Can You Paint Aluminium Window and Door Frames?

One of the most popular choices for many homeowners and commercial property owners for that very reason; they are strong, durable and also sleek modern looking. A common question that frequently comes from those that already are or considering purchasing customized aluminium frames is if they can be painted.

This is a question we are often asked because not only do aluminium frames need refreshing or a new look over time but it's becoming a new aim for homeowners just to match the colour of their windows and doors to new design elements within their homes.

We will take you through how to paint aluminium window and door frames, best practices to get a professional end result, what the benefits of painting are, and the problems you may run into.

1. Why Are Aluminum Window and Door Frames Painted?

There are several reasons why homeowners or businesses might choose to paint their aluminium window and door frames:

Aesthetic Appeal

Aluminium frames are often offered in a limited number of prefinished colours such as silver, black or white. These colours are versatile, but they might not match the decors of your house or office. Painting the framing is a great way to be able to make the colour approximate your interior design or complement or contrast with the building's exterior.

To Enhance Curb Appeal

Painting your aluminium frames can help curb appeal of your home or commercial property. Windows and doors with a fresh coat of paint can make things appear newer, add to the value of the property and give it a neater, well maintained look.

Protection from the Elements

While aluminium is resistant to corrosion, a further layer of protection may be obtained by painting. UV rays and rain are just as harsh on metal as they are on man made plastic, but during time the metal will become dull or weathered by the exposure to these things. Painting the frame can help seal the surface you want to preserve, as well as prevent further rust or wear with the application of a coat of paint.

If you intend to repaint the interior or exterior of your home or simply redecorate or renovate, one simple option to merge old with new is by repainting the aluminium frames of the windows and doors.

2. Can You Paint Aluminium Frames?

Aluminium frames can be painted, but not all paint jobs are created equal, and to get a high quality, long lasting finish there are a few steps you need to follow when painting aluminium. If you do not properly prepare, the paint will not adhere well and can peel and chip over time. If you want to get the desired output, you should follow a proper procedure.

Aluminium Frames painting challenges!

• Surface Smoothness: Aluminium has a really slick, smooth surface which makes it very hard for paint to hang on to and so you need to treat the surface to ensure it's paintable. By the way, anodized or powder-coated aluminium frames are the most sensitive.
• Metallic Finish: Aluminium has a metallic finish that is often both reflective and not ideal to paint (although it is certainly possible), and paints are often required to guarantee good coverage and durability.

But if you use the proper techniques, aluminium window or door frames can be painted, too.

3. How to Paint Aluminium Frames?

You need to gather up the proper materials before you start the painting process. It is therefore important to have the right tools and products to allow a smooth and professional finish. Below is a list of the essential items needed:

Materials and Tools:

Cleaning Supplies:

• Mild detergent and water
• Sponge or soft cloth
• (For oil or dirt removal, degreaser optional)

Surface Preparation:

• Medium and fine grit sandpaper
• Optional for tougher surfaces, steel wool
• Primer for metal surfaces
• Painter's tape for clean edges.
• Protect surrounding surfaces by using drop cloths or plastic sheeting.

Paint:

• A latex or oil based exterior paint in good quality for metal.
• Special paint designed for use on aluminium or metal spray paint, for example epoxy, acrylic paints.

Tools for Application:

• For smaller areas Paintbrush works well.
• Roller (for larger areas)
• If you are using a spray can (for an even finish) you will need some spray paint.
• Paint tray

Safety Equipment:

• Gloves
• Protective eyewear
• A respirator or mask is used if you are spray painting.

Important Tips for Selecting the Right Paint:

• Choose Metal-Specific Paints: It is better to choose a paint which is made specifically for metal surfaces. These paints are intended to stick to metal and be as long lasting as possible to outdoor elements.

4. How to Paint Aluminium Window and Door Frames

If the aluminium frame already has old paint, old chipped or old peeling paint, it needs to be removed. Gently rubbing down the surface with medium grit sandpaper or a steel wool pad may also work. If you must paint over anodised or powder coated aluminium, lightly scuffing the surface will help the primer and the paint stick.

If you see signs of oxidation or a chalky finish on the surface you will need to clean with a heavy duty metal cleaner to remove oxidation prior to attempting to clean with the above products.

Step 1: Tape the Edges

Cover the areas around the window or door frame that you don't want to paint with painter's tape. It can also refer to the glass, adjacent walls or trim. When adding the paint, tape the edges neatly so that you have nice straight, clean lines. Do not forget to cover the surrounding areas with drop cloths or plastic sheets.

Step 2: Apply a Primer

The reason why priming is important for ensuring the paint adheres well, and gives an even and durable finish.

Apply a metal primer suitable for aluminium. Prime the surface with a brush or roller starting on one side and working across until you have provided an even coat. You can lightly coat spray paint without drips by spraying in a thin coat and quickly moving your hand.

Proceed to the next step after allowing the primer dry as directed by the manufacturer's instructions (typically 24 hours).

Step 3: Apply the Paint

After the primer is dry, then you can paint. Apply paint in thin layers for smooth, even coverage. They may be detailed with a paintbrush or covered with a roller. When using spray paint, keep the can at 6-12 inches from the surface and spray in light, even drabs.

Apply a second and a third coat of paint for best results allowing each coat to dry fully before applying the next. By doing this you will get a more durable professional finish and decrease the odds of streaks or uneven coverage.

Step 4: Allow the Paint to Cure

Once you have applied the last coat, let the paint completely cure. This will take anywhere between 24 hours and several days depending on what kind of paint was used. Be patient at that step and let the paint really dry before attempting to peel off any painter's tape or it gets in the frame to touch.

Step 5: Remove the Tape and Clean Up

When the paint has completely dried, very gently peel off the painter's tape. Then you can wipe any drips or spills up against the edges. Remove any protective sheets, drop cloths or other materials used in the painting process.

Step 6: Inspect the Finish

Lastly, inspect the finished surface to see that the paint is smooth, even, and dirt free. If you need to touch up in any areas, just paint another coat as needed.

5. How to Have a Successful Paint Job

• Take Your Time: If the process is rushed, uneven application or mistakes might be made. Put your time to go slowly and apply the paint in thin even layers.
• Avoid Painting on Humid or Wet Days: The adhesion and drying time of paint depends on humidity. The best results come from painting on a dry, calm day.
• Protect the Glass: When painting near glass, make sure you don't get paint on the panes. However, if you do have paint, clean it up straight away with a razor blade or paint remover before it dries.
• Choose High-Quality Materials: Quality high quality paint, primer, and brushes or rollers can make a big difference in the project you are working on.

How Long Will the Paint Last?

Aluminium frames can be painted for around 5 – 10 years (depending on the type of paint used, and climatic conditions as well as how much exposure to sunshine and weathering) if applied properly.

While painted finishes add a certain amount of durability to painted frames, a regular maintenance regimen, which involves cleaning the frames, touching up any minor chips, or scratches, will go far in extending the life of these finishes.

Conclusion

Customized aluminium window and door frames can be painted, definitely, and usually with good results when a decorative finish is required. When done right, brush painting requires the right cleaning, priming, and selecting the right paint that will yield a professional, long lasting finish.
