How to Paint a Window

Window above steps on yellow colored walls

Windows can highlight and accentuate your home's most interesting features. Because of this, window casings are often painted with higher sheens, which naturally draw the eyes to the glossy surface.

For Best Results:

Allow enough time for the paint to dry fully before putting windows back into use. Otherwise, they will stick together.

Maintain your painted window frames and safely wipe away dirt and common household stains with BEHR SWIPES™ Interior Wall Wipes.

The Window Frame

  1. Step 1

    Begin your painting project by pouring your thoroughly mixed paint into a bucket and dipping a quality 2"-2½" wide nylon/polyester brush into the paint.

  2. Step 2

    With your brush, begin painting the inside frame of the window starting at the top of the frame.

  3. Step 3

    Continue until the inside frame is complete. Let it dry.

The Window Sash

  1. Step 1

    Raise the lower sash and drop the upper sash.

  2. Step 2

    With your brush, paint the upper sash beginning with the crossbar.

  3. Step 3

    Continue to the lower sash beginning with the crossbar. Repeat the process with the obstructed sash areas.

  4. Step 4

    Paint the window casing and sills. Let this dry.

The Window Trim

  1. Step 1

    Starting at a top corner of the window trim, begin painting the side edge of the trim where it meets the wall. Continue until all side edges of the trim are complete.

  2. Step 2

    Return to the top of the window trim and begin painting the face of the trim.

  3. Step 3

    Continue until the window trim is complete. Let it dry.
