Before applying the first coat of paint, several important steps need to be taken to ensure a smooth, lasting finish. Initially, the surface to be painted should be thoroughly cleaned to remove any dust, dirt, or grease. Any necessary repairs, such as filling in holes or smoothing out rough patches, should be completed next. Once the surface is clean and repaired, a layer of primer is applied. The primer helps the paint adhere to the surface and enhances its durability. Finally, after the primer is dry, the first coat of paint can be applied.
