Priming tools are instruments used to prepare surfaces for painting or finishing. They help ensure that the paint adheres properly and provides a smooth, even finish. Common priming tools include brushes, rollers, and spray guns, which can apply primer to various surfaces like wood, metal, or drywall. These tools are essential in the painting process, as they help seal the surface and prevent issues like peeling or uneven color. Using the right priming tool can enhance the durability and appearance of the final coat, making it an important step in projects involving home improvement or art.
