Choose the Right Materials
Select paintable caulk for edges that might need painting later. This ensures a smooth and adaptable finish that blends seamlessly with your wall colors.
Steps to Caulk Shiplap Edges

- Apply Caulk:Ā After installing your shiplap, apply a bead of caulk along the edges where the shiplap meets the wall, corners, or moldings.
- Smooth Out the Caulk:Ā Immediately smooth the caulk with your finger or a damp cloth to ensure it fills all gaps evenly without leaving excess.
- Cleanup:Ā Wipe off any excess caulk with a lint-free cloth while itās still wet to prevent bumps or ridges.
Using Trim to Finish Edges
For a more defined edge, consider adding trim such as quarter-round or crown molding. This not only covers any gaps but also enhances the overall aesthetic of your shiplap installation.
- Measure and Cut:Ā Accurately measure and cut your chosen trim to fit the edges of your shiplap.
- Secure the Trim:Ā Attach the trim using strong adhesive or nails for a durable finish.
- Final Touches:Ā Fill any nail holes with caulk and paint over the trim as needed.
To make it even easier, have Home Depot or your local store cut the trim for you.
Outside Corner Edges
If the edge of your shiplap butts up to a corner that turns into another room, your best option is to use corner trim.
It’s a great way to finish the edge and conceal any gaps. Make sure to measure the angle since not all corners are exactly at a 90-degree angle.
Finishing Shiplap at Ceilings & Floors
Ensure your shiplap seamlessly integrates with your ceilings and floors by using crown molding at the ceiling and baseboards at the floor.
These elements not only cover any gaps but also add a polished look to the overall installation.
Different Trim Styles for Shiplap Edges
Experiment with various trim styles depending on your dƩcor preferences.
Wide flat trim gives a modern look, while decorative molding can add a classic touch to your room. Choose the design style that best suits your homeās aesthetic.
How to Finish Accent & Half-Shiplap Walls
Accent walls and half walls with shiplap can be beautifully finished with a cap trim piece at the top.
This adds a clear end point and enhances the overall look of the partial installation.
Troubleshooting Common Shiplap Edge Mistakes
Avoid common mistakes such as uneven edges or excessive caulking.
If gaps appear after initial installation, additional caulk can be applied carefully and smoothed out to maintain a clean line.
