How to Install Crown Molding Like a Pro

Does the thought of installing crown molding make you break out into a cold sweat? The angles, the cutting, the joints! It’s enough to make any do-it-yourselfer run for the hills.

The good news is that crown molding is a task that even a novice do-it-yourselfer can tackle. All it takes it patience, time and a steady hand.

Here are some tips which will help prepare you for your first crown molding installation:

1. Be prepared to work overhead. Enlist the help of a friend to hold the molding while you nail it into place. If your ceilings are high, consider renting scaffolding equipment to eliminate the need to teeter on a ladder. Otherwise, make a solid, raised platform off of which to work. You can accomplish this by using a long plank that is anchored on either end by buckets.
2. Take measurements of your room and add at least 10 percent for waste and mistakes.
3. Select your crown molding. Your local home improvement center will likely carry a nice selection of crown molding in various styles and finishes. When selecting your crown molding, aim to compliment the architecture and style of your home.
4. Paint or stain your crown molding ahead of time. Some crown molding is already primed and ready to paint. You may also want to simply stain your crown molding, as well. Hardwoods, such as oak and walnut, accept stain nicely, while others, such as cherry and maple, may need a sealer before staining to prevent uneven coverage and blotches.
5. When selecting your crown molding, purchase the longest lengths available, as this will eliminate excessive seams.
6. Purchase or rent an electric or manual miter saw, as well as a coping saw and a utility blade for your job.
7. Cut all ends that converge at a 45 degree angle so they overlap and provide a nicer seam. You may still need to caulk any gaps, particularly if your walls aren’t straight.
8. When designing your layout, try to position your joints on top of studs to provide a secure place on which to anchor the molding to the wall. You may also choose to attach ¾-inch plywood to the wall, as this will provide a base onto which to secure the crown molding.
9. Drill pilot holes to keep the molding from splitting, and use 6d or 8d nails to anchor the crown molding to the wall. Countersink the nails with a nail set and putty the holes for a smooth finish.
10. To make coped joints, cut the molding at a 45-degree angle and then make a 60-degree angle back cut along the edge with a coping saw. You can then use a utility knife to trim any excess material for a snug fit.
11. The outside corners are typically the most difficult, as they must be compound mitered so that they slope toward the corner. Make your cuts first and then use your utility knife to perfect your joints.
12. Sit back, relax and admire your hard work!
