How to Install a Ceiling Medallion Around a Chandelier

A new chandelier often reveals an ugly ring of old paint, a cracked plaster patch or a hole that is bigger than the canopy can hide. A ceiling medallion covers all of it and makes the fixture look as if it was always meant to hang there. The catch is that most people glue one up with the light still attached, get it off centre, and then find the canopy no longer sits flat.

I fit chandeliers for a living and put up a ceiling medallion on perhaps one job in four. This is the order I work in, the sizes that look right, and the one electrical detail almost every online tutorial skips.

Choosing the right ceiling medallion size

A medallion that is too small looks like a bottle cap; one that is too large swallows the fixture. The rule I use is that the medallion diameter should be about one third to one half of the chandelier's width. For a 24 inch (61 cm) chandelier, that means a medallion between 8 and 12 inches (20 to 30 cm). For a heavy crystal piece or a high ceiling over 10 feet, go toward the larger end.

Check two more measurements before you buy:

• Centre hole. It must be smaller than the fixture canopy so the canopy can cover it, but large enough to pass the mounting bracket and wires. Most canopies are 4.5 to 5.5 inches across, and most medallions come with a 1.5 to 3 inch hole you can enlarge.
• Thickness at the centre. Many medallions are 1 to 2 inches deep at the edge but only half an inch or less at the hub. This matters for the electrical box, covered below.

Polyurethane medallions weigh a few ounces, cost $20 to $120, and are by far the easiest to install. Real plaster ones look beautiful but weigh several pounds and need screws into a joist, so they are a job for an experienced fitter.

Tools and materials

• Non-contact voltage tester
• Stepladder rated for your weight plus tools
• Polyurethane construction adhesive or the adhesive recommended by the medallion maker
• Four to six finishing nails or small trim screws
• Paintable acrylic caulk
• Pencil, tape measure and a utility knife or jigsaw for enlarging the hole
• A box extender ring, if the medallion adds depth at the centre

How to install a ceiling medallion step by step

1. Kill the power and take the fixture down

Switch off the circuit at the breaker, not just the wall switch, then test the wires with a voltage tester. Support the fixture while you disconnect it. A chandelier hanging by its wires is how ceiling boxes get pulled loose.

2. Paint the medallion first

Prime and paint it on a table, with two coats of ceiling paint or a contrasting colour. Painting overhead after installation leaves drips in the carved detail and takes three times as long.

3. Dry fit and mark

Hold the medallion up with the wires threaded through the centre. Rotate it until any pattern lines up with the walls or the dining table. Draw a light pencil line around the edge. If the hole needs enlarging, mark it now and cut it on the ground.

4. Glue and fix

Run a bead of adhesive in a ring about an inch in from the outer edge, plus a smaller ring near the centre. Press it up to your pencil line. Then drive four to six finishing nails through the thicker parts of the design into the ceiling, angled slightly toward the centre. The nails hold it while the adhesive cures, usually 24 hours.

5. Caulk the edge

Run a thin bead of paintable caulk around the outer edge and smooth it with a wet finger. Fill the nail holes too. Once dry, touch up with paint.

6. Rehang the fixture

Mount the bracket to the box, connect the wires and lift the canopy into place. It should sit flat against the medallion hub with no gap.

The box depth problem most guides ignore

Electrical codes in most countries require the front edge of a ceiling box to be flush with, or no more than a small distance behind, the finished surface. Once you add a medallion, that surface is the face of the medallion, not the ceiling. If the hub is half an inch thick, your box is now recessed half an inch, and the mounting bracket may sit too high for the canopy screws to reach.

The fix is a box extender ring, which costs a few dollars and screws onto the existing box to bring its edge forward. It also keeps the connections enclosed in a fire rated box rather than a hollow in the foam. If the fixture is heavy, confirm that the box is rated for fan or fixture support before you add anything. Our guide to telling if a chandelier is too heavy for your ceiling walks through that check.

Why I do not trust adhesive alone

A common shortcut is to stick a lightweight medallion up with adhesive only, because it weighs so little. I have taken down too many that had slowly sagged at one edge to recommend it. Ceilings move with temperature and humidity, older paint layers peel away from plaster, and adhesive bonded to flaking paint fails no matter how strong the glue is.

Four small nails take two minutes and remove that risk entirely. If the ceiling paint is chalky or peeling, scrape the area inside your pencil line back to a sound surface before gluing. That step matters more than the brand of adhesive.

Getting it centred over the table

A medallion makes an off-centre light more obvious, not less, because the eye now reads a clear circle on the ceiling. If the box is not where the table sits, fix that before the medallion goes up. You can move the box, or use a swag hook to offset the chandelier. Our article on hanging a chandelier when the ceiling box is off centre covers both options. Once the position is right, check the drop as well, using our guide to how high to hang a chandelier over a dining table.

If you are unsure about anything in the electrical steps, book a licensed electrician. Fitting the medallion itself is decorative work any careful person can do; the wiring is not.

Frequently asked questions

Do you need a ceiling medallion for a chandelier?

No, a chandelier works perfectly without one. A medallion is decorative, but it is very useful when the ceiling around the box is damaged or the old fixture left a mark. It also gives a small or plain chandelier more presence in a tall room.

Can you install a ceiling medallion without removing the light?

Some medallions are split into two halves so they can be fitted around an existing fixture. The seam usually shows unless it is filled and painted carefully. For a one piece medallion you must take the fixture down, and you need to do that anyway to fit a box extender if one is required.

What glue is best for a ceiling medallion?

Use a polyurethane construction adhesive or the specific adhesive the manufacturer recommends for polyurethane mouldings. Avoid hot glue and general craft glues, which soften in summer heat. Always back up the adhesive with a few finishing nails.
