ASE Painting and Refinishing (B2) Practice Test

Question: 1 / 650

What are the two goals of a primer-surfacer?

To add color and create gloss

To provide hiding characteristics and build a smooth film

The primary goals of a primer-surfacer focus on the preparation of the surface to ensure that the topcoat adheres properly and provides an even finish. Achieving hiding characteristics is crucial because it helps conceal any underlying colors or imperfections in the substrate, creating a solid foundation for the subsequent layers of paint. Building a smooth film is equally important, as it ensures that the surface is flat and uniform, which contributes to the overall quality and appearance of the final paint job.

In this context, while enhancing durability and improving adhesion are often related to the overall function of primers, the specific objectives of a primer-surfacer center around providing coverage and achieving a smooth, even appearance prior to applying topcoats. The correct answer encapsulates these essential functions, making it the best choice to highlight the dual role of primer-surfacers in automotive refinishing.
