How To Install a Crown Molding – DIY Home Improvement Ideas

Crown molding is one of the trickiest moldings to cut and install. One of the basics rules is that you measure the wall normally from end to end, but you cut the piece up side down, which brings for some a lot of confusion and eventually some wasted pricey material 🙂

Preparations

1. Take the measurements, and then add 10 percent to the figures for when you make mistakes.

2. Choose the style and finish that you want. Many sizes and shapes are available for you to choose from. Make sure that they match with your personal preferences, the decorations in the room, and the overall color scheme. The finish that you choose should be applied first before you begin cutting and fitting the crown molding.

3. Buy the size that will need the least amount of splices. Splices may be unavoidable in some cases, but the fewer splices there are, the more appealing the end results will be.

Cutting The Corners

1. The first and most difficult part in learning how to install crown molding is cutting the corners. The easiest way to trim the corners is by using a coping saw, since a mitered joint is less tight than a coped joint. If there is any gap in a coped cut, this can be concealed with some caulk.

2. Another tool that you can choose to cut the corners is a power miter saw. Not only is it accurate, it also provides a cleaner cut.

Measuring and Marking the Wall

Take the measurements of the wall for the length of the very first piece of molding. You have to mark the wall so that it shows the bottom edge of the molding.

Cutting the Pieces

1. After determining the length of the molding, cut it in a straight line at a ninety degree angle. This will make both ends hit against the side walls.

2. Cut the next piece so it fits an inside corner. You can do this by moving the miter saw guide to the forty-five degree angle point and then setting the molding into place.

3. Know how the pieces fit together. The edge against the vertical fence is the bottom part of the molding while the edge against the table is the top. Imagine that your table is the ceiling.

4. Cut the molding at a perfect forty-five degree angle using a ten inch saw blade. For an inside corner, the bottom should be longer than the top. For an outside corner, the top should be longer than the bottom.

Coping the Joint

When you cope a joint, you have to scribe the end of one molding to the face of another. Mark the front edge using a pencil, and then with the help of a coping saw, cut as close to the line as possible. Be sure to cut at a slight angle.

Checking For Gaps

Any gaps that have to be trimmed will be revealed if the fit is checked against a scrap piece of molding. To get rid of these gaps, cut off the high points using the coping saw.

Attaching the Molding

The last part on how to install crown molding is attaching the molding. Take the molding to the wall once the fit is perfect. You will need some help holding a long piece. Attach it to the wall by pushing the end into the corner. Ensure that the fit is as tight as possible. If there are any gaps, cover them using a caulk gun. Use optional blocks to cover the spot where the outside corners should meet.

As much as I do encourage everybody to try the steps above, I advice to check it out first maybe on some free home improvement store lessons.

Good luck!
