Term: adhesion

« Back to Glossary Index

Definition of “adhesion” by Brushworks Painting: In painting and surface preparation, adhesion refers to the ability of a paint, coating, or sealant to stick or bond effectively to a surface or substrate. Good adhesion ensures that the coating remains firmly attached over time, resisting peeling, flaking, or blistering.
Adhesion is influenced by several factors, including:

Surface preparation (cleanliness, dryness, and texture)
Compatibility between the substrate and the coating
Environmental conditions during application (temperature, humidity)
Use of primers or bonding agents

In the context of professional painting in Australia, ensuring proper adhesion is critical for durability, appearance, and compliance with industry standards such as those outlined by AS/NZS 2311:2017 – Guide to the painting of buildings.
