Repainting is the process of applying a new layer of paint to a surface, such as walls, furniture, or vehicles. This can refresh the appearance, protect the material underneath, and cover up any imperfections. Repainting can be done with various types of paint, including water-based and oil-based options, depending on the surface and desired finish. Before repainting, it is essential to prepare the surface by cleaning, sanding, or priming as needed. This ensures better adhesion and a smoother finish. Tools like brushes, rollers, and spray guns may be used to apply the paint evenly and efficiently, resulting in a professional-looking outcome.
