If you’ve been thinking about refreshing the look of your home, painting your aluminium window frames can make a significant difference.

With the right tools and techniques, the process can be straightforward and rewarding. Let’s dive into the details of how to paint aluminium window frames.

Why Consider Painting Aluminium Window Frames?

Aesthetics and Style

  • Freshen Up the Look: Over time, aluminium frames can fade or become dull. Painting can rejuvenate their appearance.
  • Personalization: With a myriad of paint colors available, you can match your frames to your home’s overall color palette.

Protection and Durability

  • Aluminium window frames can corrode over time. A fresh coat of paint provides an additional barrier against rust and weather-related damage.

How to Paint Aluminium Window Frames: A Step-by-Step Guide

Materials You’ll Need

  • Soap and water for cleaning
  • Sandpaper (medium and fine-grit)
  • Primer (designed for metal surfaces)
  • Paint (preferably formulated for metal surfaces)
  • Paintbrushes or rollers
  • Masking tape
  • Protective gear (gloves, goggles, mask)


  1. Clean the Frames: Begin by cleaning the aluminium window frames with soap and water. Ensure all dirt, grease, and grime are removed.
  2. Sand the Surface: Lightly sand the frames using medium-grit sandpaper. This roughens the surface allowing the primer to adhere better. Finish with fine-grit for a smooth finish.
  3. Mask Adjacent Areas: Use masking tape to protect areas you don’t want painted, such as the glass or the wall surrounding the frame.

Painting Process

  1. Apply Primer: Use a brush or roller to apply a thin, even coat of primer. Let it dry thoroughly.
  2. Paint the Frames: Apply the paint in thin, even strokes. Multiple coats might be required for a smooth, glossy finish. Always allow ample drying time between coats.
  3. Remove Masking Tape: Once the paint is dry, carefully remove the masking tape.

Tips for the Best Results

  • Choose the Right Time: Paint on a dry day with little to no wind. Extreme temperatures can affect paint adherence and drying times.
  • Test Paint First: Before painting the entire frame, test a small, inconspicuous area to ensure the color and finish are to your liking.
  • Maintenance: To keep your painted frames looking their best, clean them periodically and consider repainting them every few years.


Q: How long does it take for the paint to dry on aluminium window frames?

A: Typically, it takes 2-4 hours for the paint to touch dry, but it’s best to leave it for at least 24 hours for complete drying.

Q: Can I use spray paint instead of traditional paint?

A: Yes, spray paint can be used, but ensure it’s formulated for metal surfaces. It’s also essential to work in a well-ventilated area and use protective gear.

Q: How often should I repaint my aluminium window frames?

A: Depending on the quality of paint and external conditions, repainting every 3-5 years is recommended to maintain aesthetics and protection.


Knowing how to paint aluminium window frames is a valuable skill for homeowners looking to rejuvenate their homes. The process, while requiring attention to detail, can offer gratifying results. With the right preparation and tools, you can breathe new life into your aluminium window frames, ensuring they remain an attractive and durable feature of your property for years to come.
