For contemporary houses and businesses, aluminium doors are a chic and long-lasting option. They might no longer suit your design tastes, though, or they might begin to appear worn out over time. When compared to replacing aluminium doors completely, painting them is a great method to give them a new look and feel and save money.
From preparation to the final coat, we'll go over everything you need to know about painting aluminium doors in this in-depth tutorial to guarantee a polished finish that endures.
1. Why Paint Aluminium Doors?
Your property's exterior can be completely changed by painting aluminium doors, which can increase curb appeal and add flair. The following are some explanations for why companies and homeowners decide to paint their aluminium doors:
a. Aesthetic Appeal
-
Customise the colour to suit your interior or exterior design.
-
Refresh worn or faded paint for a more modern look.
b. Cost-Effective Solution
-
Painting is significantly cheaper than replacing the doors entirely.
-
It’s a great way to extend the lifespan of older doors.
c. Protection
-
An additional layer of defence against weathering and corrosion is offered by applying a new coat of paint.
d. Increased Property Value
-
Your home's exterior appeal can be improved with a freshly painted door, which could raise its market value.
2. Can You Paint Aluminium Doors?
Aluminium doors can be painted, but doing so calls for the proper supplies and careful planning. Without the right priming and preparation, conventional paints may not cling well to aluminium due to its non-porous surface and inherent resistance to corrosion.
Key considerations include:
-
Surface Preparation: For best paint adherence, aluminium must be cleaned, sanded, and primed.
-
Paint Type: A strong and long-lasting finish is guaranteed when metal surfaces are painted with paints made especially for them.
-
Weather Conditions: To ensure adequate drying and curing, the painting procedure should ideally be carried out in warm, dry weather.
3. Materials and Tools Needed
Before you begin, gather the following materials:
-
Cleaning Supplies: Mild detergent, water, and a soft cloth or sponge.
-
Sandpaper: Medium-grit (120-150) and fine-grit (220-240) sandpaper.
-
Primer: Metal or aluminium-specific primer.
-
Paint: High-quality acrylic or enamel paint suitable for aluminium.
-
Paintbrushes or Rollers: Select premium synthetic brushes for intricate areas or high-density foam rollers for a smooth finish.
-
Masking Tape: To protect areas you don’t want to paint.
-
Drop Cloths: To cover the ground and surrounding areas.
-
Safety Gear: Gloves, goggles, and a dust mask.
4. Step-by-Step Guide to Painting Aluminium Doors
Step 1: Remove the Door (Optional)
Removing the door from its frame can facilitate and complete the painting process, but it is not necessary. For easier access to all sections, place the door on a sturdy workbench or sawhorse.
Step 2: Clean the Door
-
To get rid of filth, grease, and grime, thoroughly clean the door using a mild detergent solution mixed with water.
-
Rinse with clean water and allow it to dry completely.
Step 3: Sand the Surface
-
To get rid of any oxidation or leftover paint, softly sand the entire surface with medium-grit sandpaper.
-
To smooth the surface and provide a texture for the primer to stick to, use fine-grit sandpaper afterwards.
-
Wipe away dust with a damp cloth and allow to dry.
Step 4: Mask Off Areas
-
To protect handles, locks, glass panels, and other areas you don't want to be painted, use masking tape.
-
Cover the surrounding area with drop cloths to catch any drips or overspray.
Step 5: Apply Primer
-
Choose a metal primer specifically designed for aluminium surfaces.
-
Apply a thin, even coat using a roller or brush.
-
Allow the primer to dry completely, following the manufacturer’s recommended drying time.
Step 6: Paint the Door
-
Stir the paint thoroughly before use.
-
Apply the first coat of paint using a foam roller or synthetic brush for an even finish.
-
Allow the paint to dry as per the manufacturer’s instructions before applying a second coat.
-
For darker colours or high-gloss finishes, a third coat may be necessary.
Step 7: Reattach the Door
-
Once the paint is fully cured, reattach the door to its frame.
-
Remove the masking tape and clean any accidental paint splatters.
5. Common Mistakes to Avoid
a. Skipping Surface Preparation
-
Failing to clean or sand the aluminium can result in poor paint adhesion and a patchy finish.
b. Using the Wrong Paint
-
Not all paints are suitable for aluminium. Ensure you use metal-specific paint for long-lasting results.
c. Rushing the Drying Process
-
Allow sufficient time for each coat to dry completely to avoid smudging or uneven layers.
d. Painting in Poor Weather
-
High humidity or low temperatures can affect the drying and curing process.

Regular Cleaning: Wipe down the door with a soft cloth and mild detergent to remove dirt and grime.
