How to Install Foam Crown Molding
TOH technical editor Mark Powers demonstrates how to install "easy" crown molding
Crown molding makes it to the top of most remodeling lists because it adds charm and value to a home, not because people enjoy spending a Saturday trying to get the corners just right. Luckily, there's a simple way to beat miter-saw frustration. Trimroc molding from Canamould Extrusions is a lightweight polystyrene foam coated in hard plaster. It cuts smoothly with a handsaw, and, as This Old House senior technical editor Mark Powers shows here, it goes up in a flash with joint compound. No coping, no tricky angles, and ragged joints disappear with a dab of mud. So in just a weekend, you can upgrade a plain room to an elegant space—and still leave plenty of time for the rest of your list. Watch the video above to learn how to install foam crown molding.

Lay Out and Cut the Molding
If you're working with walls that are out of level and plumb, allow your eye, rather than a level, to guide the position of the molding. For best results, focus on getting the crown to look parallel with any neighboring trim. Install it starting at an inside corner and work toward any outside corners.
Hold a strip of molding in place above a door or window casing. Adjust the molding until it looks even with the casing (ask a helper to stand back and look for you). Draw a pencil line to mark this positioning so that you can install the crown at this alignment.
