All trimwork can be installed in bathrooms, as long as the moulding is properly sealed and painted, and as long as it is not being bombarded with water directly. A better solution is to use a compound miter saw which makes it possible to cut these complicated angles simply by setting two pre-marked guides on the tool. To form the angles required to install crown molding, the wood must be cut in two directions at once. Polyurethane molding is affordable, easy to install and resistant to warping, scratching and rotting. If varnishing, it is a good idea to go over the molding lightly by hand with fine sandpaper (220 or 330 grit) to remove any bumps caused by dust getting into the finish.
The molding is upside down, meaning the edge against the vertical fence is the bottom of the molding and the edge against the table is the top of the molding (think of your table as the ceiling). Our 4 5/8″ crown was too tall to fit under the blade of our Ryobi 10″ compound miter saw. Square-cut the first length of crown molding, push it tight into the corner and nail it in place.
Instead of nailing crown molding to the framing (the studs, plate, and joist), attach it to a nailer-a piece you attach to hold your nails. Once satisfied with the fit of the 1x4s, lock the blade angle in place and make a compound-angle cut into one of the lengths of crown. Note — Inside molding — You will always be able to see the saw cut, and the pointed end will always be at the bottom of the crown molding.
The seams blend in perfectly after you caulk and paint over them, so don’t worry if you can’t find a single strip of molding long enough. Chapter 4 in our new 2nd edition book deals with installing crown molding on a horizontal ceiling. The type of bead-board wainscot paneling I’m showing here is so easy to install it’s not even funny! You can obtain the miter and blade tilt from the Compound Miter Chart, Crown Molding Table or the Compound Miter Excel Program. Cut from the corner to the point where the cove begins, following the groove you cut in step two.
I forgot to mention also, that the coping helps with the fact that much like the walls aren’t always straight, the corners aren’t always perfect 90 degree right angles either. Since stain can’t be applied over the primer, this type of crown molding is unsuitable for a stain-and-varnish project. With this method, the crown can be cut while laying flat on the table because the blade tilts to the necessary beveled position instead of having to prop the board up manually. Rushing, especially rushing the cutting, is only going to provide lots of expensive molding scraps for the scrap pile.
Another tool that will make the job easier is a power miter saw (Image 3). It’s accurate and makes a cleaner cut than a plastic miter box. Today, thanks to a new molding material, you can create the same effect with less skill than it takes to install wood molding. To avoid cutting the molding too short, always used the most extreme point as the reference point. Again, the advantage of the backer board is that you can now nail the crown at any point along its length. The joint at an outside corner is formed by two simple miter cuts, but making them fit takes several steps (Photos 16 – 18). Our crown molding can be painted before installation; it makes the job much easier.
When measuring walls at inside corners it can be hard to know exactly what point to use as the reference point. Here’s a straightforward step-by-step approach—accompanied by a few tricks of the trade—to help even novice DIYers put up crown molding like a pro. Once the crown starts flipping around, the X shows me which is the bottom right. The second piece will be cut at a 45º angle as before, but then coped so that it fits snugly over the profile of the first piece. With this setting the right-inside and left-outside corners, pieces C and D, can be cut.
One kit will make 12 inside corners and 2 outside corners, however there are no corner pieces. Our Decorative Projects page shows you examples of some window and door cornices, fireplace mantels, crown molding shelves, birdhouses and flowerpots that you will be able to build. Since then, I’ve put it in eight or 10 rooms, and around half a dozen bookcases and cabinets. After a few more exhales, we got smarter and pre-drilled even more holes in the crown before we held it in place.
I recently completed a crown molding project for my dining room and it really added a finishing touch to the room. It’s easier to work with short pieces and make trial-and-error cuts if necessary to get a tight fit in each corner than to attempt to make longer lengths meet precisely. When you cut window and door casing, you typically place the back of the trim on the table surface.
Use a good-quality finishing blade with a minimum of 40 teeth, though 80 teeth is preferable since the more teeth a blade has, the cleaner the cut. Now if the crown is small enough, say about 1½ to 3 inches wide, you can usually get a tight fit against the ceiling by only nailing into the wall studs. In most cases, the construction adhesive will provide enough tack to hold the lightweight molding in place as it dries.
Since crown molding is generally made of wood, it is prudent to let it sit in the home environment for a few days before installing it. The wood will expand or contract based on the temperature and humidity in the house; it is better to let it adjust before nailing it in so that it will not crack and warp after the fact. Then I adjust the saw to make an opposing miter cut-at the same angle-into the end of the mating piece of crown.
What’s really nice is that you don’t have to remember that – it’s printed right on the jig (along with the orientations for left inside corners and both outside corners). Before installing crown molding, it is a good idea to pre-finish it. For painted molding, this means applying primer and one finish coat. You can skip the miter and coping cuts altogether by using corner blocks, which will prevent having to cut angles into the molding. Cut the return with a matching outside corner using a short piece of leftover molding.
The advantage to using some of those jigs (I have a different one but it works pretty well) is that you will be coping the crown instead of mitering it. Generally this is considered a superior joint for trim work. Right on. One of the first things I do when doing crown is cut a small mock-up of an outside corner so I can test fit it on all outside corners and see where adjustments of the angle need to be made. Put the crown upside down, glue, then clamp across the joint while shimming till you get a perfect joint. When installing crown molding with block corners, the blocks need to be installed first.
To glue the corner shift the molding to expose the end and use a small brush to apply a coat of wood glue to both pieces. The first time I installed crown molding, I probably wasn’t really installing it at all-I was just handing my dad tools off the truck. Installing crown moulding takes patience and considerable skill; the moulding is positioned at an angle on the wall, and each joint is made up of compound angles. To make their cuts, they angle the molding on the saw as if it was sitting against the wall and ceiling and make a 45 degree cut, like this…. Generally, the part of the moulding that has the largest cove profile is the top.
With the bottoms down, slide them both into the corner and make minor adjustments until you have a perfect fit (no gaps). Crown molding is the decorative trim used to smooth out edges between wall and ceiling, giving each room a much more elegant and warm look and feel. Leave the board on the table after making the cut to measure and mark the opposite end to cut corner A.
Master Bedroom Door Trim Detail with led lights tucked inside…. forget door trim, crown molding with row lighting! If people want crown they should get it and not be swayed because of some other person’s person opinion on how it looks. Place the top of the crown molding face up, flat on the table, with the top of the crown moulding next to the fence and make the cut.
After applying a little wood glue to the joint, I slid the second piece of crown into position and nailed it to the backer board. Cut the two ends with the appropriate angles and glue the mating edges of the scarf joint just before installing them. It’s easy to install an elaborate cornice when you work in layers, and the end result will add a bold statement. Once all the crown molding is installed all the nail holes need to be filled flush with wood putty If there are any gaps, they will need to be filled with a small bead of caulking If the crown molding is going to be painted and stained, caulking can only be applied where the molding contacts the wall or ceiling, not in the corners.
Our trick comes in very handy as you learn how to install crown molding on cabinets, and you’ll find lots of other uses for it when you’re assembling furniture projects. I cut the first length of crown with a square end, pushed it tight into the corner and nailed it in place. Check out our customer Testimonials page to see how easy and simple our products are to use and how they can save you from insanity while trying to install crown molding.
To get the angle right, use scraps of crown and the method shown in Photo 3. Draw a slash mark on the crown to indicate the direction of the miter cut. Nailing crown in place will be much easier with the use of a pneumatic nail gun These tools will drive and sink the nails, all in one easy motion. Yeah, 4×4’s give me a little bit of a problem but I just turn them over and finish the cut that way.
