Easy Ways to Cut Crown Molding for Corners

You might want a simple method to cut crown molding perfectly, so that it fits over the tricky corners of your ceilings where they meet the walls. By following a few easy tips, you can cut the moldings of the corners without much trouble, and give it a tidy look. Doing it yourself helps cut down on expenses that you could incur in hiring a contractor.

Tools and Materials Needed:

  • Crown Molding
  • Miter Saw
  • Measuring Tape
  • Putty or Wood Filler
  • Paint
  • Safety glasses

Step 1: Choosing the Cut Technique

The most popular and easy ways to cut the corners of moldings are either placing the molding upwards, and setting the saw angle in the desired manner, or cutting it by laying it down flat on the saw table and then fixing it up against the wall corner. Make sure that your miter saw is sharp, and chosen according to the size of the molding. For moldings more than 10 inches wide, you must use a compound saw. For anything less than this, the miter saw must be double the width of the crown molding.

Step 2: Measurements

The crown molding must be allowed to be at the room temperature for at least a day, so that the wood has time to expand or contract, based on the conditions in the room. Align the molding against the wall, in the same position as it is going to be attached to the wall, to check if it fits. Measure the dimensions of the room where the cut moldings are to be used. Double check the dimensions, since a simple mistake may cause you to have crown moldings that are not perfect for your corners. Mark the part where the corner is, so that when you place the tape to record the length and the height, there are no areas between them that go unmeasured. According to the size required, the moldings may need to be joined to similar other pieces with glue, to ensure that the entire area is covered.

Step 3: Deciding the Angles

Determine the angles for the corners. Generally a 45 degree angle is suggested. The miter saw has an in built set up for this degree and aids in making smooth cuts. After the first molding is cut, the next piece needs to be cut at a reverse angle.

Step 4: Cutting at the Outside Corners

Align the bottom part of the molding against the back side or plate of your saw. Position the saw base to cut the angle. Make sure the molding sits snugly on the saw plate and press it smoothly to the base. Switch on the power, and carefully cut the molding in a single stroke. The saw must be handled with care, and make it a point to wear safety glasses when at work. Keep some extra molding handy, so that you can practice before making the final cuts. Remember that for an outside corner, the top part of the crown molding must be longer compared to the lower part.

Step 5: Cutting the Inside Crown Molding Angles

If the 45 degree outside angle is cut for the outside corner, then the inner reverse angle should be of 45 degrees in the opposite direction. This too is marked on the miter saw. The inner corner angle must not exceed 45 degrees if the outer is 45 degrees as well. Repeat the cut in the same manner as in the previous step. Here the molding bottom must be of greater length than the top area of the molding.

If you see that the ceiling-wall meeting points have gaps after cutting the molding, use putty or wood filler to cover them up. It will give you immense satisfaction to see how well you have set up the crown molding at the corners all by yourself.
