Substrate is defined as what?

• A. The surface color.
• B. Material underneath the paint.
• C. Primer type.
• D. A painting technique.

Answer: (B)

Substrate refers to the material underneath the paint—the surface you apply coatings to, such as wood, drywall, metal, or plaster. Knowing the substrate matters because it determines how you prepare the surface, how well coatings will adhere, and what kind of primer or coating is appropriate. It also helps in assessing any lead risk and choosing proper containment and cleanup practices. Surface color is just how it looks, not the material beneath. Primer type is a coating you apply on top of the substrate, not the substrate itself. A painting technique describes how you apply the paint, not what you’re applying it to.
