How To Make Your Windows Pop With Paint

Over the all-white Instagram aesthetic, but not ready to go wall-to-wall bright? Consider this easy DIY a gateway to the world of colour.

When it comes to paint, sometimes less is more. In her living room, Chatelaine editor Maureen Halushak opted to paint her window trim a punchy shade of blue to inject some personality into the white space. With the help of Toronto-based decorator Elias Blunden-Stone (a.k.a. The Room Editor), she picked Benjamin Moore’s Delphinium CC-872 to make her accessories stand out and create continuity with the wallpaper in the hallway, which has a floral pattern with a similar shade of blue. His top tip for picking an accent hue? Look around the room. “I work with what people have,” he says. “I often pull colours out of book spines, photo frames or record covers—my goal is to help people find and amplify their style based on what’s already there.”

  • Paint for trim
  • 2.5-in. angled brush
  • Painter’s tape
  • Drop cloths
  • 120 grit sandpaper
  • Rag
  • Leftover wall paint for touch-ups
  • Small paint brush

Step 1: Pick your paint

Some paint finishes are more durable than others and give different results. High-gloss paint is durable and impactful, but tends to highlight imperfections and unevenness in the surface, while matte paint is forgiving, but more likely to get damaged. For this project, we opted for semigloss for a fuss-free and durable high-impact finish.

Pro tip: The type of paint you should use depends on what the surface is made of. If you’re painting over wood, a water-based product is the way to go.

Step 2: Sand

“The number one mistake people make when painting is not sanding,” says Benjamin Moore colour and design expert Sharon Grech. “Roughing up the surface allows the new coat of paint to adhere to the trim better.”

Pro tip: Use a fine grit (we went with 120 grit sandpaper) and keep a damp rag on hand to wipe off the residue.

Step 3: Tape

With painter’s tape, tape the wall and the casing along the trim to protect surfaces you don’t want to paint. To avoid bleeding, “take your thumb and rub along the edge of the tape to make sure it’s smooth,” Grech says.

Pro tip: To make removal easier, work with long strips of tape instead of piecing smaller ones together.

Step 4: Paint

Using a 2.5-in. angled synthetic brush, apply two to three coats of colour, letting the paint dry completely between each coat. (Follow the paint company’s guidelines.) Grech recommends painting in light coats for a smoother final result.

Pro tip: As a general rule of thumb, there’s no need to prime when painting wooden trim, she says.

Step 5: Touch-up 

Use a small craft brush to fill in any missing spots or tight corners, where the angled brush can’t reach. And make sure to use a quality brush—you don’t want to have to pick bristles out of your paint job.

Pro tip: Have leftover wall paint? Use it to go over any spots where the trim colour has bled.

Step 6: Tape removal

Peeling off the tape too soon can result in bleeding. “But don’t wait until the paint is dry,” warns Grech, noting that it can cause paint to chip off and ruin your crisp line. Let the paint get dry to the touch, then remove.

Pro tip: Slowly pull off the tape at a 45-degree angle, moving away from the trim to avoid touching the paint.

Done with your project? Here’s how to care for your paint brushes.


  • Plastic wrap
  • Elastic band
  • Dish soap

Wrap them up

Between coats, tightly wrap your brushes in plastic wrap and secure them with an elastic band to keep them from drying out. This method also works overnight if you need to put your project on hold and don’t have time to clean and dry your brushes.

Rinse after use

When you’re done painting, rinse brushes with warm water, paying special attention to the base, where paint tends to get stuck. (Dry brushes are much harder to clean!) If needed, use a little dish soap. Grech advises against soaking brushes.

Lay your brushes flat to dry to avoid damaging the bristles. Grech also likes to roll the handle of her brush rapidly between her palms to get rid of excess water. (It can get messy, so make sure your sink is deep enough before trying this at home.)
