Substrate
A substrate is the base surface or material that receives paint or coating in the painting industry. Think of it as the "canvas" that painters work with - it could be wood, metal, plastic, concrete, or any other material that needs to be painted. Understanding substrates is crucial because different materials require different preparation methods and paint types to ensure proper adhesion and a lasting finish. When you see this term in resumes or job descriptions, it typically refers to a painter's experience with preparing and painting various types of surfaces.
