Term: intercoat

In painting and coatings, the term "intercoat" refers to a layer of paint or coating that is applied between other layers—typically between a primer and a topcoat, or between multiple topcoats. It serves as an intermediate layer that can enhance adhesion, build film thickness, improve durability, or provide specific performance characteristics such as colour uniformity or chemical resistance.

In professional painting and coating systems (especially in automotive, industrial, and protective coatings), intercoats are often used to:

• Promote adhesion between layers
• Prevent delamination or peeling
• Provide a smooth surface for the next coat
• Enhance appearance, such as gloss or colour depth
• Act as a barrier to prevent bleed-through or chemical reactions between layers

In the context of Australian painting standards, using the correct intercoat and following the recommended intercoat drying or recoat times is essential to ensure the longevity and performance of the coating system.
