An adhesion primer is a type of primer specifically formulated to improve the bond between a surface and the topcoat of paint. It is designed to adhere strongly to difficult or non-porous surfaces—such as glass, tiles, plastics, metals, or glossy finishes—where standard primers or paints might not stick effectively.
In the painting and decorating industry, especially in Australia, adhesion primers are commonly used in both residential and commercial projects to ensure long-lasting paint performance. They help prevent peeling, flaking, and premature paint failure by creating a stable base for subsequent coats.
Key features of adhesion primers:
- Excellent bonding to slick or hard-to-paint surfaces
- Can be used on a variety of substrates (e.g., PVC, aluminium, ceramic tiles)
- Often water-based or solvent-based, depending on the application
- May be referred to as "bonding primers" or "problem surface primers"
Example use: Before painting over a glossy laminate kitchen cabinet, a painter would apply an adhesion primer to ensure the topcoat adheres properly and lasts longer.
