How to Install Chair Rail Molding

Chair rail molding is a horizontal strip of molding installed on the wall at roughly chair-back height (typically 32–36 inches from the floor). Originally designed to protect walls from chair backs, it now serves primarily as a decorative element that divides the wall into two zones — creating opportunities for two-tone paint, wainscoting below, or wallpaper above. Here's how to install it.

What You'll Need

• Flexible peel-and-stick molding trim: 32.8ft Flexible Peel and Stick Molding Trim, White
• Miter saw: SKIL 10" Dual Bevel Sliding Compound Miter Saw
• Brad nailer: Metabo HPT Brad Nailer 18 Gauge NT50AE2
• Finish nails: Mr. Pen Nail Assortment Kit, 600 Pcs
• Stud finder: Stud Finder Wall Scanner 5-in-1
• Laser level: Laser Level Line Tool by AikTryee
• Construction adhesive: Loctite PL Premium Construction Adhesive
• Caulk gun kit: Professional Caulk Gun Kit 5-in-1
• Silicone caulk: GE Advanced Silicone Caulk, Clear
• Wood filler: BONCART Wood Filler White, Paintable
• Painter's tape: ScotchBlue Original Painter's Tape

Step 1: Determine the Height

The standard chair rail height is 32–36 inches from the floor. In rooms with 8-foot ceilings, 32–33 inches looks most proportional. In rooms with 9–10 foot ceilings, 36–40 inches works better. Measure up from the floor at multiple points around the room — floors are rarely perfectly level, so use the laser level to establish a perfectly level reference line at your chosen height.

Step 2: Mark the Studs

Use the stud finder to locate all wall studs at chair rail height. Mark each stud location with a light pencil mark just above where the molding will sit. Nailing into studs is essential for a secure installation.

Step 3: Cut the Molding

Use the SKIL miter saw to cut the chair rail pieces. Inside corners get 45-degree miter cuts (or cope joints for a tighter fit). Outside corners get 45-degree miter cuts in the opposite direction. Straight runs get square cuts. Cut test pieces in scrap first to verify your angles.

Step 4: Install the Molding

Apply a bead of Loctite PL construction adhesive to the back of each piece. Align the top edge with your laser level reference line and press firmly against the wall. Nail with the Metabo HPT brad nailer using finish nails into every stud. Work around the room in sequence, fitting each piece before cutting the next.

Step 5: Fill, Caulk, and Paint

Fill nail holes with BONCART wood filler, sand smooth, and caulk all edges with GE silicone caulk. Apply painter's tape and paint the molding with semi-gloss white. Once the molding is painted, paint the wall above and below in your chosen colors.

Design Ideas for Chair Rail

• Two-tone paint: Paint the wall below the rail a darker color and above a lighter color for a classic, elegant look.
• Wainscoting below: Add wainscoting panels below the chair rail for a formal, traditional style.
• Wallpaper above: Install wallpaper above the chair rail for a bold, decorative statement.
• Beadboard below: Install beadboard paneling below the chair rail for a cottage or farmhouse look.

Pro Tips

• For a quick, no-cut option, use flexible peel-and-stick molding trim — just peel and press at your marked height.
• Use a laser level rather than a chalk line — it's faster, more accurate, and leaves no marks to clean up.
• Caulk all edges before painting — it makes the molding look like it grew out of the wall.
• In dining rooms, position the chair rail to align with the top of your dining chairs for the most authentic look.
