Medallions are made to match the thickness of your flooring. Before you order yours, use a hole-saw or chisel to cut out a small piece of flooring from the spot where the medallion will be, and send this piece to the medallion maker. Flooring that's thinner than ⅜ inch can't accommodate a solid-wood medallion.

Using 1-inch painter's tape, make a rough approximation of the template's shape. Lay the template on the tape, and mark it by running a pencil around the template's inside edge. Place a magnetic nail finder where each floor joint crosses the pencil line. If you detect a nail, adjust the template location and repeat the process until the line is mostly nail-free.

Rout a Circle

Using double-stick carpet tape, secure the template on the pencil line. Chuck a ½-inch template bit with a top bearing into a router, and run it clockwise around the inside of the template. Start with a 1/16-inch-deep pass, then increase the depth by 3/16 inch for each pass until the bit reaches the subfloor. If you hit a nail, pound it down with a nailset.

Check the Subfloor

Check the Subfloor

Pry up the flooring inside the routed groove, then remove the template and tape. Make sure that the subfloor is flat and even by laying a straightedge across the cutout and sliding a piece of scrap flooring underneath. If necessary, smooth the subfloor with 40-grit sandpaper and a random-orbit sander.

Spread the Adhesive

Spread the Adhesive

Use a 3/16-inch V-notch trowel to comb wood-flooring adhesive evenly over the subfloor. Peterson prefers Bostik's Best moisture-cure urethane for its strong grip, low VOCs, and flexibility. If this adhesive gets on the floor or your hands, wipe it up with a cleaner, such as Bostik's Ultimate adhesive remover.

Drop in the Medallion

Drop in the Medallion

The trick here is to set the medallion in the cutout vertically, without any sideways tilt; an assistant with strong fingers will be invaluable. Once it's in place, tap it flush with the surrounding floor, using a scrap of wood to prevent marring. When the adhesive cures, the medallion can be finished, if needed.
