If you’re the type of do-it-yourselfer that is willing to try most any small renovation at least once, provided of course the potential for injury or loss of home due to fire or flood is kept to a minimum, then at some point in time you’re probably going to attempt to install a crown molding.
For the uninitiated, a crown molding is the decorative trim used to elegantly bridge the harsh corner between your interior walls and ceiling. Is the crown molding a necessary part of a home’s finishing? No. However, will a home be all the better for having crown moldings, providing an upscale setting, allowing you to host guests and dignitaries somewhat above your normal social status? Very likely. So, for the décor value, as well as the potential to expand your guest lists, thereby elevating the conversation of your gatherings beyond such subjects as to whether Mankind really deserved the win over The Undertaker in WrestleMania 13, we install crown moldings.
Basic tools for the job will include a 10 inch chop saw, and an air-compressor type of finishing gun. Because your crown molding will most likely be painted, and as a result made of MDF (medium density fiberboard), you’ll require the power and blade count (at least 60 carbide teeth) of a 10 inch blade, along with the superior performance of an air gun. Don’t attempt to pre-drill and install a crown molding with finishing nails. Finishing nails are fine for pine and real wood moldings because real wood, even when dry, maintains some of its elasticity. MDF material, on the other hand, is simply too hard, and offers no forgiveness, causing the amateur carpenter to make a mess of the molding’s surface when countersinking the finishing nail.
Considered the most challenging finishing molding to install, due to the crowns two beveled edges needing to be placed squarely against the wall and ceiling, there are strategies to installing this molding correctly. As a precautionary measure, and before loading the car up with tens of moldings, be sure to purchase the two following items. One, an 8 ft. piece of the crown molding of your choice, and two, an “OGEE” cutting guide. Once at home, carefully remove the OGEE cutting guide from its box (because you may have to return it) and read the how-to instructions. Finishing carpenters each have their own type of wooden jigs or strategies when it comes to holding a crown molding in place as they cut it. The OGEE guide is simply a plastic version of one of these jigs, and safely sets the crown molding in position under the saw for the amateur finisher. The 8 ft. length of molding is basically a 10-12 dollar research and development expense into whether you’re capable of performing this task or not. Because the crown molding sits on an angle, has beveled edges, and must be further cut at 45 degrees, all while being positioned in an upside down manner for at least half of the required cuts, the directionally challenged person is going to find this experience frustrating.
So, read the OGEE guide’s instructions, take your 8 ft. molding, and try a few left and right hand, inside and outside corner, practice cuts. Then, using these short lengths of moldings, see how they fit up into the corners of where the wall meets the ceiling. Once you’ve established what an inside left corner cut is, as well as an inside right, and any right or left outside corner cuts, label these short pieces with a marker. These “pre-cuts” will be a great help in directionally guiding you when it comes to cutting the longer lengths. On the other hand, if after cutting an entire 8 ft. crown into bits and pieces you still can’t get the hang of it, don’t despair, some people can perform open heart surgery, then can’t figure their way out of a round-a-bout, it’s just what is.
