Building a wood slat wall lends a refined air to a room. It's a mid-century modern–esque look often found at high-end hotels or designer homes. It's not a feature you ordinarily see in homes—which makes it even more noteworthy. A wood slat wall is the ideal focal point for a room: an accent wall that you'll have for years to come.

Building a DIY wood slat wall can be a bit time-consuming, but it isn't complicated at all. Plus, you have a couple of options. One method, using dimensional lumber slats, is easier but more expensive, while the other method—which uses sheet good slats—takes more time but saves on costs.

This guide will yield enough slats to cover 8 feet of wall—plan to add more wood and supplies as needed to cover the space you're working with.

Basics of Building a Wood Slat Wall

A wood slat wall is made of vertical strips of wood that extend from the floor to the ceiling. Each strip is 1/2 to 2 inches wide. Width is your choice, depending on the final look you're hoping to achieve.

To avoid a zebra-stripe effect, spaces between the slats should be less than the width of the slats, So, 1/2-inch slats should be spaced 1/4 inch apart.

The color of the wall behind the slats plays an important role because it's the background for the slats. You may want to choose a dark background, such as matte-black, for a dramatic, modern look.

Dimensional Lumber Slats
  • One-by-two lumber strips

  • $150 to $300 per 8 linear feet

  • Requires a miter or circular saw, not a table saw

  • Faster process

  • Thicker wood slats

Sheet Good Slats
  • Large sheets of plywood that you cut into slats

  • $40 to $60 per 8 linear feet

  • Requires table saw, plus miter or circular saw

  • Time-intensive

  • Thinner wood slats

Building With Dimensional Lumber

Using pre-cut, one-by-two wood strips accelerates the project and helps you avoid having to use a table saw. With this method, most of the work is concentrated on cutting the ends of the boards and nailing up the boards.

Each one-by-two is actually 1 1/2 inches wide. To cover an 8-foot stretch of wall with a 3/4-inch space between boards would require 48 strips. While softwood strips are inexpensive, the slat wall can still be rather pricey when you need to buy 100 or 200 strips. Hardwood strips are three times more expensive than softwood but require less finishing work.

Building With Sheet Goods

Cutting a 4-foot by 8-foot sheet of plywood into strips is a more cost-effective approach, but it is more time-intensive. One sheet of plywood yields around 90 to 92 strips, each 1/2 inch wide.

One chief difference between using sheet goods and dimensional lumber is thickness. If you'd like slats that hug the wall closely, you'll want to use nominal 1/2-inch plywood (about 3/8 inch thick). With dimensional one-by-two lumber, the strips would be 3/4 inch thick.

Safety Considerations

Working with a table saw or circular saw is hazardous enough but even more so with repetitive cutting. Stay alert at all times. Keep your hands away from the blade by pushing from a distance or by using a push block or push stick. Large sheets can be difficult to push through a table saw, so do the cutting with an assistant to help hold the other end.

Tip

You can cut the sheets in half lengthwise with a circular saw to start to make the pieces easier to handle on the table saw.

What You'll Need

Equipment / Tools

  • Table saw
  • Electric miter saw
  • Cordless finish nailer
  • Eye and hearing protection
  • Putty knife
  • Heavy gloves
  • #220 grit sandpaper
  • Laser level
  • Tape measure

Materials

  • Plywood sheets or dimensional lumber slats
  • Black matte interior paint
  • Wood filler
  • Construction glue

Instructions

  1. Plan Wood Slat Wall

    Calculate how much wood you need to buy based on strip and spacing width. Unless you plan on moving light switches or outlets, the wood slats need to work around them. Plan for about 1/2 inch of space around the faceplates.

  2. Paint the Wall

    Paint the wall the intended color, for a contrast with the wood slats. Roll out the paint with two coats. Matte or flat paint dries quickly, so you can apply the second or more coats within 30 to 45 minutes.

  3. Cut Wood Slats

    Run the plywood lengthwise through the table saw to cut 1/2-inch-wide slats or your desired width. Periodically check strip width to make sure that the width is uniform, as the saw gate may loosen over time. If you are using pre-cut dimensional lumber slats, skip this step.

    Tip

    Experiment with slat-width and with the spacing between the slats to find the perfect combination that suits your tastes.

  4. Fill Large Voids

    In some places, the sides of the plywood may exhibit small voids or holes. Using the putty knife, fill these in with wood filler.

  5. Sand Wood Slats

    Wearing heavy gloves, sand each wood slat individually. Cup the sandpaper in your hand and lightly run the slat up and down to remove stray splinters. The layered sides of plywood do not sand down smoothly, so try to remove the roughest areas.

  6. Paint or Stain Wood Slats

    Lay out the wood slats. Paint or stain the front and both sides of the wood slats (but not the back).

  7. Install Wood Slats

    Run a bead of construction glue down the length of a slat, on the back side. Begin in a corner and install the first wood slat. Position it vertically with the laser level's plumb feature or with a bubble level. Nail it in place. Use one of the slats held on-edge as a spacer for the next slat, or use blocks cut to your spacing size to butt against the previously installed slat to keep spacing uniform across the wall.

    Since you'll be nailing most of the slats into drywall, angling the nails will help hold the slat in place better while the glue sets.

    Tip

    Keep the beads of glue narrow and on-center to avoid squeezing out excess glue after the slats are nailed to the wall.

  8. Cut Around Obstacles

    When you reach an obstacle, use the miter saw to cut the slats around it.

  9. Fill Nail Holes on Slats

    After all of the slats have been installed, fill the nail holes with wood putty.

  10. Touch up the Slats

    With a brush for paint or a rag for stain, touch up wood slats as needed.
