Moderately Challenging

Instructions

Things you need

  • Baseboard trim
  • Table saw
  • Pencil
  • Finish nails
  • Hammer
  1. 1

    Measure the area where you need to add new baseboards. Remove the old baseboard material you are replacing.

  2. 2

    Select baseboard trim material to match the originals. Mark where the cuts need to go and use a table saw to slice into them in the right place.

  3. 3

    Lay the baseboard material to within an inch of the rounded corner. Take a piece of baseboard material and cut it to measure 2 inches in length at 22 1/2-degree angles on both ends. You should be able to butt them up against the straight piece, if cut at the same angle.

  4. 4

    Place the smaller piece so that they angle around the curved corner perfectly. While your baseboard is only a close cousin to being rounded, it will create the illusion of the round edge you are after.

  5. 5

    Attach the baseboard firmly with finish nails. Add a small amount of caulking to fill any gaps left where the pieces meet. Paint the replacement materials to match the original baseboards.
