Could you please describe the damage of the crown molding? How much of the corner is gone, and if you can also let me know what area or how old of the molding is.
Also is there any kind of designs on the molding?
Good morning (Customer) Your best solution for this repair is to use an epoxy filler. A particularly good one for this situation is brand name Bondo. Readily available at the home improvement stores. You will be able to fill in the damaged area quite easily with the paste like material. Do this with a disposable putty knife, also at the same place you pick up the epoxy. The slight decorative grooves can be matched fairly closely by just dragging your putty knife or other tool to recreate the design. It won't be perfect at this point but later when the epoxy has hardened you will sand it down to a smooth and matching finish. Painting is the final step.
