Do I Need to Prime Aluminium Window Frames Before Painting? | Gold Coast

Yes — aluminium window frames must always be primed before painting.

Aluminium is a smooth, non-porous surface. Without primer, paint has nothing to grip to. Skipping primer means the topcoat will peel, chip, or flake within months.

Why Primer Is Essential

Adhesion → Primer bonds to aluminium and gives the topcoat a keyed surface.

Durability → Stops paint from lifting or bubbling.

Smooth finish → Levels the surface before spraying colour.

Corrosion resistance → Especially important on older frames and coastal homes.

Types of Primers for Aluminium

There are two main systems, depending on the job:

Single-Pack Primers (Residential)

High-quality all-surface primers designed for aluminium.

Used on homes across the Gold Coast for windows, sliding doors, and screens.

Provides excellent adhesion and durability when paired with professional spraying.


2-Pack Primers (Commercial/Industrial)

Epoxy-based, two-component primers.

Used on shopfronts, warehouses, and large commercial projects.

Extra tough, chemical- and abrasion-resistant for heavy-use environments.
