Primers play a crucial role in the refinishing process primarily by serving as a base for paint adhesion. This is important because the surface of the material being painted often has characteristics that might hinder the paint bond, such as being smooth, glossy, or contaminated with oils or dirt. A primer creates a better surface texture and promotes strong adhesion between the substrate and the topcoat.

Moreover, primers can also help in blocking stains and preventing the bleed-through of underlying colors, thus ensuring a uniform appearance of the final paint. Properly applied primer reduces the risk of peeling and chipping, which can lead to premature failure of the paint job. While enhancing color vibrancy, preventing rust, and increasing thickness may have their own advantages, these aspects are secondary to the primary function of ensuring that the paint adheres effectively to the surface for a durable finish.
