How To Install a Chair Rail

Chair rails can be a fun and rewarding item to install in your home. They can range from simple to highly extravagant but either way it adds a touch of class to any room or living space, and is also really fun to install.


  • Pneumatic Finish Nailer, 15 gauge
  • Air compressor and air hose
  • Miter box and saw
  • Tape Measure
  • Level
  • Caulk
  • Caulking Gun
  • Sandpaper
  • Primer
  • Paint
  • Pencil
  • A buddy


  1. The first thing that you have to do is to choose what style of moulding you want to install.
  2. Choose what height you would like the railing to sit at, the common heights for chair rails fall between 32" and 35". Take your pick and then go around the room marking on the wall the height that you chose.
  3. Start by cutting the first piece of moulding square, and holding it against a flat surface such as a door casing.
  4. Cut the CHAIR RAIL moulding at 45 degree angles on inside corners and outside corners so that you can conjoin 2 pieces of moulding seamlessly.
  5. Using your buddy and level, hold the first piece of moulding on the wall, and use your pneumatic Finish Nailer to shoot a nail on the underside of the piece. After you do that, move to the other side of the moulding, check to make sure that the piece is still level then shoot another nail on the underside. Go along the length of the piece and shoot nails about every foot and a half to two feet.
  6. After you have finished installing the moulding around the length of the room, sand any rough edges that may have occurred during installation.
  7. Take the caulk from your caulk gun and put a small drop on the holes caused by the nails, and smooth with your fingers.
  8. Prime and paint your new chair rail to your desired colour and your done.
