How to Paint Aluminium Doors?
Aluminium doors have undergone a serious makeover in recent years, transforming from their once functional but outdated designs into sleek and contemporary features that any homeowner would take pride in.

With excellent durability and stability, aluminium is a perfect frame material for doors of any size and type – including aluminium bi-fold and sliding patio doors. Their lightweight, slimline appearance gives your home an exceptionally stylish exterior finish, while flooding your home with natural light. It’s not surprising that aluminium frames have fast become the preferred choice over uPVC for many homeowners across the country.
If your aluminium door is made using high quality and weather-resistant materials, you shouldn’t need to paint your door for many years. At Majestic Designs, all of our products come with a ten-year warranty.
However, if you fancy giving your home an affordable refresh with a new pop of colour, painting your aluminium doors can transform the inside and outside of your house.
A STEP-BY-STEP GUIDE TO PAINTING ALUMINIUM DOORS
Prepping
Before beginning the painting process, aluminium doors need to be thoroughly cleaned to eliminate dirt and grease. A clean, dry surface helps to create a better bond with the paint.
Trying to paint around hardware is time-consuming and can make your paint job look messy and unfinished. If possible, remove any glass panels or cover them with newspaper and secure with masking tape. Likewise, handles or fittings that aren’t easily removable should be covered and taped.
Priming
For a long-lasting finish on your aluminium doors, priming is an absolute necessity. A self-etching primer is the best choice for aluminium, as it contains chemicals that etch into the surface for the best bond.
Sanding is optional, but will help to give a smoother finish if your door feels very bumpy or uneven after priming. This step is especially relevant when dealing with a powder coated aluminium door, as sanding its slick surface down will enable you to paint more effectively. If you choose to sand, remember to clean the door again to remove any residual dust or particles.
Painting
When it comes to painting aluminium, it’s important to ensure your paint is compatible. Acrylic and epoxy are the best options when painting your door at home. Acrylic paint is a reliable and cost-effective choice due to its good adhesion, durability and resistance to fading. Epoxy, on the other hand, provides long-lasting endurance and chemical resistance that outshines the features of acrylic paint.
Apply each coat with slow, deliberate movements using a brush, roller or sprayer. Precision is paramount to avoid unattractive strokes, paint blobs and the risk of damaging hardware.
Allow each layer to dry completely before applying another. It’s better to apply lots of thinner coats compared to fewer thick ones. Once you’ve achieved your desired colour and density, it’s time to bring your hard work to life with some finishing touches.
Aftercare
To protect your newly painted aluminium doors against the elements, including rain, UV rays, and extreme temperatures, consider applying a protective sealant. This extra layer preserves the paint finish and enhances the longevity and overall performance of your doors.
The final step is to remove any protective coverings and reattach the hardware to your aluminium doors. If you notice any paint splatters on the glass, a specialised paint cleaner can effortlessly remove them.
CARE AND MAINTENANCE OF ALUMINIUM DOORS
Aluminium doors are known for their strength, durability, and low-maintenance features. However, like anything, it’s good to follow some simple care practices to keep your doors looking and functioning at their best.
- Cleaning: Using a soft sponge or cloth, give your frames and hinges a quick wipe with a mild detergent and some warm water. Don’t use harsh products or scouring pads on your frames, as this is likely to damage the aluminium and shorten its lifespan.
- Scratches: For scuffs and small marks, non-abrasive liquid cream or paraffin cleaner can be used to remove marks effectively.
- Cleaning the Tracks: To maintain the proper functioning of your sliding patio doors, regularly clear out accumulated dust and debris between the rails using the small tip of your vacuum cleaner. For added protection to the finish, consider using a brush attachment.
- Lubricating Hinges and Locks: Over time, the moving parts of your doors may become stiff or noisy. Apply a small amount of lubricant to these mechanisms, including hinges, locks and moving parts at least once a year.
