Trim Choices for Shiplap Walls
Shiplap, like a lot of wood these days, is expensive. A way to get the look for less is to do a half wall or half lap, or one accent wall.
Accent Walls
A single accent wall of shiplap will be layered on top of a baseboard, so the only shiplap edge trim that is really needed is along the sides. Choose one of the previously suggested trims for shiplap and install in the same way.

If your room already has crown moulding, you can take the shiplap to the bottom edge of the molding or add another piece of trim directly below the bottom edge on top of the unfinished shiplap edge right below the crown moulding.
Half Shiplap Walls
I love how a half vertical shiplap walls look in a home. It’s easy to add the finishing touches to these walls, simply add a 1×4 board above the top edge of the shiplap. If you want to make a ledge for pictures and other trinkets to sit on, add a 1×2 or 1×3 on top 1×4 trim board.

On a horizontal half shiplap wall, nail a 1×2 or 1×3 to the top edge of the last shiplap board. It is recommended that the shiplap wall treatment goes about two thirds up the wall. For example: if your ceilings are 9 ft, add ship lap 6 ft up the wall.
Shiplap Door Trim
Another question asked a lot about trim for shiplap is shiplap door trim. I recommend if you are shiplapping a wall with a door or doors, make sure your door trim is installed first.
Any door trim will look nice against the shiplap, but I would do it before adding the shiplap to the wall. Don’t forget to caulk the edges where the shiplap meets the door trim.
