The brush used for painting

The underlying surface or material being painted

In painting terminology, "substrate" refers to the underlying surface or material that is being painted. This could include various surfaces such as wood, metal, drywall, concrete, or any other material that needs a coating to protect it or enhance its appearance. Understanding the substrate is crucial for selecting the appropriate paint and preparation method, as different substrates may require specific treatments or primers to ensure proper adhesion and longevity of the paint.

For instance, painting on a wooden substrate may necessitate sanding and sealing to prevent moisture damage, while a metal substrate might require a rust-inhibiting primer. The properties of the substrate will influence the final outcome of the paint job, such as durability and finish quality.
