Painting your exterior aluminum window trim is a fantastic way to boost your home's curb appeal and protect it from the elements. Aluminum trim, common in older homes, can be easily updated with a fresh coat of paint to match your desired aesthetic. This comprehensive guide provides you with the knowledge and steps to achieve a professional-looking finish that lasts.
Painting aluminum window trim offers several benefits:
Painting allows you to update the color of your trim to match your home's current style or to create a new look. Black window frames, in particular, create a striking contrast, enhancing curb appeal and complementing various architectural styles.
A fresh coat of paint acts as a barrier against weather damage, preventing corrosion and extending the life of your trim. It protects the aluminum from the elements, extending its lifespan.
Well-maintained and freshly painted trim enhances your home's overall appearance, potentially increasing its market value.
Painting is significantly cheaper than replacing windows, making it an attractive option for homeowners on a budget. It's a relatively inexpensive way to refresh your home's exterior compared to replacing the trim entirely.
Painting allows you to choose the exact shade to match your home's color scheme.
Before you begin, gather all the necessary tools and materials to ensure a smooth and efficient painting process. Here's a comprehensive list:
- Bucket
- Warm water
- Dish soap
- Rust-removing cleanser
- Scrub brush
- Clean cloths
- Wire brush (for removing rust)
- All-purpose cleaner
- Fine-grit sandpaper (120-grit and 240-grit)
- Painter's tape
- Drop cloths or plastic sheeting
- Vacuum
- Dust brush
- Metal-specific primer (self-etching primer for aluminum)
- Exterior acrylic paint designed for metal surfaces
- Paintbrushes (small angled brush for edges and corners)
- Foam rollers (for flat sections)
- Paint bucket
- Stir stick
- High-quality black paint: Choose a paint formulated for exterior use with UV and weather resistance.
- Etch primer: Specifically designed for aluminum, to ensure proper adhesion

Proper preparation is crucial for achieving a long-lasting and professional paint job. Neglecting this step can lead to peeling, chipping, and an overall unsatisfactory result. Follow these steps to ensure your aluminum trim is ready for painting:
1. Mix warm water and dish soap in a bucket.
2. Use a scrub brush to thoroughly clean the aluminum surface, removing dirt, grease, mildew and other debris. Rinse with clean water and allow the frames to dry completely. This step is essential for ensuring the primer and paint adhere properly.
3. Rinse with clean water and wipe down with a clean cloth.
4. Allow the surface to dry completely.
1. If there's any rust, use a rust-removing cleanser to treat the affected areas.
2. For stubborn rust, scrub with a wire brush to loosen and remove it.
3. Smooth the surface with fine-grit sandpaper.
4. Wipe away any dust with a damp cloth and let it dry.
Sanding the aluminum surface is crucial for creating a smooth and receptive base for the paint.
1. Lightly sand the entire surface of the aluminum trim with fine-grit sandpaper (120-grit and 240-grit) to create a slightly rough texture. This will help the primer adhere better. If you spot any areas which are bubbling or corroding, sand them back with 120grit or similar until it's flat, then use 240grit on-top to smooth. Lightly sand the aluminum windows without adding much pressure to not create additional and unnecessary scratches. A wet sanding technique can also be applied by spraying water on the surface as it helps in removing surface scratches as well. Sand the aluminum window using a back-and-forth motion to easily remove scratches and blemishes.
2. Remove any flaking paint or imperfections.
3. Wipe the surface clean with a damp cloth and allow it to dry fully. After sanding, use a vacuum and a dust brush to remove any remaining particles.
1. Apply painter's tape to the surrounding glass, walls, and any other areas you want to protect from paint. Protect the glass, walls, and any other surfaces you don't want to paint by applying painter's tape. Be careful not to overlap the frame anywhere - you don't want the old colour coming through. Remember, it's easier to touch up where you accidentally sprayed the new frame colour, than it is to respray a section you missed later as you masked too close! So do not overlap the tape at all on the frame, even 1mm overlap will leave a noticeable line with the old colour!
2. Ensure the tape is firmly pressed down to create a clean, sharp line.
1. Place drop cloths or plastic sheeting underneath the work area to protect the ground and nearby plants from paint splatters. Cover larger areas with drop cloths or newspapers to prevent paint splatters.
Priming is a non-negotiable step when painting aluminum windows. Skipping this step or using the wrong primer will lead to peeling and an uneven finish.
Select a self-etching primer specifically formulated for aluminum or metal surfaces. This type of primer chemically bonds to the aluminum, creating a durable foundation for the paint. An etch primer is essential for painting aluminum because it bonds to the metal and provides a surface that the paint can adhere to.
1. Stir the primer thoroughly.
2. Apply 2-3 thin coats of primer for best results which can be applied with a spray can or with a regular brush, allowing 5 minutes in between coats for it to dry.
3. Use a small brush or roller to apply a thin, even coat of primer, ensuring all areas are covered.
4. Avoid applying the primer too thickly, as this can lead to drips and an uneven finish.
5. Apply the primer in thin, even coats, allowing each coat to dry completely before applying the next.
Allow the primer to dry completely according to the manufacturer's instructions. This is crucial for proper adhesion of the paint.
With the preparation complete, you can move on to the painting process. Follow these steps for a professional and durable finish. Once the primer is completely dry, you can begin painting the aluminum trim.
Choose an exterior acrylic paint designed for metal surfaces. This type of paint is weather-resistant and flexible, allowing it to expand and contract with temperature changes without cracking. High-quality exterior paint with a high acrylic or urethane resin level is essential for better adhesion and durability. Consider using a higher sheen paint for your trim, as it is more durable and highlights your home's architectural features. Avoid using dark colors for aluminum windows, especially in areas with intense sunlight, as dark colors absorb more heat, which can lead to warping or distortion of the aluminum over time. Use a high-quality acrylic paint or a specialized aluminum paint. These paints are designed to adhere to metal surfaces and withstand the elements. Choose a finish that complements your home's style. Popular options include matte, satin, and gloss. Opt for a paint with UV-resistant properties to prevent fading and discoloration over time. Select a paint that is resistant to rain, snow, and extreme temperatures to ensure long-term durability.
1. Stir the paint thoroughly with a stir stick.
2. Pour the paint into a clean paint bucket.
3. Use a high-quality angled brush for edges and tight corners and a foam roller for flat sections to ensure a smooth finish. Once the primer is fully dry, apply the black paint. Use a high-quality paint that is specifically formulated for exterior use and has UV and weather-resistant properties. Apply the paint in thin, even coats, using a brush, roller, or spray gun. If spraying, hold the can 6 to 8 inches from the surface and move it with a steady back-and-forth motion. Allow each coat to dry completely before applying the next. Depending on the paint and the desired look, you may need two or three coats for full coverage.
4. Apply the paint in thin, even layers to avoid streaks and drips. Apply thin, even coats of paint to prevent drips and runs.
5. Maintain a wet edge to prevent lap marks. Reload the brush when necessary to maintain a wet edge.
6. If painting a double-hung window frame with multiple panes of glass, use a small brush or roller for precise application around each pane. Be careful not to overload your brush or roller with too much paint, as this can cause drips or smudges.
1. Let each coat dry completely before starting the next layer, typically waiting about 24 hours between coats. Allow the paint to dry completely, following the manufacturer's instructions for drying times. This may take several hours or even overnight, depending on the paint and the weather conditions. Ensure the paint is fully dry before removing the painter's tape.
2. For full coverage, it may take up to three coats. You typically need to apply two to three thin, even coats of paint to aluminum windows for full coverage and a durable finish. Allow each coat to dry completely before applying the next.
3. When applying multiple coats, make sure to lightly sand between each layer with fine-grit sandpaper to smooth out any imperfections and ensure that subsequent coats adhere properly.
4. Apply additional coats until you achieve your desired level of coverage and color depth. Keep in mind that darker colors may require more layers than lighter ones.
5. The drying time will depend on the type of paint and weather conditions in your area. Check the manufacturer's instructions for specific drying times.
