If the trim around your windows is starting to peel, fade, or look worn, a fresh coat of paint can make a big difference. Knowing how to paint exterior window trim correctly helps keep your home in Erie, CO, looking clean and well-maintained while protecting it from the sun, rain, and changing weather conditions.
Window trim might seem small, but it plays a big part in your homeโs overall look. Proper preparation, quality materials, and the right technique make all the difference in how smooth and durable the finish turns out.
Hereโs how to do it the right way from start to finish.
Key Takeaways:
- Always clean, sand, and repair trim before painting to help the new coat stick and last longer.
- Use primer on bare wood or metal surfaces to improve adhesion and prevent rust or peeling.
- Choose durable acrylic paint like Behr for smooth coverage that holds up to Erieโs changing weather.
- Apply two thin coats instead of one thick layer for an even finish and better durability.
How To Paint Exterior Window Trim?
1. Start With Inspection and Cleaning
Before you open the paint can, take a close look at your windows. Check for peeling paint, cracked caulk, mildew, or signs of rot on wood or rust on metal parts. Cleaning and prepping the surface is one of the most important steps.
- Use mild soap and water to wash away dust, dirt, and mildew.
- For metal trim, gently sand off any rust spots until smooth.
- Let everything dry completely before moving forward.
A clean surface helps new paint stick better and last longer through Erieโs mix of hot summers and snowy winters.
2. Scrape and Sand Away Old Paint
If your trim already has old or chipping paint, smooth it out before applying a new coat. This helps the next layer bond well and look even.
- Scrape off loose paint using a putty knife.
- Smooth rough spots with sandpaper (120โ220 grit works well).
- Wipe off leftover dust with a dry cloth.
This step might take a little time, but it prevents future peeling and gives the paint a clean surface to grip. You can learn more about fixing damaged areas from our blog on repair chipped paint.
3. Prime Before Painting
After sanding, apply a primer to seal the surface and improve adhesion. Itโs especially important if your trim is bare wood or metal.
- Pick a primer suited for exterior use.
- Use a quality brush for smooth coverage.
- Allow it to dry fully before adding the next layer.
If youโre unsure how much product youโll need, our paint calculator can help estimate the amount based on your trim size and surface type.
4. Choose the Right Paint
The paint you select will decide how well your trim holds up over time. Acrylic paint is a good choice for Erieโs climate since itโs flexible and resistant to cracking and peeling.
Choose a color that complements your homeโs exterior. Many homeowners trust brands like Behr for durability and long-lasting color. Stir the paint thoroughly before use, then pour a small amount into a tray for easier handling.
For best results, apply two thin coats instead of one thick layer. Thin coats dry evenly and create a stronger finish.
5. Painting Made Simple
Once everything is prepped, itโs time to paint. Take your time โ good technique gives a cleaner result.
- Begin at the top of the window frame and work your way down.
- Paint edges and corners carefully with your brush.
- Let the first coat dry completely before adding the second.
Avoid painting when itโs too hot, windy, or when dew is likely to form. Dry, mild weather is perfect for painting outside in Erie.

6. Finishing Touches
After the second coat dries, look over your work. Clean up any small drips or smudges right away so they donโt harden. Carefully remove any painterโs tape and check that all edges look clean.
Final checklist:
- Check for missed areas.
- Apply fresh caulk where needed.
- Remove leftover dust and debris.
Give the paint about a full day to cure before closing windows completely to avoid sticking.
Knowing When Itโs Time for a Repaint
Over time, the paint on your trim will fade or peel due to weather exposure. When that happens, repainting early helps you avoid more serious damage.
If you notice cracks or dull color, those are good indicators itโs time to refresh your trim. You can learn more about timing in our blog on signs to repaint your house exterior.
