Trim Molding Accent Wall

This project adds a striking focal point to a wall.

Difficulty: Intermediate (two people are suggested to complete this project)

3 pieces of chair rail trim in 12' lengths
Paint in desired color
Paint tray
¼" paint roller
Tape measure
Chop saw
12–24' extension ladder
Snap chalk
18-gauge pin nailer
1" 18-gauge finish nails
Wood putty

Preparing the Trim
  1. Line up a piece of the 12" trim against the wall where it will be placed. Use a pencil to mark the location. Use the protractor to determine the ceiling angle to cut the trim. (If your ceiling is not angled, don’t worry about this step.) Then measure the desired length of the trim
  2. Set the protractor to the measured angle from step 1, and use the chop saw to cut an angle on the trim

  3. Starting at the angled edge, measure the trim to the desired length from step 1 and mark with a pencil. Use the chop saw to cut at a straight, 180-degree angle at the marked location

  4. Repeat steps 2 and 3 with the other trim pieces

  5. Carpenter Tip: You can get the trim precut at any hardware store.

  6. Lay the trim pieces on a flat surface and paint. Don’t forget the use gloves!

  7. Designer Tip: Use a paint roller for the flat, wide surface and a 1" straight-edge paintbrush on the edges for a cleaner finish

  8. Let dry for 1 hour

  9. Putting Trim on the Wall

  10. Find the mark from earlier and place the vertical level on a leveled surface (the mantle or floor depending on where the trim is going) to make a line leading up to the mark

  11. Line up the snap chalk with the mark, and use the level to ensure it’s straight. Using your fingers, lightly pull the string back and release it so that it snaps back, hitting the wall. This will create the vertical line

  12. Repeat step 8 for each piece of trim

  13. Carpenter Tip: If snap chalk is unavailable, regular chalk and a straight edge to draw a line

  14. Line up the trim with the vertical line. Decide whether the trim will be aligned with the inside or the outside of the vertical line. Repeat for each piece of trim

  15. Using a ladder (if necessary) and a pin nailer, and starting from the top of the trim, secure two nails about ½" in from each edge. Repeat this step all the way down the trim, adding nails every 12"

  16. Once the nailing is complete, put wood putty over each nail, letting it set and dry per the manufacturer’s instructions. Once dried, use paint to cover the wood putty

  17. Use the small paintbrush to paint along the edges of the trim

  18. Once the edges are painted, use a roller brush to cover a wider area. Using an extender will help you paint hard-to-reach areas

  19. Designer Tip: The color of the trim doesn’t have to be the same color as the middle. You can mix and match colors to your liking. After all, it is your house!

  20. Let dry and enjoy the new focal point of the room
