How to Cut Foam Molding
Foam molding is manufactured for crown molding, baseboard molding and for other decorative projects. Cutting foam molding is just as difficult as cutting wood or MDF molding: Getting the angles right is usually the hardest part. You also have to orient the cut on the foam molding in the correct manner or things will not line up. If you have never cut molding, or any other kind of finishing product, make a few practice cuts before you make any cuts in the molding. This will help you understand cut placement and the orientation of the molding with the saw blade. There are three basic cuts you will have to make: a scarf joint, an outside 90-degree angle, and an inside cope joint. Does this Spark an idea?
