Crown molding accents the colors and the dimensions of any room. It is fairly easy to install if your ceiling is flat, but adding this feature on sloped surfaces can be challenging. Here's how to get it done.
Before you purchase your molding, figure out exactly how much you need. Precisely measure every surface. Do not just estimate—if you have a lot of measurements, those extra inches could add up to more than you realize.
Purchase Your Molding
Home improvement stores offer crown molding in a variety of styles and materials. Make a decision based on your budget and tastes. Select carefully, as this molding will likely last the lifetime of the house.
Buy more than you need. This will be handy in case you make mistakes while cutting, but also if you need to make replacements down the road. The exact molding you buy now may not be for sale in a few years' time.
Use a Miter Saw
Use a miter saw to cut the molding to the length of your measurements. Your ceiling will probably be sloped around 45 degrees, so cut the moldings at that angle where they meet that slope. Be careful: a poor cut will make the job look sloppy and the molding won't fit properly.
Attach the Molding
Once you have cut the molding, hold it in place and gently drive finishing nails into the walls. Try not to miss the nail and hit the molding, because you will damage it. Make sure it fits flush with the wall and ceiling.
Fill the Nail Holes
Complete the look with spackle in the holes where your nails are. This should make a smooth and even finish for your new molding.
