When the paint around your windows starts to peel or lose its color, it’s easy to notice. The trim might seem like a small detail, but it plays a big part in how your home looks from the outside.
Knowing how to paint exterior window trim the right way can make your home look fresh again and help protect it from sun, rain, and temperature changes.
In Highlands Ranch, CO, homes deal with a mix of hot summers, dry air, and cold winters. That kind of weather can wear down even the best paint. A careful repaint not only brings back the color but also keeps the trim sealed and safe from damage.
Before we jump into the process, let’s go over some basics that matter more than most people think.
Key Takeaways:
- Proper prep work like cleaning, sanding, and priming helps paint stick and last longer.
- Use acrylic exterior paint for flexible, weatherproof coverage in Colorado’s climate.
- Wood, metal, and vinyl trims each need different primers for strong adhesion.
- Caulking gaps before painting keeps out moisture and prevents early cracking.
Know Your Exterior Trim Material
Before picking up a brush, it helps to know what your trim is made of. Different materials need slightly different prep and paint types.
- Wood Trim: Wood is common because it’s easy to shape and looks great. But it also absorbs moisture. You’ll need a quality primer to seal it before painting. Once the surface is sealed, a durable acrylic paint works best for flexibility and weather resistance.
- Metal Trim: You’ll often find metal trim around modern windows. Make sure to remove any rust spots with sandpaper, then apply a primer designed for metal. Without primer, paint won’t stick properly.
- Vinyl or PVC Trim: These materials don’t absorb paint as easily as wood, so adhesion is key. Choose a bonding primer before applying your exterior paint.
- Fiber Cement Trim: This material handles the weather well but needs a good clean surface. Use caulk to seal any gaps before exterior painting.
Each material reacts differently, so using the right primer, sanding correctly, and choosing quality paint will make or break your finish. For more about paint options, you can check Exterior Paint Types to understand which one lasts best outdoors.
Gather Your Painting Supplies
A successful project starts with the right tools. You’ll need:
- Exterior-grade paint and primer
- Fine- and medium-grit sandpaper
- Putty knife for scraping off old paint
- Painter’s tape and drop cloths
- Caulk for sealing cracks
- Small and medium brushes
- Cleaning cloth or vacuum for dust
- Ladder
Having everything ready saves you time once you begin painting.
Preparation Makes All the Difference
Painting is 70% prep and 30% painting. Before you start, give your trim a proper cleaning. Remove dirt, cobwebs, and mildew using a mild soap-and-water mix. Any surface debris will stop paint from sticking.
Next, scrape away peeling paint using your putty knife, and sand the surface until it feels smooth. Use medium-grit sandpaper first, then switch to fine-grit for a cleaner finish. Wipe away all dust with a damp cloth before priming.
If you see any gaps between the trim and the wall, seal them with caulk to block moisture. It keeps water from seeping in and ruining your fresh coat later.
For wood trim that’s exposed to moisture, use a stain-blocking primer to improve adhesion. If you’re curious how primer bonds and protects the surface, the Paint Film Formation Process on Exterior Surfaces explains that in detail.
Choosing The Right Paint For Highlands Ranch Weather
Colorado’s weather can shift quickly—from dry summer heat to cold, snowy winters. That’s why choosing a durable acrylic paint is key. Acrylic formulas stay flexible and resist cracking even in temperature swings.
Stick with exterior-specific paints from trusted brands like Behr, which offer excellent coverage and color retention. Semi-gloss or satin finishes work well for window trim since they’re easier to clean and repel water.
Before painting, check your forecast. Avoid painting on rainy or windy days since dust and moisture can ruin a fresh coat.
Step-By-Step: How To Paint Exterior Window Trim
Now that everything’s prepped, it’s time to paint. Follow these steps for a smooth and lasting result.
1. Tape Off The Area
Use painter’s tape to protect your glass and siding. This will give you crisp, straight lines when painting around the windows.
2. Apply Primer
Start with a coat of primer to help your paint grip and to seal the surface. Let it dry completely before moving to the next step.
3. Paint The Trim
Using a medium brush, start from the inner edge of the trim and move outward. This helps control drips and keeps your strokes even.
4. Add A Second Coat
After the first coat dries, add a second for durability and richer color. Make sure the paint is completely dry before removing the tape.
5. Touch-Ups
Inspect your work in daylight. If you see uneven spots or drips, lightly sand and apply another thin coat.
Common Mistakes To Avoid
- Painting over dirty or wet trim
- Skipping primer
- Ignoring cracks or caulk gaps
- Using the wrong brush size
- Rushing between coats
Each of these can cause paint to peel, bubble, or fade prematurely. Taking the time to prep right saves you from redoing the job next season.

Maintenance Tips For Long-Lasting Results
Once your exterior window trim looks fresh, keeping it that way is easy with a little maintenance.
- Clean the trim yearly to remove dust and mildew buildup.
- Check for cracks in the caulk or paint film every spring.
- Touch up chips with leftover paint to prevent water damage.
- Keep your brush and tools handy for quick fixes.
Regular upkeep extends the life of your paint job, saving you time and money in the long run.
