How to Cut the Angles for Inside Corner Baseboard Molding

Save

When trimming out a house, baseboards are used at the bottom of the wall to cover the joint between the sheetrock and the flooring material. A baseboard is a piece of trim molding, usually 3/4 or 5/8 inch thick, made from a solid piece of wood for staining, or from multiple pieces of wood for paint-grade moldings. The do-it-yourself handyman can determine the angles for the inside and outside corner cuts if he knows a few tricks of the trade.

Things You'll Need

  • Tape measure
  • Pencil
  • Pneumatic finish nail gun
  • Finish nails
  • Miter saw
  • Coping saw
  • Hammer
  • Measure from one corner to the next corner of the room for the dimension needed to cut the baseboard molding. Use a tape measure.

  • Mark a piece of baseboard molding with this dimension. Use a pencil to mark the top edge of the molding.

  • Cut the baseboard at 90 degrees to the face of the baseboard. Lower the sawblade slowly through out the cut to help prevent splintering of the wood.

  • Nail the first piece of baseboard into place, using a pneumatic finish nail gun. Shoot the nails into the bottom plate to secure the baseboard.

  • Adjust the miter saw to the 45-degree mark and lock it into place. Cut the end of the baseboard at 45 degrees.

  • Back-cut the miter cut you just made on the baseboard with a coping saw. The saw is used to cut the profile at 45 degrees in the opposite direction. This leaves a knife edge of a profile that fits into the flat face of the other piece of baseboard, making a tight-fitting joint.

  • Tap the end of the baseboard into the corner and mark the other end of the baseboard with a pencil for the next cut. Use a hammer for this step.

  • Repeat steps 2 through 6 for the remaining inside corner baseboards cuts.

Tips & Warnings

  • Wear kneepads while installing baseboard molding.
  • Wear safety glasses when using the miter saw.
