How to Install Wood Rosettes

Jonah Morrissey

Wood rosettes add decorative detail to wood moldings. Square rosettes are often are installed at the corners of wood casing and trim, especially in the top corners of windows and doors, where they can replace or cover up an unsightly miter or butt joint installation.

Rosettes add decorative detail to moldings.

Round rosettes also can be attached to straight pieces of molding for purely decorative effect. You can finish rosettes to match the molding, or apply a different color if you want to create a focal point.

  1. Position the square rosette on the corner joint of the window or door casing. Make sure it is flush with the edges of the casing. Mark the position with a pencil for later reference.

  2. Apply wood glue to the back side of the rosette. Position the rosette against the casing, along the pencil marks.

  3. Drive a finish nail through each corner of the rosette block. Position the nails approximately 3/8 inch from each corner.

  4. Set the nail 1/16 inch below the surface of the rosette block using a nail set. Place the narrow end of the nail set over the head of the nail, then strike the other end with a hammer.

  5. Apply wood putty to each nail hole with a putty knife. Fill the hole so that it is slightly raised, to allow for shrinkage as the putty dries. Allow the putty to dry completely.

  6. Sand the putty with fine-grit sandpaper until it is flush with the surface of the wood. Rub the sandpaper in the direction of the wood grain.

  7. Apply stain or paint to the rosette. Allow the finish to dry.

  8. Tip

    Apply rosettes to the top corners of window and door casing. Use plinth blocks to complete the effect on the bottom of the casing.
