Can You Recoat Aluminium Window Frames? | Gold Coast

Yes — aluminium window frames can be recoated, but only if the correct preparation is carried out and the previous coats are sound. Simply spraying over old paint without checking adhesion or sanding will lead to peeling and failure.

Key Factors Before Recoating

1. Condition of Existing Coating

If the old paint is flaking, blistering, or poorly adhered, it must be removed.

If it’s well-bonded, it can be sanded and used as a base for new coatings.



2. Surface Preparation

Thorough cleaning with wax and grease remover.

Mechanical sanding to create adhesion for the new primer and topcoat.

Dust removal before spraying.



3. Adhesion Testing

A simple cross-hatch or tape pull test shows whether the existing coating is strong enough to be recoated.

Priming and Recoating

If bare aluminium is exposed → apply a suitable single-pack primer (residential) or 2-pack epoxy primer (commercial/industrial).

If the old coating is sound and sanded → apply fresh primer and topcoats for a smooth, even finish.


Recoating without primer is a common shortcut that leads to failure.

FAQs – Recoating Aluminium Frames

Q: Can you spray straight over old paint?
Only if the old paint is perfectly bonded and has been sanded. Otherwise, it will peel.

Q: What if the old coating is peeling?
It must be stripped back to a sound surface, then reprimed.

Q: Do you use different products for homes vs commercial jobs?
Yes. Homes use single-pack primers and topcoats. Commercial work uses 2-pack primers and polyurethane finishes for maximum durability.

Q: Will the new finish look even if recoating over old paint?
Yes — as long as sanding and priming are done properly, the finish looks factory-fresh.
