A slat wall is more than an elegant interior feature. It also adds warmth, depth, and rhythm to a room. The good news is that you do not need to be a carpenter or an interior designer to build one yourself. In this guide, we walk through the process step by step.
Tools and materials you need
Before you begin, make sure you have:
- slats in the wood species and dimensions you want
- spacers or spacing blocks
- a spirit level or laser
- a saw, ideally a miter saw
- a tape measure
- adhesive such as construction adhesive, or a brad nailer
- finishing supplies if you plan to stain, oil, or coat the slats
- a backer board if you want one
Tip: Use our slat wall calculator to estimate how many slats and how much linear footage you need before you buy materials.
Step 1: Measure the wall
Start by measuring the height and width of the wall you want to cover. Write the numbers down carefully, because they form the basis for the rest of the project.
Step 2: Plan the spacing
Standard spacing often falls somewhere between 10 and 30 mm, but this is also where you can shape the final look. Use spacers to keep the result even.
Remember that spacing affects both the visual rhythm and the number of slats you need, so it is worth testing different combinations in the calculator before you commit.
Step 3: Cut the slats to length
Use a saw with a good blade so you get clean, straight cuts. If the project includes multiple lengths, label the slats as you go.
Step 4: Fix the slats to the wall
Attach them either directly to the wall or to a backer board. You can use:
- construction adhesive for a cleaner look
- a brad nailer for quicker installation
- screws, although they may remain visible
Start from one side and use a level as you work so the slats stay straight.
Step 5: Finish the slats
If you want to stain, paint, or oil the slats, it is usually best to do that before installation, especially if you want to avoid visible transitions between the slats and the gaps.
Bonus: acoustic backing
For better acoustics, you can install the slats in front of a black felt backer. That gives the wall a more contemporary look while also reducing echo.
