Window trim is high-visibility and high-traffic — especially around locks, latches, and blinds. That means your paint needs to be durable, washable, and precise.

Priming is non-negotiable for clean coverage and long-lasting results. Use the right primer for your trim material:
Apply with a small angled brush, working from the inside edge of the frame outward. Let dry fully before sanding lightly and moving on to paint.
Want to ensure your primer and paint combo will last? Contact Integrity Painting for expert recommendations
Use long, even strokes with your angled brush and work in the same direction as the trim grain. For detailed areas:
Apply one thin coat, let dry, then apply a second coat. Avoid overloading your brush — this is where drips and uneven edges happen.

Some homeowners choose to paint the window frame along with the trim — especially if it’s metal or unfinished. Here’s how to approach it:
Be cautious: too much paint on the frame edges can cause the window to stick.

The secret isn’t tape — it’s technique. If you want to ditch the tape and still get crisp results:
Liquid mask or peel-away glass protectants are great alternatives if you don’t want to risk bleed-through with tape.

Q: Should I paint my window trim the same color as the walls?
A: You can! Matching trim creates a modern, seamless look. For contrast and definition, choose a shade or finish that stands out.
Q: What’s the best finish for window trim paint?
A: Semi-gloss or satin — they’re easy to clean, durable, and show off detail beautifully.
Q: Can I paint trim without removing it?
A: Yes. Just clean, sand, and tape (or use a steady hand) before painting.
Q: How long should I wait between coats?
A: Most interior trim paints require 4–6 hours between coats. Always check the can.
Painting window trim is one of those small upgrades that makes a big impact. With the right tools, prep, and technique, you can get crisp lines, vibrant color, and a polished finish — whether you’re going classic white or bold black.
