How to Terminate Crown Molding

Terminating at a corner

• 1

  Mark the crown molding with the pencil, at the length needed to run completely to the corner.

• 2

  Secure the molding in the miter saw with the back flat against the miter saw's rail. The pencil mark should be right at the saw point.

• 3

  Saw the molding at a 90 degree angle and remove it from the miter saw.

• 4

  Mount the crown molding in place with the flat end right at the corner. If the molding is too long, use the sanding block to shave a little length off the flat end.

Terminating at a room transition

• 5

  Secure a scrap piece of molding in the miter saw, with just over the width of the molding past the cutting spot.

• 6

  Cut the molding at a 45 degree angle towards the end. This should make the back of the molding shorter than the front.

• 7

  Slide the molding down until 45 degree cut is a hair past the cutting spot.

• 8

  Cut the molding at a 90 degree angle to create a small triangle with the molding's contour on one side.

• 9

  Cut molding running up to the transition short of the end point by the width of the molding using the miter saw and at a 90 degree angle. This will allow for space to place the small triangle before the transition.

• 10

  Mount the long piece of moulding running up to the transition.

• 11

  Mount the triangle piece of molding at the end of the long piece so the contour of the molding is on the outside and the flat sides are against the wall and the molding. Typically this piece will be glued, rather than nailed because its size makes it difficult to nail without destroying it.
